Has anyone found a comprehensive list on the 'net offering not just the bare weights of manufacturer's & aftermarket wheels, but of the weights of tires as well? I'd also like one that lists the weights of the tire/wheel combination AS INFLATED with air. Not sure this exists. Looking to take my 175/70/13's upto 185/60/14 or 185/65/14 for the larger circumference...but I'll be damned if I'm going to add weight. Hell, I'm looking for the step up WITH a reduction in weight. Only problem is it may be a lot of homework before I find them. The size alone should yield me +6 MPH
Studied this when I used to race.
By far the lightest tires out there are Pirelli's.
Also look into Hankook tires. I beleive they have a continental series that is very lightweight.
It gets complicated, tire size, side wall etc....
I can definitely understand where u are going with this though.
On my old car i was running Volk te37s and wanted the lightest tire possible.
since the wheels were 11lbs for 16x8
anyways
I would google search it,
brand you want, tire size, then just type lbs
let us know what u find

Thanks...a lot! -both of you. With the size I increase to I'll essentially be fooling my speedo by ~6MPH. So on my weekend trip of 325 miles the car will think it went just 292.5. I can't say the MPG effect will be follow precisely in suit, as I'm probably overlooking a fair amount of physics herein, but as long as that larger circumferance wheel/tire combination is NOT heavier and doesn't lead to higher rotational inertia...then I see NO reason why my (effective) MPG won't increase. Plenty of people throw a larger wheel/tire combo on their cars, but they usually add significant weight along with it. I'm not even looking to wind up even...I'm looking to step up size AND reduce weight all in one.
I know what you mean about the TE-37's. Nice. The Racing Hart CPO-35's come in at 7.9 LBS for a 15 X 6 / 15 X 7 ...so I could only imagine where that rim (unavailable) in a 14 would weigh in at. At any rate, those things are pricey as all hell. I'd like to track down the Mazda Miata BBS rims (even just 2), which are very light. I did wind up finding a very comprehensive wheel site, with a calculator for the tire/wheel conversion & MPH changes. I'll post that in a quick sec. Now I'll have to check tirerack to see if they really do have those tire weights. That would be great.
