I got my 600-16 Firestone WWW's from Universal tire in Hershey. They installed on my rims and balanced them for me. The tires run well, with no shaking or balancing issues. My wife and I did a little vacation trip from Northern Ontario to Hershey to get the tires, which earned me bonus points from my wife.
