I Ride in rocks, sand and hard pack. Fairly aggressive (I think?) rider on two track and single track. Bridgestone 403, 27 hours, replaced with a Maxxis It thinking it was more suited due to torn side knobs. Now have 17 hours on the Maxxis and noticed many of the side knobs are also torn through! What should I be running?

Some tires are prone to ripping knobs off, and on rocky conditions they will often get sliced by sharp rocks. That being said, ripping nobs off can also be a sign of too much air pressure in the tire. However, 17 hours is a fair amount of time on a tire, the casing will begin to get soft after only a few hours or riding, so it likely isn't an air pressure issue.

The Maxxis IT front was never a good tire. Torn side knobs are somewhat common with this tire. Tire pressure could also be a result of torn side knobs, because a higher pressure doesn't allow the tire to absorb as well. What tire pressure are you running? ( I know KJ said it most likely isn't a tire pressure issue, but it doesn't hurt to know).

Also I see you are from Nevada. Do you do any MRAN ( the southern Nevada desert series) racing? In the types of terrain these races go through ( sandwashes, lots of rocks, silt, soft whoops, slick dry dirt with a hard base) I've had good luck so far with a Dunlop 755 or the newer Dunlop MX31.

Jim,
I ran 15 with the Bridgestone and 12 to 13 with the Maxxis. I've been running the lower pressure since installing the heavy duty tube. I dont race the MRAN, I'm in Northern NV, but the terrain is probably similar to what you describe. Not sure what model of Dunlop it came stock with but dont recall having any issues with it. Looks like I'm going back to Dunlop :busted:

Also, I've had very good luck with the Michelin MH3 front tires.

Having said that, my friends who are heavier and have different cornering styles (read: much more aggressive/faster) can rip knobs off easier on the same tire as mine.

If you are getting 17 hours out of a front tire in that type of terrain before starting to tear side knobs I'd say you are doing okay.

I don't think thats too much pressure, I usually run about 14 with a heavy duty tube. Like everyone else said, 17 hours is a fair amount of time on a front. Give a dunlop 755 or MX31 a try, or if you still want to stick with Maxxis I've also had pretty good luck with the Maxxis SI front:thumbsup:

Iwas running the Maxxis IT and swithced to the Maxxis SI and have much better luck. the side knobs stay on longer and the front tire sticks to the ground much better. I am much happier with the SI

The new SI is a radial, Anyone try one yet?

I have been very happy with the Dunlop 745F up front and the Michelin MH3 on the rear. I race most of the MRAN series and do a ton of trail riding and the 745F up front holds up VERY well. I usually change the front tire every 8-10 months and the rear every 2 months or so. If I were to guess, I would say that I am getting at leat 25-30 hours on my front. I also ride in a lot of varied terrain from sand, silt, gravel, rocky, fire road, and the occasional MX track. I usually keep the front a little higher in pressure than most 16-18 psi up front and 12-14 out back, but I also haven't had a flat in over 3 years.

Good luck!

Which tire lasts longer in intermediate terrain the MH3 or MS3?

They both hold up great. The MH3 is for medium-hard terrain, and the MS3 is for medium-soft terrain. I think the MH3 is the more versatile one, it works great on medium and hard ground, and still works pretty well in sand and mud. The MS3 works a little better in sand and mud, but seems to be a bit unpredictable on hard ground and skip out from time to time.
