Maxiis tire pressure
I have Maxiis radial M8008 load range D tires on our fifth wheel. The Rv loaded weighs around 8500 lb. Does anyone know what the psi should be?

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.
