>Because you have a 3/4 ton it should have come with I rated tires. I rated tires support more weight than a I or I rated tire. < Huh? The highest load rating in a LT tire they make is an E, 10 ply. Did you run Edmund's funky spell check on this?
>I put Michelin LTX 275 70 HR 16. The are HR rated for speed 114 MPH and A rated for heat< Michelin doesn't show any LTX in that size. A 75 series, yes, but not a 70 series, and it's an E load rating.
My YXL is a 2001, 2500, 2WD with the new 6.0 I engine and 3.73 gears. It still has less than 500 miles on it, so I can't accurately assess it's true performance and gas mileage. I can say to all who are considering a similarly equipped model that I absolutely love everything about this vehicle, except for the undersized tires that came with it.
The 3/4 ton suspension is very smooth and I like it better than the 1/2 Ton. The 6.0L engine is also very smooth, responsive and has alot of power. The 3.73 gears are excellent on the highway and the torque around town is perfect.
I still have alot of tire questions. The door jam specifies a 255 / 70 / 16 tire. But the YXL came with 245's. So, is the speedometer calibrated for a 245 or 255 Tire? I haven't seen any 255 size tires on any YXL's or Subs.
Since, The Michelin LTX - M/S is a Mud and Snow Tire - Is this tire quiet enough for highway and road driving in dry conditions on goad roads? Does anyone know anything about the LTX - A/S tire? Do 265's rub with the stock wheel?
It seems that the GMC Dealership and tire store employees do not know enough about which tires are best suited for this vehicle. So, hope that some of you will continue to share your thoughts and experiences about your tire choices with the rest of us who need to know more.

On auto ride..everyone I have heard has said it is well worth it in every aspect.
You might look at bigger dealer with more volume in sales if you get tired of waiting. The more you pay or go with bigger dealer it seems the faster you get your vehicle. Good luck.
IMO, the Michelin LTX M+S is the best all-weather SUV *road* tire made, period; extremely quiet, great handling, and tremendous wear provided you ROTATE! The AT has a slightly more aggressive tread, as does the brand new "SUV" tire; better off road, but a tad noisier. Unfortunately, the "SUV" only comes in the P series, not the LT.
For a large truck, like a Yukon/YukonXL, putting on a P (as in Passenger car) series tire is the WRONG thing to do. The factories do this for insurance and cost cutting reasons, not because it is the most appropriate tire. P series are 4 ply tires, whereas LT (as in Light Truck) start out as 6 ply and go up from there; they are otherwise identical. There is a BIG difference in handling, not to mention load capability and resistance to sidewall cut. Additionally, there is no loss of comfort unless you go up to the E, 10 ply.
My $0.02 worth.

I highly recommend the Michelin LTX A/T (all-terrain), although I guess that would be a strange choice for a 2WD paved road vehicle.
However, you will probably notice the power loss on your 6.0L/3.73. It is not as noticeable on 8.1L/4.10. On either vehicle, the effective tow rating will decrease (although perhaps not on the 8.1L/4.10, since the 12000 lb rating is determined by the hitch capacity, not necessarily the drivetrain).
I don't know why your sub says 255/70R16 on the door jamb (my 2001 says 245/75R16). In any case, these are little tires (slightly wider, but shorter than the LT245's). Maybe GM is going to switch to using these shorter tires for 2wd applications soon? They already use 265/70R16 for 1/2 tons - approx same height but wider than the 245/75R16.
BFGoodrich - We Don't Sell Tires
We sold the tire business in 1986!. The BFGoodrich Company has not made or sold tires in more than a decade. This business was sold to Michelin, which continues to sell tires under the BFGoodrich brand. For more information, select the link below.bfgoodrichtires.com.
Seems when you buy BF Goodrich's, they're made by Michelin.

