  • Has anyone had any experience with the folks over at www.tirerack.com ? They seem to have a pretty slick web site with a good selection of products.
  • I've heard nothing but good things about them.
  • Recently, I purchased a 92 Q45 with new Viper Tires. First of all I have no idea who makes these tires. Does anyone else? Anyway, I have a front end vibration that is getting worse even after I had the car aligned and balanced. Now it slightly pulls to the right and the wheel wants to move off center slightly to the right as speed increases. There is also a jumpy type of feathering on the inside edge of the front driver side tire. Anyone have any idea? I think the tie rods and bearings are ok. Many have told me that my tires are bad and simply replacing them will correct the problem. I just don't want to jump and make the purchase when they may not be the problem. Please e-mail me with any info at [email protected]

    Does anyone know anything about the laser balancing?? My tire store use the conventional tire balancer, and it didn't balance my tires correctly for several times already. Someone suggested the laser balancing. What tire stores use it??
  • gusgus Posts: 254
    Call tire shops in your area and ask them. Why do you suspect that your tire balance is off? What problems are you having?
  • pomanpoman Posts: 46
    I got a new set of wheels for my Solara. I upgraded from the stock 205/60HR16 to 215/45ZR/17. The tires are not balanced becuz when I drive on the road the steering wheel and front wheels shake a bit at higher speed. I brought the car back for them to balance again, it was off. After balanced, still does that. So I called the tire company (Nitto) to see if they have any suggestions. They told me try to balance it with laser balancing. They said that some wheels are very difficult to balance correctly.

    20, 30 yrs ago the hot tip in tire/wheel balancing was to spin balance them on the car. Nowadays I'm unable to find anybody who does it.

    Has spin balancing on the car (which seemed like a heck of a good idea to me) been superceded by some superior method, or does nobody have the equipment or does nobody give a damn or do I just live too far from civilization?

    If somebody could explain laser balancing too, I'd be grateful.
  • pomanpoman Posts: 46
    Well they do spin balance but it's just not on the car. I believe this method is not accurate enough. They had the tire balanced by the spin balance machine the first time I got the tires and wheels. I saw the machine give a 0.0 0.0 read out myself. Then the second time I brought it back and it's off already. What's up with that?? I didn't change or touch the balance weights (it's a stick on weight in the inner sidewall of the rim.) What happened to make the balanced tire unbalance again??
  • C13C13 Posts: 390
    On the car is a whole different thing. Completely different equipment.

    It's a way of balancing the entire rotating mass: wheel, tire, brake disc, lugs, etc.

    I haven't seen it done in years.
  • guitarzanguitarzan OhioPosts: 817
    Poman, how many miles had you put on the car? The loss of rubber would be the most fundamental reason for the balance changing. I
    don't have knowledge of balancing, but think a shifted tire (a possible anomaly) could change the balance also.
  • pomanpoman Posts: 46
    That's a brand new set of tires and wheels. It has been about 1500 miles already. The steering wheel still shakes (well not exactly shakes, it moves left and right at a small distances (1/8") rapidly) lightly at high speed.
  • guitarzanguitarzan OhioPosts: 817
    First, I'd go with the manufacturer's recommendation, and try a wheel alignment shop with more advanced machinery. It would be comforting if you talked to a few places, and someone finally said, "Oh yea, that combination is trouble, but here are your options." (Key: some knowledge due to experience behind the response.)

    High speed shimmy might be caused by a worn out steering damper if your car uses one.

    Power assisted rack and Pinion steering can experience high speed flutter as a result of oscillations.

    Wheel and tire balance is quite dynamic. Sometimes, the weight has to be split equally on either side of the "light" spot.

    Also, if you're weighted only on the inside of the wheel, the tires are probably not fully balanced.

    Finally, aggressive driving demands that the tires be shaved -- rounded. Trueing shows up separations and can reveal a tire that cannot be dynamically balanced.

    Thanks ratch!
  • What affect/impact does one achieve in moving up one tire size: i.e. from 185/60HR14 to 195/60HR14?

    Will this affect ride, handling, gas mileage, etc.? Any insight would be helpful.

    Thanks.
  • KCRamKCRam Mt. Arlington NJPosts: 3,516
    kt,

    Your handling will improve very slightly from the wider footprint. You will suffer from a slightly-off speedometer/odometer because a 195/60 is a fraction taller than a 185/60. A 195/55 would be the same height.

