Hey hows it goin yall.. i have a question for those who are running 38"s, i'm currenty running 35"s and i get 17 mpg mix city/hwy what would i get running 38"s and 4.88 gears? i drive like a grandpa. the reason im asking is cuz im stuck between either getting new 35x14.50's or buyin gears and upgrading to 38"s. but i wont upgrade unless i can get 15. thanks for your time and heres some pics of my truck.

 

don't know about your question. but nice truck and welcome.

 

welcome and sweet truck

i think if you go with 4.88's an 38's mileage shouldn't change that dramatically, considering you said you drive like a grandpa.

 

you should be good with 4.88's and 38's i dont think 15MPG is out of reach.

id say 12-15 MPG.

 

Sweet Screw!! I'd go with 4.88's and 38's.

 

Dude, your truck is BEGGING for 38's, with the gears and your driving habits, 15 is not unreachable.

 

You're not going to get 15mpg driving like a grandpa with 38's, my truck with stock gearing and 285's could barely get that on a good day. With that said, if you're even thinking about going bigger, do it, because you won't regret it. You're probably gonna be looking at about 12-13 mpg average with those gears and tires
