I recently had a couple of old tires replaced on my 3 horse steel GN. I was airing up the tires and noticed 3 of my tires require 80 PSI and the fourth takes 65 PSI. IS this a problem and do I need to replace the 65 psi tire with an 80 psi tire?

The ones that hold more air are a heavier load range and stiffer. The 65psi may not be rated high enough to carry your load and may effect handeling with less air and weight distribution

Actually the trailer calls for 65 PSI on the silver tag. These tires were ordered by a friend who owns his own mechanic car care business without him looking at the tag first. They are Carlisle trailer tires rated for 80 PSI. I hate to have to buy another tire if I don't have too but I would really hate a blow out.

look on your silver tag for the tire size and load range rating, if you have tires rated above that you're better off. just keep your tire pressures ALL the same for safety reasons

So the 80 Psi tires should be at 65? Will running 80 PSI tires at 65 cause sidewall strain and heat build up? Sorry, I'm a girl and none of the men in my life have a clue about this....

Be very careful with the Carlisle tires. In this and other forums, they have a poor reputation for frequent blow outs. I would use the D range tire (65 PSi) as a spare and purchase an additional E range tire (80 PSI) to replace it.
Be very careful of your speeds, tire pressures and trailer loading, to minimize the chances of tire failures with this brand. When they do fail, replace them with an American made, truck E range LT tire.
