Tire questions
My trailer tires ST205/75R14 say max load at 50 PSI, the trailer sticker says max psi 50. The wheels (Sendel machined aluminum are max 60 PSI). The new Goodyear Endurance trailer tires are max load ...

Tires and wheels have max load and pressure ratings for a reason.
If your wheels don't have a load or presure rating then contact the wheel maker...not a tire mfg.

2. WHEELS & TIres -
Wheels and tires must be matched. The wheel will have a label stating its rim diameter, width and contour. The tire selected must be approved by the Tire and Rim Association for use on that particular size wheel. The tire capacity selected should not exceed the capacity rating of the wheel. The tire inflation pressure must not exceed the pressure rating of the wheel. WARNING - The use of tires that are not approved for use on a wheel could result in explosive separation of the tire and wheel and could cause a serious accident.

RIM SELECTION
LOADS AND INFLATIONS FOR RIMS AND WHEELS
IMPORTANT — Rim dimensions are standardized by The Tire and Rim Association for size and contour only, and particular tire and rim combinations are designated to assure proper mounting and fit of the tire to the rim. The load and cold inflation pressure imposed on the rim and wheel must not exceed the rim and wheel manufacturer’s recommendations even though the tire may be approved for a higher load or inflation. Rims and wheels may be identified (stamped) with a maximum load and maximum cold inflation rating. For rims and wheels not so identified or for service conditions exceeding the rated capacities, consult the rim and wheel manufacturer to determine rim and wheel capacities for the intended service.
