90% of my driving is now on straight 4 lane highways, so razor sharp handling isn't the priority for me it once was. If I can get it, great, but I won't give up comfort for it.
I currently have Firestone Firehawk SH30's on the car. See my previous posts for my view of them.
It's been a few years since I've been above 110mph for any significant amount of time, so I don't need a V or Z speed rated tire. Anything rated T or better would be fine.
Treadwear isn't a major concern. As in the handling, if a good riding tire happens to have a great treadwear rating, good, but it isn't a priority.
I'm now driving about 35 to 45K per year, almost all highway. Since I spend so much time on the road, I want to be comfortable.
The tire size is 225/60/16. Here are a few that I'm currently considering (in no particular order):
Goodyear Aquatread 3 (T speed rated and has excellent ratings/comments at Tirerack.com)
Bridgestone Turanza Revo series (H, V and Z speeds with good to excellent ratings)
Several different Michelins (all in the XGT series, not rated very well at Tirerack, but highly recommended in the Seville forum)
I'm even considering trying a 'tire store' brand. We have a couple of 'Big O' tires stores here that have a tire called 'Legacy Tour Plus' available in various speed ratings. I've spoken to 2 people that have them, and they love the tire, claiming it's the smoothest, quietest tire they've ever had and that it has excellent rain and good snow traction.
The only reason I'd ever even consider a store brand tire is that they have a 100% refund guarentee on it. If I don't like it, I can have them removed and get my money back, or apply the money toward a different tire. Since they also carry Michelin and Goodyear, and they're the local recommended installer for tires purchased at Tirerack.com, I'm thinking of giving them a try. Any and all opinions regarding Big O or their tires would be welcome.
One other question: Does anyone know if a 225/65/16 tire will fit on the 95 STS? The increased sidewall height should make the ride even better, at the price of a little steering responsiveness.
Please note: I'm not a 'blue hair' that got talked into the wrong car. I'm 39 and have had this car for 3 years. The STS (even with the Firestones) rides and handles better than any other car I've owned, and I love the power! I intend to keep this car until it's worn out, but at 101K I've had no problems (well, I did have to replace the water pump belt) it doesn't use/leak any oil (down less than 1/2 quart at the regular 5000 mile changes I do) and it's still almost like new inside and out. Even the melted M&M's, and spilled fruit juice from my 3 and 4 year olds have wiped right off the leather seats. :-)
The type of driving I do has changed in this past year; instead of spending about 75% of my time on twisting 2 lane roads in southern Missouri, I'm now doing about 90% straight highway miles and I'm looking for a tire to match the change.
Sorry for such a long post, but I wanted to make sure everyone understood what I was looking for before making a recomendation.
Thanks in advance for any advice.
1. Michelin Energy MXV4+. It will do everything you need it to and has it's priorities the same as yours. Prolly the best choice for someone who wants a tire that's smooth, comfy, a bit sporty, and give long mileage. Comes in H and V.
2. I've heard good things about the Bridgestone Turanza Revo. So I'll rank them #2.
3. Michelin X-One. Does most everything well but sacrifices sportiness and responsiveness for long tread life. Not speed rated.
I think you need H-rated at a minimum and strongly suggest V-rated. It's not about speed. It's about construction quality and design. It's about superior materials used in the speed rated tire. Your STS is a heavy car with most of its weight over the front two tires. It's even more important on the Caddy to have top-notch tires as the suspension design will put incredible stress and pressure on the front two. I'm willing to bet that a speed rated tire will even last longer.
Let's see what others suggest.
Bret's suggestions seem to be great. Consumer Reports gave the MXV4+ a good rating for snow performance considering that it is an all-season touring tire. FWIW, MB uses these (V-rated version) tires for their C-class, E-class, and S-class sedans.
Good luck!

Thank you for your help. It seems that most of the survey top models do not come in my size.

