Title: Do Pirelli tires have a wear strip?
Post by: ejw24 on July 03, 2008, 06:00:50 PM
Cleaning the chain tonight I noticed a spot in the center of the tire where some white is starting to come through.  Please tell me it's a wear strip and not the cords!
Taking the bike in next Friday for it's 6k service so I will get a new tire but I have a 150+ mile ride to the dealer. Thanks!

White = Chords

They do have wear indicators... which you've probably obliterated.  Get thee a new tire

Here are two different areas of the Pirelli on the rear of my VFR after I got home from my last ride.  If they look like your tire, you probably are looking at cords.

Take it by truck, trailer, van...... begged, borrowed, rented, stolen.....whatever..... please don't ride 150 miles on a tire with cords showing.

That's what I'm thinking, while the tire doesn't look nearly as bad as the one in the picture I don't want to chance it.

Is there any shop at all local that can mount fresh rubber for you if the wheel is off the bike?  That would be better than a crash from a flat.   :-[

You're taking a big chance riding a motorcycle 150 miles with cords already showing.  If it fails, it's not going to lose air slowly, and if it fails when you're riding at pretty high speed you might not be able to maintain control before you can get the bike stopped.  So even if you don't crash, you'll still have to haul it the rest of the way in a truck, but it will be more expensive for you than if you were to haul it in a truck in the first place.

If it were me, I would put a new tire on first, using a local motorcycle shop to put the tire on the rim, then ride it for the service.

Thanks for the advice, I'm going to trailer it to Denver.  A new tire at a local shop isn't an option.....Aspen is limited for any motorcycle services.

Every pirelli I have ever owned matches the picture that was posted earlier. after the 3rd tire, I switched to Michelin.

With out a wear strip, what should be used for a "tripwire" for tire replacement?  My Diablo's look good so far I just want to be carefull.

Diablos have wear bars, I think all tires have to have them, by law.

They are noted, I believe by little pitchforks at the edge of the tread surface.

Wear bars look like the circled part of this tire.  You should have something similar on the Diablos.

Edit, there is little 'TWI' lettering right at the edge, and there's a shallow bar in one of the tread grooves, about an inch off of centerline.

Ah Ha! but my TWI is right next to a "pitchfork"  [laugh]
