Okay guys, I'm on a quest for 50MPG while trying to maintain 70MPH on the freeway. I know this is going to be very hard to do considering the 70MPH speed. I know that dropping speed by like 15MPH would probably get me my goal, but in Houston, everyone hauls ass. I'm getting better at not caring about this, but it's tough...

Okay for my next mod, do you guys think switching from a 195/50/15 to a 185/70/14 would be a wise choice? I plan on running them at a very high PSI to maximize rolling resistance. My current wheels are RPF1's and I'd be going to 14" steelies. I'm not getting rid of the RPF1's, I sort of want a spare set of Honda wheels anyhow....

Thanks in advance guys!! Oh BTW, I would plan on putting Mooneyes on these wheels for better aero...
