So, don't ever repaint or get reupholster(get rid of those awful gawdy
fabrics)? Come on Ed, I know the state of the art has changed in 26
years. It's an individual thing - some people wish to keep 'em
original, others want to try for something better. There's room for
both on GMCnet.

Heinz:

What gauge do you recommend that one use to measure the GMC ride quality
.

FWIW, based on the recommendation of Chuck Stoddard I've run E rated
Bridgestone R 265 series tires @ 55 lbs pressure, for two years (guessing
probably close to 15 K miles, gee I better look at my log when I get home
tonight) now, and like our ride. To me it rides like a Towncar.

Ed,

what pressure are you running on your D's ?

I've been running D's forever (230k+) at 60-65lbs.

I do have E's on the front at the moment. The rears have too much tread left
at the moment so I have some time yet to decide.

I am wondering about how much harsher the ride will be. What pressure is
used by the folks? I noticed 80lbs in another post. Is that correct?

We were recommended to us D rated tires by a GMC owner who is also a Tire
Dealer.

There is an advertiser in GMCMM who also purchased tires from him and he
insisted on E Rated all Weather Tires. On the way to Florida, he blew out
two of them.

D rated tires have a softer ride than E rated tires. As long as you comply
with the tire weight rating and air pressure I'll stick with my cheap Ridge
Runners and the D rated tires -- I'll take advise from someone with
experience anytime.

If my monitor doesn't fall off the table because I forgot to tie it down the
ride is of high quality :-)

Same goes for all the other gauges, partially filled coffee cup on the
counter, fridge door unlatched, etc.

Sometimes I really don;'t know how I managed to fly an airplane [g].

The above is what's worst about travelling solo. Makes for a few unscheduled
stops shortly after official departure :-)

...and no chastising about checklist... let's be nice [g].

That's good to hear. I was planning to continue on with 60lbs regardless of
which.

One thing I better correct after rereading my below comments. Chuck
recommended the tires. I decided on the tire pressure after consulting with
the tire supplier, who looked at his charts.

One thing I don't remember seeing mentioned is that with any tire, D or E. when
the pressure is 60 - 70 psi, when the tire gets warm from driving your pressure
will climb to 90 or even over 100 psi. This is not a bad thing, but make sure
the tire shop uses steel valve stems. This is more important than almost
anything else. The rubber stems are not rated for this kind of pressure. You can
loose alot of pressure real real fast when your valve stem blows out. Darren

Don Wirth who was with Goodyear told me when I put on the alcoas and the new
G159 that tire pressure should be 60 in front and 55 in rear. Since he worked
for Goodyear for 37 years, and was an expert on tires, I would believe him.
Have been doing that for some time and it seems to be running fine with no
problems.

I don't believe any 6 tires made will carry 12,000 lbs at 50 and 55 psi.
they have to carry 2,000 lbs each and without checking the tables I think
one would be marginal at that point. If you weigh your coaches by each
wheel you mayl find you exceed the axel rating AND the tire rating for
that wheel.

It is interesting to see signs of over inflation at that low psi, though!
