Sand Tires Unlimited Smoothee Tires 8.50 x 15
If your vehicle has too much wheel travel and too small of a tire, when you launch the vehicle and come down on a hard landing, you're going to bottom out the vehicle on the ground. If you buy the correct diameter tire to compensate for your wheel travel and don't have enough horsepower and torque to turn the tires, then you're going to have a miserable time in the dunes with your engine bogging down.
For front sand tires, you're going to need to know if the tire will rub your car when you turn all the way left or all the way right. If you don't have tires yet, turn your steering wheel all the way to one side. Measure from the center of the spindle towards your chassis and double that dimension. For example, if from your spindle to your chassis you have 15" then a 30" diameter tire is going to rub the side of your vehicle and you'll need something smaller in diameter or you're going to have to limit your turning radius.
Now let's figure out what your wheel travel is. See below diagram. If you don't have tires yet, collapse the suspension all the way. Measure from the center of your spindle or axle to the bottom of your chassis. Take that dimension and double that dimension. For example, if from the spindle or axle to the bottom of your chassis, you have 15" then a 30" diameter tire is going to be too small and if you launch the vehicle, you're going to bottom out the car on the ground. You would want several inches from the bottom of the chassis to the ground at full compression because the sidewall of the tire is going to compress if you come down from a hard landing.
After you figure out the diameter of tire that you'll need, the next big question is, do you have enough horsepower and torque to turn these tires?
Smoothee front sand tires are designed to offer the best flotation and lowest rolling resistance in sand thanks to its round, treadless design. This design prevents the front end of a buggy from digging into the sand while accelerating or turning, which helps maintains your momentum. Smoothees also throw the least amount of sand which is ideal for cars with little or no side body panels. Smoothees work well on lightweight cars with low to medium horsepower and are ideal for sand dragsters, and sand hill climbers.
