Milestar Patagonia X/T LT305/55R20 Tire
This LT305/55R20 X/T is the F/12-rated version. That detail belongs in the fitment conversation before the first tire gets mounted.
The X/T uses supported tread blocks and stone ejectors to suit mixed road and trail work. This LT305/55R20 version carries a 125/122Q service description, Load Range F and a 12-ply rating. Its approved wheel-width range is 8.50–11.00 inches. Match tire capacity, wheel dimensions and vehicle clearance together. A familiar size label alone does not establish fitment.

Fitment & Installation
Confirm the complete size, load index, speed rating and wheel-width range for the vehicle and load. Check body, suspension and brake clearance before mounting. Have a qualified installer set the correct cold inflation pressure. The catalog maximum pressure is a rated limit, not an everyday inflation recommendation. Ply rating describes load capability, not a count of actual sidewall plies.
