gas mileage question
i just picked up a g5 as a daily driver (the stang is now officially a weekend warrior) but it has 15" steelies installed (195/60/15) and the gap between the tops of the tires and the bottom of the wheel-well is disgusting.
i was just screwing around on tirerack and came across a set of 205/50/17 or 215/40/18 all season tires and am trying to do the calculations to find out how much mpg i will loose/gain with the new tires/wheels installed.
can anybody help me to find how much mpg i will lose? thanks
this is the website i was trying to use to do the calculations.
http://www.dakota-truck.net/TIRECALC/tirecalc.html
and if it makes a difference, the rear-end ratio is 3.84 and it is a 5-speed manual
