New to scrub slicks here. What criteria do you use when evaluating the condition of your new to you tires? What sort of problems should I be on the lookout for?

age is a concern, but I've personally never had a problem, and only know of a few firsthand issues with running scrubs. I'd avoid on banks/rovals, but otherwise if they aren't too old and show good life on the wear indicators, you should be fine.

One thing I always recommend to customers running used slicks is not to do the traditional mounting and balancing.

A lot of times scrubs have a bunch of rubber build up (track turds) covering the outside of the tire, if you balance with that stuff on and it gets thrown off after the first couple of laps then the balance of the tire is off.

Instead I would recommend balancing your wheels alone, then mount the tires. This way at least the wheel is balanced and when the turds get thrown off you won't have an issue.

Age and don't balance, I agree completely...and don't buy them in the winter if either you or the supplier live in a place where it gets substantially below freezing.

Some DE orgs will not let you run anything over 5 years old, and they do check.

I balanced my wheels when I get them, and taped the weights. Clean garbage off the wheels. Then absolutely never balance scrubs with all the tire snots, gravel, and other crap that hot tires pick up. I have never had any detectable vibration issues***, on the track. We are always changing speed, so there is limited opportunity for a resonance to set up in the suspension.

*** except when a tire(s) was flat spotted.

Do you say this because of the inherent dangers of banked corners and the unknown grip level of a used slick, or something specifically to do with slicks vs. banked surfaces?
