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.

FAQ
How tall is a 215/55R17 tire?
26.3 inches (668 mm) calculated from the size code. Makers publish 26.1–26.6 in for real tires in this size; the difference comes from tread design and construction.
How do you work out the 215/55R17 diameter?
Sidewall = 215 mm × 55% = 118.2 mm. Diameter = 17 in wheel + 2 × 118.2 mm ÷ 25.4 = 26.31 in.
Is 215/55R17 a 26-inch tire?
It is about 26.3 in tall nominally, so it is close to 26 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 215/55R17?
Real sizes within 3% of its diameter include 215/60R16 (−0.6%), 235/45R18 (+0.1%) and 265/30R20 (−0.2%). 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 215/55R17 make?
About 767 calculated from its unloaded diameter. Makers publish 789–800 revs per mile, measured under load (a loaded tire rolls on a slightly smaller radius), which is why published figures are higher.
