curently on my 05' XR650L i have maxxis deserts. The sizes read as follows:

Front- 80/100 -21 51m
Rear- 110/100 -18 64m

I was wondering what are the largest (tallest and widest) tires that i can fit on these rims? also what are the numbers telling me? height vs width? what is what? and what are the numbers before the "M" telling me?

thanks, you are all bike gods!! :thumbsup: :lame: :p

I have a King 5.10 on mine. I just put it on in August. I went with a more street version because I commute with my bike. It is the largest tire I could put on stock.

The 51 and 64 are a rating number that has to do with the load the tire can carry. Car tires have the same numbers. The "m" is the speed rating. Don't know what "m" is though. The tires on my Jag XJ6 are 225/65-16 and are V speed rated. The number there is 97V.

The Maxxis tires run a little narrower than others. A 120/100 Maxxis is about the same as a 110/100 Dunlop. I run the 120 Maxxis desert IT on my XR600 and I think it's about the best overall tire I have ever used. No problem with it fitting. Not quite as good traction as a 756 Dunlop, but it lasts twice as long. I got tired of being in the "tire of the month" club.

Due to what I have read here, I've never tried the Maxxis front. No one says good things about them. I still run a Dunlop 756 up front.

80/100-21 51m

80/100 means the tire is 80mm wide and the sidewall height (rim to tread) is 100% of the width (also 80mm)

-21 means it fits a 21 inch rim

I don't know what the m51 means, but it's probably a speed or load rating.

http://www.cycleshop...cycle_tires.htm (similar)

The alphanumeric hieroglyphics on a tire's sidewall offer a variety of info. Size can appear in inch, metric and/or alphanumeric denominations. All three interpret the size in terms of its width, aspect ratio and diameter of the intended rim. Here (160/90 H 16) 160 is the cross-section width in mm; 90 is the aspect ratio (the relationship of the tire's height from the rim to the road to its width, expressed as a percentage of section width); H is the speed rating. 16 is the rim diameter, in inches.

An S-rated tire is designed to cope with sustained speeds up to 112 mph. An H-rated goes up to 130 mph, a V rated is to 150 mph, and a Z-rated tire is will go more than 150 mph

I have seen a XR600R with 90/90 21 front and a 120/90 18 rear, thats pretty friggin big! Tyre type, tread pattern and tread compund mean more than sheer physical size. What terrain do you spend most of your time in? Since it's an L do you still street ride it? If so look at the Karoo II's and be amazed at not only the traction off road but on road too for a street legal knobby.

The Cheng-Shin C760 5.60X18 is a very large tire and is a pretty good one to boot, wears well, great traction on most surfaces running 8-10 psi. This tire has a stiff, heavy carcass, I even ran one flat one time for over 30 miles with no ill effects.

over on ADVrider somebody posted that the 140 and 150 Teraflex are exactly the same tire and measure the same size.

I used to have a 5.10 Kings on my XR650R and it was a close fit with the chain at the shortest setting of the adjuster block. Now I have a 130 Dunlop D606 on the rim and it seriously rubs on the white plastic (crack crack crack when I push it backwards with my butt on the seat), plus there's not much air on the sides. The only way I'd be able to fit a Teraflex in there is with a longer chain and the wheel slightly back from where I have it right now.

Just went to a pirelliM21 140-80-18. Took off the top chain guard and it fit like a glove. Definately trying a terraFlex this fall though.

Will I be ok with a 120/80S Avon Distanzia on the rear of my 650L?

I just stuffed a 140/80/18 Dunlop D908RR on my 650L. Chain guard had to go, after it was gone though it fits nicely. This tire is HUGE.

Also Dunlop D908. I think the rear only comes in one size which is 140. It's fat. I like it, good in soft sand / dunes and on road (gravel and paved) and lasts long. Never tried in wet weather or mud so I don't know about that.
I just got my second one, here it is, not on bike yet.

and the old one on the bike, tread a bit low... its on ab XRR, no adjustment needed, fits fine. I think the rim size is same as XRL, correct me if I'm wrong...

BTW the D908 has unusually stiff sidewalls so it's a bit tough to get on and off, but it means you can run very low pressures, I go down to as low as 8psi in the dunes in hot weather. A buddy on a KTM 950SE was riding his rear D908 totally flat for quite a while (by mistake, it's a long story...)

I read a report from a guy on Advrider who had a flat on one of these while on the TransAm Trail and damn near had to walk. He says it was next to impossible to spoon off the rim with conventional tire irons and wouldn't consider using another one because of it.

Are they really that hard to spoon on and off?
