245 VS 265 Tire Sizes

[TTaves]

I have an '06 3500 srw with a Big Foot 9. 4 camper on it (love the camper by the way but it is not light). Posted GVRW on the truck shows 9900 lbs. I went to a certified weigh scale yesterday and the gross wt came in at 11260 lbs. I am under on the steering axle but over on the rear axle. I feel I can get as high as 12000 lbs, when one adds the wt of the grey and black water, groceries, another passenger or two etc. In any event I have already added the Firestone air springs with compressor which at 90 psi does a good job of levelling out the rig.



My question realtes to the Rickson 19. 5 Eliminator Wheel and tire recommendations for that. Currently I have the BFGOODRICH T/A 265/70R17's. I was thinking of Michelin tires(xds2 lrh) and either 245's or 265's. Do any of you fine folks have suggestions and or experience regarding the advantage of either size and the Michelin's.



Thanks in advance for your remarks and any other suggestions you might have for my weight situation.

Have you thought about going to a higher rated 17" tire? Toyo's 285/70/17 is 10 ply rated and weight rated for 3750lbs.

How much weight are the oem wheels rated for?

 

[TTaves]

Not sure how to tell the weight the tire can sustain, just that I know they are E class for weight bearing. I did not know that one could get larger tires for the oem rims. Still wondering though if 3750 would be enough. Was thinking about F or G weight rating.



If I decide to still go 19. 5 on the wheel set, any indeas as to if a wider tire (265) is better/worse than the more narrow one (245)?

my oem tires are rated for 3195 pounds.

The wider tire would certainly look better.
