Tire squaring?  What's that?  Oh, right, I live in the mountains...  However, I run ST tires all the time and they serve we well, even on Deals Gap and such.  I'll get the occasional slide from the rear on heavy handed corner exits, but that's about it ~

Im not to judge but most people dont really go over the edge on the street whe nit comes to a sport tire.

I'm not to judge, but most people can't ride for shit.   :-*   Come check my tire, you'll find no chicken strips.

My friends all went out and bought Japanese 600 and 1000's and I took my time learning on a 250.

Try keeping up with sbk's on a 250 that tops out at 105, you will learn to ride well real quick. Having the 696 now, I have no problem hanging and when I lead, a few drop off.

I don't think just cuising down the highway wears the tire that much.  It's stopping, accelerating, and changing direction when the wear occurs, when the tire slides against the road.

You would think, but a few hundred miles on the center patch sure as shit wears it out.

Maybe so. Im just relaying my experience with the pr2.

Its not a bad tire. In fact it sticks so well in the rain you can ride in a really unlawful manner.

This is on a ktm 950smr. No burnouts. Lots of short wheelies and throttle on exit.

Im just not destined to get 8000+ out of a rear tire.

agree. the pilot road 2 gives me way more confidence in the rain than the BT016 that was stock

I would think raising it slightly to minimize the amount of tire that is subjected to squaring would be more ideal, but not sure either way

Yup.

When the tire carcass bends, it makes heat. More pressure = less bending = less heat in the rubber = "harder" rubber = less wear.

Decreasing the pressure would "weaken" the tire, resulting in more deformation at the contact patch and faster wear. Ever picked up a nail while riding? I have. When I rolled to a stop, I had a 6" wide section of Pilot Road rear tire that was essentially liquid because there was no air pressure keeping the tire round.

If you know you're going to be making a slab run, stop by a gas station and add a few PSI.

I can't wait until Marquez gets on his level and makes Jorge trip on his tampon string.

thanks for the confirmation - i had heard it somewhere and been employing that trick for awhile, but started to think i was imagining things

I would give the Pilot Road 2 a shot.  I've had them on my ZX-12 / ZRX / FJR / Sprint ST and they've been awesome.

Keep in mind - the "sport touring" compound of today has the same capabilities as a race level tire of a few generations ago... at least according to the guys at Cornerspeed.  You may just be surprised  [thumbsup]  I have seen guys on the track whip around on PR2's in the A group all day long without incident, for what its worth.

Take your cage for your long highway trip.  Who'd want to subject their bike to that kind of abuse, anyway?   ;D

Seriously, if you really want significantly higher mileage between changes you just get harder tires.

My preference is for Pilot Power or Pilot Pure, though I can barely tell the difference on the street.  I've also tried Pirelli Diablo Rosso and 2CT Michelin models with little variance, for what that's worth.  I though the Rossos were going to wear longer, but they really went off quickly at some point.  Oh well......

Sage advice from a guy who does well to get 2500 miles on a front and MAYBE 3k on a rear...so take it with a grain of salt.
Never appeal to a man's "better nature."  He may not have one.  Invoking his self-interest gives you more leverage.  R.A. Heinlein

I've gotten 7000 on a pilot race that i ran on the street after i felt it wasn't good enough fir the track anymore. I was pretty impressed with that.

I usually get 2x the mileage on fronts vs rears.
