03 ram qc hemi with 33" bf goodrich a/t's. can anyone give me a guess for mpg?

 

Should be the same as all rams with the 20" wheel option. Those tires are 32 1/2" So your looking 15-17 hwy and 12-14 town

 

how much do you think it would change with the 35s?

 

Probably a mile or two per gallon.

Do you tow? If you tow a lot, keep the 33's or regear with the 35's.

 

Your really not going to notice much of a difference that is going to really make a differencewith 33's. What gears are in your truck?

Once you start going to 35's or bigger you'll notice a big difference. But, when you start getting into the bigger tires, you'll want to regear which will give you some of your mpg and power back.

 

i do about half and half on city and highway, not counting offroading i'm around 13, but alsotake in effect i hace cold air intake and ful catback, it helped some

 

i have an 04 qc with 35 BFG A/T's and i get about 11-12 mpg with a full cat back exhaust as well....but they look pretty damn good on there....they were on there when i bought it...once they are bald i will be lifting truck higher and putting 38-40s on i'm sure...
