Hello all,

So I have a 2002 XK8, last year I put on new tire front and back. A few weeks ago I ran over something and it cut one of the rear tires. I was able to order a new one, same brand same model. But my question is, my "old" tires have around 4k miles on them. Will this matter on the rear of these cars? I know if it was AWD it matters.

 

It would only matter if you were racing and pushing the car to the limit.

When you go around a bend the tyres rotate at different speeds anyway ..that what the diff is for so half a mm worn off one tyre will make no difference

 

Right and that's what I thought as well but others say yes that's true but that is not for a long time, not long enough to build up heat but driving all the time will..I think it will be fine tho.

 

The heating up of one tire more than the other due to a small tread dept is all theory and not demonstrated in actual practice, excluding racing of course.

I have pressure and temperature gauges on all four tires, At various times in my ownership I’ve had the need changed a single tire due to punctured, and also just change two tires due to wear, besides the usual changing all four at the same time At no time did the tire temperatures vary by even one degree, even after driving for hours.


However, when the car was stationary and the sun was hot, the tire side in the sun was showing higher tire temperatures until I drove for a bit and all sides started getting equal sun and equal road friction heat..

Most tire monitoring systems are pretty accurate. If I spin the rear tires they will show a brief temperature rise vs the front tires. Etc.

good to know, thank you

 

Never had a single tire replacement impede any of our vehicles' performance in any way. I agree that you will be good to go just replacing the one tire....

 

Where did all this techno crap come from? One tyre heating because is more worn than the other ..what a load of ball$$ .Just drive the thing and relax.

 

from the all-knowing internet, of course.
