Maybe you should look at some aftermarket rims. You can get some insanely light 15" rims if you look around. Maybe you can pair them with some lightweight tires. Lol.
So basically you're pointing out that a smaller tire will weigh less. Don't forget tire compound, tread thickness, overall design, number of ply's.... pretty much every possible spec of a tire will change its weight/performance.
You could plot the data for rim sizes versus weight, and pair that to possible tire sizes, develop a modeling equation, and then calculate the derivative, find the local minimum, which indicates the lightest wheel/tire combination, and then you have successfully optimized the system!
But then your poor reaction time at the track far outweighs the detriments of having an extra rotating lb on your tires.
no to mention if you pick a hard a-- tire you won't have any traction, etc...
Basically what I'm trying to say is weight isn't your only concern! Not even your biggest.

Well yea, thats common knowledge, larger size = more rubber = more weight. But, who in thier right mind is gonna run 205 40 16 on a mx3? You would have wheelgap for a week and it would look ridiculous. 205 50 16 or 215 45 is the proper size. Anyways, your best off getting a super light rim (15" MAYBE 16" if you are lucky to find a set) and a NORMAL sized tire and some light lugnuts. If you have a low performance motor it really doesnt matter anyways, unless you are auto-x'ing or something
I agree with your statement. Although I was just asking for weight on oem wheels. lets just leave it at that lol.
