Which tires should I use on my Vision?

1．Tire Selection
There are 2 types of tires, foam and rubber.
Foam tires are all slicks, meaning they do not have any tread pattern in them. Foam tires come in different shores or hardnesses. Shore ratings, or tire hardness/durometer, are usually 30 to 45 for 1/10th on road sedan cars. The lower the number, the softer the tire, the higher the number, the harder the tire. Different types of surfaces, track conditions, type of car, and a host of other variables determine the best shore rating to use. Always use the hardest compound possible without compromising handling and grip. The diameter of foam tires will also affect handling and grip. In general, smaller tires will make a car react quicker to steering and throttle input, while bigger tires will make the car easier to drive (but not necessarily faster.)
Rubber tires are available in slick and treaded forms. Nearly all rubber tires require the use of an insert. Rubber tire shore ratings differ between manufacturers, but generally range from soft to firm. You can change the handling of a tire by changing the insert, or by trying different inserts with different tires. This problem has been addressed by some manufacturers by combining the molding the insert into the tire. For example, the Medial Pro IAS tires use a honeycomb type of molded insert, which is actually part of the tire.
So which tire works better? There is no clear cut answer to this question. For most carpet tracks and "prepared" road surfaces, foam tires will work better. For most concrete surfaces rubber tires work better. On most "unprepared" surfaces (parking lots, street, local hobby shop tracks), either one may work, you'll have to try both to find out. |