I did a little research on lemon laws and it seems to be a gray area as to whether we'd be covered under Florida or SC law. If you're really concerned you might want to call the Attorney's general office in each state.
We picked up the Suburban in early November and now have about 3,000 miles on it. Not a bit of trouble! Only hassle was trying to break it in right on the drive back. It's really hard to stay between 50 and 60 on I-95
Also scan this site I`m sure they have items to be considered when selling. A second source would be Cliffords site @ gmsuv.
The LT285/75/R16 tire fit the stock rims fine.
I had the cheap Fstones (AT's) for 10K miles. The new tires make a huge difference i cant believe it. Only downside is road noise. More aggressive tread and larger tire = road noise
BEAWARE also only way to reprogram your speedo is by buying an aftermarket programmer like a hypertech ($300) gm wont recalibrate for tire sizes other than what they offer GRRRRRRRRR. Cost me $20 from the dealership to find that out.
Also i have fender flares and mudflaps on my truck and no rubbing whatsoever.

Also, someone else was researching the maximum wattage bulb that could be installed in the factory fog lights. Any luck (or recommendations) on this?
Thanks...
You can change to bulb # 885 which is exactly the same except it is 50 watts.
On my 2001 Yukon Xl, i replaced the 3rd row light by a 2nd row light that have the reading lights in it.
The wiring is already there in the 3rd row light to plug it.
You just have to trim the headliner a little bit to make it fit.
If you need more infos, E-mail me.
luc,
Frankly though, I wouldn't recommend putting a passenger car, B load rating, 4 ply tire on any SUV, unless it was, say, a RAV4. To put those on a big SUV that's going to used to haul a lot of people and stuff is, in my opinion, simply not wise. But, that's just my opinion.
Remove your 2nd row light and you will see how it is mounted.
you have a little gap about 1/16 wide to put a screwdriver between the plastic lens and the base.
pull the lens down and you are done.
the 2nd row light has a plug with 3 wires and the 3rd row light has a plug with only 2 wires but the wiring coming from the headliner already has the correct 3 wires plug.
Cost of the lamp is $34.25 full retail but I only paid $25,69.

I was at large dealership today trying to put together the price of my trade and the cost of a new YXL. I asked the sales guy about the tires and he indicated the dealership got a memo that basically said the recall had been expanded to include additional models of the Firestone tires but he didn't know if tires on the YXL's on his lot were included under the recall and from there, brushed off the issue.

The dimmer resistor is in series with the I.P. lights.The dimmer you make the Instrument Panel Lights the more wattage you drop across the dimmer switch - making it hotter. Reducing the amount of dimming reduces the heat.
Until they redesign the dimmer circuit you have to put up with a hot dimmer switch area. It is normal.
Please advise if your I.P. lights come on with the Daytime Run Lights. I don`t. think they do.
Anybody else care to comment on mileage for 6.0 Liter engine?
Mike/DFW
You are right about the IP lights and the headlights. I haven't asked the dealer about a TSB yet,
but I will. Thanks for the reply.
Does anyone know what tires are now shipping on the new YXL. 2500. I do not like the Firestone
Steeltex 245s. Bummer!!!

Mileage on 01 YXL. 2500 with 6.0 and 4.01 is around 10 in town and 13 to 14 highway. I had
thought it would be higher.
Firestone Wilderness " tires. What is the best way to get them replaced? Do I write
a letter and complain that they thump? Is there a TSB out there or a recall? I'm not
sure what my next step should be.

Thanks to those who commented on mileage. For don4341, 10 in town and 13/14 on the road is pretty much in line. I had a Chevy Van 3/4 ton, 5.7L (350 cu in) with 3:42 rear end. It got 11 in town and 14.5 to 15 on the road. I'm hoping mileage will go up maybe 1/2 mpg by 5000 miles or so.
Don't get me wrong. I love my YXL. I have yet to find anything wrong after having it 6 weeks and am truly impressed with engine, performance, interior, and the list goes on................ and besides, IT'S A TANK!
horsepower and torque curve graphs for these engines? GM used to put them in the brochures
for Suburbans. Now all they give is the
rpm at which the the maximum for each is developed. I would
like to see how flat - or steep - each curve is. Also, does anyone know why the autoride package is required with the 8.1litre? I don't have a problem with the requirement - would probably order it any way. I have had 2 3/4 4x4 Subs;
a 1978 and a 1991(which I am in the process of trading for a 2001), both of which I ordered new. I am having a tough time deciding whether to go for the 8.1 or the 6.0 engine. I don't plan to do much towing, so that's not the issue, I just don't want to pay a big penalty in the fuel mileage department to have the extra power. I plan to get it with the 3.73 gears. Any comments or info on the relative merits of these 2 engines will be appreciated.
