For the best in handling and ride comfort we recommend a 16" wheel from Team Dynamics. It is a high quality, low weight wheel that is made in the UK (not China). We have them in stock and recommend them to those that want a custom wheel for the smart, but also want a nice ride.
For those that want a more aggressive look and even better handling we recommend a 17" wheel. The ride on a 17" wheel will be rougher and a 16" is a good compromise.
Here is a link to the TD wheels:

As always we offer the lowest price guarantee on these and every wheel and accessory we sell.
If you have any questions please do not hesitate to contact me directly.
Thank you,
