Ever since I bought this 2000 Camry a couple of months ago it has slightly pulled to the left. I finally got around to switching the two front wheels. Now it pulls slightly to the right. So I know it's the tire.Good. Is this tire safe to use? O.K. for spare?
Oh,yeah. I checked em for that. I saw in some old posts I resaearched a month or so ago that this is something to do with the tires' belts or sidewalls or something.
Yes, if it is a belt seperation the tire could blow. Do a visual on both tires to see if there is a bulge, indentation or bubble on the tread area. It helps to jack car so wheel can spin freely. On the sidewall there will sometimes be a dip or indentation that is perpindicular to the rotation of the tire, this is ok, usually just indicates where the belts overlap under the outer layer, no bulge allowed on sidewall. While doing visual, look for any wires protruding through rubber, if none, carefully feel around tire to see if you can feel a bulge or indentation. If bulge or indentation in tread area then belts are seperating and dangerous, if bubble then tire is delaminating. Are tires the same size? Is the amount of tread close to the same (if there's a large difference in tread this can cause pull)? HTH, davidj92
What you want to do is run your hand over the tread, all the way around the tire. If you feel a lump in the tread somewhere, you have a broken belt and NEED to replace the tire! NOW!
Also, check the sidewalls for bulging. I am assuming, since you had the trie off the car, you probably didn't see any. But look anyway...
Are there any other 'symptoms'? Do you get a pulsating in the wheel at low speeds? Do you here a tuptuptuptuptup as you're going down the road?
The first is another sign of a broken belt, the tup noise is cupping. Broken belt, replace the tire NOW, cupping, replace the tire when you get around to it.
it is called "radial pull" I think. Not that uncommon tire manufacturing defect. Had the dealer replace a tire last time I bought a set, based on exactly your experience - if switching sides left to right on the front moves the pull, that confirms it. Has to do with "conicity" ie., the tire tread being conical instead of flat. Not a safety concern, just means one sidewall is slightly stiffer than the other so instead of rolling down the road straight ahead, it mimics the behaviour of a styrofoam coffee cup with angled sides, thus the tendency to "pull" at highway speeds.
If the tire might fail, putting it on the rear might not be the best idea. A blow out on the front can be bad, but one on the rear can be worse depending on when it occurs.
I've had tires that pulls after the first rotation for no apparent reason. I have guessed, assumed, hypothesized that this was because the tires internal construction took a set based on the direction of rotation and then after cross rotating, the set caused that tire to have a higher rolling resistance and this causes a pull. In my experience the cheaper the tire, the more likely this is to occur.
