80 PSI on Aluminum Wheels

I would just buy from a manufacturer that makes a tire in the size/rating needed. There are several new style, cooler running, higher speed rated tires out there, that have been time proven, with good reviews. My FW came with 225/75/15 D rated Provider tires. They have been a great newer designed ST tire, with excellent reviews. Another choice, Carlisle HD. Both are good choices, available in your size, and D rating, at a better price than the GYs.

If you want the E rated GY tires, they seem to be getting good reviews from some early owners. Time will tell, I hope they will prove to be a quality ST.

You should pull off 1 of your tire/wheel assemblies.. Once off, look on the back of the wheel, possibly near the center for a stamp... MOST, if not ALL wheels will have a weight rating stamped into it that will tell you the rating...

Would this cause more sidewall flex and less stability? Granted this is a FW.
Any concern in a sharp turn being underinflated?

Check with KZ and see if they can give you the rating for the rims they put on. With my old Jayco they gave me the rim manufacturer and I checked with them before using E rated tires. Mine were alright.
