Marathon Mondial 26x2.15 on Surly LHT

I recently ordered Schwalbe Marathon Mondial 26x2.0" tires for my Surly Long Haul Trucker, but was sent 26x2.15" Mondials by mistake.

I checked the Surly website, and they say the widest tires I can/should put on the LHT are 2.1".

Is there anyone out there running Marathon Mondial 26x2.15" tires on their LHT? If so, how do they fit? Should I keep these or return them and get the 26x2.0" tires?

Thanks,
Ed

Related question: Is anyone running them on the stock rims (which is what I plan to do).

I'm new at this, and it didn't even occur to me to consider what the implication of putting significantly wider tires on the stock rims would be.

You will be fine with these tyres on your stock rims and they should fit without any issues.

Actual tire size may differ from nominal, so measuring an inflated tire is only way to know with certainty. In the past, Schwalbe tires tended to be 0.2-0.4" narrower than nominal, but lately they seem to be pretty close to nominal. Mount tire and observe clearance/interference. You should check tire fit with fenders fitted if you intend to use fenders.

The implications of 2.15" tires on 17.5mm rims are that it may feel a little squirmy when cornering hard at lower pressures. It won't be a problem going straight with lower tire pressure or cornering with higher pressure.

You'll probably pressure a lower pressure off road and a higher pressure on pavement.

Ed, you should be able top put in some searches with the specific rim name, and see in images, what folks have done successfully-- specifically to see what clearances are between tires and frame.

I wouldn't worry about squirminess as it doesn't take much pressure to keep them firmly on the rim. My 26x2.00 Mondials are very hard at 50 psi. I ride them at 40-50 psi on paved roads and 35-40 psi on dirt roads. I've had no squirminess at all even at 35 psi. In the 2.15" width, they're probably fine down to 30 psi.

Regarding widths, I've seen people post pictures of their LHTs with 2.15" tires (Schwalbe Big Apple) and fenders, so I'm sure you'll be fine with the Mondials in that size.

and heck, if surly says you can go 2.1, then the few mm or so on either side with a 2.15 is not going to be an issue.

google images my friend, google images....

I've gone off the Mondials for anything except gravel road work, they have a lot of drag. The standard Marathons seem to roll better.

the standard marathons are also an excellent price/rolling/good tire choice for lots of uses.
I've used supremes a lot, and have ridden on regular marathons a lot also.

to me, a 1.5 or 1.75 reg marathon is a great touring tire that can handle all kinds of surfaces. My 2in supremes measure on my rims to the same as 1.75 in, and like that width for rough unknown roads, but still mostly on paved or reasonable gravel.

I havent used mondials, but they would be good for reaallly bad gravel and sharp stuff all the time, but if not on that outer Ubekestan type places, other models work great.

but back to this fellow, you just want to make sure the tire is not too close to the chainstays, if your wheel goes out of true, or for fenders, or mud etc.

and I guess only you know if you need a 2.15 vs a 2 (145g diff or so) and what kind of riding you are doing.

The back wheel should be fine. Surly themselves state that the frame could take up to 2.75" tires (without fenders). The fork seems to be the limiting factor on the LHT.

I think the application for Mondials is very heavy loads and very bad roads. If thatís not what yr doing most of the time itís like riding on good truck tires. Had some 700x42 Mondiales on a CrossCheck for commutting then switched to 38mm Schwalbe Almotion in the rear and 35mm Panaracer T-Serv in the front. World of difference in comfort, rolling and road feel.
