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). If your current tires aren't the original size, the placard shows what the vehicle came with. Digits are enough here: 2657017 or 33125020.

FAQ
How tall is a 265/70R17 tire?
31.6 inches (803 mm) calculated from the size code. Makers publish 31.5–32 in for real tires in this size; the difference comes from tread design and construction.
How do you work out the 265/70R17 diameter?
Sidewall = 265 mm × 70% = 185.5 mm. Diameter = 17 in wheel + 2 × 185.5 mm ÷ 25.4 = 31.61 in.
Is 265/70R17 a 32-inch tire?
It is about 31.6 in tall nominally, so it is close to 32 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 265/70R17?
Real sizes within 3% of its diameter include 265/75R16 (+0.1%), 265/65R18 (−0.1%) and 245/60R20 (−0.1%). 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 265/70R17 make?
About 638 calculated from its unloaded diameter. Makers publish 648–672 revs per mile, measured under load (a loaded tire rolls on a slightly smaller radius), which is why published figures are higher.
