About 245/55R18 tires
A 245/55R18 keeps a usable sidewall under the wheel, which is what most people actually want out of a daily setup. A tire size only means something next to a wheel width and a car, because the wheel decides what'll mount and the car decides what'll fit.
Tell us the car and the wheel set and you'll only see the 245/55R18 lines that mount and fit.
Common questions
- What does 245/55R18 mean?
- Width first, then sidewall, then the wheel it goes on. The tread's 245 mm across, and the sidewall is 55 percent of that. The R just means it's a radial, like everything else on the road now. Stood next to a tape it's about 28.6 inches tall.
- Will 245/55R18 fit your car?
- Tell us the year, make and model and you'll only see sizes that suit it. The wheel has to be wide enough to carry the tread, and the overall height has to stay near where the car started.
- What wheel width fits 245/55R18?
- It's a range, not one number. Anything from about 6 to 9.5 inches wide will take it, and every product page shows what that line's maker approves. Pick a wheel set first and the sizes narrow to it.
