Cresson is just about the only other track in Texas I look forward to going to based on what I've heard from a number of different people.

two of the guys in our group were running sub 50's gsxrr 1K's and they're tire were gone by 3 oclock.
the front was too low and since most of the right handers there are on the brakes pretty hard(specially T2),thats what i believe tore them.
T2 right hander?

That rear at 22 hot seems really low?


As for the label posted up about not putting warmers on a hot tire. I would love for John and Patrick to chime in on this. If you let them cool, you are putting more heat cycle in them? What do we do?

The part about wrapping the tire is when you're done riding for the day. Some folks wrap the tire with warmers after the day is over to let them cool very slowly which some believe makes the tire life longer.

Apparently, Michelin recommends letting the tire cool quickly when you're letting it cool.

What he said...

I've got the same shoes and didn't experience that type of wear... I was running 31 on the warmers (so 33-34 hot). The rears are 25ish on the warmers (27ish hot).

Some people and track maps consider 1 and 2 as just 1 turn.
From what I've seen/heard at least.
Michelin Power Race runs really low pressures in the rear. . .

That clears it up... I was quite confused there for a minute...

Here's some new stuff! The front tire was looking normal most of the day from what I can remember, but at the end of the day it was curved on the edge. . . Whats causing that? See pics. . .
I've got 2 days @ TWS (Texas World Speedway) on this Front Michelin Pilot Race Medium. . .

Both tires look like normal wear to me. Nothing unusual that jumps out at all.

The edge of the front is just because you haven't used that part of the tire- normal for TWS (Texas World Speedway) with it's fast corners.

Read the bottom of the sticker where it says the "new" PR 3-5 should run 22psi cold. That is a very old sticker/information. That was when the Pilots were new.
Not sure why folks rave about Cresson? That track is only semi fun in a very narrow temperature range, on one line. Get off that line at your own peril. I know a few guys who gave up their memberships due to track conditions. A one line track at best. New section has better grip, but not very safe run off. A good layout with poor mechanical grip, thus the extreme tire wear.

You seem to run pressures quite a bit lower. Pirellis (Spercorsa pro) would normally be 30psi front 28psi rear cold, with an aim to get them 36 and 36 hot (either warmers or off track). In the UK anyway.

I have heard of folks dropping them 5 psi cold for a 5 lap qualifying run. But thats about it, and they are shot after that.

I was talking to John at the tyre stand and he said Bridgestone were looking for 31 and 31 hot. Seems low to me, but his theory was tracks in the US were of poorer surface and bumpier and the tyre has to work harder to cope with that. Did look a little bumpy at TWS (Texas World Speedway).

Sportbike Track Gear has helpful info on the Michelin Tires.

Below quote is from: http://sportbiketrackgear2.homestead...tire_data.html
Quote:
POWER RACE & POWER RACE “PR”

Ok, this gets confusing so we’ll try and make it simple. Michelin makes two separate Power Race tire line ups. The Power Race and then the Power Race “PR” series. The “PR” series are made specifically for the North American market and feature more technologically advanced and different tread compounds and casing construction than “regular” Power Race. “PR” models are typically only available from authorized race tire distributors. Altogether, there are seven (7) different compounds. Standard Power Race: Fronts and rears in the following compounds: Soft, Medium-Soft and Medium. The front compounds are slightly softer than the rears. (Example: A Medium front/rear combo will have a front that is slightly softer than the rear even though they are both medium compounds.) To identify the compound look on the sidewall of the tire and the compound will be directly follow the words “Power Race”. We Stock: Front 110/70 soft, 120/60 soft, 120/70 soft(PR1), med-soft(PR2), medium. Rear 150/60 soft, 160/60 med-soft & medium, 180/55 soft(PR3) med-soft(PR4) medium, 190/55 med-soft & medium.

Power Race “PR” Series – We stock the PR1 and PR4 combo and were able to get a special very special deal on PR1 & PR4 combos. We also have some other PR series tires such as the PR2(med-soft) front, PRC (soft triangulated) front and PR5(medium) rear, but they are rather expensive. Track Notes: Are you are running an SV-650 or new Ninja 650 twin? The PR1 with a Power Race 160/60 medium makes a great track day and race combo. Got one of the hot 600 in-line fours? The PR1 and PR4 combo sets give BIG dollar race tire performance at a smoking good price. If you take your bike on the street occasionally, or want a little harder compound for those really hot summer days, we suggest the Power Race medium front and rear combo. You 1000cc riders have a couple of different choices… The PR1 or PR2 front is an excellent front choice combined with a PR4 or power race medium rear. If you have a 6-inch rear wheel or just like the profile, the Power Race 190/55 rear is a phenomenal rear tire and personal favorite of the authors. We offer the 190/55 in med-soft and medium, with the medium being the best choice for most riders and conditions. IMPORTANT SAFETY NOTE: The 180/55 and 190/55 Power Race & PR tires run 22 – 24 PSI. Do not run above or below this pressure! Power Race & PR fronts run 31-33 PSI.
