To compare prices on used tires correctly, consider the tire tread depth, age of the tires, and all the patches and defects there may be on used tires, as tires with not very good characteristics should cost less than used tires in a good condition. The uniform tire quality grade standards, or UTQG rating, price of new identical tires, tire brand and the amount of wear are also important to consider when comparing tire prices.
Tire tread depth indicates how much longer you are going to be able to use preowned tires. The best way to evaluate this value is by using a cheap tire depth gauge. The more tread depth is left, the higher the price of the tire should be. It may not be a good idea to buy tires that have less than 4/32nds of tread.
It is best to change tires every five to six years, even if they have a lot of tread depth, so it may not be worth it to buy tires with the age close to that value. The writing on the side of the tire should help you to determine the age of the tire. If the tire has patches and defects, its price should be significantly lower than the price of a tire in a good condition. It is not a good idea to buy tires that have bubbles in the sidewalls.
Tires with a high UTQG rating should cost more than tires with a lower rating. The rating usually varies from less than 100 to 600. The rating of 600 indicates that the tires are extremely durable and firm.
