Thanks Gary.
Hmmm ... it looks like what spacers are doing is putting more room between the two tires in a dual set by moving out the outer tire?
Is it intended that you leave them on all the time?
Don't you need way longer lug nuts then?
Doesn't it stress the bearings a bit to move the outer tire further out?
Doesn't it make the E450's wide rear stance even wider, then?
If the main goal is to merely put more air between the inward-facing sidewalls of each tire in a dual set to either ... permit no-rub airing-down or reduce rock wedging when off-pavement ... then I've accomplished the same thing without spacers: I now use 215/85R16 LRE tires on our Class C. This tire size is taller, but narrower ... hench more room between the two sidewalls in dual sets. In Load Range E, this tire size is rated for loads and pressures identical to those of the 225/75R16 size stock tires that come on so many Class C motorhomes. More room between tire sidewalls in dual sets also provides better cooling of the dual set tires due to increased air flow between the two tires - which especially helps when traveling in hot weather.
