?? about tires size for fuel mileage!!

I dont think you will see that big of a difference, yes you will add rolling resistance, so you mpg might drop, but like i said i dont think it will be to drastic to notice, 1-2 tenths perhaps.

 

eskimo posted some hard number on this from his operation awhile back but I forget where he posted it. You have more rolling resistance and more weight. I believe he said the found a 1/2mpg difference between the tall and low rubber. the biggest avings was to go to low pro 22.5's but not everyone wants the cost involved with that and you are not geared for it. Personally I'd stay with the lp 24.5's. my truck has tall rubber and i'm contemplating going to the l.p.

 

I think eskimo posted going from 11R24.5's to lo pro 22.5s, then yes there is a big difference, but between 24.5s i dont think he will see much of a difference. 1-2 tenths.

 

he posted both. just can't remember where it was

 

I'm thinking about going to the wide-base singles.

 

From the research I have done they are not showing much if any benefits when factoring in initial cost, difficulty in finding in route replacements, wear milage and MPG gains. my 1/2 cents worth

 

From just my seat-of-the-pants figuring I can see that replacing existing duals wouldn't be a good idea (at least not for reefer/van), but I want to look closely at whether they make sense when spec'ing a new truck.

 

it's a wash. they do get better mileage but they wear out faster so money wise it's a wash. some people like them some don't. it is a bit worrying about trying to find them out in the middle of nowhere though
