Greetings! I just replaced my rear tires today, and now I have a pull to the left under acceleration.

I replaced the tires because they were at the wear bars, but the right did show more wear, especially on the inside, like i had a toe/camber problem.

After having the new tires installed, I noticed a pull to the left under acceleration that wasn't there with the old tires. It tracks straight under decel. Maybe the old tires were worn in such a way that it tracked normal all the time?

Is it possible that this is my alignment? I don't see how it could be, it seems that if it were, the car would pull to the left all the time, not just under acceleration.

Any help you guys can give me would be greatly appreciated, I'm really kinda stumped on this one... after searching, all i read is tired pressure. And I did check mine, cold pressure is 32 in both fronts, 34 in both rears.

Any ideas?

 

If the pull didn't start until the tires were replaced and the tire pressure is correct in both rear tires, you've got a tire causing the pull.

If the tire is not directional, swap them side to side to verify the pull moves with the tire. Directional tires can't be swapped sides to prove this.

 

They're directional., Toyo Proxes 4's. What should I do? Could the tires have different OD's even though they are the same size? Can I drive the car this way? I've already put 100 mi. on it since the tire change, and would have to drive that far to the shop again. I don't want to grenade my LSD for some damn tires.

 

HOW is it my diff? HOW would it be my differential after a tire change and not before?

Could you give me a way to test the fact that it's my diff. instead of just going, "oh, sorry, you're ####ed, now figure out why?"

I recently did an engine, transmission, and diff. fluid swap. I use RP 75-90 in the diff, and i used the proper amount of fluid. There were no unusual metal flakes or chips in the fluid.

I got this car from a guy that really took care of it, it only has 44,000. It is shipping to Germany in less than a week.

 

A stock diff isn't going to cause a pull.

See if you can swap wheels with a local to verify the pull moves.

 

There is a meet tomorrow night, maybe I can try there.

IF i can drive the car as-is?

 

You'll be able to drive the car, even if you have to counter steer.

Tires cause 90% of the pulls I deal with daily.

 

Okay... i feel a little better knowing that I'll be okay to drive the car, I'll trust all those little blue stars by your name. Tomorrow morning I'm going to check the OD's and Lot #'s of the tires and see if they are different. Now I just have to convince the shop to give me two new tires free of charge.

 

Why not just get an alignment?

 

I'm going to... I just pulled both tires and they have the same Lot #'s and OD's. I cold pressure and they're all the same after sitting overnight. I guess alignment is the next step... going to get that done today.
