My question is will the wheels handle the pressure after heating up on the highway? The old tires were 10 plys with a max pressure of 80 lbs. I'm not sure if that rating on the wheels is a cold pressure with allowances for the pressure rising when hot or should I reduce the tire pressure to 80 lbs? I don't want to damage the tires by running low pressure.
FORGET THE RATING OF THE TIRE! All that matters is that you have a higher rated tire than stock.
You still want to put the pressure in those new tires as stated on your RV’s sticker. All you have now is added insurance “peace of mind” on weight and speed ratings!
I changed over to Goodyear Endurance immediately upon bringing my new RV home. 14 ply instead of 10, 87 MPH rated instead of ...60(?) and half again the weight rating at full pressure BUT I DO NOT NEED THAT FULL PRESSURE. I need the pressure rated for my RV’s weight, that is all.
So now my tires will FLY at 70 MPH in the middle of the Arizona summer and I will not have a care in the world...until my next stop when I check them all! ALWAYS!
Max pressure will give your rig an extra 1 -2 points harder/harsher ride on the Richter scale is all you will accomplish. Instead of a 3.5 earthquake rolling down the road, you might attain a 5+! Look that up!
