To improve the roadholding, handling, and performance of your vehicle, we recommend that you mount four identical or similar tires. If your tires are not identical, one of the axles may not respond as rapidly or in the same way as the other, which would make it difficult to control all parts of the vehicle.
If your tires are only minimally worn (the main tread pattern still has maximal groove depth) but you need to change a flat tire or one damaged by an accident, it is very important that the replacement be the same type of tire. The new tire must be the same brand and have the same specifications as the first. It must also have the same speed/load indexes, the same profile/construction, and, of course, the same dimensions.
If two tires have a maximal degree of wear or are damaged, you must replace them with identical or similar tires. It is very important that you select tires having the same characteristics as those already mounted on your vehicle.
It is a good idea to mount new tires (or those with the least wear) in back instead of in front. The driver has little or no control over loss of rear wheel grip. By mounting new tires in the back, grip is balanced between the two axles, which improves safety. Despite weak grip, the driver controls the front axle with the steering wheel, while the rear axle grip is optimised by the new tires.
When two new tires are mounted on your vehicle, don't hesitate to ask your mechanic why the tires on one axle wore faster than those on the other. This could be due to bad alignment or incorrect geometry (click here for more details).
At Tires & Co, we advise against waiting until your tires reach their wear limit. Rain will increase the chances of aquaplaning starting at 0.07 inches or at 0.11 inches for wider tires.
If all four tires become worn at the same time, you have more flexibility in the selection of new tires. If you are satisfied with your old tires, you can purchase the same kind. Or if you wish to change to another profile or brand, you will obviously need to be sure that these tires suit your vehicle. You can then select tires that are more comfortable and offer better performance and higher endurance. Choose according to your driving style and the characteristics you are looking for, and always follow the recommendations of your vehicle manufacturer, including homologation guidelines.
Once you know how many tires to change, you must determine the size and type of tires you are looking for.
If you feel that the best tire for your vehicle is too expensive compared to another brand, don't forget that tire price is a function of other criteria such as tread wear, performance, comfort, quality, etc. How much will you save per mile with less expensive tires?
If you plan to travel 20,000 miles with tires that cost $13 more than the tire best suited to your vehicle, you might be surprised to learn that price difference per mile is $0.0003. Does this difference justify buying a tire that is perhaps less suitable?
