hi chris,
You must consider that your tyres will get worked much, much harder than they ever would on the road and basically you can expect the pressures to rise by around 4-5 psi in the front and more in the rear, thus why we suggest you lower them. don't do ths till you get to school though as these pressures are to low for the road, We have prssure gauges and compressor to do this at the track.. Will it damage your tyres, nope, not at all, its the extra work and loads you put on them that destorys them. you won't destory a set of tyres in 1 day either!
Any other questions, please do ask, if not, see ya Monday.
Bullet
Thanks for clarifying the question Bullet. Looks like we should have decent weather. See ya tomorrow!
Chris.
