Can anyone from experience tell me which is more desireable between the two rim sizes? also, between the two tire sizes...225's or 245's. Which combo works best.

The truck will be driven unloaded or not pulling anything 2/3 of the time being used.


Thanks

 

A friend fo mine has 225's BFG Mudd terrian on his Dodge Dually.

 

that size on 19.5's or on OEM 16'S?

 

I am going to take a guess that you are talking about 19.5's. If so, I would go with the 225's becuase that are usually a little cheaper with tires then the 245's. That will also help if you are on the road, I would bet more places would stock the 225's over the 245's. JMO

 

thanks for responding. I was looking for more of a performance stance. I understand that the 245's would probably cost more(thats a given). I was looking for road characteristics and of such.

thanks again

 

If the truck is mostly unloaded, then the Ricksons may not be the best option for you.

But if you've decided you need them, then I'd go with a narrower wheel and smaller (225 or 245) tire.

The 6" wheel mates better with the 225 tire, but the 6.75 works fine as well.

Why 225?
-- Costs less
-- Available in lighter load ratings (F) so it rides better. (ever ridden on a LR H tire in a 265 size! OUCH! Might as well be steel train tires!)
-- Better mpg from lower rolling resistance of narrower tire
-- Narrower tire resists hydroplaning better
-- narrower tire is better for snow traction
-- The 225 size is pretty close to factory 265/75r16 tires in terms of gearing (revs/mile), so towing power is unaffected. Going up the the 245 and 265 Ricksons will make for tall gearing, and reduce towing power.

EDIT: never mind-- I read your sig.

I've got the 245/19.5 (Dunlops) on 6.0" wheels. Widest you can put on 6.0' wheels.
Load Range H for hauling the truck camper. 4940 lbs load rating each.
The 245 19.5's are only 1/2 in. taller than factory 265/16's- speedo is 4 mph slow.
The 19.5 treads are quite a bit narrower than the 'baloon' factory 16 inchers- don't try any beach running with the 19.5's! But they do dig thru snow to hit pavement pretty good.
The 19.5's don't ride too bad empty if you air them down to 50 psi- but don't go any lower as they will break the bead seal.
These tires wear like iron! 40K miles on mine and only 3/32" wear. (out of 11/32)
