When a used tire actually makes sense
If you’re comparing used tires in Amarillo against a new set, here’s the short version: a used tire can be a smart, safe choice for a low-mileage vehicle, a trailer that sits most of the year, or a same-day fix after a flat when the budget is tight, as long as it passes a real inspection first. It’s the wrong call for a tire that’s going to carry serious highway miles, and it’s a bad idea if nobody can tell you anything about the tire’s history. E&C carries both new and used tires and mounts them at your vehicle, so you’re not stuck guessing. Before you hand over cash for a used tire anywhere, here’s what actually matters.
Check the tread before anything else
Tread depth isn’t a matter of opinion. The National Highway Traffic Safety Administration says a tire is worn out and unsafe once the tread wears down to 2/32 of an inch, the point where the built-in tread wear indicators (the raised bars between the grooves) go flush with the surrounding tread. NHTSA’s own at-home check: put a penny in the tread groove with Lincoln’s head upside down, facing you. If you can see the top of his head, the tire needs to go. (Source: NHTSA, Tires | TireWise.)
On a used tire, don’t just check one spot. Wear should be even across the tread. Uneven wear is usually a sign of an alignment or suspension problem on the vehicle the tire came off of, and that’s not a problem you want to inherit along with the tire.
Age matters even when the tread looks fine
A tire can have plenty of tread left and still be dangerous to drive on. Rubber breaks down over time from heat and UV exposure, whether or not the tire has ever touched pavement. NHTSA notes that some vehicle and tire manufacturers recommend replacing tires that are six to ten years old, regardless of remaining tread. NHTSA also lists sunlight, warmer climates, poor storage, and infrequent use as factors in tire aging, and notes that aging is a bigger concern in the more southern parts of the Sun Belt states. A used tire that spent years sitting outside in the sun has been aging the whole time. (Source: NHTSA, Tires | TireWise.)
You can check a tire’s age yourself without asking anyone. Look on the sidewall for the DOT identification number. The last four digits are a date code: the first two digits are the week of the year, the last two are the year. NHTSA gives the example of a tire marked 0308, made in the third week of 2008. If a used tire’s date code puts it near or past that six-to-ten-year window, the price on the sticker doesn’t matter. Walk away.
This cuts against take-off spares too. Because tires degrade over time, NHTSA recommends not using a full-size spare as a replacement for worn tires, except in emergencies such as replacing a flat. A spare ages sitting in a trunk just like any other tire.
What a used tire is actually hiding
The U.S. Tire Manufacturers Association, the trade group representing tire makers, is blunt about this: “while new tires must meet stringent federal safety standards to be sold in the U.S., worn tires can be resold as used with virtually no restrictions.” Their conclusion is that reselling a used tire as a replacement is “a risky proposition for motorists.” (Source: USTMA, Used Tires.)
USTMA’s point isn’t about tread or price. It’s that nobody selling you a used tire can tell you, with any certainty, how it was used, whether it was stored properly, or whether it was ever run flat or repaired. And you can’t fully check for yourself either: USTMA notes that damage or improper repairs to a tire’s inner liner (the layer that holds the air) are only visible after the tire is demounted from the wheel, and even then it takes a qualified technician to make that call. A tire with a visible bulge, a lump, cracking anywhere in the sidewall, or a repair near the sidewall or shoulder is one to skip outright, no matter how good the tread looks from the outside.
Used tires and all-wheel-drive vehicles
If your vehicle is all-wheel drive, be careful about mixing a used tire with the other three. Many AWD systems are sensitive to tread depth differences between tires, and putting one noticeably more worn tire on a vehicle with three newer ones can put uneven load on the drivetrain. Check your owner’s manual before mixing tire ages or brands on an AWD vehicle, or ask us and we’ll tell you straight whether it’s a fit for your setup.
When to skip the used tire and go new
A used tire is a reasonable call for a low-mileage second vehicle, a trailer that sits most of the year, or getting back on the road same-day after a blowout on a tight budget. It’s the wrong call when:
- You’re about to put serious highway miles on the vehicle, especially in summer heat, since NHTSA counts warm climates among the factors in tire aging.
- The tire is a steer tire on a truck, where a failure carries more weight and more consequence.
- The seller can’t answer basic questions about where the tire came from or whether it’s ever been repaired.
How to buy a used tire without getting burned
Ask before you buy: how old is the tire, has it ever been repaired, and can it be inspected off the wheel before it goes on your vehicle. A legitimate seller won’t mind the questions. If nobody can answer them, that tells you something too.
E&C carries both new and used tires and mounts them wherever your vehicle is, across Amarillo and the surrounding Panhandle.
