  1. Thanks to all for your input. I've ordered the larger tires and will find out out if there is any fender or wheel well rubbing and will see if the speedometer error is improved. I'll warn everyone if there are consequences. However, I'm no race car driver and doubt that I'll be able to discern slight changes at the limits of cornering. My usual comment is that my car is more of a parade float than a race car. It is a tip cab after all. :)
