Strange issues with new tires, nobody knows what’s wrong
Hey everyone.
A month ago now my car was driving perfectly, zero issues (2016 Scion FRS, manual 58k miles) I hit a nail in the sidewall and had to replace the tire. From that moment the issues began and persist now.
At first the car was unsafe to drive really at all because it was pulling badly left and right, couldn’t take it above 35mph because the pull was so bad.
First step replace the other rear drive tire; now I have two new tires both on the drive end. Same issue. So I replace the remaining two tires, now all of the tires are new (checked that sizes match the door sticker, rear brand is Falken front is sumitomo) Shop says my front struts and rear CV axel are shot, get a second opinion and they say they’re completely fine. (Which makes sense because the car WAS fine)
Get an alignment, issue improves slightly but still pretty bad. Get the tires rotated, then rotated again, then rebalanced. Get a second alignment, find out the first alignment wasn’t done correctly but now it should be fine. The issue is better and car is stable up until 85mph, then the wobble returns.
I’m just not sure what else it could be, at this point I have four new tires with matching PSI and two alignments, balance checks, direction on the tires checks out. What could be causing my car to wobble like this?
