moving from 225R75/16 to 235R85/16 PROBLEMS
Hi, More problems have reared their heads. The E-450 has a different rear axle, than the F-450. The F-450 will allow up to a 245 width with no change of rim size for the rear duals. The E-450...

Hi pnichols,
Everything I've read suggests that wider tires have less rolling resistance than narrower ones. The brands I'm considering are Michelin and Toyo.

Don,
I'd recommend looking at going to a Load Range E 215/85R16 set of tires - I did in the summer of 2011. This is actually a taller tire (about 1.2 inches larger diameter than the stock 225/75R15 size), so you wind up with about 0.6 inches of more ground clearance. The load versus pressure ratings are identical for the two Load Range E tires. The tread width is about 0.5 narrower with the 215/85R16 size, so you get better air cooling between the rear duals. If you get Michelins, you also get slightly better gas mileage from their 215/85R16 tires because they have less rolling friction.
Think about it, unless you really need the higher load capacity of the 235's!
