Whats uppppp!?!

I know that going wider tires (eg. 195/60/14 or even 205/60/14) vs. stock 175/65/14s would affect my cars fuel effeciency. But I just want to hear from people if they ever noticed a bit of a loss in mpg by upgrading to bigger tires (or wheels/tires in that matter). thanks for the input

Nope. I got 27-28 mpg no matter what size tire and wheel (14x5.5, 15x7, 16x7.5)...well, except for the 15 mpg I got during DEs.

As long as you don't get too crazy by putting on some 20's or something, fuel efficiency will not suffer. And doing a few minor bolt-ons will actually increase the efficiency of your motor, improving your gas mileage as long as you can keep your foot out of it.

205/60 r14's are very big, slows down the speedo and a whole lot of sidewall, a whole lot.......

I lost 1-2 mpg on my truck by going from 215 65 15 to 235 60 15.
I do pizza delivery and keep detailed records on this stuff since it affects my income,but I don't think it would hurt the average consumer.

It doesn't really make any difference in your milage.
I have upgraded to 205/50/15, it has pretty much been the same, as long I don't go crazy with the gas pedal.
