Tire Size

Knowing the size of your tires is the key to ordering the right size snow chains. Most tire sizes will be listed on the side of the tire. The number will usually look something like this: P215/60R16. The first number, in this case “215”, is the width of the tire in millimeters. The second number, “60”, is the Aspect Ratio. This is the height of the sidewall as a percentage of the width. The last number, “16”, is the diameter of the wheel in inches.

Check your vehicle’s owner’s manual

Before you buy any tire chains, check your vehicle’s owner’s manual. It will list the maximum width and height of the tires that can be used with the vehicle, as well as the maximum size of the chains. Once you know these numbers, you can narrow your search for the right chain.

There are two ways to measure a tire – diameter and width. Tire diameter is the height of the tire from one end to the other. To measure width, lay a straight-edge across the widest part of the tire tread, not including any raised lettering or design elements.

Once you have these measurements, you can start shopping for chains. Most retailers will sell chains in sets of two, so you’ll need to buy two sets if you want to chain all four tires.

Find your tire size on the sidewall of your tire

To find your tire size, look for a series of numbers on the sidewall of your tire that looks something like this: P215/65 R15 95H. Every tire has a “tire size” printed on its sidewall. This number is a measurement that indicates the width of your tire in millimeters, the height of your sidewall as a percentage of the width, and finally the diameter of the wheel (excluding any decorative trim) in inches. In this example, your tire has a width of 215 millimeters, a sidewall height of 65% of 215 millimeters, and a wheel diameter of 15 inches.

Chain Size

There are a few things you’ll need to know in order to determine what size snow chains you’ll need. You’ll need to know the size of your tires, the width of your tires, and the thickness of your tires. With those three measurements, you’ll be able to determine what size chains you’ll need.

Use a snow chain size chart

Before you purchase a set of chains, it’s important to know what size you need. Each tire has a unique size, so you can’t just buy any old chain and expect it to fit.

The first step is to look at the sidewall of your tire. You’ll see a series of numbers and letters that look something like this: P215/65R15. The number you want to pay attention to is the second one, in this case 65. This indicates the width of the tire in millimeters.

Once you know the width of your tire, consult a snow chain size chart like the one below. This will tell you what size chain you need for your specific tire width.

Tire width (mm) | Snow chain size
145-195 | 6
195-225 | 8
225-265 | 10
265-305 | 12

Determine your chain size based on your tire size

Chains are available in many different sizes. To determine what size you need, start by looking at your tire size. Once you know your tire size, you can narrow your search for the right chains.

Most passenger vehicles will require either a 9mm or an 11mm link chain. Some higher-end vehicles may require a 13mm link. Most light trucks and SUVs will require an 11mm or a 13mm link chain.

The first thing you need to know is what size snow chains you need. To find out, look in your vehicle’s owner manual or on the driver’s side door pillar for a tire size label. The tire size will be listed as a series of numbers, such as 245/75R16. The first number is the width of the tire in millimeters, the second number is the aspect ratio, and the last number is the diameter of the wheel in inches.

Read the instructions that come with your chains

Most snow chains will come with detailed instructions on how to install them. These instructions will vary depending on the brand and model of chains you have, so it’s important that you read them carefully before attempting to install your chains.

You should also consult your vehicle’s owner’s manual for specific instructions on how to install snow chains on your particular vehicle. Many newer vehicles have special requirements or prohibitions when it comes to using snow chains, so it’s important to be sure you are following the manufacturer’s recommendations.

Follow the manufacturer’s installation instructions

Always follow the manufacturer’s installation instructions. Depending on the size of your tires and the type of chains, the process will vary. Generally, you’ll need to place the chains around the tire and then tighten them so they’re snug. Once they’re in place, you should be able to lightly tug on the chains and they shouldn’t come loose.
