tire pressure

i know I am going to get alot of different answers out of this but what hot tire pressure does everyone run. This was my first time running track tires, I think that was one of my problems yesterday in turn 10. I lowered my pressure after my first session and could not figure out why the rest of the day I felt like in turn 10. I think I was runnin to low of pressure and the lower speed of 10 was making it hard for me to get the bike over.

Different brand of tires, require different pressures.

What tires do you run?

What tires are you running / what pressures were they at?
Has your suspension been set up?
What line were you taking the 10?

More importantly, do the tire mfgs. have their recommended pressures on the web?

The 28 psi hot pressure is pretty close I prefer 29 psi hot, on the BT002 Pro. 34 psi is WAY too high. The Pilot power front is a pretty triangular tire, the Bridgestone is more rounded and at the slower speeds you may be having a conflict between the two profiles. Different PR series fronts have different shapes so it is really hard to say.

Your Bridgestone rear pressure was good (29 hot), but your front pressure was too high for Michelins.

I can't remember, but were the tires take offs or did you buy them new? I'm guessing take offs since they're different manufacturers.

Tire age could have a lot to do with it, so does suspension. Personally, I don't mix and match brands, so I can't help you there, but it could be contributing too.

Next time, you need to try using the same brand of tire front and rear, it would make it easier to work with

Turn 10 is the only turn I was having any problems in. I kind of liked the triangular front made the bike dive in. When my 650 gets finished I will be runnin the 002rs front and the 016 rear.

Typically when your having a problem in one corner, it is the rider. Unless the tires are really wore out on one side and not the other, the bike should handle the same right or left. Riders usually have a direction that they prefer or feel more comfortable in.

Either way you should really like the 650 with those tires on there.

Good call

Get a single manufacturer tire on that bike, then, we've got other things to work on regarding cornering...

My bud Charles stepped up to run slicks on his SV at TWS (Texas World Speedway), and his first comment to me was, "why the didn't you have me run these before? These things are incredible!" He switched from the Bridgestone 090 to the Bridgestone GP250 slicks. I think he found Nirvana.

Brandon Spradling was running 003PROs on the front with the 016 rear, and he was absolutely raving about how good they were on the SV.

I can see you sticking with the 003RS front if you're not using warmers though.

I think I am going to order my warmers tomorrow. And speaking of working on corners you were suppose to help me, then decided you wanted to go fast.

Well, I do have priorities... I'll promise to work with you next time out, and I won't be bedazzled by Italian shiny objects!

I just wanna go fast!

Regarding the 003RS, I think MacMan was running those- at least that's what he said. Maybe he meant 002RS. John will know for sure (or Patrick), hit one of them up, but I was pretty sure MacMan said he had 003RS on his bike.

At the track? no. Listen to the tire expert posts above (John and Patrick). Those pressures may be fine for the street though.

I run about 55psi on the street and don't wear a helmet... less rolling resistance and less aerodynamic drag helps me get around 610 faster!
