Load Range G wheels and tires?

That's really odd. No magic to changing inside duals on an E series, any reasonably strong and fit person with a standard lug wrench and a decent 6 ton bottle jack can do it. It's nothing like changing duals on a diesel pusher or other big rig. I do agree with you 100% on carrying a fully mounted and inflated spare at least on an E series sized rig.

I was told by an AAA dispatcher that their policy was not to change inside duals on vehicles. We had been with AAA over 30 years and for several years have been on their highest (premium) plan. We now have Coach-Net's premium ERS plan - less cost than AAA and far superior benefits (per what's written ... we'll see in real life situations).

Remember that changing a tire on a motorhome's rear dual set can entail lifting and supporting MUCH MORE weight than what's on one rear corner of a 1-ton dually pickup or a passenger vehicle. For example, I'd hate to have to mess with a motorhome's passenger rear corner with some of the soft shoulders on the two-lane highways we travel on!

BTW, you might want to verify that your current ERS will change failed inside tires of dual sets on motorhomes. We recently found out that our ERS (we're been with them well over 30 years) has a policy TO NOT CHANGE failed inside tires of dual sets. We reluctantly dropped them and signed up with another ERS that had no policies against full service on motorhome tires in any position

Wraped it inside 2 trash bags, 50 gal. Then put it back under mh.

You have a large and heavy Class C. Who's going to change your flat tires on a trip - probably your Emergency Road Service (ERS)?

If you were to have a flat on an inside rear dual along a busy highway or along a remote highway with fairly steep and/or soft shoulders - not the best of situations to have a tire failure in - the ERS will have to both get at and remove the inside rear dual failed tire, plus take off a front to put there, plus put the spare on the front. I don't see all this happening in many emergency situations.

Remember that with a failed tire in any position in the rear, you CANNOT merely continue driving for miles counting on the remaining good tire of the dual set to carry the entire weight of that side in the rear until you get to a good spot for the ERS to make the mulitple tire changes required. This situation places a tremenduous over-load on the remaining good tire of the dual set and it is then very dangerous to move much at all this way ... especially with a large heavy Class C.

It's best to always carry a full-sized spare and wheel of the same load rating and size as the running tires on your RV. Also, keep this spare inflated at all times to the HIGHEST inflation pressure (usually the rears) that you are using on any of the running tire positions.

Do you do anything to keep the tire from getting filled with road grime?

When I ordered I included a 7th tire, not mounted. I have it as a spare just in case. Any good road service can mount it for you. this way you won't have anny mismatched tires, which could be a problem, or could not. For the extra $$ call Dan and order another tire.

Hmmmm ... will that spare Load Range D tire/wheel combination have the same overall diameter as the others you're running?

They definitely won't be the same diameter. I figure if I lose a rear tire I'll just switch a front to the rear and put the slightly different size spare on the front. I think it is fine to have a slightly different sized front tire on one side, do you agree?

I've always tried to carry a spare with the same diameter as the running tires for all vehicles I've ever owned.

I ordered a set of wheels and tires today. After spending some time talking through the options with Rickson, I settled on the load range F tires and full wheel simulators. The F's will give the rear axel 14,000 LBS of load capacity on the tires and will hopefully stop the inside passenger rear from being overloaded. The F's will take almost 1,000 LBS more load per tire that the D's, though I do realize that the rear axel itself is only good for about 9500lbs and that tires will not increase that at all.

I should have them in a couple weeks, so I'll post an update after my next trip.

Oh, I am planning on keeping one of the existing load range D wheels and tires as a spare. I figure I would put one of the fronts on the rear and the different sized spare on the front. The front is a much lighter load and I think the D's handle it just fine.

I have put on my C Class 235-85-16 load range G on my stock rims in rear with out any problems I keep front wheel stock size. The rear hight was raise rear about 2 inches and ride is a little firmer but not that bad and handles great got about 40,000 mile on them look like new. Almost 5 years now .
