3 tires in 5100 miles. I have just around that on my original set and i am just about to get my first new tire. It must be that yours is a 12 and mine is a 9. You are really eating up those tires. I thought i drove mine hard but you must be really rippin it up

3 reartires in 5100 miles? Damn dude! I have over 4000 miles now on my reartire that came with the bike when I got it, and the tire wasnt even new at the time. I ride a 12 as well. You must really launch that thing from a stop. 32 psi is also probably not helping by heating the tire up more. Run alot of twisties? Ive been running my rear psi at around 35.

Conti says to run the tire at 42psi, the bike is to light for this. Buell recommends front/rear 36/38, I felt the bike was to light for the 36/38, so I have mine at 34/36 and seems fine.

Can too much psi cause a tire to slip in a corner? I've experienced this a couple times in mid-corner on the rear. I never thought to check the pressure. I had a new rear tire put on a few weeks ago. Maybe they over inflated it? I need to check that pressure.

"Can too much psi cause a tire to slip in a corner?"

Yes. Too much tire pressure won't allow your tires to form the proper contact patch at lean angles, and will prevent proper warm-up for "spirited riding".

Changes in shape generate heat, and increase tire wear but going with the pressures in your manual should be the perfect balance of traction and tire life.

If you are still using the original front tire...
Mismatched tires can do all sorts of unpleasant things with regards to handling/stability, some mismatched tires work better together then others.
I still highly discourage it.

Keep using the same tire until you need to replace the set...

Fortunately I wear down the front as fast as the rear, so I just get a new set every time.

rednismo, you are definatley running your tires to low. After much research I have discovered that the tire should be kept 2-3 lbs from it's max pressure. this will give you the desired conformity to the road surface and give you the best longevity your looking for. I've tried if and so have many others it's the best way . I run mine right at 39-40

I know some of the Conti tires are spected to run 42 PSI In the rear tire.

Might I suggest trying 35 front 36 rear. Also might recheck balance.


And yes rake can play a role in how a bike handles. You can have increased rake but the suspension has to be at the right settings. The amount of rake increase from the tire change would not likely cause this effect. There is a handy troubling shooting chart for suspensinon/handling issues in the book "Total Control" by Lee Parks

btw there is a small suspension/handling troubleshooting guide in the Buell service manual.

I'm no expert on the subject, but every manufacturer I've dealt with has the suggested psi in the manual- regardless of tire brand. The tire manufacturer lists the tire's max psi, but that has nothing to do with how it will perform on your bike. Your bike was designed (suspension/weight/wheelbase etc...) to perform with tires at specific pressures front and rear. Those specs should not change even when using different brand tires.

I have the Pirelli Diablo T in the front and a Diablo Strata in the rear. They are separated by about 1000 miles of tread wear, with a psi split of 34/36.
I never had slippage issues before my tire swap. Now I feel like I'm babying the bike around a corner, and it sucks.
Next time, both tires get replaced together.
