1982 Winnebago Brave tire pressures

Hi Folks
I am new to this , so please bare with me. I have owned a 1982 Winnebago Brave28" for the last 10 years. Last year I broke down and bought a new set of tires for it. The tire are 285/85 r16, it says on the tire to run them @ 80PSI. The original tires were bias ply and I don't know what the pressures were suppose to be (tire pressure sticker is missing) The place that sold me the tires said to run these tires at around 55psi as they were on bias rims. ?????? Gas prices being what they are and as well as handleing aspects leads me to think 80 would be appropriate, but I am scared of blowing the rim apart. Any ideas?????? Kevin

Sure. Start from scratch (with good new tires).
And assume that Winnie didn't know in 1982 what a good radial tire would be able to do in 2010.

1) Accurate weight at each corner and axle of the coach.
eg: 14,000lb Coach = 9,000 rear (/4) + 5 ,000lb front (/2)

2) Read the MAXIMUM weight at Xpsi on the tire wall.
eg: 3600lbs dual @95psi (and) 3400lbs single @95psi

3) Do the math.
Rear: 9,000 / 14,400 (3600x4) =62.5% (x95psi) = 59psi
Frnt: 5,000 / 6,800 (3400x2) =73.5% (x95psi) = 69psi

This you get the MINIMUM air pressure required for good condition NEW tires to support the KNOWN load.

Cheaper, older and/or worn tires become a crapshoot.

Hope that helps.

Check the backside of your wheels, They may be maxed out at 65 PSI and they are marked with the MAX PSI.

NOTES on using radials on bias rims (from Wiki).
There is no such thing as a bias rim. There are bias ply/belted tires and radial belted tires. Tires have a rim size as part of the tire size molded into the sidewall. Metric radial size would be something like 195/60R15. The R designates radial and the 15 isa the rim size in inches. A bias tire would have size listed as something like an FR78-15. The 15 again is the rim size in inches. Any tire designed for a 15 inch rim will fit as long as it's not too wide or narrow. They may still fit but not quite properly.

The rims do not sound stock to me. I thought just about all RV's in 1982 had 16.5 rims not 16".
Lower air pressure gives for a softer ride, more sway and hotter tires (can cause blowouts).

I run my 86 F250 Class "B" MH at 50 PSI front and 70 PSI in the rear with "D" rated 16" tires, any less than that and it is all over the place going down the road.

I also run my 94 F53 Class "A" MH at 80 PSI front and rear with "E" rated 16" tires.

The 1982 E350 Class "C" MH I run it at 50 PSI with "E" rated 16.5" in the front and "D" rated 16.5" at 50 PSI in the rear.

rv tire pressures

Thanks everyone for everything. Rims are stock 16" and the inside of the rims were stamped 65 lbs. I am running 65lbs and the ride seems much more stable and I seem to think it gets better milage too. I will check that as time continues. Thanks again everyone for your advice. Now I got another problem....... Please see 6.2 acting up in the title. Thanks Kevin
