Does the Dexstar Mini Mod Trailer Wheel # AM20539 Have a Max psi Capacity

Question:

Is there a limit to the air pressure for this wheel. Ive had friends tell me there are different wheels for low pressure trailer tires 65psi, vs high pressure E-load 80-110psi.

Wheels, like the Dexstar Wheel # AM20539 that you referenced, actually have a weight rating as opposed to a psi rating. Tires have a psi rating because it corresponds to the weight rating for the tire.

For example, the Kenda Karrier # AM10303 is a load range E tire meaning that it has a max load of 2,830 lbs at 80 psi. The aluminum wheel that you referenced, part # AM20539, has a weight capacity of 2,860 lbs. Since you will always be limited by your lowest rated component, if either of these weight ratings were lower and you were using this tire and wheel together then the combination would be limited to the lowest rated component.

Since they have different weight ratings if you were to use these together your weight capacity for the tire/wheel combo would be 2,830 lbs when the tire is inflated to 80 psi. The only part that you need to make sure is rated for the appropriate psi is the valve stem. For this application you will want to use part # AM20907 which is 1-1/4 inches long and is rated for up to 100 psi
