wheel weight vs. wheel size.

[erlrich]

What do you think? Is bigger better?
Does anyone have experience testing different sizes?

I am compairing ITR rims in 17 vs 18 and 16.5lbs vs. 18.3lbs respectively.

Thanks for your thoughts and ideas,
Stephen

If you're talking ITR the class, then you're stuck with 17" wheels - unless you're building an RX8, in which case you can use the factory 18" wheels. Generally speaking however, I've always thought that lighter was always better when it comes to wheels, as long as the tire size you want to run are available for that size rim.
