Question:

I just ordered Taskmaster 4.80R12 Radial Trailer Tires for my light weight utility trailer. I never haul over 1000 lbs. Most of the time less. Should I always inflate to the maxium air presssure of 90 psi?

With trailer tires like the Taskmaster 4.80R12 tire part # TT48012C that you referenced you always need to keep them inflated to the max tire pressure to ensure you get the best tire wear, longevity, and ensure you have full weight capacity. Even if the full weight capacity isn't needed.

This tire needs 90 psi at all times. It's best to inflate the tire when cold, or not hot from being on the road.

The 12 inch tires that we carry are rated for 65 miles per hour. Any faster than that for extended periods and the excessive heat build up will cause tire failure. To get a tire with a higher speed rating you would have to go up in size. That also…
