Just wondering, will a 26x2.125 tire fit on a rim that originally came with 26x1.75 tires? I've got these Western Flyer rims here and maybe I want to put larger tires on. I know it will be a tight fit on the bike, but they should clear.
I didn't have any problem with my rims. http://www.creativegrowth.biz/my_first_ ... /index.htm
The problem I had was with clearance in the back of the frame.
I had to "true" my back rim and get it perfectly aligned in the frame to avoid interference.
20"x2.125 tires (like the Schwinn Slik) fits only on S2 rims, they are too small for S7 rims. I know that because my slick tire drove me crazy when I tried to instal it on a S7 rim then I looked for information on Schwinn tires & rims size chart (thank you Sheldon Brown, RIP).
I never had this kind of problem with 26" cruiser rims.
Any 1 3/4 wide rim (except Schwinn S-7) will take any standard 26" tire 1 3/4 inch and up. (1.75 will do 1.75+ all the way up to 3.0 or 4.0 inches wide)
The only thing to watch is frame clearance, if your current 26x1.75 tire has at least 1/2 an inch on each side it will "fit" but you want to allow for the tire to bulge when you ride so maybe a little more.
Most middlweight (bikes that came with 1.75 tires) will accomidate 2.125 balloon tires fine if the fenders are off.
I tried installing a set of Duro 26x2.125 on my Schwinn Typhoon 26x1.75 rims yesterday and they weren't even close to slipping on.
Any tips? Am, I just out of luck getting them on these wheels?
Schwinn S-7's are a different size rim. That was to make sure you bought only Schwinn tires, the diameter is just large enough so standard tires won't fit. You must get the S-7 tires which are still available. My 2 speed is an S-7 wheel, I want a fatter tire, but the 26 x 2 x 1 3/4 is the widest. Here's a site that has them.
Standard tires are 26 x 1.75, 26 x 1.95, 26 x 2.0, 26 x 2.125, 26 x 2.35, using the decimal point. The standard 26 inch rims will take all those tires, just clearance with the bike is the issue then. I even have 26 x 3.0 Kenda flames on standard 26 inch rims. The lightweight skinny 26 inch wheels are a different story also, that is a different size, 26 x 1 3/8.
It gets confusing, but sticking with decimals instead of fractions usually works. Take a wheel with you when checking out new tires if you can.
Dan, this is a 2.35 tire on a 1.75 rim. It's not a problem fitting the rim, the clearance issues can be a pain. If it's going on a middle weight bike have a spoke tool handy, any bends in the rim the tire will rub. On my Spaceliners I had to lengthen the drops out 3/8" so the tire could be moved back farther for more clearance. And forget about a fender there is no room. Clearance depends a lot on the frame design, the Flighliner pictured has the 2.35 tire and no modification were needed, it's tight but the look is awesome.
