have you guy's ever checked your warm tire temp? if so how many psi over your cold temp did you gain...and i'm talking about a few miles of easy riding ..not like kkim's commute:)

interesting... I've never checked my warm temps. What should you aim for when warm?

i allways see a 4-5 psi increase on my rear and a 2-4 psi in the front..but i have not been scientific about my checks. I'm sure the high end was after i'd been hitting some twisties and the low end warm after driving 8 miles or so to the nearest compressor

Between 29PSI and 31PSI in the front and between 34PSI and 35PSI in the back. The ambient outdoor temperature where I live in CA can vary by as much as 40 degrees going through different micro climates. So I don't have any really hard number that works everywhere.

Edit: those are warmed up tempatures.

thanks for the clarification. have you tried lower pressures? I have a hard time riding when the rear is above 32. Tire starts to skip at times and seems to loose traction, plus the bike just feels harsh. :(

I don't have any problem with the rear at 34-35. I think that's because I'm on the heavy side at 215 lbs in gear.

ok is that hot or cold..like if you hop on the bike and ride it a few miles is that when you get your readings..or is it in your driveway b4 you ride

ok i can't pay attention 35 psi warm..hhmmnnn.. i think the slip i've felt b4 is probably from getting my tires hot at a high psi..35+ ? I always thought i was hitting gravel or what not

We are supposed to check the tire pressure??????



lol I can't remember what I run mine at. I'll check that this week.

riding the 250 vs the 700 'ceptor, it seems that slight tire pressure changes are WAY more noticeable than i recall them being on the larger bike. maybe it's just me but....damm what difference just a few psi makes.

k den :ride:
