I am thinking that the tires generally weigh more then the wheels so I think it would be better for me to go with a 14" light weight wheel and buy a lower profile tire which would save weight
I think you'll find that the stock setup (13") is lighter, overall, than anything else you're going to come up with. And for multiple reasons cutting weight on tires/wheels is especially important.
There are many more good tires available in 185 60 14 than the 175 70 13
A lot of VXs seem to have 175/70-13, but the proper size is 165/70-13. I think using the proper size is probably a good idea. Tirerack has a couple of choices in the proper size.
I would stay with the stock over all diameter because then your speedometer is correct.
Yes. There are multiple reasons to stay with stock tires, in addition to the speedo issue. As someone mentioned, that VX gearing is already very tall. It doesn't need to be taller. When you make it taller (with tires that are literally taller), this will tend to make it a bit tougher to get the car moving in 1st gear (especially if carrying a load and/or climbing a grade). I think this could cause extra wear on the clutch.
I did pick up an extra set of VX ones for just around $100.
That's a great price. I also have an extra set of VX wheels, for snow tires.
By the way, I've heard that some of the GM and Saturn alloys, 15" 4x100, are very light for 15s around 12lb or so.
I remember The RoadWarrior..To understand who he was, you have to go back to another time..the world was powered by the black fuel & the desert sprouted great cities..Gone now, swept away..two mighty warrior tribes went to war & touched off a blaze which engulfed them all. Without fuel, they were nothing..thundering machines sputtered & stopped..Only those mobile enough to scavenge, brutal enough to pillage would survive. The gangs took over the highways, ready to wage war for a tank of juice
I have VX 13's in the front and 14" HX in the rear. Lookin to sell at least 2 of my spare VX rims $150, maybe all 4 VX 13"s if i can find another 2 HX rims. (san diego fyi). i like the broader choice of tires for the HX 14's myself.
These Mini Cooper R81 wheels are 15x5.5" and weigh 12 pounds. They're nicknamed "holies". They have a 4x100 bolt circle and a slightly larger centerbore than OEM hondas. I've seen them priced about the same as HX rims around here, roughly $250-280 a set.
"I think the extra mass and larger size from take off would be negated by the high amount of miles spent on the highway."
I think you'll be paying for the extra mass every time you accelerate (and not just from take off). Which is something you do a lot, if you do P&G.
If you want to save gas, making the wheel/tire assembly as light as possible is a really good idea. The people who designed the VX knew what they were doing. They sweated the details, and it's not an accident that it gets great mileage.
