Maxiis tire pressure

I run my Maxxis 16" tires at 10 under max psi, one reason because I have more tire than came on the RV and 2, because pres increases as you start rolling down the road so in hot weather they still sometimes get over the max pres but not enough to worry about.

The maximum pressure shown on the sidewall is the maximum COLD inflation pressure. The manufacturers know that the pressure will rise above this max pressure as temperature increases - that's allowed for in the rating. The 17.5" Goodyear G114 tires on our 5th wheel will go from a cold pressure of 120 PSIG to a "hot" pressure of 135-145 PSIG with a tire temperature of only 95 to 105 degF.

And even that cold pressure is not the maximum cold pressure of the tire. Its the cold pressure needed for the maximum load up to maximum speed of tire , or if lower 99m/h.
Once determined by info of tire maker semperit ( continental) that the maximum pressure cold is 1.4 times the AT-pressure given on sidewall ( fi D-load 65 psi x1.4=91 psi). Warm this rises 10 to 30% and tiretests by tire makers even fill 2 to 3 times the AT-pressure ( dont try this at home)
For ST tires most tire manufacturers still allow 10 psi higher then ( cold) AT-pressure.
This will not say that this AT pressure is always needed.

But I suspect the American tire makers of putting a tire designed for instance D-load in the market as E-load.
This I make of that in Europe there is much less choice in Loadrating.
