Seriously, how much force are you using to set the roller to the tire? They need to be snug. Don't worry about compressing the tire a little. It won't hurt anything.
My friction drive is a wooden roller 3.5" diameter pressed to the tire by the weight of the 79cc engine.

But since I began writing this post, I moved my gas tank to the front of the bike. The pic above is it. (It's a shot at a distance & cropped.)
This will reduce the weight even more, but I'm thinking on using a spring arrangement rather than what I have.
