We are running 11psi in the RR which shouldnt be in issue. I ran 9psi earlier this year without a problem but didnt feel safe and changed to 11. Since I got new tires and dimpled the the RR rim I havent had any issues and I really hammer on my RR.
As far as an update, Saturday went well at the WoO show, finished 2nd in my heat. In the feature started 3rd row outside and got into the lead on the 2nd lap and lead 10 or 11 laps before our 2 top masters caught and passed me. i was able to hang with them and on a late restart pulled along side of second place but he came up and I jumped his RR and lost a little momentum. Ended up 3rd, I am very happy with that being my highest finish at Charter.
