These ST175/80R13 tires have the GlobalTrax WR089 which is a tread pattern that evenly distributes load and disperses heat. Moisture resistant rubber used by GlobalTrax extends the tire life and reduces pre-mature dry rotting and cracking. The reinforced sidewalls ensure a cool, long lasting tire.
This 8-ply tire has a load rating of 1610 lbs. when fully inflated to its max PSI of 65. It is recommended to run trailer tires at their max PSI as that is what they are tested at for ratings and running them lower could cause tread wear issues or even a possible blow out.
All GlobalTrax tires come with a manufacture warranty for three (3) years from the date of manufacture of two (2) years form the date of purchase, whichever comes first. This warranty covers defects due to defective materials and workmanship.
