T120 Tire Life

What are T120 owners seeing for tire life? My stock Pirelli's lasted almost 7000 miles and I replaced them with Avon Storm 3's. The front is done at 6000 miles. The rear still has a lot of tread and is a little squared but not as bad as some I've had on other bikes.

I pay attention to my tire pressure and don't ride overly aggressively. The front developed a noticeable wobble or vibration on the handlebars on low speed tight corners, especially downhill. I found that the tire has developed a little bit of pitting and that was when I found I was also pretty low on remaining tread.

Is the T120 a bike that likes to have a new front tire every 6000 miles?

I got 15K miles out of the stock tires on my T120. The front was almost to the indicators and the rear could still have gone a little further. Id say Im not an overly aggressive rider either. Im not sure how to explain the difference. I check pressure regularly.

The stock Pirellis on my T120 went 9,700 miles, by far the best life of any set of M/C tires I've ever had. The rear tire never did square off, and probably had several thousand more miles in it. The tread on the front tire was thin. This is the first time I had a rear tire outlast the front. Usually, the front lasted easily twice as long as the rear.

Almost 11k miles on my OEM Pirellis. Changed them both because the front tire was wearing thin, but the rear tire would have gone several k more miles. I replaced the Pirellis with Avon Spirit STs and only time will tell how far they go. I will say this, though: They handle so much better than the Pirellis ever did and I won't really care if they don't go as far.

With three out of three responses having way more miles then I am experiencing, I really wonder what the difference is? I keep pressure at 34 front, 38 rear. I weigh around 240, typically ride around 75-80, but live in extreme heat so I ride in temps above 105 most of the time (I try not to ride after 110. I doesn't feel good).

Hot road temps won't help with long life of tyres maybe find a duel compound tyre, hard in the middle and soft on the sides.

My front Pirelli went at around 7k, and I just replaced both. The front stock tire is bias ply, and the rear is radial, but lots of people say on here that it doesn't matter.

I replaced both with Continental Road Attack III tires, and they have lasted about 10k now and seem to have plenty of tread left.

Here's the best explanation I've heard yet about that and I heard it from a Triumph factory representative who was visiting the dealership I bought my bike from:

The decision to put a bias-ply on the front was based on the recommendation of Triumph's legal team. Radial tires have softer, more flexible sidewalls than bias-ply tires so they're more likely to come off the rim in a catastrophic failure, and things never go well when a front tire comes off a rim at speed. The likelihood that either kind of tire will come off a rim is extremely remote, but lawyers, barristers, and solicitors can't seem to think in anything but worst-case scenarios.

FWIW, I'm convinced that higher temperatures cause faster tire wear and I can back that up with some personal experience:

I lived in Quincy California from January 1980 to November 2001 (21 years). Quincy is in the geographic center of the Plumas National Forest and just about all the roads up there are twisties. We had hot 100+ days up there but they were few and far between and typical temperatures during the summer were in the 80s.

When I moved back to Southern California I expected my tires to last longer because the roads are a lot straighter down here, but that isn't how it worked out. The same car with the same brand and series of tires on it got 15k-20k less miles before they needed replacement. I'll add that my driving style remained basically the same. The only real difference was the higher average temperatures here in So. CA.

And understand that I've lived near the coast since I moved back here and it's a lot cooler here than it is inland and definitely cooler than it is out in your neck of the woods, ETC. Oh wait: You don't have much in the way of woods in El Centro, do you?

I weigh 170, seldom cruise at high speed, and run my stock Pirellis at around 34 PSI rear, 30 front. I think your tires are working harder than mine do, plus you're riding in warmer temperatures. It gets hot here, too, but I'm off of the roads for the day before 9:00 AM.

My T120 has also been on a bit of a diet. It dropped six pounds at the decat, and over four more when the front brake discs were changed for the floating discs of the T100. Also gone is that heavy headlamp heat sink, removed when I installed the T100 headlamp that is so much better on high beam. That's about 12 pounds altogether. That's half the weight difference between the stock T120 and T100. The additional 12 pounds gets me a sixth gear, 300ccs more displacement, dual brake discs, a center stand, and the low grab bar, all with no fuel economy penalty. I'll take the added weight!
