2.15 vs 2.5 rim
im going to buy a 18' rim and want to know any advantages/disadvantages between the 2.15 and 2.5...
got a 110/90/19 M5B those knobs are huge, but the 18" looks even better

the 450 will have less power and will be harder to start, and will be heavier, but to make up for it it will require more maintenance.

Save the unsprung weight and get your boner (tubliss) cuz that M5B is prolly 20 pounds. I run 110/90/19 knobs and paddles on both size rims and it works fine.

im getting tubliss but i need to know if a m5b on a 2.5 rim will work with a tubliss, if not ill be going 2.15 tubliss route,
i heard the desert it will work on a 2.5 tubliss, i dont know for sure
I was racing my friend last weekend on a fire road and i had to keep it pinned for a little too long and i hit a 4" high triangle rock 4th wound, both tires had 15lbs+ front was fine, shitty dunlop756 poped the tube lucky i didnt bend the rim, or bail
but i got a m5b and i will never go back, good sidewall and crazy traction

15+PSI??
oviously it wasnt enough for that shitty dunlop 756poped the tube lucky i didnt bend the rim, or bail
i hit the rock dead center it poped the tube in the middle OF THE RIM, NOT THE SIDE... i officially hate dunlop
thats another reason i want tubliss so i can run normal pressures = more traction
i run 15 in the m5b and it seems like the sidewall is a lot stronger/ strong enough
the 450 will have less power and will be harder to start, and will be heavier, but to make up for it it will require more maintenance.

what kind of tube was it? I run HD tubes and have never had a pinch flat, I normally run ~10psi and ride over some razor sharp rocks, the type that rip knobs off.

stock
but it didnt pinch it, it destroyed it
the hole is where the valve stem goes right in the middle,through the top and bottom, but rotated a bit
got kenda hd tube now

Yeah, I didn't even ride my kawi once on stock tubes, those were swapped out for the ultra hd michellins as soon as I brought the bike home, same for all of my other bikes, I tried a stock tube once in the sand dunes and I ended up with a flat when I got back to camp and didn't even know when it happened, but did remember it turning like shit not long after the ride started.

Also, if the tube was pinched in the center, how does that relate to a "crappy tire" with too soft a side wall?
The 756 is a great tire. Its replacement, the MX51 is the most widely used and sold tire I have ever come accross in my "career". Litterally every single desert racer I know or have come across is running it in the 90-100-21 taller size and loves its performance (my self included)...
Most of the guys doing local MX here run it also, just in the smaller 80-100-21 size...
Taking a huge heavy tire like an M5B and then trying to minimize weight by going to a Tubliss is like a fat chick ordering a double big mac and a DIET coke...
Run a better, much lighter tire and a HD or UHD tube and you will save a lot of money AND unsprung weight...

I run them in the desert as well as MX and in a lot of very very sharp volcanic shale and they last every bit as long as a Maxxis Maxxcross if not even better. Plus they have much better traction and weigh 2 pounds less!

I like the MX-51 I have on the back of the YZ.
It seems like it would make a FANTASTIC track tire.
For off road, it doesn't behave quite as well as the M5B (not that I've been able to try on on the YZ yet), but much better than any of the other rears I've tried. It is not as predictable transitioning from one terrain type to another, which I do a lot of.
But what do I know? I'm just a slow old dog who never gets above 40 mph.
.......Wasn't this a rim thread?

D756If you race mx and put new tire on each race weekend it was a good choice
i can agree with that, but i hate it for offroad
so has anyone tried a tubliss m5b and 2.5 rim ive heard some tires work, but want to know for sure
the 450 will have less power and will be harder to start, and will be heavier, but to make up for it it will require more maintenance.

your choices are VERY limited with a 2.5 rim if you want tubliss. Basically you need a tire with 12mm or more bead thickness to run a tubliss. The desert IT has 12 or 13, not sure what a IRC has. If it's less you are not going to hold air. The tubliss was designed for a 1.85 to a 2.15 rim. Porky desert IT has a very thick bead/sidewall allowing it to work on the big rim. Don't hold your breath for a 2.5 tubliss, they can't even keep up with demand with popular rim sizes. I've talked with the inventor, jeff at least 3X per year for 2+ years now pleading our case..........
Not sure what off road you are doing. I did a 2 day 160 mile ride last year on a 756 that wasn't worth a crap, 1/2 gone. Went up some of the nastiest hills I've ever climbed. the kind littered with several obstacles, ie bikes that couldn't make it. Many times I had to come to a complete stop. I was able to take off much to my disbelief, I was amazed, I was sure I was going to have to go back to the bottom.
My tubliss setups are going to run 2.15's for the time being, lighter in many ways, better traction than a tubed setup should make it similar or better than a 2.5 with a big tire traction wise. Just the extended tread life and way easier tire changes are enough to justify it.
I have a couple extra rear wheels I built from scratch wtih 18 2.5's, One will get a desert IT and a tubliss at some point seeing as I allready have the parts other than the tire.
I just remembered I have an extra new never installed 18 on the shelf if you end up needing one. I would trade it for a 19"

If the nastiest hills you ever rode allow you to stop and then start back up again you need to come ride in SoNev!seanmx57 wrote: Went up some of the nastiest hills I've ever climbed I had to come to a complete stop. I was able to take off much to my disbelief

Thats very odd, every person I have talked to locally with a tubliss says its in no way easier to change a tire?
