How to measure tread depth on R-Comps

I'm new to R-Comps and this it probably a stupid question...so do I just stick a tread depth gauge in the little notch circled in red?

Yes, but a more important measurement will be heat cycles. I doubt you will ware them out, but you can expect adhesion to slowly go away, with more laps required to get the tires to stick. I get three to four (2 day) HPDE events on my BFG R1 compounds. After that, they become toast. If I was racing, only two events. My friend, who drives a GTR, puts new tires on for each event, but then again, he has lots of $$$peed.

If the tires retain their adhesion and arent heat cycled out (you'll feel the difference when they are done), right after the tires are worn to the point those slots/circles are gone (eg you dont need a tread gauge, those slots are your tread gauge), you'll cord the tire. First you'll see grey nylon and then the steel cords. Depends how rough the pavement is at your track. At some tracks I've corded them before they heat sycled out and on others, I've had 1/2 tread left but the tires became slick and lost their grip (heat cycled out).

You should mainly keep an eye on the tread depth indicators on the tires. If you're tracking your DD, don't worry too much about heat cycles, save some cash, and just have fun with the day.
