OK, here's the secret list

"Verified Low Rolling Resistance Tires

Based upon data provided by tire manufacturers and EPA testing and research, EPA determined that certain tire models can provide a reduction in NOx emissions and an estimated fuel savings of 3% or greater, relative to the "best selling" new tires for line haul trucks, when used on all five axles on long haul class 8 trucks.* The options offered include both dual tires and single wide tires (single wide tires replace the double tire on each end of a drive or trailer axle, in effect turning an "18" wheeler into a "10" wheeler).* Low rolling resistance tires can be used with lower-weight aluminum wheels to further improve fuel savings.

To date, EPA has verified the following low rolling resistance tires. *In order to be eligible for funding under the DERA, verified low rolling resistance tires must be specifically listed on EPA’s verified technology list.

The following low rolling resistance tires are SmartWay verified when used on class 8, line-haul trucks:

Anyone had experience with these and did you notice any fuel savings?

 

tracer that list is somewhat misleading, because there are tires out there that have lower rolling resistance yet aren't on that list. Michelins site has a rolling resistance calculator.

 

i tried their calculator but couldn't figure out the abbreviations for the truck and trailer configuration... is there a simpler version of this somewhere, the "for dummies" type?

tandem axle truck - 6x4 or 4x2?
tandem dropdeck trailer - ?

 

6x4 and just any tandem trailer, doesn't matter that it's a step deck

 

they were steelmark. paid 2 grand for the whole 9 yards. no trade in. none developed any dips, got 6.8 m.p.g. on a mil mile truck. I did have to have a few flats fixed thruought their lifespan. they are not as deep in rubber, so some things will puncture all the way thru if you run over nails, e.t.c. on the deep lugs, many times , I would pull a nail or small bolt out & still be o.k.

the steelmark is a inexpensive chinese tire. I may try a better brand, just to see if the ride is smoother. long ago I had kelly steers & thought the ride was normal. felt like they bounced my eyeballs outta me head. went to b.f. steers & it was such a huge difference, I would not of beleived it unless I experienced it my self. the b.f.'s rode like a dream compared to the kelly's.

 

I have 10 BFG ST244s on my tractor and love them. Great ride, mileage and quiet too. Wearing perfectly.

Lugs don't make as much difference on a class 8 truck as they do on a four wheeler. Truck suspensions are too stiff for the tires to have as much effect as you might want to think, especially when you have all the weight/momentum added to the situation.

 

I think the bfg st244 is what I have on my steers. I thought about going with them on my drives, or a regular hyw tire. someone told me that a kelly kda weighs 20- 30 lbs more than a hwy tread & has a lot more rolling resisstance. the main thing I liked about the hwy tires I had was the ride. if a lug starts to dip, you either put up with it or change it. just like anything else... personal preference.

 

to the people that are running steers all the way around.. are you noticing the truck is floating more? i'm wondering because i run a single axle if it has anything to do with it.

 

What part of US/Canada do you ride in? Does the truck handle okay in winter with these tires? What size tire is your BFGoodrich? I checked the specs and they do spin faster per mile than my current Yokohama TY517 (512 revs/mile). Thanks!

 

I have 22.5 at the time I had the steelmarks I was in MI thru a bad winter storm & had no problem. I know my kellys cannot spin as much per mile as the hwy tires cause they are min 2" taller that is being the same size, 22.5 standard. side by side the kelly are quite a bit taller. with the kellys, they are so deep that for the first 30,000 miles it feels like your driving on wet noodles.
