The 255/60R17 is a common tire size for SUVs and crossovers such as Toyota RAV4, Honda CR-V, and Ford Explorer.
With a 153.0 mm sidewall (60% aspect ratio), this tire provides a smooth, cushioned ride that absorbs road imperfections well — ideal for daily commuting and highway cruising.
Compared to the baseline 225/50R17, this tire's overall diameter differs by +12.3% — a speedometer calibrated for 225/50R17 would read 89.0 km/h at an actual 100 km/h.
OE on the Jeep Grand Cherokee (WK 2005-2010), Ford Explorer (U251) and Cadillac SRX (2004-2009). Load index 106H or 110S reinforced. North-American mid-size SUV size with H-T and A-T compound availability.
Truck sizes here are often P-metric on lighter trims and LT-metric on tow-rated specifications — the difference matters. LT versions in load range D or E carry roughly 30-40% more vertical load and tolerate the off-axis stresses of bumper-pull towing. Verify the door-jamb placard for the originally specified construction; mixing P and LT on the same axle is dangerous and voids warranty on most pickups.
