OUR 40,000 MILE GUARANTEE The Radial V-1 is guaranteed to give you 40,000 miles of treadwear in normal passenger use on the same car. If it doesn't, take your guarantee to any Firestone Store or participating Dealer. He'll replace the tire with a new one and give you credit at the current exchange price plus Federal excise tax for the mileage not re ceived (a small service charge may be added). Tires must be inspected and rotated by us (free!) every 5,000 miles and car properly maintained. OUR 7 DAY TEST RIDE You've probably heard that radials give you better hand ling, cornering, steering, traction, and wear than other tires, but that they ride a little rougher. Not Firestone's new Radial V-1. To prove it, we say this: Trade in your old tires on a set of Firestone Radial V-1's. Drive on them for seven days. If you don't like the way they handle-or ride-return them to your Firestone Dealer or Store within seven days and we'll put your old tires on again and refund your money. In full.
