Following the manual, I have just tried two 215/40/17 tires on my stock WRX wheels. Turning lock to lock, the tires do not interfere with the angled frame but touch the vertical fire wall. I thought this size tire would work, and I am at a loss of what to do.
Fortunately, I did not purchase the tires. I am lucky enough to have found a tire dealer (Radial Tire in Silver Spring MD) who has lent me two front tires, one Fuzion ZRi and one Nitto Neo Gen to see if they fit. He also gave me two used 245/40/17s for the rear, which seem fine.
Any suggestions? I need to return the tires on Monday. (Please note a posted this information in a reply to an earlier thread on tires and am reposting with more information.
