If you don't have immediate access to compressed nitrogen, you can certainly add compressed air to the tire to bring it up to the correct pressure. Compressed air works just fine (atmospheric air is about 78% nitrogen) folks have been using it to till tires for a hundred years and it won't have any negative effect on the tires if the two or mixed.

The primary benefit of nitrogen is that the pressure in the tire will bleed out more slowly than compressed air does. Properly inflated tires mean less rolling resistance which means better fuel economy for the tow vehicle and longer tire life. This benefit isn't terribly important if you're pretty fastidious about keeping tabs on your tire pressure or if you use a TPMS system like # TST-507-RV-4-C.

If you're like the majority of us that do an imperfect job of monitoring your tire pressures, it might be worth it to take your toy hauler to a shop that can deflate your tires and refill them with nitrogen.

Answer 1

I can end this debate for you real fast! Trailer tires, which will have an ST in front of the size, should always be inflated to the maximum psi indicated on the tire. Trailer tires usually do not have a recommended and maximum psi indication so I am…

Load range B trailer tires are going to have a lower capacity than C load range tires. Basically that, psi rating, and the ply rating are the only differences. A higher load range tire would last a little longer than lower load ranges of the same…

Hey Austin, For a 5.70-8 tire size on with a 4 on 4 bolt pattern we offer a Load Range D, but don't have a higher speed rating than K (65mph). To get the increased speed rating you'd need to go to a larger size tire like 215/60-8, which would…

Answer 5

In order to find the correct tires for your trailer, we will also want to take wheel bolt pattern into consideration. All of the 5.70-8 size tires that we carry have either a 4 on 4 bolt pattern or a 5 on 4-1/2 pattern. I have attached a help article…

Answer 6

On a towing setup you are always limited by the lowest rated component as the overall towing capacity since that is the weakest point. When it comes to trailer tires you always want to have them inflated to their max psi when cold. Not only do you…

Answer 8

The 5.70-8 tire size is about the largest diameter tire available for an 8 inch rim. Your current tire is about 18 inches in diameter and has a tread width of 5.9 inches. A 215/60-8 tire is about the same diameter, but has a wider tread width at 8.9…
