I bought a set of VX rims and new tires for my civic this past week...
New tires: 155/80/13 OE tire size: 165/70/R13
1) more narrow
Pro: less rolling resistance (better FE)
Con: less traction 2) taller tire
Pro:higher final gear ratio (better FE)
Con: Speedometer will read 7% lower than actual, more sidewall flex during cornering 3) lighter wheels
Pro:less rotating/moving mass (better FE)
Con: costs more than steel rims, Al alloys are more prone to damage. 4) higher tire pressure (50 PSI cold)*
Pro:lower rolling resistance (better FE), longer life
*tire specs: Max tire pressure (cold): 44 psi, Max Load: 963 lbs.
...since I'm no where near the max load, I'll probably run the tires around 50 PSI...this should also help w/ FE by reducing rolling resistance.
I got the wheels for $200 and the tires for $130 (tirerack.com)...I spend around $200/tire for my 350Z - I love the civic !
2 of the new civic tires are as wide as 1 of my 350Z tires!!!:icon17:
here's the tires mounted:
*if you're in the Seattle area, check out: http://www.tightntidyracing.com/Tire_Services.html $50 for 4 wheels mounted/balanced.
These guys are great - they do it out of their garage as a side business...they're super knowledgeable, nice people, and very fast autoXer's...plus their prices can't be beat!
Nice deal on the VX wheels! Does the new tire size throw your spedometer off a little? So you got a FE car (civic) and JFF car (Just For Fun, 350Z). Nice!! I wish my other half would let me do that. She doesn't thing a 2,500 car would last to long. But, I especially like the eg hatches. Definitely on my want list of cars to have.

After you enter your OEM or other "base" size, it lets you see other sizes and exactly how close they match your OEM overall diameter. Same rim or other rim diameters. Should be ideal for those contemplating tire size changes.
Currently getting +/- 50 mpg in fall weather. EPA is 31/39 so not too shabby. WAI, fuel cutoff switch, full belly pan, smooth wheel covers.
