READ THE TIRE SIZE
There are series of numbers and characters can be seen on the side of your tires. On most modern tires, the tire size will look like this: P265/50R15, by reading this number we can conclude that the tire width is 265mm, aspect ratio is 50% and is mounted on a wheel which has a diameter of 15 inches. All of these numbers are critical in helping you to find the traction products that will fit your tire.
TIRES YOU NEED TO CHAIN UP
Usually you should choose the drive tires to chain up with tire chains . On vehicles with front-wheel drive this would be the two front tires, on vehicles with rear wheel drive this would be the rear tires. Say you have no idea about your vehicle’s drive system, you just have to check the manual of the vehicle. Now if your vehicle is all wheel or four wheel drive, and you only intend to chain up two tires, which axle should be chained up should be determined by the owner’s manual of your vehicle. To stay on safe side and retain as much of the normal handling characteristics of your 4WD as possible, install traction devices on all tires.
When you’re driving under normal condition, all wheels of a vehicle will have about the same amount of traction, creating a feeling of “normal” control during braking, acceleration and cornering. When driving under snow or ice conditions this balance will be distorted. If snow chains are installed only on the front tires, the rear of the vehicle can swing during braking and driving. If only the rear tires have the truck snow chain on, you will have limited steering ability of vehicle. To restore the balance, All tires should be chained up with same kind of snow chains. Since all tire chains are sold in pairs, if you want to cover both axles on the vehicle, you must purchase two pairs. As we can see, we have truck tire chains and car tire chains on the market, the truck tire chains usually are stronger and more expensive than car tire chains.
