I have no idea how old these slicks are they are Firestone's the have been in my garage for the last 4-5 years the tread looks nice the sidewalls look good would you gamble a few shakedown runs on them or not.
I know I need new tires but it should be running this weekend just thinking about getting a couple passes on them but?
