That's what you're setting this car up for, right?

Also the issue is more complicated that simple weight. Mass distribution of the 15's - more mass toward the outside - could potentially be less favourable than 13's or 14's. (Someone feel free to correct me on that - just something I read elsewhere that makes sense.)
Yes, I do like 90% highway with this car.

Oh and BTW, I got the 14x5.5" and I've already mounted them on the car. They fit great, now onto some Moon Eye covers...

I've found them online for like $85 for the stainless steel ones, anyone know of anything cheaper?

And BTW, Firestones on these wheels can take 44psi. What MPG difference would it make from 36PSI to the 44PSI? I guess only real world testing will tell, considering all the other variables... I try to drive as consistently as possible so my numbers are the least amount skewed....

Also, what size tire should I put back on these?? And if there is a 14" tire recommendation, please let me know. I've been looking at 175/70/14...

EDIT: There seems to be no difference in accelaration, and considering I don't drive fast anymore, it really doesn't matter....
