Removing tires from Mavic Enduro CrossMax wheels?

[Jim D]

A few months ago I got a pair of tubeless disc wheels, the Mavic Enduro CrossMax. I put on standard tires (WTB MotoRaptors) and tubes, instead of switching over to tubeless. I was going to switch out the tires tonight, and just tried to remove the rear tire. I have probably changed a couple hundred tubes over the years, but holy cow! I think I squeezed out ever bit of air, and the tires are still hooked under the rim. Is it supposed to be this difficult? Do I need to go tubeless after all? I sure am glad this didn’t happen on the trail.
THANKS

You have just witnessed one of the diffrences between ust and non ust wheels. The rim flange is designed to hold the tire bead onto the rim firmly. Also you have kept your tires well inflated for a good period of time which has kinda bonded the two surfaces together. Just a few seconds with a plastic tire lever will separate the two. You can run non tubeless tires on a ust rim without a tube if you want and should not have any troubles. I would strongly recommend using stans sealant inside the tire for flat prevention, and still carry a spare tube for field repairs. You will need UST tire valves. I have been running Mavic Crossmax XL rims with Kenda Nevagal ust tires for about 18 months on all terrain in the area with only 1 flat. I carried a tube, removed the ust valve, placed a tube inside the tire with a sidewall hole, pumped Up and finnished wakefield night ride. Not the best time to learn how to make the field service but it worked just fine. Good luck, Dave Marchyshyn.

Let me know how it goes as I just asked how to get tubed tires ON to the exact same wheelset - eventually putting in 70psi and letting the pressure pop them into place....

I never thought about the reverse...getting them off and then patched and back running again in short order.....

How do you like the wheel set?? I bought non disc ones

At this point, I inflated the tube again, and I’ll just hope I don’t flat! I didn’t have the time to fight both tires. I guess I’ll purchase the best tire levers I can find and try again. Don’t think I want to make the tubeless plunge just yet.
The wheels seem pretty sweet. I only have a handful of rides on them. The bike does seem a bit more maneuverable then I remember it being with the old wheels (OEM WTB Speediscs). Unfortunately I last rode my old wheels back in January, then wasn’t offroad for a couple months when the trails were so wet, so I don’t have an immediate comparison. Over the years, I’ve only heard good things about Mavic wheels.

FYI, from the Mavic http://www.mavic.com/ewb_pages/t/techzone_fiche_456.php website:

1. Deflate the tire. Then beginning at the point opposite to the valve,
unlock one side of the bead by forcing it into the gorge of the rim.
Continue in this fashion around the rest of the tire.

2. Without using tire levers, pull only the first side of tire over the top
of the rim around the whole rim circumference

3. Unlock the second bead by pushing it
into the rim gorge and
continue round the whole rim circumference

4. Remove the tire

They make it sound pretty easy...not my experience. No levers. Guess I'll put on some tougher gloves.

Soapy water helps with getting them seated. My Cane Creeks can be tough.

punga!

The key to breaking the tire loose from the rim is to push the bead toward the V of the rim - pushing more down than in. You 'should' be able to do this without a lever, so go easy if you are using the lever. Once you loosen the bead, remove the tube, then push the other side of the tire bead loose. Force one end - 6:00 - (both sides) of the tire as deep into the V of the rim as you can and pop the opposite end -12:00- of bead over the rim. The trick is to get the beads at 6:00 as deep into the V as you can which allows you to then pop the bead over the rim at the other end-12:00. I've been able to do this w/out levers.

I've been riding XT Enduro/UST Discs for two years & run them tubeless with Stans & Kenda Kharisma UST tires. For the first year+ I was using Slime but would flat too often. With Stans I've had no flats in the past 6 months. I did taco the rear rim about a year ago & it cost me about $150. Two weeks ago I broke the rear axle & that ran $50 with new bearings. I chalk both incidents up to rider error.

imo: I would give mounting UST's another try - going tubeless is worth the trouble. Use Stans & carry a tube. Good luck.

If you break the bead seal once a month and check the inside of the tires for debri or small thorns. You will have less problems when time to fix a flat. Dave M.
