Where do I find my size?

It's on the tire sidewall, e.g. P265/70R17 115T, and on the tire placard sticker on the driver's door jamb (also in the owner's manual). The placard shows the size the vehicle came with; the sidewall shows what is fitted now. If they differ, use the placard as your starting point. Digits are enough here: 2657017 or 33125020.

Figures from the makers' own data books. They differ from the 27.9 in calculated figure because each tread design and construction measures slightly differently.

FAQ

How tall is a 215/70R16 tire?

27.9 inches (707 mm) calculated from the size code. Makers publish 27.7–28 in for real tires in this size; the difference comes from tread design and construction.

How do you work out the 215/70R16 diameter?

Sidewall = 215 mm × 70% = 150.5 mm. Diameter = 16 in wheel + 2 × 150.5 mm ÷ 25.4 = 27.85 in.

Is 215/70R16 a 28-inch tire?

It is about 27.9 in tall nominally, so it is close to 28 inches. Real tires in a size vary slightly by model; check the maker's spec sheet for the exact tire.

What sizes are equivalent to 215/70R16?

Real sizes within 3% of its diameter include 345/40R17 (+0.1%), 315/40R18 (+0.3%) and 285/35R20 (±0.0%). Equal diameter alone doesn't make a size suitable: wheel width, offset, clearance and load rating all matter.

How many revolutions per mile does a 215/70R16 make?

About 724 calculated from its unloaded diameter. Makers publish 744–757 revs per mile, measured under load (a loaded tire rolls on a slightly smaller radius), which is why published figures are higher.

Important: These are calculated (nominal) dimensions, not a fitment recommendation. Real tires of the same size differ by brand and model (makers allow about ±3% of section height), and width changes with the rim it is mounted on. The math can't see wheel width and offset, clearance at full steering lock and suspension travel, load index, speed rating, or what your vehicle maker approves. Before changing size, check your door-jamb placard and owner's manual and ask a tire professional. A replacement tire must meet or exceed the load index and speed rating on the placard.
