I google it for all over the evening and did not found an exact answer, I want to put Schwalbe marathon extreme 2,25 tires on my new Surly lht disc model with 26'' wheels.
What do you think about it?

Tire clearance - 26": 2.1" with or without fenders; 700c: 42mm with fenders, 45mm without fenders. Individual tire and rim combos affect tire clearance

I don't think 2.25" tires will fit in the fork. They will fit in the rear, but the stock fork is too narrow.

Here's a shot of some 26x2.15 tires in the stock fork. There is literally only about 2mm clearance:


However, the Marathon Extreme comes in 26x2.0, which should fit fine with fenders. I'd go with the 2.0's

Mmmm I found this man on Yahoo - https://www.blogcatalog.com/post/d075...f8ec231d6fd40f.
He is only one who said that he used on lht 2,25 tires I think it is very interesting, may be someone else???

FunkyStickman, thanks for the photo it seems that there is no free space for 2,25, but guy above inspired me a lot...

FunkyStickman

Some manufacturers don't make their tires exactly the size they say they are, plus it depends on the width of the rim it's mounted on. It may be possible, but I'd still go with the 2.0's

Read down to the bottom of the guy's blog, he even says it himself:

Lostin

I can't read anything cause it shows the mistake when I try to proceed for the whole article, 2,0'' is also a good width for touring tire, now I have set of Kojak, but 2,25 is more stable I think and is better for off-road, so what definetly he is saying about why he would start over with 2.00"?

Just go with a Surly Troll, I have a LHT, but cant help to think of how amazing my troll would be for a off road touring bike.

FunkyStickman

He said the 2.25's were such a tight fit, he was constantly having to adjust the wheels to keep them from rubbing. Other than that, they were perfect.

The Ogre is a good bike too, has lots of options if you're not worried about it not being a traditional "touring" bike. Plus it's orange!

Lostin

FunkyStickman thanks again, Troll and Ogre no doubt are good bikes, but I already got one mtb frame and after couple of 40 day long trips in Asia and Europe realised that when you have 20 kg luggage on the rear all pros of mtb geometry sucks IMHO. In long trips the main thing is touring geometry=comfort and new 26" lht disc trucker gives all that... I want to believe it))
I have a set of incredible strong wheels - 26" rhino lite xl rims with dt swiss spokes and sealed bearing dmr revolver hubs, so it will cooperate fine with new disc trucker. What tires is concerned, I will stop on newest Schwalbe Marathon Mondial 26" 2,15 - it would fit just perfect lht disc trucker fork as far I understand from the picture above...

The last thing I am thinking about is the size of the frame to choose 58 or 60, it is touring bike, but with 26 wheels. I am 183 cm long and have 89 cm true cycling inseam, what would you reccomend? I used this calculation 89*0,66=58,74. Are my calculations right for the touring geometry frame but with 26" wheels?

FunkyStickman

I would go with the shorter frame, it will be difficult to mount the bike and straddle it loaded if you can't stand over it.

Lostin

58 frame has standover height - 83 см
60 frame - 85 cm
My inseam 89 cm so, in both options, I will stay firmly on the ground, but distance between top tube and my crotch area would be different, so it is better to leave more cm with 58 frame or a little bit less with 60 frame? What option would be better for touring needs?

FunkyStickman

In that case, you'd want to see which one has the right size top tube length for you. There are several bike fit calculators that can help you with it. I prefer smaller frames for a more upright riding position, you might not.

Lostin

58 would be the best one than, the only trouble is that lht disc version sellingS begin only in april((((

Potentially a dumb question, but why couldn't you get a different fork with more tire clearance for the LHT? As long as the length, rake/trail, were similar then would it matter? Or do you need the low-rider mounts? Or possibly something else I'm over-looking. But if the only limiter is the fork clearance then it "seems" simple enough to just swap out the fork, assuming the geometry works after the swap.

FunkyStickman

You could, it would be possible, though there aren't many other 26" forks shorter than the LHT one. The Big Dummy fork would be close.

Lostin

It is a possible way of building the first tourer for my purposes, but question about tires was just theoretical, new mondials from schwalbe goes with max size 2.15 and I think that is quite ideal option as for road, so for off-road conditions.

positron

50mm tires are sufficient.

For nearly anything carrying touring weight, anyway.

I rode From Washington D.C. to Denver with the 2 inch marathon supremes' and they worked like a champ. But it was pretty overkill and I could feel the power being sapped from me due to the tire's width. I would recommend 1.5 in or 1.75 for road. You do feel like you can take on anything with the 2 inches, but if you don't plan on encountering gravel or anything off-road, I suggest thinking of a smaller width.

enigmaT120

Those are what I have on my Fargo and I like them. But I do ride on several miles of gravel each way commuting, and for fun riding will almost always go up on the logging roads, not on pavement. I don't think they will work if I get snow though.

LeeG

riding home last night in a downpour I have to say that 2" Supremes make riding through puddles a lot more secure given the ruts hidden in them and I'm not riding at high speed.

positron

There are 1.6 marathon supremes (40mm) in 700c and 26. I have them in 26 and they are great. Still overkill for paved roads, but great for mixed terrain.

I also am 183cm in height, with an inseam of 88cm. I have just test ridden the 56,58, and 60cm LHT. In my case, I felt the 60 was too big, 56 too small, the 58, ahhhh just right. I'll be staying with drop bars. My only point of indecision is whether to go with 26" or 700c tires. I'm leaning toward the 700's though. Good luck.
