On our way to Mega I put 42 front and rear in my Avons thinking that since I was loaded and runnin a lot of straights to get there it would help with wear.
Stretch did the same with his Pilot Roads.
As we started to get to some twisty stuff the bike felt very unstable, even my wife noticed it when we went over tar snakes and such. We were talking at a break and Strecth said his felt similar. So we both dropped air pressure by 2-3lbs and things felt back to normal for both of us.
I never thought I would be one to notice slight changes in air pressure but after that it made a believer out of me. I'll sacrifice some tire wear to have the feel in the tires.
