Anyone running these on a DII?

Bought mine about 6mos ago & have noticed a mileage drop, I was averageing about 305 miles b4 the idiot light would come on & now I'm lucky to get to 275.

No other changes( driving habits ect.) & there are no stored OBD codes. Any ideas? TP's 28/frnt 40/ rr

Thanks

Bob

I've been running 255/70/16's for over a year now, no problems at all.. getting rid of them shortly though to get a bigger size MT.

running this size in a mud terrain, if you plan to lift it, wait, i got these tires b4 my lift and regret having them

Well, you have gone from a stock tire diameter of 29.1" to 30.2". 60 MPH on the speedometer is closer to 62.5 MPH. The extra rolling resistance does require more energy to get moving but, you might be getting a bit better distance/MPG than it seems. At least that's what I've noticed using my GPS to track MPG.

Thats what I'd think also. Running 33's I figure my milage is close to 10% off

we've got them on a DII. your speedometer and odometer are now off by about 4% so your 275 is actually 286. Yes, there is a slight drop in economy and power by not too much - which is why i didn't go with a bigger size.
