Did anyone notice their fuel mileage drop significantly after putting on BFG A/T's? I used to get like 16 mpg city, 22 highway with my stock Goodyears, but now I'm getting like 12 city, 17 highway.

 

did you go to a bigger tire size?
if so its because your speedo is off.

 

I went from a 255/70/16 to a 265/70/16. My speedometer is 100% accurate. I'm pretty sure it has to do with the tire weighing like double what the stock tires weighed.

 

BFGs and steel wheels.

 

lol goodyears have nothing to them, thats why they suck. Now you have a good tire it actually has some meat to it. Its going to weigh more which is going to give you a decrease in fuel economy.

 

steel wheels do not help at all. honistly get alum and that will solve a majority of the problem..

 

I already sold the steel wheels and went back to the factory wheels because of how much they weighed and the fact that they couldn't be balanced.

I figure 3 mpg at 10k a year isn't that much...maybe $250 a year or so in gas. Some of my fuel mileage loss has to be from the switch to the winter fuel.

Part of me says sell the BFG's while they're still new (they have 400 miles or so on them) and they're like new still...and part of me says just keep them. The Uniroyal Laredo Cross Country is a decent-looking tire and it's a lot lighter than the BFG AT...If someone offered me $450 for all 4 new bfg's, I'm pretty sure I'd take it. Although it is a really good tire compared to the stock goodyears...those things couldn't keep traction in the rain let alone the snow.

 

most of it is winter fuel like you said i dropped from 19mpg to 16mpg after they switched.. another thing invest in a tuner you will be surprised..

 

Yea my fuel mileage sucks now as well with the winter fuel, keep the BFGs man.

 

Watch the lead foot too.....LOL

 

i still get over 22 mpg with my bfg's

 

yea i dont have an issue with winter fuel either.. maybe 1 mpg...

alot of guys leave their trucks warm up... i just turn the key and put it in drive..

 

best highway mileage I got was with my 31x10.50x15 BFG ATs, the stock tires with the Level II package. I hit 21.6 on one of my long distance trips. Most of the time my trips ranged from 18.9-20.1 on highway trips with the ATs. My MTs are another story since they are 33s. Plus I'm sure the 4.10s help for me too.

 

Going from a stock tire/wheel combo to 33 inch BFG AT's I only notice right around 1 mpg city drop and nothing on the highway.

 

i havent let it warm up once this year its been to warm

 

i was just saying its not really winter fuel, probably has more to do with warm ups and cold air.
