SILICONE TIRES - The material of choice to improve a car's performance.
When choosing tires, you will need to know the *size that you require. You may be able to measure the diameter and width using a ruler, but callipers will make the measurement easier and more accurate. Also note that the ridge of the hub that holds the tires can be different sizes, so not all tires will fit all hubs, even if the outside dimensions are correct.
*Different profiles allow for minimum air gap under the car chassis.
Please Note: Care should be taken with silicone tires; due to their grip, they pick up dust and dirt much more easily than conventional rubber tires. Make sure to keep both your track and your tires clean.
