I run a 1.9 tire on my cruiser. I also jave a washer inside between your wheel and the frame to move the wheel over a little. One usually doesn't hurt the wheel engine alignment.

Good advice Deacon.

I run a 1.90 also- plenty of room. But if it's just lightly rubbing, but not hard enough to feel resistance when pedalling, don't worry too much about it.

Zoomcat, I had to go from a 26 X 2.125 to a 26 X 2.00. It still rub's a little but I have had no problems.

If you have a dished rear sprocket with offset rim,install with concave side out.
That is with teeth furthest from the hub.If chain then is hitting fork try spacing fork out with washers.Installing and removing sprockets goes alot quicker if you chuck a socket with drive in a cordless drill.Make sure sprocket is not tilted but in a parallel plane with tire.If tire is running true take spring clamp and clamp a popsicle stick or similar to fork barely touching sprocket and turn wheel to see if sprocket is running true.Tighten bolts where its running out.Ron

Another thing you can try is to tighten the spokes on the opposite side of wheel to slightly dish your wheel away from the chain.I wouldn't overdo it though.Ron

Any other way to keep the chain from hitting the tire besides getting a narrower tire, or with the tensioner? I don't want to go any narrower with the tire than it is now, and the chain keeps hitting the knobs on my tire. Sometimes when I ride it jerks kind of violently. Also, my frame is kind of damaged so using a tensioner in that spot isn't an option. My sprocket isn't concaved, and my wheel cannot be pulled more to one side or the brakes will not work.

I have the flat sprocket from bgf bike kit. I have to run two washers on the engine chain side or it rubs. I have coaster rear wheels so I can't speak to the brake issue. I run a 1.95 tire back there.
