Ok guys I've read some posts that stock rims actually help your gas mileage compared to the larger rims. I'm somewhat thinking the opposite and I'm just wondering, have I gone crazy or does it make sense.
Basically when I drive, I never past 3k. I shift at 3k or below. Maybe once or twice I'll take it up to redline for 1 gear.
My thing is the gas mileage in the 2002 gts. I'm only getting around 325 miles using about 12 out of the 14.5 gallons. This doesn't seem right to me unless I'm just crazy. I have on 18's right now and was thinking, if I go back to the stock 16's it'll improve the gas mileage a bit.
During the week I rarely ever hit traffic, I drive home when there is minimal traffic to no traffic at all. As for city driving, i usually drive stop and go for around 10 miles a day.
My question is, isn't it better to have the 18's on if I'm never in traffic and all the miles are freeway miles? My hypothesis is that lighter tires will be better for stop and go since it will take less amount of force to get the tires moving from a stop and go. And it would be better for freway with the 18's because it's in motion. When thinking about the physics, wouldn't a heavier object already in motion take less force to move it since it would have more momentum opposed to a lighter tire? Tell me I'm crazy and that the lighter tires will improve gas mileage and be better
