I've got a 756 with about 10 rides on it and it has started to chunk. I've been riding only on MX tracks that only have the occasional rock here or there. It's not like I've been riding in the dez on a buttload of rocks. It's still hooking up good (i.e. I holeshot 3 out of 4 motos last weekend) but I'm wondering if maybe anyone else has noticed chunking in similar conditions?

Maybe it's chunking when it spins over the starting gate?????? The new Maxxis IT rear has been rated outstanding, I may give it a try for hook up/durability next.

I ran 756's all last year and everyone eventually started to lose knobs. If you run lower air pressure than 15 psi the torque of the 426 will flex these tires until they weaken and start to lose knobs.

My 756 rears seem to start chunking on the side knobs first but still seem to hook up good. I was thinking about checking out the m-12 or s-12 next.

Yup sure have, ran one on my 250 2 stroke, looked like you just tried to peel the knobs off and left the next inner layer showing. Dunlop rep at the Atlanata SX told me to take it back to the dealer and have them send it back to Dunlop. He said it shouldn't do that.

Well at least I'm not the only one. I don't care for the 756 front just from the wear standpoint. I can run a 755 front 5x as long as the 756 front. Trouble is, just about everyone is backordered on them right now (I'm holding out).

I'm done with 756 rears, hook up is good but I don't have the $$ to be replacing this much.

p.s. I had a dunlop rep tell me a few years back that the off road tires were designed to last about 100 miles. I just laughed as I was riding that much in 1 to 2 weeks back then.

If the tires chunk and wear that quick, I will buy some Ching Chens, I dont go nearly as fast I did 10 years ago, and with my daughter riding with me, heh it beats paying 60 bucks a tire every 3 months

NAh I aint that cheap and beside those good tires puts maybe 4 - 5 hairs on the dingle berries :)

Man, my 756 chunked the side knobs on about the third ride, and this is on tacky but firm base dirt, awesome traction, VP Cycleranch, awesome spot to ride.

I will be trying a different tire VERY soon...

Is this a new problem with the 756 this year?

I have been using them for 2+ years and have not noticed this problem yet.

I had the same experience with the 756 rear - the knobs flew off on a hard packed, rocky trail. It had decent traction when new, though.

Hokie,

I dont' know. This is my first 756, I ran mostly 752s for the longest time until I moved here almost 2 years ago. This 56 is chunking quicker than the 752 I just had on.

Well it is a soft/intermediate tire, so I would expect it to chunk on the hard stuff.

My 756's chunked on the left side with the stock chain, no problem with a good o-ring chain. Normally run 15psi and ride sand, hard pack, and mud, with no problems. mike

RichB,

Try the Michelin M-12 front. I used to run the Dunlop 755 but tried the M-12 and will never go back to Dunlop.
