What Size Rim for a 275 Tire?
Find the minimum, ideal, and maximum safe wheel rim width required to support any 275 series tire.
Quick Answer
For a 275mm wide tire, the manufacturer-approved rim width range is typically between 7.5 and 9.5 inches. If you are mounting a common full-size truck tire like a 275/60R20, using an 8.5-inch or 9.0-inch wide wheel is the absolute best fitment for tread longevity.

Rim Fitment for Popular 275 Tire Sizes
| Tire Size | Minimum Rim | Ideal Rim | Maximum Rim |
|---|---|---|---|
| 275/70R18 | 7.0" | 8.0" | 8.5" |
| 275/65R18 | 7.5" | 8.0" | 9.0" |
| 275/60R20 | 7.5" | 8.0" – 8.5" | 9.5" |
| 275/55R20 | 7.5" | 8.5" | 9.5" |
| 275/45R22 | 8.5" | 9.0" | 10.5" |
| 275/35R20 | 9.0" | 9.5" | 11.0" (low profile requires wider rim) |
Formula
275mm ÷ 25.4 = 10.82" wide | Ideal Rim = 10.82 × 0.85 = 9.19"
- Ideal target = 9.0 inches for most 275 truck and SUV applications
- Tall off-road tires (like 275/70) can safely use narrower 7.0–8.0 inch rims
- Low-profile sport tires (like 275/35) require wider 9.0+ inch rims
- Best all-around choice for 275/60R20: 8.5-inch rim
