Do my new tires require any special treatment? Your new tires will probably feel different from the tires that were replaced. Drive carefully as you become familiar with their performance and handling. Take special care when braking, accelerating, cornering, or when driving in the rain, because these are the times when the differences will be most noticeable. How long should my original equipment tires last? Goodyear does not offer a written mileage promise on any tires supplied as original equipment. Due to the variety of styles, construction features, treat compounds, vehicle applications, geographical conditions and driving habits, it is difficult to provide a specific mileage expectancy. However, any tire wear concern should always be presented to your local authorized Goodyear retailer for further evaluation. Many of our authorized retailers offer specific mileage warranties on several lines of tires sold as replacement tires, including some tires that are used as original equipment. These mileage warranties are administered based on the retail outlets verification of proper tire maintenance having been performed. Isn't it easy to mount a tire on a wheel? Can't I do it myself? Never try to mount your own tires. Tire mounting is a job for the people who have the proper equipment and experience. If you try to do it yourself, you run the risk of serious injury to yourself as well as possible damage to the tire and rim. Must I replace my present tires with the same size tires? Never choose a smaller size than those that came with the car. Tires should always be replaced with the same size designation -- or approved options -- as recommended by the vehicle manufacturer or Goodyear retailer. Should I "mix" tire types on my car? Tires of different size designations, constructions, and stages of wear may affect vehicle handling and stability. For best all-around performance, it is recommended that all tires be of the same size, construction (radial,non-radial) and speed rating. If tires of different speed ratings are mounted on a vehicle, the same size, type and speed ratings need to be placed on the same axle, the tires with the lower speed rating will be the determining factor for permissible tire related vehicle speed. Never mix radial and bias-ply tires on the same axle. Get specific information from your Goodyear retailer. When buying just two new tires, should they be put on the front or rear? When radial tires are used with bias or bias belted tires on the same car, the radials must always be placed on the rear axle. Never mix radial and bias-ply tires on the same axle. When you select a pair of replacement tires in the same size and construction as those on the car, we recommend you put them on the rear axle. A single new tire should be paired on the rear axle with the tire having the most tread depth of the other three. Where can I find old production or discontinued tires for my classic or restored vehicle? Recently discontinued tires are quickly consolidated and sold in large quantities to several sources and Goodyear would have no method of tracking the inventory after this sale. Much older tires such as the older bias ply tires can many times be found through Kelsey Tire, Inc. in Camdenton MO. They have obtained the molds for several of these older bias ply tires. They can be reached at (314) 346-2506. For more information you can call (800) 325-0091. Another source may be Coker Tire in Chattanooga, TN. They can be reached at (800) 251-6336. Where can I get specific technical information or testing data about a Goodyear tire? All engineering data available to the public is provided on the respective product information brochure made available at the retail outlets or on the Goodyear website. Most technical or test data is considered proprietary and not available to the public. In some cases, some information may be shared but these inquires must be made in writing and mailed specifically to our Technical Center for review. |
