When my bike was brand new I had Diablo Rossi 110/140s put on. Im going on almost 10,000 miles at this starting to show. I have heard of chicken strips but this seems kinda different.

Dayyyummm Jay hahahahahah

What psi you running those, looks a bit over inflated? I assume you rack up a lot of commute or straight line miles in Az? But hey... if you can get 10k out of the rosso's and your happy with the feel of the ride, then who am I to say nuttin'.

What exactly am I looking at?

Well what you got there are cords. Right behind those is air.

(p.s. it's time for new tires, about 500 miles ago)

I figured it was time for a new rear tire obviously. I was just wondering why this happened because my treads are still fine. Yeah I know for commuting Rosso's are overkill but the guy I bought it from was the one who put them on that's the only reason. PSI was at what the tire told me to put it at and I haven't added air since. But yeah I do a lot of straight line riding considering I only use my 250 for commuting but I will probably just replace it with a Rosso again because I like the bigger tire plus it'll match the front one.

It happened because you mostly ride on the center of the tire. So... it will naturally wear out faster. Us canyon carvers/track riders have the opposite problem, the sides where out before the middle. You can lower the pressure just a few lbs if you want and it will not "concentrate" the wear directly in the center. But then you will replace that with other issues; lower tire life and they will square off. :(

You're way past the treads in the center buddy. You have to check the treads where you're actually wearing away at the tire, not just at the edge. You can buy other tires in a 140.

Yep, that's what happened to my Rosso II's after about 6000 miles, though I foolishly had lower PSI that what the tire recommended so they wore out faster. Tire guy was impressed as it only took me two months to kill the rear tire and now the front is dead too after 12,000 miles. It's strictly because of long flat straight riding.

I'm tempted to stay with the Pirelli's due to the varied riding style that I have, but if the cost of replacing them for you gets to be too much i'd look into a tire that was designed for the long haul on flat roads.

I'm pretty impressed you got 10K out of them. I only got 7K out of a Shinko Podium rear.

...........PSI was at what the tire told me to put it at and I haven't added air since............

And how many PSI the tire told you to put?

Well it was my first motorcycle so I'd say the first 2k miles were noob miles going 10mph around my neighborhood HA. But I'll see what other brands I like in the 140 size. thanks guys.

I believe psi for the rear was between 38-40. It was pretty firm but not incredibly hard. Maybe it looks over inflated just because of the size of the tire? It just kinda looked bubbled over because it's a 140. Never had issues though, I did some curvey riding but mostly commuted.

The PSI on the tires is the max, not necessarily what you should be riding on. The bike manufacturer's recommendation is 28 front, 32 rear.

Sell those to rojoracing53 he might be able to get another 2k miles out of them, tread on the sides is still mint!

I believe psi for the rear was between 38-40.........

Rear pressure should be maintained close to 32 psi and front close to 28 psi.

It is better to check pressure once a week.

I'll give you $30 for that rear tire with untouched sides.

Yeah sides are mint. I'm waiting to hear back from my shop as to when I can come get this replaced. I usually do my own work but as far as tires go I don't like messing with that. But I don't mind selling you the rear

Of better yet ill just trade you this rear off my bike since the middle is still good.

I'll probably be going with a new one because now that the riding weather is going to be finally below 105 degrees I might actually go get to do some real riding up north in the mountains.

Rear pressure should be maintained close to 32 psi and front close to 28 psi.

That's the recommendation for the standard-issue bias-ply tires that come with the bike. Pirelli recommends a little higher for these much softer tires. There's no perfect answer, but I'd start a lot closer to 32f/36r and adjust to preference from there.

Will I notice improved riding with the psi being a bit lower? Not that I noticed anything wrong before, or is it just better for the tire.

Also I recommend plasti dipping the center of the tires. Probably get another 20k out of them.

Is it safe enough to at least ride my bike to the shop to get it replaced. I can take surface streets, probably about a 10min ride from my house

I could use some plasti dip on the tires just to get me to the shop if it's necessary

Just barely...

Yes
When my tire looked like that I was 80 miles from home and made it back just fine. Yes it could have blown out on me but it didn't and you'd be surprised on how thick the tire still is when you can see cords.

My bald front tire that still had great canyon traction.

Oh wow didn't realize how thick they were

Letting it get worn down to that amount of tread is just asking for trouble on the street IMO.

I not recommending riders let their tires get this low but I just saying that for street use I was still able to ride a my normal to fast pace on that tire with zero problems or loss of traction. A year ago I believed in the conventional wisdom that's passed around by word of mouth but in that last year I've learned a lot of it is way over exaggerated.

But please with a tire like this you are taking a risk that most riders aren't ready for should something go the wrong way so always play it safe.

Jason, yo man? Too many straight line miles on that tire. lol
