tires for my set-up?

[meep]

Hey i was wondering how well this size tires would work on my set up. I'm building an off-road kart and i'm going to power it with a 8hp honda . I'm not sure what size sprockets to go with cuz i don't quite understand the ratios or how to use the calculator. But i found these tires on sale and seemed like a good deal. Oh and i'm hoping to get over 20 mph with a good amount of torque. Thanks.

All you have to do is put the diameter of the tire, the max RPM of the motor, the amount of teeth on the sprocket thats going to be on the axel and the amount of teeth on the clutch. then hit convert.

how would i figure a better ratio for torque? rather than max MPH?

At a max of 20MPH, torque should be just ducky. Gear for 20. To gear for torque, just figure out how slow you're willing to go, and gear for it. The lower the gearing, the better the grunt.

thanks a ton toy story! Hopefully i'll be picking up my motor this weekend and my base frame next weekend.
