I have a 330xi and my front passenger tire was slashed. Since my car is AWD, I was wondering if it would be alright to just replace that tire or if I should get two new tires for the front. I bought all new tires in late February of this year.
It probably will be ok. I had a tire failure on my '01 330xi when my snows were about 3/4 worn, replaced it with a new one and everything was ok.
The same make, model, and size should be just fine. If your ex is still ****ed off, let's hope it's the other side that gets slashed next time ...
Personally, I would get two new front tires, because now you're gonna have a messed up tire wear schedule.
