How much air pressure are you running in your tires? On my '32, I run 25 lbs in the fronts and 20 lbs in the rears. I found this amount gives the tread a full contact patch with the road. You can use some powdered chalk from a chalk string, mark you tires, and drive over some paper to determine if your tires are making a full contact patch with the road. That way you can figure out how much air pressure to run in your tires. Our deuces are pretty light in the rear, and 30-35 pounds in the rear tires is actually over-inflating them.
