The 275/65R17 is a common tire size for trucks and large SUVs such as Toyota 4Runner, Jeep Wrangler, and Ford F-150.
With a 178.8 mm sidewall (65% 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 +20.2% — a speedometer calibrated for 225/50R17 would read 83.2 km/h at an actual 100 km/h.
A heavy-duty full-size pickup and large SUV fitment, more common in LT-metric load range C-E than as a passenger-car-rated stock size — modern full-size pickup OE typically uses 18" or 20" rim packages. Load index 115T or 121S in LT load range E. Wide 275 mm footprint adds dry-traction confidence for towing-rated trims and aftermarket off-road builds.
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.
