Currently, I'm running Yokohama geolandar M/T 35x12.5r17. I have a long trip coming up that is going to consist of mostly highway driving. However, I plan on doing a couple of moderate mountain passes.
My main question is will downgrading my tire size/weight to a 34" or 33" make a noticeable impact on the performance and fuel economy? Or do I just send it to the big boys? Fuel economy is the least of my worries because its a GX470 lol.
