I'm running cold pressure 40 front just shy of 42 in back and felt some tire slide on a few occasions. I ride a lot of freeway but do hit twisties fairly frequently. I got the standard tire that came on the 08 modles. Should I turn my pressure down or what? I know lefox you asked me about my tire pressure in the suspension topic and I though they were fine but after a bit more riding and reading I thought I would ask. Damn that sly fox

I run 36 front 38 rear no problems. I also ride a passenger alot. 40/42 is probably a bit heavy. Try knocking it down just a tad, should give you better grip cornering.

well I dropped it down a bit and went for a ride and those chicken strips are down to a 1/8 to 1/4 inch and the run corners don't seem as unnerving!! Now if I can get use to taking those steeper down hill turns eeep!! Thanks dozer oh and my arms dead now seems to take more pressure on the bars but its a good trade off!

all depends on the climate you are in...if you tell me what's yours, i can inform you better. streetuse, warm climate: f = 33psi / r = 34psi streetuse, cool climate: f = 36psi / r = 37psi Quoting burnteyes well I dropped it down a bit and went for a ride and those chicken strips are down to a 1/8 to 1/4 inch and the run corners don't seem as unnerving!! what are chicken strips?

you know you eat them! The ring on the edge of the tire from turning. Like where there is still new tire because you dont take turns fast enough to lean the bike that far over so that part of the tire doesn't get used. 33 psi ok for doubling?

you don't always have to go fast to hit the 'where the chicken-strip used to be area' it's all in the acceleration in the corner, not the speed. that is why buell is a fun cornering machine, because of the low-end torque which is good for the corner acceleration Quoting burnteyes 33 psi ok for doubling? dunno what you mean here

Inflate your tires with nitrogen, they last a little longer and hold pressure for a longer period of time.

Hey on the nitrogen note, be careful, some places will try to rape you on nitrogen, All it does is slows the ability of your tires to lose air pressure (ALL TIRES LOSE AIR PRESSURE GIVEN ENOUGH TIME!). But BPG is right, I run nitrogen in my old truck helps for when I'm going off roading, every molecule counts right.

I set them at 34f 35.5r and rode with my woman and it done ok but rode surface was smooth but if we ride its only for 10-15mins because she cries that her big butt hurts. But I'll go for a ride solo and see if I like that or the 36f 38r better. I'm just worried about the ttire getting to hot and losing lifetime and getting to soft and having negative effects on handling.

Quoting HOVERJOCKI Does it also depend on the tire brand... running 2CTs at the mo... got 36 front/rear but heard about knocking it down to 30/32 Riding in hell here (Vegas 107 at the mo) if the ride is short to medium, would keep it at 33. but when the ride is long enough to get the tires nice and warm, go to 32. keep the front round 32, unless you feel that it loss grip. also, in that weather, there really no need to get a 2ct. you will be good with normal pilot powers, since warming them should be a breeze.

Thanks LeFox. You would have thought that about the temps but the roads here suck... they get so hot they actually slide under your feet.... alot of people who ride here have the 2CTs just for that stickiness. Gonna play around with the pressures over the next month or two and see what happens. Cheers

Quoting HOVERJOCKI You would have thought that about the temps but the roads here suck... they get so hot they actually slide under your feet.... alot of people who ride here have the 2CTs just for that stickiness. well, a tire is has almost the same effect. when hot enough, they will be too soft to maintain their grip. i don't know how you ride or if they are hot enough to get into that state. you are experiencing the heat and riding the bike, so you would know...but if you haven't tried it yet, i would suggest you do, since it will save you some money.

How much does the pressure go up once they get heated up? I checked mine after it sat for about 15minutes and they were 43f/46/rear.
