Can I Determine the psi Rating of a Wheel  

Question:

I have Goodyear G614 tires ST235/85/R16 with a 110 lb pressure . How do I determine if my steel rims are capable of handling thus pressure?

Since wheels will be able to withstand the psi rating of any of the tires that are meant to fit it you will need to look at the valve stem as that is the deciding factor.

If your valve stem has the rubber all the way up to the threads, like part # AM20903, then it will be rated around 65 psi. If there is some reinforcement between the rubber and the threads, like part # AM20904 or # AM20907, then your valve stem can be rated between 80 and 100 psi. The only valve stems that are rated for more than 100 psi are metal ones like part # AM20906. If your wheels do not have metal valve stems then they will not be able to hold the pressure of 110 psi that you require.

Ultimately unless you bought the wheel from us and can give me the part number then the best way to know what the psi rating of your wheel (or valve stem rather) is would be to call the manufacturer.

So if I upgrade the valve stems on my 15 inch metal boat tralier wheels I can put 110 psi tires on them?

Correct - that shouldn't be a problem at all. You'll want to add metal valve stems like # AM20906.

What will happen if my tire mechanic uses both grommets on the screw type vale stem , one inside and one outside ?

I'm not sure why both grommets would be used. I honestly would just use the size appropriate for the hole on your rims to avoid any potential issues.