    The other factors (mileage, etc.) will be insignificantly changed, because the tire isn't substantially different in size. Had you done a full "Plus 1" conversion - from a 185/60R14 to a 195/50R15, you would see more subtantial differences because the tire now has less sidewall, probably a harder rubber compound, and (likely) less tread depth.
  • I am going to replace all my 175/65 tires to 185/60--it's about time. Does anyone knows which brand/model should I choose from? I prefer all season and low tire noise
  • KCRamKCRam Mt. Arlington NJPosts: 3,516
    shcst,

    what kind of car do you have, and what kind of driving do you do?
  • kcram,
    I'm driving new G20. Well, I guess my driving style is not aggressive, but sometimes I would speed on highway--to shorten the trip. In the city, I don't slam hard on gas nor brake. So what you think which model should I consider?
  • kcram,
    Sorry about the previous message, that question was for my girlfriend!! She drives toyota corolla (98). Her driving is very conservative--slow.... So what do you recommand for her car?? thank you
  • KCRamKCRam Mt. Arlington NJPosts: 3,516
    shcst,

    if her driving is that conservative, you may not want to change tire sizes - the performance advantages of going to a wider, lower-aspect-ratio tire wil be completely lost on her car.

    For her kind of driving, I like the Michelin X-One - available in both 175/65 and 185/60 sizes. They have a lifetime warranty, and with rotation, would probably be the last set of tires you buy for her car.

    Check these two websites for info on the X-One:

  • I just bought a 99 Chrysler Concorde LX with Goodyear Eagle GA P225/160R16 tires. There is a lot of road noise and I'm wondering how much is related to the tires. I used Michelin tires before on a 92 Dodge Dynasty and 2 of the tires had over 60'000 miles on them with still some to go, with regular rotation & balancing.

    Any help relative to noise factors for various tire brands. Thanks
  • For what it's worth, here is how CR rated some "touring" tires with regads to noise (dry/wet):

    -Michelin MXV4 much better than avg/avg
    -Goodyear Eagle GT+4 much better than avg/avg
    -Pirelli P6000 much better than avg/avg
    -Dunlop D60 A2 with JLB better than avg/worsethan
    avg
    -Goodrich Touring T/A HR4 better than avg/avg
    -Yokohama Avid H4 much better than avg/worse than
    avg
    -Goodyear Eagle LS much better than avg/avg
    -Bridgestone Turanza H much better than avg/worse
    than avg
    -Firestone Firehawk Touring LH
    much better than avg/avg
    -Cooper Cobra GTH avg/worse than avg

    I don't know if this helps much or not. It's from the '99 Buyer's Guide.
  • what is the optium pressure for tires, like certain pressure below max. psi? Also, is the pressure varied by season?
  • C13C13 Posts: 390
    There's no such thing. There's an optimum pressure for a given car, a given loading and a given type of driving. Check your manual.

    shcst12,

    You can also check the sticker in the door jam..in some makes of cars it is on the middle console door between the seats, but on most models, it is in the jam. This will give you the stock tire size, speed rating and proper inflation

    i bought a new car two weeks ago and it seems to track to the left when i let go of the steering wheel-- it slowly veers left-- i took it in to the dealer and they adjusted air pressure-- and they switched the left front tire with the right front tire-- on the ride home it appeared to have solved the problem-- the car is going straight when i let go of the steering wheel (but i'm waiting for a non-windy day to be sure that indeed the problem is solved)-- my question is-- is this a viable solution? if so, why? should the tires be replaced?? thank you :)
  • gusgus Posts: 254
    It is a viable solution. If you had a problem with your steering rack, or your alignment, you'd retain that same pull to the left. If there were a problem with the tires, you'd have a pull to the right now, since the tires were switched side-to-side. What kind of car is it?
  • ral2167ral2167 ohioPosts: 767
    toyota solara-- firestone bridgestone tires
  • philipphilip Posts: 2
    hi i have a Geo 91 prism (manual Xmission) and recently , while turning, at high speed, the car seems to vibrate a lot and also the steering goes out of control also. All the tires are new Michelen with only 4k miles on them . Also the alignment is good ( as it always drive straight- even at high speed).
    Does any one know of the solution.?
