  • Offroad/All terrain wheels

    Hey guys,

    I was hoping to get some advice on tires I can put on when going on trails or going to the beach. What are some affordable 2 inch rims and tires? If price wasn't a factor, which are the best rims and tires? I really like using my freewheel and smartdrive but my marathon plus tires always get stuck in sand and gravel roads so im hoping this will help with that. Thanks.

    Also, should I get a different size wheel if I normally ride on 24's?

    I use Syncros 507 rims, DT Swiss spokes, and Maxxis Holy Roller tires, with Rogue offset wheelchair hubs (no longer available). Holy Rollers are by far my favorite tire. 2.95" wide (on a 1.25" rim), with just enough tread but not enough to get clogged or track much.

      If your rims are standard 24" wheelchair rims, you need ETRTO size 540 tires. You can put a 2" tire on a standard width rim. But the 24"/540 size is a limiting factor as there are only four 2" tires I'm aware of in a size 540.

      The first two are Kenda's NEVEGAL and KOBRA. Both of these come in a 50-540 size.
      Specialized has RHYTHM and the COMPOUND tires in a 24" size, but it's not clear if that's ETRTO 540 or 507.

      Always use the ETRTO size! it's universal and exact.

      If you want a better selection of tires that are 2 inches wide or more, you'll have to buy a new set of wheels. Sizes 507 and 559 offer many more choices in a wide tire. I recommend getting a set of 559 size wheels (bicycle size 26" and wheelchair size 25" are both ETRTO size 559). Then you'll have a hundred mountain bike tires to choose from.

      If you do get tires that are 2" or wider on any size wheel, you may not be able to grab the handrim because the tires stick out too far. If so, you'll need to attach riv-nut mounted rims to the spokes. See my guide here.

      If I were to build a set of off-road wheels and had an unlimited budget, I'd custom build a wheel using "fat bike" parts. These tires can get up to 5" wide, but the total build cost would be about $700 a pair.

        My 507 rims with Maxxis Holy Rollers are a near perfect ride height match for my 559 Spinergy LX wheels with Marathon Pro tires.

          If you have ETRTO 507 there are some cheap options in tyres https://www.veetireco.com/listings/j...lty-crown-gem/ for example at $10 per tyre.

            You also have to watch the fit. I have a set of 540 rims with 2 1/2 inch kenda knobbies. They are taller than my every day 559 by 1 inch wheels and tires. So the chair sits higher on the knobbies. The knobbies also have to be spaced out so they don't rub the chair.

              Thanks! always trying to see what other people use.

                Thanks for breaking that down for me. If you can fit 2 inch tires on one inch rims what are the advantages of using larger rims? Besides a larger range of wheel options.

                  That might actually work out perfectly. My freewheel makes my chair really tippy so that could help with that.

                    Also, if I got the kendas and put them on a 1 inch rim I have laying around what kind of tube should I get?

                      You will need wider tubes. Kenda sells 24 x 1.95-2.1 tubes (50-540 ETRTO)

                      Also, with tires that wide you may not need a handrim. It may be easier to just push the tires.

                        I have these 2.1" Kenda knobbies for taking my dog to the dog park. They'd probably still be a struggle over gravel and sand. I'm not sure how wide a tire has to be in order to be effective on sand and gravel. But you don't want to go any wider than necessary. Because at some point you can't effectively push the handrims and at some point you can't effectively push the tire directly. I don't know where that cut off point is. It would be interesting to know.

                          Exactly what I am looking for. Can you interchange the two without having to adjust the brakes? How about rear axle spacing?

                            Unfortunately the hubs I use are no longer available. They include a ~1" offset on the inner potion that spaces them out from the frame. This can also be accomplished using washers/spacers on the axles if they are long enough. I use D's Locks, so no issues at all with wheellocks, but I'd imagine regular clamp style would work OK. The tire sizes aren't 100% exact, but maybe .2" difference, knobbies being ever so slightly taller. Air pressure is very different too, 65 vs 145 psi, so that may be well enough to make the slight difference in size no probable from a clamping perspective. Not 100% sure though.

                              I live on The Chesapeake Bay, and I've yet to find any tire that works effectively over sand. Gravel is hell, too. Without a Freewheel I don't even bother. With a Freewheel, my 2.95" Maxxis still suck.
