Would anyone happen to have an extra 4 wheels, just the rims would do, in order to conduct a tire test for the 1.5? Working with "asgard" and Deschwerks to find more possibilities and tire combinations for the 1.5. Rob @ Deschwerks has some ideas and tires with the right rotational values needed, but we need to put them onto some rims to play around ensuring there's no traction control issues. If there's a set of 4 rims I'm happy to put down a deposit on them while we're using them and will ensure they'll be treated with the best of care. Best if you live around the SF bay area for this to work out.
