My 96 1.0 3 banger Geo has had several 57 mpg best mpg fills in the last two years. The original 155/80/13s rated at only 35 psi max were swapped out for 195/50/15s that had a 51 psi max. The new tire/rim package was 8 lbs heavier than the old stuff so I removed an extra 32 lbs from the interior so the total wt of the car was still 1630 lbs. I was still getting fuel fills at a best of 57 since the new stuff had lower rolling resistance. Where I used to be able to coast to the next red light now can be done from a longer distance away. I added a grill block and headlight covers but I started to have EGR issues and couldn't get a good mpg reading. I FINALLY ironed everything out but now winter weather and winter gas was here. Spring has sprung and I decided that a MODERNset of the lighter wt 155/80/13s would be the next ticket to better mpg. I got some 44 psi Kumho Powerstar tires in that size and mounted them on 11 lb Primax rims for a total rotating wt reduction of 10 lbs per corner from the 15s...40 lbs removed in just a few minutes. My last four tank fills have netted over 60 mpg with two being63.0!!! The attached link shows the car on the 15s with the aero mods in place.

I drove over 300 mile today and squeezed out a 61.7 mpg. Keep in mind that I carry at least 100 lbs of extra wt consisting of rims or tires that I sell AND deliver.
