Grade A vs Grade B used tires
In the wholesale used tire trade, the "grade" sums up how much tread each tire has left. It is not an official standard: every supplier sets its own cut-offs. What matters is knowing how your supplier measures and where each grade starts and ends. This is how we do it.
Grade A and Grade B in numbers
| Grade A | Grade B | |
|---|---|---|
| Tread depth (32nds of an inch) | 8–9/32" | 6–7/32" |
| Tread depth (millimetres) | 6.35–7.14 mm | 4.76–5.56 mm |
| How it is measured | Digital tread gauge, tire by tire, before it is graded. | |
| Tire type | Passenger tires, premium brands, in the best-selling sizes. | |
Which grade is right for you?
With more tread, Grade A lasts longer on the end customer's car, so it sells at a better price with fewer complaints. It is the usual choice when your customers compare against new tires.
Lower cost per unit makes Grade B move fast in markets where buyers look mainly at price. Many importers use it to have an entry price at the counter.
