§ 1

Nominal measurements

By the formula 285/75R16 has overall diameter 32.8 in (834 mm), section width 11.2 in (285 mm), sidewall height 8.4 in (214 mm) and a 16 in (406 mm) rim. These are nominal, unloaded numbers calculated from section width and aspect ratio.

Circumference 103.1 in (2,620 mm) and 614 revolutions per mile (382 per km). See the cross-section drawing and the nominal size table for the geometry and measuring rim.

§ 2

Published measurements

Makers' published tables list 15 tires in 285/75R16 from five brands; all entries are LT versions and none are P-metric passenger in the tables checked October 15, 2026. Makers list load range E and publish approved rim widths as required by FMVSS No. 139.

Published diameters run 32.8–33.1 in versus the nominal 32.8 in. Published weights run 51.8–70.2 lbs and new tread depths run 15.8/32–20/32 in.

Closest sizes and effects

The neighbor table uses a ±3% overall-diameter window as a tire-shop rule of thumb, not a law. Use the neighbors table, the comparison tool or the speedometer calculator to see exact changes.

Nearby sizes include 305/70R16, 285/70R17 and 33x10.50R15. Small diameter differences change revs per mile, indicated speed and axle clearance by the amounts listed below.

305/70R16: diameter −0.1% (−0.02 in); indicated 60 mph → true 60.0 mph; revs per mile 614 → 615; axle clearance −0.01 in.
285/70R17: diameter −0.4% (−0.12 in); indicated 60 mph → true 59.8 mph; revs per mile 614 → 617; axle clearance −0.06 in.
33x10.50R15: diameter +0.5% (+0.17 in); indicated 60 mph → true 60.3 mph; revs per mile 614 → 611; axle clearance +0.08 in.

Note 1

P-metric or LT in the same size

15 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 285/75R16; 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 285/75R16: 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.

Q&A

Common questions

How big is 285/75R16 in inches?

By the formula overall diameter is 32.8 in (834 mm), section width 11.2 in (285 mm), sidewall 8.4 in (214 mm) and 614 revolutions per mile (382 per km).

Are 285/75R16 tires LT or P-metric?

Published size tables checked October 15, 2026 list 15 tires in 285/75R16 and all are LT versions; no P-metric passenger versions appear in those tables.

What load range and markings should I check?

Makers list load range E for 285/75R16. FMVSS No. 139 requires the sidewall to show the maximum load rating and, for LT tires, the load range letter.

Will a nearby size change my speedometer?

Yes. For example, 285/70R17 at −0.4% would make an indicated 60 mph read about 59.8 mph true. Use the site's speedometer calculator for other sizes.

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.
