Dual compound tyre wear

[MSTRS:Me]

Yea I'm running 38 in the rear, front is fine though. maybe put it up to 39 or 40?

Maybe. I run PR2 (duals) on my 750 at 37 in the rear, and I don't have a problem with a transition 'step". They wear remarkably even across the tread.

Really? That's good.

Cupping? That's another matter. And yes, I got that both ends. Front scoured badly on the shoulders (triangulating), probably because I ran that at 33psi. Didn't affect grip or feel, but I tossed them after 18,000kms.

Understood.

Anybody else got any experiences re this?

Remember when upright and braking (or accelerating) you have a load of force - gravity plus the downward force due to the pivot of the bike - pushing the contact patch into the surface. This means you can get away with a harder compound than on the sides.

I run 2CT michelins on the back of the SV. I am really happy at the way they are wearing. Half way through the life of them, and they are not showing the touring wear in the middle at all. The previous Michelins had a definate flat accross them by this stage.

Yes, the old "load overcomes slippage" scenario, and motorcyle tyres are in an almost constant state of slippage, so load matters a lot

Having my PR2's replaced tomorrow. Sides have worn out before the middle but no noticable 'step' the've done 11,000k.
Well pleased with them and more than happy to have the same again on a big heavy high grunt bike like the mighty 14.

PR2's here - no issues yet (5,000 kms).

I have noticed that they stick like Superglue and do not appear to actually wear much ........

This worries me as how the heck do they expect to make lots of money if my tyres don't wear out

[crazyhorse]

Dual Compound tyres are designed for the corners - so depends on where you live or the kind of riding you do, will depend on the wear you get.

I had battleaxes, and they wore out within 4km, but we do heaps of fast winding roads. I found that when they went off, they started to let go.

I now run Pilot road 2's. They're a good tyre.

Hey Guys,

I have a set of Battlax BT 45's on my hyosung

Had these front and back on my GSX600F, at 36psi they were still 3/4 new tread left in perfect nic after 3000kms, great tyre for mid weight bikes

I'm getting the same thing. Running Michelin PR2.

Steve

Im worried now Steve, I have these on the GIXXER (as the PR1 wore out in like minutes) and I commute a lot with that bike, shes heavy and big time power delivery
Im running 40psi on the back, rider and bike 310kg

Pilot Powers on the Duke...rear vanishing fast and I was gonn go to PR2's, but might well resort to Diablo's after reading your comment

Good thread, nice to learn from you guys

I had BT45's on a shaft drive 750 kawasaki a while back & do not recollect any unusual wear. I now like BT021's on my TDM, reasonably good wear, about 6k - 7k for a rear & so far faultless grip. The front & rear both show the signs of a hard ride, the front is rough & you can see on the tread edges that it is pushing. The rear will "blue" & if it's warm enough, do that chewing gum thing & ball up very slightly. I did a trip round europe a couple of years ago & the rear BT021 balled up in the middle after long motorway blasts so I don't think the compound in the middle is that hard.

I've run BT45 front and rears on my Honda Revere (600cc, 47 japanese ponies and 190kg) and then the D'eauville (650cc, 53 ponies and 240kg) for as long as they have been around. Travelled over 180,000km in total on them. The edges tend to wear out for me before the centres and I get 14,000 - 16000 km from a rear and 16,000 - 18,000km from the front. Pressures are front 31 in the winter and up to 33 or 34 for faster summer work. Rear pressures are 33 winter, 35 summer one up and 36 or 37 for fully loaded summer. Having found what suits my riding I've stuck with what I like.

Since when? They all go around corners

I had battleaxes, and they wore out within 4km.

I now run Pilot road 2's. They're a good tyre.

Only 4km , how did you get home?

Seriuosly I'm also running Pilot Road 2 and after 8000km of mostly commutting and the occasional weekend twisties they are holding up well with no signs of squaring off or scalloping. I'm running the rear at 40psi.
