A40S tire sealing up on yellow
back in mods since July after 15 year lay off. was reading here about the A40S tire problem last spring but we haven't had a problem at all until last Saturday night. On wet track the tires will last several weeks and on dry slick track wear is very quick and tire feathers off but have had no problem with it not wanting to get forward or side bite after yellow flag conditions. But this week the track was dry slick during warmups so the track watered the surface of the track to keep dust down but not enough to give us mud to race on. With that extra moisture on top of track the tires were chunking out where the feathering normally has been taking place on edge of all treads. Running in 3rd place right with leaders for first five laps of feature until yellow came out on lap 5. On restart tires seemed to be sealed over and lost forward and side bite. What is proper procedure during yellow flag conditions to keep the A40S tires from sealing up on us?????
