Hey JR, don't be so hard on Ed. The last time I looked the D range tire was
stamped with a maximum weight well above that needed for our vehicle. It's
a much better tire than the cotton sidewall ones I grew up with. Also, if
blowouts were as catastrophic as they are being painted, I would be dead.
I've had a wheel well destroyed and a wall moved 6 inches on a blowout in
this thing but it didn't drive all that badly when it happened.
That being said, I don't care much for repairing damage or changing tires in
traffic so I want the best I can get which currently is E range. I'll even
change out my G159s next year when they go over 5 years old.
Some of us amateurs like to hear all views so keep up the controversy.

Ed,

I have to agree with Tom Warner. I don't know why you bring up the "D" tire
issue time and again. You have had good luck with your cheap D tires, but
that luck may run out someday. I hope it doesn't for you and others that
continue to run the D's; but if it does, may the life you take be your own
and not that of your family or innocent bystanders.

You other netters, especially new ones, read the article by Wes Caughlan of
Cinnabar in their June 1999 issue of the GMC Motorhome News. Wes is
responding to the "D" tire issue raised by our own Tom Warner. Wes goes on
to say that his firm proved to GM that the General Tire "D" tire was prone
to
failure on the GMC coach and GM allowed General Tire to recall all the "D"
tires to be replaced with "E" tires. GM also recommended the "E" all steel
tire as the only one that could withstand the unusual lateral forces the GMC
Motorhome exerts on its tires. Wes sez that the reason for Load Range E
tires is the inflation pressure and this pressure determines the load
carrying capability of a tire. The article explains much more than I am
writing here.

In his final paragraph, Wes sez "One of the problems with Internet
Newsgroups
is you can't tell the experts from the amateurs. Also, know-it-all amateurs
seem to be more vocal, and are all-too-frequent contributors".

Ed, it sounds like this paragraph was written for you. It would be best
for
all of us if we just followed what GM recommends; and that is the "E" tire.

Enough said.

there are two sides to all situations - everyone is concerned about the
stress on D tires in normal driving then I see all these bragging
commentaries on how 'I passed everything on the road - was cruising at
80 mph'

there is no truck tire made that is 'rated' at 80 mph at maximum load -
I would feel much safer on a D rated tire that is within weight limits
being driven at 55 mph in a conservative manner then I would any E rated
tire at 80 mph bouncing off of ruts and curbs

I currently have D tires on my GMC - the rears are 8.75s - the fronts
are 9.50s - I drive conservatively - very seldom above 60 mph - I will
replace them with E tires as they wear out and I can afford them

I think the margin of safety on an E tire at 60 mph is worth it - I
don't think there is any margin of safety on any tire at 80 mph