Thank you too. I think you're speaking about the Pirelli P6000 Sport Veloce which does not come in my size. It snows here in the Northwest, some years more than others, and as you suggest it doesn't snow so much as to need dedicated snow tires.
I have no idea how to explain the difference in the tires behaviour. It can be related to suspension, weight of car per axle, tire inflation, and/or miriad of other reasons.
I do not think the pure difference in size does matter so much. However, according to Firestone, the 225/60-16 size is the largest available with SH-30:
http://www.bridgestone-usa.com/products/fhsh30tec.htm
and extremalities are often revealing hidden bugs. The same with the unusually high weight of your car.
Concerning the weight distribution: I am inflating the Malibu tires to 32 psi front / 29 rear. The difference between front and rear pressure was recommended by GM, and, in my experience, is important with sharp turns at higher speed. I only added 3 psi both front and rear.
The most strange for me is bad resistance to hydroplaning when your tires were new. Practically all tires resist hydroplaning well when new, i.e. while the tread is deep; additionally, the SH-30 thread pattern have deep and wide groves.
I want to thank you for the info. It is very useful for me personally. I planned to buy SH-30 when it will be time to junk the OEM Goodyear Eagle LS currently installed on my other car, Buick Regal. However, the tires are of the same size, 225/60-16. With the information you provided, most probably will buy something else. Possibly, the new Bridgestone Potenza RE950.
Thank you so much.
I have them on my 95 Jag (Which I dont even drive anymore!) and I am very impressed.

The most strange for me is bad resistance to hydroplaning when your tires were new. Practically all tires resist hydroplaning well when new, i.e. while the tread is deep; additionally, the SH-30 thread pattern have deep and wide groves.
I can't explain it either. About 1 month after the SH-30's were put on, I was cruising (if I remember right, I was doing about 70mph) down an Interstate during a moderate rainstorm. Suddenly the front end wasn't connected to the road anymore. The traction control kicked in and I thought "that must have been a deep puddle that I didn't see." But it kept happening where ever there was a little standing water.
If the road is just wet with no puddles, the tires are fine. Dry steering response and cornering is good (except the tires seem to squeal a little earlier than I'd expect) but straight ahead traction, both acceleration and braking, is less than what I was used to.
I run them at 33lbs, both front and rear, which is what Cadillac recommends. Since they are wearing evenly, I haven't experimented with different pressures.
I wonder if the 10mm increase in width might be a factor. Maybe the side sipes are large enough to shed water from a 215mm but not quite big enough for 225? Any tire engineers out there that can shed some light on this?
A couple of people have mentioned the weight and/or the weight distribution on the STS. While it is a fairly heavy car at around 4000lbs, I do computer networks, and normally carry 300 to 500 lbs of routers, UPS's, spare PC parts, manuals, etc. around in the trunk/back seat, so it's not as front heavy as most people assume. Even with all this weight, I still average over 22 mpg. It's been as low as 15 mpg with a heavy foot in the twisty stuff, and as high as 27 mpg on straight and level 2 lane roads - with a lot of cops around.
Thanks for taking the time to respond. It is appreciated. And although you've been here over 5 years, welcome to the US!
Nitto did have the nt450 in my size. V-rated like the ones I have, so I'll have 4 new ones soon.
Time will tell how they hold out. In So. Cal, I can't even be assured of a decent rainy season.
Enjoy the tires!
I had convinced myself to but the Potenza RE950s but could not pass up:
- $50 rebate from Sam's
- Motorola promotion from Michelin
- Sam's road hazard warranty included in $9 installation
So with the rebate, the installed total came to $330 + tax, not bad at all, especially considering the warranty is included.
By the way, Sam's does not stock that many styles and sizes of tires, but you can order pretty much anything from the manufacturers it carries.
And a great Flash intro on their website. I'd buy a set just for that!
I would take the tire to a Mich delaer in your area that has a good rep and have them inspect the tire and give you an answer.
I don't recommend this, however.
Then again, I'd take that over a "donut" spare any day of the week!
Thanks
YOKOHAMA:
205/55VR15 87V SL AVID-V4
or
195/55TR15 84T SL AVID-T4
or if someone has a better tire in mind, please advise.
Thanks!
Also check out the Michelin X-One and Goodyear Aquatread 3. Both have good reputations for 4 season performance.
Just an idea: it could be related to overloaded trunk.
The high weight of front hardly can contribute to hydroplaning. Just the opposite: the hydrodynamic lifting force (not sure I used the right English term) depends only on geometry and speed. If the weight is higher than the lifting force, the car will not hydroplaning, if less than will.
However, a load in trunk lifts the front. Possibly, it will be enough with already marginal road conditions: puddles and high speed.
By the way, even big cars often are not designed to high payload. I looked at manual for my Buick Regal, the section "loading". Turned to be, the maximal load permitted for the car, including driver, passengers and freight, is 420kg (925lb). Not so much. Even worse, only 75kg (165lb) can be put in trunk safely; additionally GM recommends to push the freight as deep into trunk as possibly, up to the back of rear seat.
Of course, your car is much bigger than the midsize Buick; however it not necessary translates in substantially higher load capacity. According to the following article in NY Times, Neon have total load capacity of 865 lbs, while Buick LeSabre 1075 lbs.

