HOW TO FIND OUT TIRE SIZE
These are series of numbers and characters printed on the side of the tire. Usually for the modern tires the size almost always presented this way: 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. By deciphering these numbers you can find the exact tire chains for your needs.
TIRES YOU NEED TO CHAIN UP
The vehicles drive tires are the tires on which tire chains should be installed. On front-wheel drive cars you should chain up two front tires, of course if you have rear wheel drive vehicle you only need to chain up two rear tires. Now what if you don’t know what type of drive system on your car, you only have to check out the vehicle manual. Now if your vehicle is all wheel or four wheel drive, you are only going to have two tires chained up, always check the owner’s manual for advice on which axle to chain up. If you want maximum safety and reliability on your 4WD vehicle, chain up all tires of your vehicle.
Under normal driving conditions, 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 you only install snow chains on the front tires, the rear of the vehicle can swing during braking and driving. If you only put car snow chain on rear tires, you will find the vehicle steering ability is limited. To get this balance back, you should put snow chains on all tires, driving or not. Remember that traction devices are sold in pairs, if you want to cover both axles on the vehicle, you need to get at least 2 pairs. Don’t forget there are truck tire chains and passenger car tire chain , the truck tire chains usually are stronger and more expensive than car tire chains.
