tell us more about this tire issue[/QUOTE]
Third heat cycle, starting pressure of 13lbs. JP spun and I was in 3rd 14 seconds ahead on lap 17 of 20. LF went severely out of balance and I could see it out of round. It got worse on the right turns so I backed off and limped it the final 3 laps. JP passed me, costing me the podium.
It had a severe bubble about 4 inches wide. GY dismounted and I could see a 4 inch sawtooth separation of the threads on the inside of the tire. GY states that the minimum starting pressure is 15lbs. Steve Petrescu said that he asked Jon Lewis to notify all F1KCS teams of the minimum, but I never received the memo. I ran 8 races at less than the minimum and only now experienced this issue. Steve also said that GY will be changing the construction of the tire to account for it, but did not commit to a date.
