I got a set of 5-rib Vredestein V61 tires and tubes for my 82s for $83 shipped from
www.tiresunlimited.com . From what I've heard, they're less likely to tear up your lawn than the 3-rib 'stones and have gotten rave reviews at the green site and across the street. Not to mention they're much cheaper. I can't wait to get home in May and mount them.
