Re: Front Air Bags and Tire Pressure
Lenn, the frist thing you need to do is weigh the rv when loaded for a trip to determin the proper tire pressure. Sounds as though you may have to much air in the tires IMO. What is the cold recommended pressure on the tire sidewall for max weight?

Re: Front Air Bags and Tire Pressure
Ok thanks, here`s what i found out.
Tire say Trail Busters
Size--8R19.5 load range F
Tire says Max load dual- 5375 lb at 110 psi.
Door tag reads,
5,000 lb front axle---75 psi
9,840 rear---65 psi
All tires are at 110 now, sounds like I need to lower the pressure huh ?

Pitchy1,
I've posted this in the past, here is a description on weighing your RV with graphic worksheets. Should help you with your tire pressures.

This does not answer what pressure your air bags should be at.

Re: Front Air Bags and Tire Pressure
So this thread isn`t left unresolved i`ll post what my final results are. My door card says the front axel weighs 5,000 lbs so I take it that one tire has 2,500 lbs on it. If that`s the case then by the chart it says 75 lbs is correct which is also what the door card says. The tires are the same size that`s on the door tag also. I have no way to weigh the axles at this time so i`m going to put 95 lbs in them to be on the safe side until I can talk to a tire or rv dealer.
If anyone finds error in this reply please speak up.

Re: Front Air Bags and Tire Pressure
Doesn't mean there is 2500 on each. The only way to tell for sure is by weighing the rv when loaded. Air should be the same on front tires just aired to the heavest wheel weight. IMO Same with rear. The 5000 is the max weight if I'm reading your post right. 2500 or under equal weight on each wheel would be great but it can vary from side to side. JMO

Re: Front Air Bags and Tire Pressure
Think 95 would be plenty. I have never put more than 85 in mine cold and think I could go around 80 because I have weigh mine and 80 would cover. Ride would be better at 80 but think its better to have a little too much air as long as not over rated max than under inflated. IMO
