Tom;
You asked for more info on the tires I bought. Here's what's marked on
the sidewalls; DUNLOP A/T RADIAL ROVER 8.75 R 16.5 LT 115 / 110 R
Also, they're marked as being 10 ply rated but are not actually 10 ply. The
tread is 2 ply polyester + 2 ply steel + 2 ply nylon, and the sidewalls are
2 ply polyester. I guess we're putting a lot of faith in Dunlop's "10 ply
rated", huh?
They're rated for a maximum load of 2680 (single) or 2360 (dual) at 80 psi
cold. Since my coach weighs 4440# in front and 7280# in the rear, loaded
for travel, I feel pretty comfortable with their capacity.
I didn't think the price was too bad, ($123, balanced) but I'll definitely
do more checking before I buy the next 4. The collective wisdom on this
site will surely provide ample information on the choices available to us
"cavemen" who are still running the steel wheels.
Regarding size, I'll be replacing 9.50 F's on the rears with 8.75 E's
because when the suspension is all the way down the 9.50's are WAY to close
to the air bags, skirts, floor, etc. If I have an air suspension failure
I'd at least like to be able to move it to a safe spot without doing more
damage. I really don't understand the reasoning behind the use of 9.50's
insead of the originally designed 8.75's anyway. If the 9.50's were better,
why didn't GM use them to begin with?
Enough rambling........
