235/55R18 tires
Every factory application of this size in our OE fitment data, the geometry behind it, and the staggered pairings it ships in.
235 = tread width in millimetres · 55 = sidewall height as a percentage of that width · R18 = radial construction on a 18-inch wheel. Two sizes with the same overall diameter are speedometer-compatible, that is the whole game in staggering.

Tire recalls are filed with NHTSA on random Tuesdays and nobody tells you. Park your car here and when a campaign names your platform’s sizes — or its fitment data changes — you get one email. That is the entire list: no newsletter, no promos, email + platform is all we store, and every alert carries an unsubscribe link.
