Hey Olblu, I know a guy with a spare cooper you could borrow. Actually I got 2 of Bills old tires and 2 new 600 x 16 for the front. Yes they tend to follow the grove, but it it a lot easier to steer than with the radials I had on. Ran trucks for years with Bias tires, a little noisier than radial, but will go just as fast. And really how fast do you want to go with manual brakes and steering?
