Recommended Tires For 2015 Jayco 38 FLFS Trailer.


I have had two blow outs with tire size ST235/80R 16 Load E Tires and yes, they were inflated to Max cold PSI of 80. One was a 75mph and the other at 60mph. I have a 2015 Jayco 38 FLFS and want to know if I can replace the factory tires with 235/85R 16 Load Factor F or G Tires? There is space to accommodate the larger tire relative to the trailer but I am not certain of the space between the tires.

For that load capacity of F or G, you would need to go with ST 235/85R16 tires as you stated and they have an outer diameter of 31.73 inches compared to the 30.79 inch diameter of the ST235/80R16 tires. They have the same section width, and fit the same wheels, so as long as your wheels have the room for the extra .94 inch between them you will be fine with the upgrade in size. If you upgrade, the tires will all need to be upgraded at the same time for safety and eliminating uneven wear.

For these larger tires with higher load capacity, I recommend the Taskmaster Provider ST235/85R16 Radial Trailer Tire - Load Range G # TTWPRG235R16. These have a speed rating of 75 mph max and a capacity of 4080 lbs at 110 psi cold. This may require you to upgrade your valve stems to the Americana Metal, Bolt-In Valve Stem - 1-1/4" Long - Over 100 psi # AM20906.
