Hi fellas, I just bought new rear tires 3 months ago and they were great. Handling and balance were fine. Then, last week I pick up a nail in my driver side rear on the inner sidewall and so had to get a new tire again. In the 3 months, I only put on about a thousand miles so figured the difference in tread between the two tires would not be much. However, after the new tire was put on, when accelerating, I notice the car was a bit squirrelly so I couldn’t even fully accelerate for fear of the back coming around. Is this cause the one new tire needs to break in?

My guess is the slightly different diameters are throwing it off.

Mold release compound on the new tire needs time on the road to wear off. A few hundred miles has been suggested on this forum. Just a thought

Three months should not make a difference. Give it some time for the mold release to wear off completely. Verify tire pressures.

Thanks guys. I will wait a few hundred miles. The tire is exactly the same brand, model, and size as the other side so hopefully it settles.

Dammit. Beat me by a minute.

It's just the mold release. You'll be fine.

That and check the pressures

As noted, mold release likely. How many miles on the tires? You'll need 300-500 miles for them to settle.

Thanks…I have about 1000 miles on the tire on the opposing side and the new tire is brand new with no miles…now about 15 miles as I took it for a drive yesterday. I checked the tread depth of both with a penny and it looked virtually the same depth.

My experience is that you need ~100 miles on a tire to scrub off the mold release.

All tires need to wear-in to scrub off the mold release on them. New tires are slippery and need to be driven gently. You're really noticing it, of course, because your new, slippery, tire is sharing the load with a grippy tire.

Just go easy for a while

Thanks, will do! This is the dang nail that killed my almost new tire! Inside sidewall. Not sure how the heck that happened!

It has been my experience that rear tires suffer more nail punctures than the fronts. My guess is the fronts lift the nail off the ground enough thus increasing the odds of a penetration.
