Sorry about the cap's


So it look's like I need to run the 110 psi in the rear .

I can run either 90 or 95 psi in the front , will the 5 lbs different make any difference in the way she drive's ?

as of now I was running 100 psi all the way around and when going down the highway at 62 mph I have to always move the wheel let's say 1 inch back and forth to stay straight . Do you think by adding 10 psi to the back dual's and taking out 5 or 10 psi from the front will help with this ?
Or is this normal Rv handling ?

thank you all for your help

i ALSO TOOK THE COACH TO THE TRUCK WEIGHT STATION ON THE SIDE OF I-95 JUST TO RECHECK , THEY CAN ONLY DO AXLE'S SO

FRONT 7580

BACK 16100

TOAD 3560

SO THE TOTAL WEIGHT OF THE REAR IS ONLY 400 LB'S DIFFERENT THEN THE 4 CORNER WEIGHT SO MAYBE IT'S CORRECT , NOW THE FRONT IS 670 LB'S LITER THEN THE 4 CORNER WEIGHT AND THAT'S WITH ME SITTING IN THE DRIVER'S SEAT AS WHEN I DID THE 4 CORNER I WAS OUT SIDE THE RV " 200 LBS MYSELF " NOW IT'S LOOKING LIKE 870 LB'S DIFFERENT IN THE FRONT .

SO BOTTOM LINE i THINK I STILL NEED 110 PSI IN THE REAR DUAL'S AND BETWEEN 90 AND 95 PSI IN THE FRONT

SO TOTAL RV WEIGHT IS AT 23,680 LOADED FROM TRUCK SCALE
AND GROSS WEIGHT WITH TOAD IS 27,240
THANK'S
MIKE

It does appear that the four corner weight adds up to the axle weights. I did a quick calculation of the fresh water tank and diesel fuel weights for the full tanks and get about 1300 lbs. To explain the right rear weight all of the weight of the full tanks would fall there. I agree that until you get information to the contrary you should inflate based on 9000 lbs on each side in the rear. You won't have a full freshwater tank often so that should be considered.

The old pump did 3 gpm and would have a pulsating effect while running, the new pump is 4.5 gpm and is a nice smooth stream( no pulsating ) and it is much quieter, could hear the old one the new one can't hear

My thought would be that any air you add will make it worse. These 22.5 tires are huge for the small amount of weight we have. I have never weighed mine but for sure know that it is light. I had 110 all the way around. I kept lowering and testing. The handling got better each time. I run 95 in the front and 90 in the rears. I can drive with one hand and no wandering at all. I put a stabilizing shock on the front axle at one time for 3000 mile. Hated it. It's laying on the shelf in the barn. I'm back stock and loving it.

Ya easy to change. I like what your saying about the bigger pump. Did you take the old pump apart to check it?

Mike I put 100psi in front 110psi rear and my ride quality is great. 33.3
I will monitor my tire wear.

There have been post here too where others have weighed theirs and have been advised by freightliner that they can go lower than 100
PSI. I noticed considerable less darting when I got under 100 pounds

[jimbooth25]

Yes I took the other pump apart just to see what's going on, there was a crack in the one pice of plastic and the water would just run out of that area when pump was turned on

I have a TPMS and I notice the tire psi goes up about 10 psi after running highway speed for about 20 minute's in South Florida at least .

so if I set front at 90 psi cold it will be around a 100 psi when warmed up same goes for the rear dual's if I run 110 psi it will become 120 psi when warmed up

Thor is going to reimbers me $150.00 for the pump, they wouldn't give me the whole price for the new one since it is different than what they would have put in the unit, witch I am ok with, they could have said no dice my one year was up on the 20th

That's fair deal. I was thinking new one like we have was only $50 or so. I must of been off on that.

Cold temp is all that matters. Temps probably go extremely high in the west.

When the high temp will matter is when one tire would go higher than all the others on your TPMS

I see that CW has that one on sale for $190, I hope you got the good price
