Just curious what tire pressures you guy's are running. *Spec is 36 front and 42 rear

List your weight, riding style and the tire pressure you run front and rear

I am 215 lbs ride fairly aggressively and have my tire pressures set at 32 front and 36 rear (right now)

 

i would just toss the factory specs out the door and go with the actual tire company's specs...

mine right now is at 36/35...mostly street right now...and some canyons...weight 175...gear...190...i ride aggressively period...but not like a ***** though...running diablos

 

can't go wrong with 35/35 ridin solo.

 

I run 36/36 on PP's

If you call your tire company try to get ahold of a RACING tire rep. The phone monkeys usually don't know crap about sport riding.

 

i always start with 36 and 38 because in two weeks i know i have lost a couple lb's anyway in the back forsure. but i weight 205 lb's.

 

hmm i run 32, everyone ive talked to said its the golden zone.
why idk, i havent even experimented with different pressures yet.

can someone explain specifically how will pressure effect handling, tire wear/heat cycling, traction on different surfaces ect.??

 

Yeah I'd be interested to hear about that too.

I know quite a bit about car tire pressures and what effect that has but not sure on bikes.

Somebody want to share there first hand knowledge/experience playing with tire pressures?

 

Generally lower pressures will lay a larger footprint and heat the tires quicker.

There are diminishing returns because if pressures go too low, the tire overheats gets greasy and wears fast.

High pressures give you less traction and a smaller footprint. If you run too high you will just eat the center out of the rear tire. (been there, done that)

You will want to run higher pressure when you carry a pillion becuase you are placing more of a load on the tire.

Pressure also effects suspension because tires act like an "air spring" but that is really outside the scope of this discussion.

You really should play with your pressures and see what you like. I know running higher pressure (40's) in the back made the bike feel less stable coming out of corners. 36/36 seems to be great for me on the street and seems to be a good all around pressure. I was less agressive in corner exits last year. I have a feeling if I raised my rear pressure to 40 this year I would be lighting the tire up on the exit. I get some spin now with 36psi in the rear.

I have been told for PP's 32/32 is the best for the track. This was supposed to have come from the Michelin man himself.

 

thanks blackdog, thats about what i was assuming.

 

30-36 and rear at 18 HAHAHHAHA sometimes 20-24
