It seems most auto manufacturers recommend replacing tires in pairs for 2wd vehicles and all 4 for those with AWD. I understand the AWD recommendation, but the 2wd puzzles me.
Is the 2wd a theoretical safety issue or is it based on a concern that different diameters of tires on the driven wheels will create additional wear on mechanical parts?
I just had an unrepairable flat on my 2012 Focus. The OEM tires have about 7/32nds of tread remaining (compared to 10/32 new) and the dealer is suggesting getting 2 new tires. Given this small difference, my instincts are to get a single replacement and bias the tire rotation pattern to leave It on the front until overall tread wear is evened-out. Thoughts? Thanks!
