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 195/50R15 tire?
22.7 inches (576 mm) calculated from the size code. Makers publish 22.7–22.8 in for real tires in this size; the difference comes from tread design and construction.
How do you work out the 195/50R15 diameter?
Sidewall = 195 mm × 50% = 97.5 mm. Diameter = 15 in wheel + 2 × 97.5 mm ÷ 25.4 = 22.68 in.
Is 195/50R15 a 23-inch tire?
It is about 22.7 in tall nominally, so it is close to 23 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 195/50R15?
Real sizes within 3% of its diameter include 205/40R16 (−1.0%) and 215/35R17 (+1.1%). 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 195/50R15 make?
About 889 calculated from its unloaded diameter. Makers publish 910–921 revs per mile, measured under load (a loaded tire rolls on a slightly smaller radius), which is why published figures are higher.
