Closest sizes and changes
The neighbor table shows sizes within ±3% of 265/75R16's diameter. The ±3% window is a tire-shop rule of thumb, not a law. See the comparison tool for other neighbors.
Nearby sizes include 265/70R17 (31.6 in, −0.1%), 285/70R16 (31.7 in, +0.2%) and 235/85R16 (31.7 in, +0.2%). Examples of what changes:
- 265/70R17: diameter −0.1% (−0.04 in, −1 mm); indicated 60 mph reads about 59.9 mph; axle ground clearance −0.02 in (−1 mm); revs per mile 637 → 638.
- 285/70R16: diameter +0.2% (+0.06 in, +2 mm); indicated 60 mph reads about 60.1 mph; axle ground clearance +0.03 in (+1 mm); revs per mile 637 → 636.

Q&A
Common questions
How large is 265/75R16 in inches?
By the size formula the overall diameter is 31.6 in (804 mm); section width 10.4 in (265 mm); sidewall height 7.8 in (199 mm).
How many revolutions per mile does it make?
Nominal revolutions per mile are 637 (396 per km). Toyo lists 656 revs per mile for its Open Country A/T III in LT265/75R16.
What load ranges and markings are common?
Makers list SL and E load ranges in 265/75R16; many published tires are LT construction. The tire sidewall shows the maximum load rating and, for LT tires, the load range letter as required by 49 CFR 571.139 (FMVSS No. 139).
Will it change my speedometer reading?
Small changes in diameter change speedometer and clearance. For example, 285/70R16 is about +0.2% and would read about 60.1 mph when the speedometer indicates 60 mph.
Notes
Method and sources
Each number and rule comes from a source with the date it was checked.
- Sidewall = width × aspect ratio ÷ 100
- Diameter = rim × 25.4 + 2 × sidewall (mm)
- Revs per mile = 63,360 ÷ (π × diameter, in)
- True speed = dial × new diameter ÷ old diameter
- Clearance change = half the diameter change
Numbers are nominal: the tire unloaded, on its measuring rim. Revs per mile published by makers run higher than the formula. “Within 3%” is a rule of thumb tire shops use, not a law. Tire pressure: the placard on your door jamb.
