Tracked my car for the 1st time yesterday!! Had a great time, except that at one point managed to put a flat spot on a a front tire. So I need a replacement. My current tires are only a couple of years old. They were about the last CR28 Size: 220/55VR390s before AVON stopped production. I'm hoping someone knows of a stray tire that's less than 5 years old & has plenty of tread. The other 3 tires still have plenty of tread. I don't really want to have to buy a pair of Michelin TRX's & run miss-matched front-rears. I'm saving to buy 16" wheels, but have other maintenance expenses planned & badly need these CR28s to last 3 more years. Unless someone knows of a set of 16" wheels I can get for less than $1k. Would be willing to repair curb rash, but can't be bent.
