Could a ST205/75R15 Load Range C be Replaced with a ST215/75R15 Load Range D

Question:

My trailer currently uses SenDel T02-56545T wheels with ST205/75R15 load range C tires. As weighed on truck scales, the axles carry 3,000 pounds each. I would like to upgrade to your tires #TR20515D Taskmaster Provider ST205/75R15 Radial Tire - LR D *OR* your tires #TR22515 Task Master ST225/75R15 Radial Tire - LR D I have the clearance for the larger tire, but according to the SenDel web site, the maximum inflation pressure for my wheels is 60PSI. Can I safely use the TR22515 Task Master ST225/75R15 Radial Tire - LR D on these wheels? Thanks in advance,

Typically the limiting factor for trailer tire pressure is the valve stem. The Taskmaster Tire part # TTWTRTM2257515D you are interested in has a 65 psi max rating which should be just fine with your rims as long as you go with similarly rated valve stems.
