I have been totally unable to get 4 corner weights where I am..When I picked up the coach from the dealer, the walkthru mechanic said to put 115 front, 85 in the drive and 65 in the tags...I know all about weight etc, and have NO idea of mine, but assume my wt is "normal" since I'm not a fulltimer and dont have a huge bunch of STUFF in it....do these pressures sounds pretty close to what others run? It's been on a 450 mile trip with no problems and my pressure pro shows front pressures going to about 128-130 on the highway with temps in the 50s

Larry, No problem with the increase in pressure with driving and the natural increase in temperature. I run mine 115 in front and 80 in all rear, including tag. Mine have and are, running great. Newmar's suggestion indicated same pressures on both rear axles. Works for me.

Are any of you using Nitrogen in your tires? I used nitrogen in my Mountain Aire but didn't put enough miles to tell if it helped.

The information about the tire pressures is a help, so thanks

Hi Nut...
Your coach is probably alot heaver than mine...I assume we both have the 305s, so maybe Im overpressured...better than the other way and the ride is ok

No, mine are 315's. Weighing each corner is definately the way to go, however all axles are the same on each side. Check out Michelin's inflation table. It spec's pretty well for mine.

Oh, my weight is 46,000 gvw. My wet empty with all options is 43,500. I'm around 44,700 loaded. Not much c.c., however actual gvw by axle is 46,600.

I recently had each axle weighed at a CAT scale. I have not found a truck stop scale that can weigh each position. My front axle (full of fuel and 75% full water tank) weighed in just below 14,000. The 2006 MADP 4304's are close to max on the front axle. I don't remember the rear weights, but they were far below maximum ratings.

My front tires are usually at 110+ psi depending on outside air temp. Drive tires at 85 and tag at 75.

Hi Jerry....so since we have the same coach, my front will be fine at the max 115 and my rears match yours, but I never carry more than 1/4 tank water...so if you havent trashed some tires yet, I think I'm safe too!! I only have 5800 on the clock

I had a 2006 MADP 4304 (getting an 07). I had conversations wiht SPartan and Michelin. Basically keep the 6 rear tires at the same pressure (for me 80 psi) On the front I used 107.

My left front was about 700 pounds heavier than the right front.
