I can't be the only one with this problem!!
The cruiser has a 26x2.125 size tire.... I cannot get the drive chain to stop rubbing the sidewall?? Please help.....
 
It's more important to have the chain run straight, so look down the chain and make sure the sprocket is on the right way around so it does.
You can run a thinner (1.95) tire.
 
i had the same problem i ended up puttin two bolts on the axle on the left side where your sprocket is in between the frame and the coaster brake, then mounted the tire on making sure it was straight, then i bolted the wheel down on the frame, and saw the chain was straight, but to be honest idk if what i did was good, i think it causes tire wear, so maybe you want to try to tightening the chain a bit more
 
the chain rubs on all my bikes. as long as it's not actually cutting into the tire, ya just gotta live with it.
 
I actually have the wheel kicked to the right a touch to help clear.. Although now the sprocket is not perfectly aligned... I will try the narrower tire.
 
it's important to keep your sprockat aligned with the drive sprocket on the engine, you see my teacher at my automotive school builds race bikes and he gave me a tip, to take a laser an see if the chain is aligned straight, if not your chain will pop off, so to keep your chain straight nd to keep your tire from wearing or cutting slightly just go with a thin tire,
 
Thanks for the tip... I think the thinner tire will do it... Ordered a 26x1.75 whitewall... How do I post pics ? It's a sweet looking rat !!
 
find a hub adapter, you can adjust how far in or out the sprocket is, smoother and safer. you can also change different size sprockets on the fly.
