My next expense is going to be tires, although mine have no checking, look like new etc they are 9 years old.
Looked at the Sears sale. Just for the tires, this includes mounting but not Taxes, disposals etc, and I rounded the numbers.
B.F. Goodrich "D" Com T/A 133.00
Kumho KL78 "D" 134.00
Firestone Destination LE 110.00
Big difference in Max Loads, the Firestone at 2094, Kumho 2149 and the Goodrich 2300+
Anyone here using the Firestones? Good/Bad?

Richard,
I've had Firestones for the last 7,000 miles and have no problems. Please
understand that it's a newbie's opinion, It's my first set.
My only concern is sears, based on the 20/20 report on selling old tires.
They seemed to reference sears as a repeat offender.

I put a set of BF Goodrich E series on Money Pit
less than 1/2 mile from when I picked it up. The
tires on the coach were a minimum of 8 years old.
They seem to be okay, but from other correspondence
here, I probably will drop the pressure on the rears
to around 55 before I take it on the road again. I
started with about 65 all around at first, but some
here have stated that it not only rides more smoothly
with less pressure at the rear, but handles better, too.

Still trying to figure all this out myself, but my understanding is that lower tire pressure gives you a hotter tire, which is what you want to avoid with older tires. When I first got my coach I had a LR at 47psi which measured 92deg, while the RR at 61psi measured 85deg. Granted there was a load/ride-height imbalance and the LR carried 150# more than the RR, so conclusions from this limited data are not clean, but FWIW.
But certainly it's not a linear function in any case, so you may gain margin of risk by lowering pressure a bit, but seems to me there will be a crossover where less pressure increases tire temperature enough to increase blowout risk.

Around here the Firestones are the only tire I can get in the 16.5" size
that are new rubber. I just replaced the 9 year old tires with new
Firestones. Mine are load range "E". Not that many miles. Maybe 18,000 or
20,000 miles. I had one blow out, so I changed the rest also. I now run 65
psi in front and 60 psi on the rear.

If you haven't weighed your coach, then I would say 55 is a little low for the rears on a 26 foot coach. I would come up 5 PSI to at least 60 with an unknown weight on the rears.

Huh? It looks like you are comparing apples and oranges. A load range D tire has the same weight rating no matter who makes it. The same goes for load range E.
I would also look at load range E tires. They are usually only 5 dollars a piece higher.
For tire size LT225/75R16 :
LRD tires carry 2335 lbs. at 65 PSI.
LRE tires carry 2680 lbs. at 80 PSI.
These are maximums. It you take an LRE tire and air it to 65 PSI (the LRD max), it will carry exactly the same weight as a LRD tire at that same pressure.
I would go back and check pricing on the exact same size and Load range tires.

Sorry Ken, please don't shoot the messenger, I typed what I read. All three tires were shown as 8 ply Load range D. When I looked at the specs, the maximum weights were different.
Me, I know absolutely zilch about tires.

I also forgot to mention what the Sears Rep told me when I asked about the age of the tires.
"We have no control over the age of the tires but they will not normally be over two years old when installed."
Just what he said.

He may not have control over how old they are, but you have control over whether you buy from him or someone else. Check the date codes yourself and refuse to let them install them if they are too old for you.
The six Kuhmo KL78s I bought were 2 months old when I got them. I would refuse to take anything over about 6 months old. I know you can get fresh tires from Costco, Sams Club, and Tire rack. The other major tire retailers ought to be able to give you fresh ones also.

I'm not trying to kill the messenger.
There is some thing wrong with the numbers you have and I did not want you to get the wrong tires.

I feel that unless your loading your coach with lot of weight, the rating is
not as critical as it would seem.
Make sure they are lad range E.
If yo are going to follow the 5-6 year rule for tire replacement, I would
lean toward the lesser price.
More important to keep the tire pressure up than worry about slight ratings
as it it mostly an marketing game when it comes to tire load ratings.
Lot of our customers in our shop fret over how we replace suspension parts.
Year later they have not bothered to take a grease gun to it.

You want something else to confuse you. I looked up my Kuhmos in LRD and LRE. They are one pound different in weight. It kind of makes you wonder what the real difference in construction is. One pound difference could easily just be a rounding error.

Just my opinion, but I wouldn't buy the Firestone Transforce tires.
Last fall I replaced 2.5 year old Transforce 225/75-16 LRE tires with Toyo Open Country HT LRE tires of the same size and the GMC drives noticeably better -- it's nowhere near as "nervous" on the highway. With the Firestones I had to be really careful doing things like tuning the radio or looking at the GPS because the coach would drift all over the road -- look down, change the radio station, look up, and you're drifting into the next lane. With the Toyos the coach continues going where it's supposed to without the constant steering corrections every half-second. Driving in crosswinds is no longer a white-knuckle experience. My local Action Gator tire store had the Toyos for $114.95 at the time so I sold the Transforces to my neighbor and bought 6 Toyos.
I've tried different tire pressures (60 rear and 65 front is best for me) and alignment settings over the past couple of years. The front end parts are new within the past few years, all I've left to do is find time to install the offset upper bushings to see what more caster will do. Bottom line is that, all else on the coach being the same, the Toyo tires drive noticeably better than the Firestone Transforces, and they are available at a reasonable cost. Made in USA too!
Again, just my opinion, YMMV.
