'87 Bounder tire pressures & other stuff

Hi all ,

Our 1987 fleetwood Bounder has tires that are around 2-2 1/2 years old tires on (were purchased new by the previous owners not long before my Wife bought the coach) they are the orignal size/profile of 8R19.5.

Now the outer tire wall on one is cracking ,the main question is of actual tire pressures.. Its a 34 foot bounder and i know exact pressures are for the original vehicle weight plus extras, Im just after a rough idea for standard pressures front & rear (taking purely the basic coach into consideration)
It has dual rear wheels.. and a rocket industries front axle.

Would i be right in thinking of around 90-100psi in the rears? Asking this as nothing in the paperwork for the coach or any label on it mention the pressures. Or i cant see them for looking!!!

Can you still get the 8R19.5 tires? Been reading alot on here & other message groups etc about the difficulty in obtaining these.. and the fact of the more modern 225/70R19.5 tire being a more appropriate size for handling & stability and availability.

Also out of curiosity about the front axle (rocket industries) does anyone know of a source for spare/service parts for this? Brake rotors/pads etc?

Thanks in advance for any help

Paul and Ro

Paul,
I believe that size tires were rated maximum pressure at 85 pounds, but not sure. On our '97 32 foot Bounder the label said 85 pounds. The new Michelin XRV tires have different ratings [100# maximum?] and I have tried different pressures according to the Michelin web site [after weighing the motorhome] but have settled on 85 pounds all around. The listed GVW on our rig is 16,500 pounds, and I would be surprised if your's was more than that. What brand is your tires? Do they have a web site? Both Michelin and Goodyear have a lot of information on their web sites, worth reading.
Never heard of Rocket Industries, what chassis do you have?

Loren,

i think the GVW is around that weight of your coach maybe a little less..
As for the front axle my mistake , its actually a Rockwell Industries axle.

Will have to look again at the tires , and check the companies site for info.

Its on a John Deere chassis with a ford 460 engine with a C6.

Paul,
There has been some talk of changing tire sizes on the Bounder e-group, but I can not remember what sizes they switched the 8r tires to. We have several people on there with the '87 to 89 "classic" Bounders that can answer more specific questions better than I can.

You can also try the Fleetwood forum on this site.

Question Tire pressure ????

Paul, in one of the cupboard doors should be a sticker and the tire pressure is printed on the bottom of the sticker.
It took me two years to SEE the sticker in my new coach.... the other door had the weight sticker. It just did not click, that the tire pressure was written down... Learned it on a (short) tire lesson last week.

I thought that may be the case TW!

After a thorough inspection of all the stickers in the cupboards nothing to
be found regarding tire pressures!

A long sticker with all the weights & such.. nada about pressures..

Hmmm will have another look through what paperwork came with the coach.

Usually there is a sticker to the left of the driver seat, below the window, with weights and tire pressure on it.
