§ 1

What the size measures

By the formula 315/75R16 is 34.6 in (879 mm) overall. Section width is 12.4 in (315 mm). Sidewall height is 9.3 in (236 mm) on a 16 in (406 mm) rim. Circumference is 108.7 in (2,761 mm).

Revolutions by the formula are 583 per mile (362 per km). These are nominal, unloaded numbers calculated with standard tire math.

  • Formula used: sidewall = section width × aspect ratio / 100; overall = rim × 25.4 mm + 2 × sidewall.
  • Revs per mile formula: 63,360 / (π × diameter in inches).

§ 2

What makers publish

Makers' size tables list 11 tires in 315/75R16 from 5 brands. All 11 entries are LT tires; none are P-metric passenger versions. The listed load range for those LT entries is E (maker tables).

Published overall diameters run 34.5 in to 34.96 in versus 34.60 in by the formula (−0.3% to +1.0%). Weights run from 64 lbs to 82.4 lbs. New tread depths run from 16.3/32 in to 21/32 in.

  • Toyo Open Country A/T III: 34.6 in overall; 12.3 in inflated width; 65 lbs; 16.9/32 in tread; Toyo lists 601 revs/mi.
  • Nitto Ridge Grappler: 34.57 in overall; 12.32 in inflated width; 73 lbs; 16.4/32 in tread.
  • Kumho Road Venture MT71: 34.8 in overall; 12.3 in measured width; 77.5 lbs; 20/32 in tread.

§ 3

Closest sizes and changes

Neighbors within ±3% of 315/75R16's diameter are calculated on rims from 15 to 17 in. The ±3% window is a tire-shop rule of thumb, not a law. See the comparison tool for more pairs.

Examples show how small diameter changes affect indicated speed, revs and axle clearance. Use the speedometer calculator for exact indicated-to-true speed differences.

  • 315/75R16 → 295/75R17: diameter −0.5% (−0.18 in, −5 mm); at an indicated 60 mph true speed is 59.7 mph (100 km/h → 99.5 km/h); revs 583 → 586; axle clearance −0.09 in (−2 mm).
  • 315/75R16 → 315/70R17: diameter −0.7% (−0.24 in, −6 mm); at an indicated 60 mph true speed is 59.6 mph (100 km/h → 99.3 km/h); revs 583 → 587; axle clearance −0.12 in (−3 mm).
  • 315/75R16 → 35x10.50R17: diameter +1.1% (+0.40 in, +10 mm); at an indicated 60 mph true speed is 60.7 mph (100 km/h → 101.1 km/h); revs 583 → 576; axle clearance +0.20 in (+5 mm).

Note 1

P-metric or LT in the same size

11 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 315/75R16; 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 315/75R16: 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.

How tall is a 315/75R16 tire?

By the formula it is 34.6 in (879 mm) overall. Maker measurements run 34.5 in to 34.96 in.

How many revolutions per mile does it make?

By the formula it makes 583 revolutions per mile (362 per km). Toyo lists 601 revs per mile for its Open Country A/T III in this size.

Is 315/75R16 an LT or P size?

Where do I find the vehicle's tire pressure and load info?

The tire and loading placard is on the driver's side B-pillar (door jamb). See that placard for the vehicle maker's recommended cold inflation pressure and load limits (49 CFR 571.110).

Notes

Method and sources

Each number and rule comes from a source with the date it was checked.

  1. Sidewall = width × aspect ratio ÷ 100
  2. Diameter = rim × 25.4 + 2 × sidewall (mm)
  3. Revs per mile = 63,360 ÷ (π × diameter, in)
  4. True speed = dial × new diameter ÷ old diameter
  5. 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.
