The 265/70R17 is a common tire size for trucks and large SUVs such as Toyota 4Runner, Jeep Wrangler, and Ford F-150.
With a 185.5 mm sidewall (70% 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 +22.2% — a speedometer calibrated for 225/50R17 would read 81.8 km/h at an actual 100 km/h.
OE on the Toyota 4Runner (N280) SR5/TRD Off-Road/TRD Pro and Toyota Tacoma (N300) TRD Off-Road. Load index 113S or 121S in LT load range E. Aggressive A-T tread availability is the deepest at this size — virtually every off-road brand (BFG K02, Falken Wildpeak, Wrangler Duratrac) offers it.
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.
