295/30R20 tires

Every factory application of this size in our OE fitment data, the geometry behind it, and the staggered pairings it ships in.

FIG. 02· what 295/30R20 actually means
wheel · 20″ 295 mm section width 30% of width = 88 mm ∅ 27.0″ overall
Overall diameter27.0″Sidewall88 mmRevs/mile ≈748

295 = tread width in millimetres · 30 = sidewall height as a percentage of that width · R20 = radial construction on a 20-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.
