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: Bridgestone Steer* * R287A, R280, R250F, R260F, Drive*** M720, Greatec Trailer * R195, Greatec Trailer, Greatec R125, R197, S197 BF Goodrich Steer*** ST244 Drive*** DR 444 Trailer* TR144 Continental Steer*** HSL-2 (replaces HSL), HSR1 ECO plus, HSR2 ECO plus Drive*** HDL Eco Plus, HDL2 DL Eco Plus, HSR1 ECO plus, HSR2 ECO plus Trailer** HTL ECO PLUS, HTL1 Double Coin* Steer** Drive* Trailer**FT105 Dunlop Tire* Steer***SP384 FM Drive***SP456 FM Trailer**SP193 FM Firestone Steer***FS590 PLUS, FS507 Drive*** FD662 Trailer* FT455 PLUS Goodyear Steer*** G395 LHS Fuel Max, G399 Fuel Max, G662 Fuel Max Drive*** G305 LHD Fuel Max, G392 SSD, G305 Fuel Max AT Trailer** G316 LHT Fuel Max, G316 Fuel Max DuraSeal Michelin Steer** XZA3, XZA2, XZA1+, XZE, XZE2, XZA2 Energy, Drive*** XDA2+ Energy, XDA Energy, XDA3, X-One XDA, X-One XDN2, XOne XDA Energy, XDE2+, XDN2, XDE M/S Trailer** XTA Energy, XT1, X-One XTA, X-ONE XTE, XTE Toyo Tires* Steer*** M137, M154 Drive**** M657 Trailer** M127 Yokohama Steer*** RY617, 103ZR, 101ZL Drive**** 703ZL, TY517mc2 Trailer** RY587mc2, RY587 Hankook Steer*** AL07+, AL11 Drive*** Z35a, DL11 Trailer** TL01" 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.

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

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. |

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.
