I know some of you get tired of hearing this but I was getting some instruction from Eric Foss at TWS a few years ago and he told me if I put on new RR's I would drop 2 seconds a lap. I did and he was right. He said he knew that was going to be the case because he had been with Tyler the day before and when Tyler put on sticker RR's he dropped two seconds per lap. The tires I took off were in the 14-16 heat cycle range. This is the only time I got lap times from old to new tires in the middle time of day on the same track. half an hour apart.
