It is also written as 235\/85R16 or 235\/85-16 and measures about 31.7 inches tall and 9.3 inches wide. The 85 series sidewall is about an inch taller than a 235\/80R16 and carries more weight.\u003c\/p\u003e\u003cp\u003eWe carry it in load range E (10-ply, about 3,640 lbs per tire) and load range G (14-ply, about 3,900 lbs per tire), all radial, including the Goodyear Endurance. Match the load range on your current tire or the trailer's capacity sticker, and never go lower.
