Hello Blueknight/ Mike,
Thanks for replying, I found another tire, for the spyder, and they even come in the sizes to fit the threewheeled beast.
Hankook Ventus Rs3 or 4, reviews on these are quite good, it is not a fourseason tire like the q5, but only for summer
the smallest size they offer is 195/50R15, they should fit the front tho, but for the rear they offer 225/45R15, and that is just a tad less, in miles per revolution
