Hello:
Does any body know if, a change in a rims & tire size can change the gas milliage?
Exmaple mine use 235/70/15 I want to change to 235/75/15.
Or more big what if I change to 20'' rims?
Any change in gas consuption?

Also my truck is a 2001, B3000 this 235/75/15 fit in mine?
Will look ok?

thanks

 

go with eather a 30x9.5x15 or a 31x10.5x15...depending if you 4x4 or 2wd. you will notice like a 1mpg difference

 

we need more info and what your planning on doing it would help alot.

 

Well mine is 2wd I'm planning to use for a while original rims 15'' but I want
to buy the 235/75/r15.
Later I will buy new alum. rims 15''
I really dont want to make to much changes cause I use the truck to work, I'm sales man!

 

then get the 30x9.5x15 not the stupid tiny *** 235's...

 

I just send you an e-mail I like your truck can you tell me what I have to do to get a look like yours? How much do you spend$?
Do you upgrade your suspention?
send me an e-mail and I wil send you a picture of my truck to let you know.
Thanks bro
