§ 1
Nominal measurements
By the formula 295/60R20 has an overall diameter of 33.9 in (862 mm), section width 11.6 in (295 mm) and sidewall height 7.0 in (177 mm).
Rim diameter is 20 in (508 mm), circumference 106.6 in (2,708 mm) and revolutions per mile 594 (369 per km). These are unloaded nominal numbers from the size math.
§ 2
What makers publish
Tire makers list 10 tires in 295/60R20 from 5 brands and all are LT versions; no P-metric passenger versions are listed. Makers list load range E for the entries and published overall diameters run from 33.9 in to 34.3 in, versus 33.94 in by the formula (−0.1% to +1.1%).
See the manufacturer tables for approved rim ranges and the maker-stated maximum loads.
- Firestone Destination X/T: 33.9 in diameter; weight 57.1 lbs; tread depth 16/32 in. (Firestone)
- Toyo Open Country A/T III: 33.9 in diameter; weight 60 lbs; tread depth 16.6/32 in; 612 revs per mile. (Toyo)

§ 3
Closest alternative sizes
Using a ±3% overall-diameter window (a tire-shop rule of thumb) the nearest sizes include 34x11.50R20 (+0.2%), 275/65R20 (+0.4%) and 285/60R20 (−1.4%).
Small diameter changes alter indicated speed, axle height and revolutions per mile. Use the page comparison tools such as the speedometer calculator or the size comparison for vehicle-specific checks.
- 34x11.50R20 (+0.2%): at an indicated 60 mph the true speed is 60.1 mph; axle height +0.03 in (+1 mm); revs 594 → 593.
- 275/65R20 (+0.4%): at an indicated 60 mph the true speed is 60.2 mph; axle height +0.07 in (+2 mm).
- 285/60R20 (−1.4%): at an indicated 60 mph the true speed is 59.2 mph; axle height −0.24 in (−6 mm); revs 594 → 603.

Note 1
P-metric or LT in the same size
10 LT and 0 P versions in the tables we read.
No single model in our tables is published in both P and LT versions of 295/60R20; Table 3 lists both types side by side.
On trucks and SUVs, the load ratings of the tires on an axle must add up to at least the axle’s GAWR on the certification label (49 CFR 571.110).
Vehicles on 295/60R20: not listed yet. We add a vehicle here only from its maker’s own spec sheet for that year and trim.
The size your vehicle left the factory on is printed on the tire and loading placard on the driver’s door jamb (49 CFR 571.110). Pressure and load: that placard too.

Q&A
Common questions
How big is 295/60R20 in inches?
By the formula it is 33.9 in (862 mm) overall and turns 594 revolutions per mile (369 per km); makers publish 33.9–34.3 in.
Are 295/60R20 tires LT or passenger?
Makers list the 295/60R20 entries as LT tires only; the published listings show load range E for the models checked.
Will the speedometer change with a different nearby size?
Yes. For example, replacing 295/60R20 with 275/65R20 (+0.4%) makes true speed 60.2 mph at an indicated 60 mph; switching to 285/60R20 (−1.4%) makes true speed 59.2 mph at an indicated 60 mph.
Where to find inflation and load info for a replacement tire?
See the tire and loading placard on the driver's door jamb for the vehicle maker's recommended cold inflation pressure and consult the tire sidewall for the maximum load rating and, for LT tires, the load range letter (49 CFR 571.110; 49 CFR 571.139).
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.
