Default Road America tire wear- Cup 2s

First time at RA coming up and a question for wear on a 992 TT

Current Cup 2s have seen 5 track days and I have 2 days planned at RA next week. Home track is notoriously hard on the left sides.

My question is how do tires wear at RA? Is it worth swapping sides? My current tread depth on my rears is

drivers rear 5.5/32 outside, 6/32 middle, 5/32 inside

passenger rear 5/32 out, 7/32 middle, 4/32 inside

thanks in advance

drivers side

According to those measures, that’s pretty good wear! And plenty left.

The new surface at RA seems pretty "normal" on wear - I was there for 2 days over Memorial day and did not see any greater wear than before the repave on my Bridgestone RE-71RS.

Watch your heat cycles. Cup 2s have a tendency to only last about 20 - 25 regardless of tread depth.

The new surface is much less abrasive. One interesting byproduct is how little rubber is thrown off the tires - - the front end of my car had barely any rubber impacts.

I am on track Monday after Indy weekend. I’m sure I’ll have some major cleanup.

thanks for the replies

For me personally, the cup 2 would cycle out after ~6 days. Plenty of tread left any time I was "done" with them - so like someone else said keep an eye on the grip levels. You'll be fine with 7 days just dont expect any pb's

Be aware when a tire becomes “heat cycled out,” that generally the way to tell this is that the BALANCE of the car changes, ONE end of the car becomes more unresponsive (understeer) or slidey (oversteer) CONSISTENTLY.

If the tires are overheated, the loss of grip is global and relatively equal.
