My centramatics are pretty thin where they mount to the hub. Maybe 1/32" or less?

Centramatics are a great addition to your coach but will not give you more than 1/16". The plate that goes on the hub over your lugs is very thin. We have run them on all three of our CC's.

I know spacers are made because when I changed tires on trucks with 19 and another with 16.5 inch wheels that rubbed the tire sales manager just walked back to the warehouse onsite grabbed three sets of different thicknesses, chose one and I had no problems. The only issue is are the studs long enough and is there enough fender clearance .

Actually the Accuride wheel guard separator plates are only .04" thick (very thin). They are made of a composite material to protect against electrolysis when using a steel wheel and an aluminum wheel bolted together in a dual configuration (like on most Class A motor homes).
So that won't really work for me. I'm looking now for some other spacer plates. I'm sure they are available, although I'm sure the outer dual cap nuts would have to be longer.

The hunt continues....

The plot thickens...

I talked to a very knowledgeable tech support person at Accuride. They don't make any spacers to change the offset and don't recommend their use due to changing the load on the axle bearings. He said the correct "fix" would be to move to 9" width wheels which greater offset. The offset is in on the inn er tire and out on the outer tire and balances out without placing additional load on the axle and bearings.

When I told him my desire for 315/80/r22.5 tires on 8.25" width rims, he recalled a design guide page in the Tire and Rim accosciation spec that did approve 315/80's on 8.25" rims with 13.2" dual spacing.

The pdf document is here:
It derates the load for the 315/80's to 8000 lbs single and 7610 lbs dual (15220 lbs for the combined dual) when used on 8.25" width wheel and allows a 13.2" spacing.
This corresponds with the load derating that Michelin has in their pdf RV tire guide for 8.25" width wheels. http://www.google.com/url?sa=t&rct=j&q=michelin%20rv%20tire%20pdf&source=web&cd=1&ved=0CC4QFjAA&url=http%3A%2F%2Fwww.michelinrvtires.com%2Fassets%2Fpdf%2FRVTiresBrochure.pdf&ei=Bsp6Uca6N4P_igLCjoD4Dw&usg=AFQjCNGTNAmUZadaZ8wTxJLdimKAhQdLbA&bvm=bv.45645796,d.cGESee page 20 here: (this is a very good guide BTW)

It would appear from the load tables that I should be able to drop at least 10lbs pressure over the 295/80's. I don't know what all the wheels will weigh loaded, but I will get it weighed so I can set my pressures appropriately.

Does anyone with a similar 2006 Allure with tag have their weights per wheel/axle? I know it would be different than mine, but it would just give me an idea. I do like the fact that the 315's put more rubber on the road and give some breathing room with the load rating.

So I think I am golden! Thanks for all the help and comments!