Thanks again for assistance.
You're welcome for the Yoko Avid Touring recommendation. For the price I think they're the best for my minivan. I thought about spending $25 more per tire and getting Aquatred 3's as they had a little better wet traction rating, but decided for that extra $100 (set of 4 tires) I probably would not notice the difference in the rain, and the Yoko's were rated better for comfort and noise, which I will notice every day I drive. Plus, I've had bad past experiances with Goodyear tires.
Tlindeman,
You're the first one I've heard who thought the Avid Tourings are noisy. On most the roads I drive I can't hear any tire/road noise. If the road is grooved in preparation for new asphalt or has rain grooves there is some noise, but not as much as I had with other tires.
Appreciate any feedback before a final decision
Although the Avid Touring are about mid-range (GOOD) in Snow rating, they rate even higher in all other categories.
My personal opinion is that with a CR-V four wheel drive, you don't have to worry as much about getting the highest rating on Snow performance. For the price and other high scores, you can't beat this tire.
I'm considering either Falken ZE 502 or Dunlop SP Sport A2 as replacements for OE Bridgestone RE 92.
Jim
Sorry I couldn't be more help. Oh BTW, the tires were on a Plymouth Acclaim Turbo so the tires should have outperformed the car, not my experience though.
I'm considering getting the Goodyear Aquatred 3's as replacements. I've been told what makes them such a good rain tire is exactly what should make them a bad tire in the snow. If anyone has had real-life experience with these in snow and on ice, I would appreciate reading your post.
Thanks,
Joe
Ask around. Look at other car's tires. How many Aquatread's do you see? Look at the GY Eagle Ultra-Grip and compare to the Aquatread's design.
On Tire Rack.com, the only tires that have better survey results in snow traction are the Michelin Symmetry and Bridgestone BT70s. And there aren't enough consumer responses yet to make a reasonable judgement.
Jim
Thanks

I have the Michelin Energy MXV4 Plus and think they are an excellent all-around tire. Somewhat sportier than the two mentioned above.
The Goodyear Aquatread 3 will be very good in 4 season weather and give long tread life. The Eagle LS gives a smooth, quiet ride at the expense of tread life.
I've heard good things about the Bridgestone BT70s but don't know for sure how quiet they are.
Mich- MXV4+ not that highly rated for snow traction at Tirerack.
Cont.- CH95 same rating as the Mich at Tirerack
Bridg.- Turanza Revo- Ok rating
Dunlop- Winter Sport M2- great rating but in their snow tire catagory
If anyone can give me some help I would greatly appreciate it!
Yes, tire design plays a big part in ride quality. But you have a performance sedan that has a stiffer than usual suspension. To get the most out of that car you need a performance-type tire. That was the RSA.
You could go to 215/60-16 or 225/60-16. That will give you a taller sidewall and more cushioning over bumps. But you will need to ask a pro if the taller tire will rub the fenderwells or strut tower.
The Michelin Energy MXV4 Plus is a more luxury-oriented tire and might do the job you need. The Bridgestone is a competitor. Can't tell you too much about the Conti.
Personally, I always feel it is a mistake to differ from the mfr's direction. If Nissan says "215/55-16" then that's the right choice. Maybe go a little wider but that's all.
The only tire I can think of that does what you want is the Michelin X-One. Closest size is 215/60-16.
Thanks much for your comments

Wal-Mart sells a brand called Douglas. Does anyone know if this name has a parent company? Are they considered good quality?
