Bridgestone Winter Blizzak WS 60 Snow Tires
Bridgestone Blizzak WS 60 winter tires come in a range of sizes.
However, many people fail to understand exactly what tire sizes mean. You can always go in and purchase the tires your owner's manual tells you to buy, but understanding what the different numbers mean helps you make an educated purchase. It's especially important if you purchase a car in a country that uses the metric system compared to the more common system of inches in the U.S.
Bridgestone Blizzak WS 60 Winter Tire Sizes Explained
When shopping for Bridgestone Blizzak WS 60 snow tires, you find a long row of numbers. It may look something like this: P245/45R17 95S. Using this tire size, discover what each section of the tire size means.
In the beginning of any summer, all-season or winter tire is a letter, usually P, LT, T or ST. Each of these letters informs you into the proper use of the tire.
- P = Passenger
- LT= Light truck
- T = Temporary/Spare tire
- ST = Special trailer (tires for boat, snowmobile and other trailers hitched to your car or truck)
Most Bridgestone Blizzak WS 60 winter tires are going to start with the letter P. In the example, the number is P245. This means that the snow tire is 245 millimeters wide. The distance is measured from one sidewall to the other.
Rim Size Must Match the Tires and Vehicle Rims
The next number is 45/R17. The first digit in this segment of the winter tire size covers the height of the tire from the tread to the rim. The “R” stands for radial, telling you it is a radial snow tire, usually “R” is the only letter you'll see because most tires use radial construction. The numbers that follow the “R” tell you the wheel diameter, in this case it is 17 inches. It's important that the wheel diameter is exact because a tire with a larger or smaller wheel diameter than what is recommended will not fit your 17-inch rims.
Speed and Weight Ratings
The final number in a winter tire size, 95S, is the speed and weight rating. “S” means the tire is capable of speeds up to 112 miles per hour. Going faster that that can cause serious damage to the tires because they will heat up too much and the steel belts will separate from the tread. Other letters include H (130 miles per hour max), Q (99 mph max), T (118 mph max) V (150 mph max) and Z (over 150 miles per hour.)
The number 95 is the load index rating given to the Bridgestone Blizzak WS 60 winter tire. This means each tire is capable of a maximum load of 1,521 pounds. To find out the total weight, multiply 1,521 by four and you should never make your car carry more weight than that final number. In this case, four 95S tires would allow you to carry 6,084 pounds including all passengers and the vehicle's weight.
