You can also move to a smaller diameter wheel. That will improve rotational inertia even more, along with usually being lighter due to the smaller size.
This is an upgrade I'm considering, downsize from my heavy 16" alloys to a 15" sport wheel. Stock rims are 17 lb each, Konig Helium 15" are 11 lb and cost under $100 each. I'd love a set of TE37's but the price...  |
BUT not reducing the overall diameter of the tire.
infact please consider increasing the overall diameter of the tire. (many threads on this topic.
