Carl S should be able to help you out on this one. I believe he is running dodge 8" rims up front with a bigger tire, with a more aggressive tread
pattern. He runs a lot on dirt/sand roads.

I was doing the opposite, with a 255/70R16 LR-D on my 8" wide Dodge Truck wheels on the front (BFG All Terrains) and 225/75R16 LR-E on the rear. I
wasn't worried about the weight capacity on the front tires since they were bigger and were rated to carry a fair amount more weight than the smaller
rear tires anyway.

I think you might find a D rated tire hard to find. There are plenty of options in an E rated tire.

I have since switched to Cooper 245/70R16 AT-3 LR-E on the front. The BFGs wore out too fast.

Carl has the quadbag system. He could isolate out the rear tires so he could make it to a tire shop, within a reasonable distance, with a flat. My
spare would be the front tire..

Richard,
I completely understand your way of thinking on this. But on the other hand, it is nice to know that it can be done. But only as a last case
scenario.
I would still carry the front as a spare. If the rear had a flat I would disconnect the tow vehicle, pull off the rear tire and drive it to the
nearest tire shop for replacement. But only after I found a safe place to pull over. The quadrabags gives you that option of finding a safe spot.

Richard has been to and worked every weigh-in we have done at the GMCMI rallies. He has seen how much weight and out of balance the rears carry on a
lot of coaches. The idea of riding on a single tire more than a few hundred feet bothers me as much as it bothers him.

First of all to even get to the rated weight rating on the remaining tire you will need to stop, get out an air compressor, and air up the tire to 80
PSI. Even then you are around 1300 pounds over weight of the tire and wheel. The weight the tire is carrying is supported almost entirely by the air
contained inside it. So to carry that amount of weight very far I suspect some additional air pressure, well over 80 PSI, would be required. I went
to the Micheline inflation tables for an LT 225-75/R16 which end at 80 PSI. Extrapolating that info it looks like for every 5 psi added the tire can
carry an additional 250 to 300 pounds. So it appears that the air would have to be aired up to something a little over 100 PSI to carry all of the
the weight on one tire. That still does not help the wheel capacity.

They say Load range D tires can handle our weight just fine. but for me personally, from experience running a fleet of trucks/vans delivering over
the pacific NW backin late 90's, taught me that we had load range D on our trucks and tires were failing. We went with all load Range E, and the
flat tire problem went away. These were trucks that were inspected and weighed. It was not a constant problem, but one flat tire a month was a
hassle. I personally will only consider load range E tires for my coach. the extra cost is not worth worrying about.

my stimulus check just hit my bank account and so far my wife and I have been consitered essential and paychecks are still showing up weekly. So if
things settle down in the next month, I will be out shopping for another 4 load range E tires to mount on the 4 alcoas I picked up last fall to
replace my 7 year old 16" firestone transforces.

as far as spares. I have a pretty old good looking spare. It is a 16.5 ". I have run that on my front after chippawa falls rally, and I also
have the 8" wide dodge wheels. So as long as a spare holds air, I am good because it just needs to get me to the next tire store. I am not sure i
will put one of my 16" steel w/ the 7 year old transforces on as my spare. I am not sure it will clear my 80mm front calipers if needed. I may
check when I do the tire swapping. I will probably keep hauling around my 10 year old 16.5" rim/tire until I come across another alcoa rim for the
spare.

I just carry a rear wheel/tire, and an extra set of lug nuts for a spare. It will fit on the front just like the stock set-up. It may handle a
little differently, but I don't see it as a problem.

That said, I have never had a flat or a separation that I have had to change except on the rears, in almost 12 years and over 45,000 miles.

Most, even 26' coaches run about 65 psi all the way around. That is the max pressure for a load range D tire anyway, so theoretically a load range E
tire is not necessary. But, like I pointed out earlier, you will probably find it difficult to even find a 225/75 tire in LR-D.

Caerl, if the diameter is different by very much across the front, particularly if you have a limited slip differential, don't use it there. Stick a
good back tire up front and throw the outlaw on the back.

Cooper HT3s with very quiet tread and M/S rating in E load were last bought by me at about $120 per tire. When on sale. Can you beat that with Ds that
could he very hard to find and marginal on a heavy coach? Why?

Rich, I have a connection to a tire shop in Brampton. There don't do Michelin.
Would you like me to ask them abut 6 tires for you?

Johnny,

There is a scant quarter inch difference between the diameter of the 245/70 and the 225/75. I'm not worried about that small of a difference. I
don't think it will heat up the LSD very much. Of course, I have yet to try that theory out.

The Farm and Fleet runs buy 3 get one free. So for us just 25% off on 6 And a $70 pre paid visa card as well. Big Cooper volume dealer so fresh date
codes. Happens like 4 times a year. I brought in 3 wheels at a time so 2 trips (using spare and junk tire place holder). So I did jacking and
torquing.

tires and a jack :)

Rich, buy them here and then do a couple thousand miles seeing the sights so they aren't obviously new :)

Or bag a blank order form from the local store and fill in the numbers.
