I have 15'' not so light rims right now, the over all weight tire+rims are heavier than the stock ones, I will put them on a scale when I have a chance.
The test is still in progress, so far I noticed that I can go further when coasting down or on flat road.
According to this site I need to get 195/50R15 tires instead of 195/60R15 that I have right now. http://www.1010tires.com/Tools/Tire-...0R13/195-50R15
Here is my list of possible wheel swaps for 5th/6th gen Civics like ours, from my car's garage site:

Possible wheel swaps for gearing/weight advantages:
13" Civic VX 8 spoke (higher RPMs but only 9.7 lbs.)
14" Civic HX 8 spoke (approx 11 lbs)
15" Mini Cooper R81 Imola 7-hole (12.1 lbs)
15" Mini Cooper R86 star-spoke (15 lbs)
15" Mini Cooper R96 7-spoke (13.8 lbs)
15" Enkei Classic J-speed (14.1 lbs)
15" Acura Integra GSR (94-95, 16lbs)
Other size specs: Offset 35-45; bolt patter 4X100; lug size 12mmX1.5; hub center bore 56.1mm.

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
