A tire sidewall cut (not SMB-related at all)
This is not at all an SMB question, but I'm asking it here because this is a site I implicitly trust to give me a "No B.S." opinion. It also may be of marginal interest to other members, too, as it is a tire question.
My wife was driving her BMW 3-series the other day and hit something sharp and pointy with the left rear tire. She was on her winter tires, with about 17.5K miles on them. I had to rescue her by bringing a 4-way wrench and one of her summer tire/wheels.
Got her home safely, and then tested the damaged tire. It has a cut just outside the tread area that lets out air almost as fast as my compressor could put air in it. I figure it's wasted, as I would assess it as a sidewall cut.
So here's the question: Do I have to buy 2 new tires to fix the one damaged tire, or can I just buy 1 replacement?
I figure the other three good tires have about 50% of their tread left. If I get just 1 new tire, is there going to excessive wear on the rear differential by having tires with a difference in circumference if I mount the mis-matched tires on the rear?
I was thinking of getting one new tire, and putting the new tire and one old tire on the front, I would keep the equally worn tires on the rear because the car is rear-wheel-drive.
