Thanks,
At this point I am just trying to get some different tires as the ones currently on it are old, dry rotted and apparently the wrong size! I'm not doing anything crazy with it for the time being so i am going to go with these from Walmart. They don't have very deep ribs but think they will be okay for the price. Plus I work for walmart so get a discount, $50 for a pair with free shipping is hard to beat.
