How do I know I'm getting the right size for my car? Shouldn't I be concerned with front or back wheel drive?
According to Google, your vehicle has front wheel drive. Therefore, most chain, cable, or AutoSock companies say that you only really need traction devices on the wheels that do the bulk of the work. Your front tires do the work in this scenario according to Google. Therefore, you want to check the size of your front tires to make sure you get the correct size for them.
What else should I know?
You should not drive over 30 mph with the AutoSocks installed on your vehicle. You risk damaging the AutoSock and not getting the lifetime value you would normally get out of them. You also cannot add more AutoSocks on your vehicle to negate the 30 mph value. No matter how much AutoSocks you have on your vehicle your ability to ride quickly and still have fully functioning AutoSocks is still limited to 30 mph. It is actually 20 mph if you are driving a commercial vehicle, however, your Kia Soul Exclaim is not a traditional commercial vehicle.
