I'm ready to replace my fronts for the first time since I've bought my car. I'm planning to get the OEM 16" Yokohamas. The inner edge of my current ones are smooth, I think they've been smooth for the past couple weeks. How long can I safely drive my car like this? I reduced the tire pressure on the front tires to about 29 lbs to hopefully even out the wear. I havn't been driving the car very hard lately, but I did take it on Laguna Seca once in December. What is the procedure most of you take when replacing your tires? I found the tires for $190 each at tirerack.com, but that won't include installation fees etc probably. I might go to Don in Daly City and ask him if he can do them. Andrie, if you're out there, how do you usually do it?
