None of the above. I used the automotive formula because of the tires of the Spyder. I used the severe amount as recommended on the chart (11 oz front, 16 oz rear) because of the numerous castus thorns laying around in the desert. I bought 3 containers. I was lucky enough to have a distributor in San Diego and went to his house to get the Ride-On. The best of all that is that he installed it for free. No jack is necessary. Just remove the valve stim core, let the air out, fill the right amount, clean the inside of the valve stem, screw in the core, and air up. Go riding a few miles to distribute it inside the tires. You will experience a few minutes of "unbalanced tires", but no fear, it will smooth out. If you go to the Ride-On site and call their free number, they will provide you with the phone number of a distributor nearest you. Great service.
