I put a set of Pirelli Angel GTs on my 1125cr about 3k miles ago. The rear is down to the wear bars all over.

Admittedly, I do crank it out of just about every corner, so I'm not too surprised, but the Angel GT was supposed to be a fairly long-lived tire.

What do you guys use? And how many miles do you get out of them?

I have fallen in love with the Dunlop Q3+ and the "regular" Q3 prior to that latest iteration. Although I must admit, I don't keep track of the mileage I get out of them as it doesn't matter to me. Also the fact my riding consists exclusively on shorter weekend foothill rides, means I never square off a tire these days. I will show cord in the area of the tire about halfway between the center and shoulder of the tire as there's nothing sweeeter than driving hard off the corners on a tractable, high HP V-twin motorcycle.

I am only concerned about performance, predictability, stability, grip, etc. IMHO, the Q3+ check all the boxes.

I'd recommend you stop using a belt sander on your tires! Wow the Angel GTs are a good for about 10k miles for me. I've not found anything that lasted longer.

Haha, guess we have rough roads here in Northern California.

I've had Q3s on my zx6r, and they didn't last very long on that. On the 1125, they'd go for maybe 1k miles, maybe.

I'm not trying to change a tire every month.

Dual compound is the key. I run Michelin Pilot Roads (they're up to Road 5 now). 12k rear, easy. 2 rears for a front. Hard in the center for mileage, gummy on the shoulders for grip in turns, excellent siping for wet roads.

If you're burning through them that fast, keep an eye on your pressures. Sounds like you're low, causing more heat, causing more wear. Fine for a track day, but not so much on public roads.

Q3+ are dual compound, at least in the rear. Not sure about the front...

34 PSI front, 36 PSI rear on cold tires is the recommended tire pressure for our bikes.

I had the Pilot Road 4's and put 5k or so miles on it in a year. Started to see a little wear in the middle but I'd say had another 3-5k left. Front still looked new.

I think the title of this thread should be (tires that stick and last). So far the Q3+ are lasting longer than the Q3.

I just bought a set of Q3+ to replace my second set of Pirelli Corsa's (at 6K miles...)

I hope you guys are right!

I use to run the Pilot Road (originals) and get about 10k miles on the rear and 20k on the front. Used them on my XB12R and 1125R and most of my riding was just daily commuting and some fun weekends at Palomar Mountain in California (spirited pace, but not FAST).

I get about 1800 miles out of a rear Q3 and about 2500-2800 miles out of a front Q3. I have just started switching over to the Q3+ so I can't comment on its longevity.

I've heard that the Bridgestone S21s are pretty comparable to the Q3s but last ~5K or so. No personal data to confirm that, though, but I think I'll try a set next.

Killing a sport-touring tire like the Angel GT in 3K miles is nuts. I figure it should last longer than that even if you're doing wheelies and burnouts everywhere.

Most of the wear happened on a 4 day trip over about 1100 miles. I noticed the day before the trip that the tire was leaking a significant amount of air and would lose about 7 psi over the course of the day.

I would fill it up in the morning to around 40 PSI and by the next morning it would be down to 31/32.

It's probably that underinflation that caused the bulk of the wear :/

34 PSI front, 36 PSI rear on cold tires is the recommended tire pressure for our bikes.


WRONG.

The tire pressure that's recommended is on the TIRE, not on the bike. The sticker on the bike ONLY applies to OEM tires.

Every tire is different - as we see in different compounds, different constructions, and different wear patterns.

GO BY THE TIRE.

What's printed on the tire is the maximum cold pressure. Filling to that you'll have long life and not very good grip.

I took mine (with Angel GTs) to a well-known tuner. He said 35 front, 36 rear cold is ideal for street use with that tire on this bike.

The pressure number on the tire is the MAX pressure the tire can hold, NOT the recommended pressure; start with the numbers in the manual and adjust to fit your riding style. Inflating to max pressure will provide an extremely hard ride, poor tire mileage, and poor roadholding.

If you go to the tyre manufacturers web site most give pressures for their tyres on different bikes, attached is the info for the Angel STs I am using.

Tyre pressures


Just checked and these are the pressures for all the Pirelli tyres recommended for the 1125R, works out about 38 psi rear and 36 psi front.

I don't believe I am wrong. Every tire I have ever looked at has Max pressure printed on the sides. I have never seen the recommended inflation pressure on any tire--car or motorcycle.

Here is straight from Dunlop and do you need me to show you what the recommended tire pressures are for the 1125R? I will give you one guess

I've always used the sidewall numbers, especially on dual compound tires. Never had a slip issue, always gotten excellent treadwear.

I stand by what I said - tires are completely different, brand-to-brand, compound-to-compound, size-to-size...I go by the tire. The manual is written based on the OEM tires, OEM brands, OEM compounds. I don't run OEM Dunflops, so I don't go by their pressures.

And, every tire I've ever read says "max LOAD xxx lbs at xx psi cold". I've never seen "max pressure" notes. Ever. Including the eight motorcycles I just checked right here in the showroom. And, if my understanding of my native English language is correct, phrasing like that means they're telling you the maximum amount of weight you can put on THAT TIRE, at their RECOMMENDED PSI.

Regardless of what the motorcycle is.

Weight is weight. PSI is PSI.

Go by what's on the tire. It is the RECOMMENDED PSI imprinted on the sidewall.

Wow some people are stubborn. Do us a favor. Go out and take a picture of where it says "recommended PSI" on your car or motorcycle tire.

MAXIMUM TIRE PRESSURE is what you will see.

The reason why they can't say recommended PSI is because the manufacturer doesn't know what you are going to do with the tire. Don't you think the PSI will be different for different loads and how exactly is the tire maker supposed to know this? The only thing they do know for sure is what the MAX pressure is, period.

Did you see what I pulled from the Dunlop website in prior post?

Here is the same thing from the Michelin motorcycle tire website:

I just looked at eight motorcycles right here. EVERY one said "maximum WEIGHT xxx lbs at xx psi cold".

Go read your own sidewall. Not once did one of these tires say "maximum psi".

Even if that's the case, that's far from "recommended riding" PSI as you indicate has been on every tire you have seen.

Also, what you are saying you are reading on the 8 bikes is the MAX pressure anyway. Read the circled part below.
