    Narrowest Tires For 54cm LHT?

    I have a 2009 Surly LHT, it is a 54cm frame. I'd like to install the narrowest tires possible. I'm thinking no narrower than 26x1. Is this an acceptable width tire? Will it fit the stock rims? Yes, I am touring with full pannier loads on this bike, and currently running 26x1.5 tires on it.

    Thanks

    depending on the total weight a 1 inch tire will be too small and the risk of pinch flats will be higher.

    Thanks for the reply reptilezs

    I guess I should have mentioned tour weight. MY LHT fully loaded is 75-80 pounds soak and wet. Then add my fat a%s of 175 pounds to mix. The tires I'm looking at have 115 psi max.

    Yeah, I'm aware of the pinch flat risk, I'm curious if a 26x1 will fit.

    yes it will fit, whether you like the ride/performance is up to you.

    You would be better off with a 26x2.10 fat tire.

    Good on the fit then, thanks. I tend to pefer a firmer ride as opposed to a soft, squishy, or bouncy one. As for performance, I'm not sure if there would be a sacrifice or just a different feel, like it handles quicker? I like a tire with higher air pressures too, they seem to help in the pinch flat arena.

    KDC thanks for the response, I'm looking for a faster pace. My 26x1.5s are ok, but I find I have to work to keep up with those sporting 700mm wheels. Somehow I think 2.10s would make my LHT even slower. Mind you, I'm not looking for a speed demon (I didn't buy the LHT for that), but a bit faster would be welcome. I realize too that I should balance performance with endurance...so I may have to stay with the 1.50s in the end.

    I'm looking at some Schwalbe Durano 26" Road Tires. They offer a 26x1 and a 26x1.35. I'm thinking the 1.35 is not much different than a 1.50, but it does offer a higher max psi which might be what I'm looking for.

    Personally, I wouldn't run anything less than a 1.3 on that rim and that is pretty narrow.

    1.5 is pretty much optimum for road use for that bike which is why Surly specs that width in the first place on their completes.

    +1 for 1.5

    As an LBS I can tell you that any use heavier than for commuting on 26" wheels, that 1.5" tires are the minimal for most road conditions. And though you might (key word here "MIGHT") get away with a 1.25s (and there are people who've done it I'm sure) IMHO you are putting yourself at risk of serious injury. I would rather know that "my tires are designed to, and will support my load" versus "my tires aren't designed to support my load but they might," The risk to benefit ratio is negligible at best and besides narrow tires doesn't always equate to a faster bike particularly with a full load. On this last RAGBRAI I had no trouble keeping up with the pack loaded on my LHT with 700 x 38c tires. BTW I weigh 90 kgs.

    If you have 24.5mm wide Alex Adventurer rims then 1" tires can fit but it'll be obvious they're too small as the tire is barely wider than the rim, besides there's no practical reason for 1" tires carrying 250lbs of which 30lbs or so is dead weight sitting on the frame that you cannot hop over holes,ruts and rocks. You will not gain any benefit for higher average speed with 1" tires over 1.25-1.5" tires if you're not already riding at a fast pace, ie. above 18mph or so. That is primarily a function of hp. If you're struggling keeping up with 1.5" tires and touring load you're going to struggle with 1" tires and with 1" tires I can pretty much guarantee you'll have sidewall or rim damage/scrapes.

    I wouldn't put on tires smaller than 1.25" on 25mm wide rims where there's 30lbs of dead weight sitting on the bike. 1" (25mm) tires go on road rims that are 19-22mm wide.

    Once you put on fast rolling tires that are inflated to their proper pressure it's all about the motor/lungs and whether your posture on the bike is optimum for putting out that effort.

    Pasela TG are fast tires. Continental Sport Contact is a fast and durable tire. The 26" Schwalbe Duranos are for racing.

    These are the smallest/lightest tires I'd consider. Put the Pasela TG on the front and T-serv or Rib-Mo on the rear.

    Unless you're riding some kind of heinously heavy 1.5" tire with extra thick mixed tread I don't think you're going to have much of a speed difference with a touring load on a 1" tire.

    ps, when you say "full pannier loads" do you mean front and rear panniers?

    yep, pretty much more risk to tire/rim damage with little speed benefit as that's primarily a function of power and aerodynamics.

    if you're looking for a faster pace, you're looking in the wrong place. Wider tyres roll better than narrow ones, and with a loaded tourer the aerodynamic and weight-related advantages of skinny tyres, which make a big difference on a road bike, will be barely noticeable.
    There have been many days when I haven't felt like riding, but there has never been a day when I was sorry I rode.

    check out the chart, 1" tire for 165lb rider is about 100psi and they say add 1% for each added kg of gear. So for you plus 40lbs of gear (35lb LHT) that's about 125psi. I gotta say you're going to be experiencing some interesting treadwear on racing tires pumped to 125psi loaded down with 250lbs of bike and rider where the rider can't hop that 75lb load over road hazards. From my experience not all tubes hold 125psi all day and the margin for error disappears really fast once the pressure drops on skinny loaded tires.

    Great info from everyone! That's the reason I asked, I didn't really know. The consensus appears to be...I'm best off with the 1.50s. I have to agree. Thanks everyone...outstanding responses, I'm better off for them.

    Mavic says 28mm for their A319 rims (700c rims that have a similar purpose to those on the LHT).

    You can use a fairly wide range of tire widths on a rim but you can go too narrow for the rim. The tires require some lateral force to keep the bead on the rim. If you go too narrow, that lateral force is reduced.

    Pinch flats (and other support problems) are reduced by wider tires and higher pressure. Both of these combine to counteract the force of the load. To get the same benefit, a narrower tire requires higher pressure.

    Lee's post is a good one. You really aren't going to see any increased speed and wider tires are going to be more reliable and more comfortable.
