🏮 How To Read Tyre Dimensions

The P/LT mark is often missing from tires, and the sequence starts with the tire width. In that case, the tire is almost guaranteed to be a P-Metric type. 2. Tire Width. P 155 /65R14 75T. Tire width is the first of the three dimensions you’ll find on the sidewall of a tire. The R means radial, as in the construction style, while the 16 means it rides on wheels with 16-inch diameters. 1. Metric, or tire type. 2. Tire width. 3. Rim diameter. 4. Speed rating. Generally speaking, a width of 25mm will work for most riders. They are widely recognized as the best compromise between comfort, weight and performance. Racers will opt for a smaller width, or if you’re tackling rougher roads, going up to 28mm may be the best option. In most cases, if you’re replacing a tire you can just look at the 55 refers to the profile of the tyre, or the distance between the wheel and the edge of the tyre, looking at it from the side. The number is the percentage of the width of the tyre. It is commonly known as the “aspect ratio”. So, the profile of our example tyre is 55% of 205mm, or 112.75mm. This number also increases in increments of 5. Sport quads—20 to 25 inches. Utility quads—24 to 28 inches. Factory mud or rock equipped quads—27 to 30 inches. Keep in mind that you’ll want to keep within a couple inches of your stock tire size. If you go too big, you’ll start to rub on your fenders (among other issues). If you go small—well, that’s just silly. 26 is you tire height. 10.5 is the width of your tire and 16 is the inside diameter for the rim. 10.5 is a little to wide for comfort on your stock rim. Maybe an 8.5 inch slick or get and 8 inch rim for the wider slick. Tire Size Description. The tire size is by far the most significant piece of information printed on a sidewall. Let's have a look at how to read it correctly first. The size of the tire will be represented as follows in most cases: P225/40/R17. Note: While the numbers will differ from tire to tire, the formatting will remain the same. Tyre size fitment guide. Use our guide to understand where your tyre width, tyre profile, Radial, load index, wheel diameter and speed rating is located on the tyre sidewall. Radial Tyres. Radial is a specific design of tyre where the sidewall and tread functions as two independent features. The layers run radially across the tyre. The same size bike tire could be found with different numbers in different countries. As cycling has become more global, a standardized approach was needed. While traditional sizing systems are based on the outside diameter of an inflated tire (measured in inches or millimeters), the ISO standard notation uses the diameter of the wheel bead On MICHELIN tyres, you can easily identify them by the little Michelin Man symbol that appears in several places on the sidewall of the tyre. When you see the Michelin Man, you know that the wear indicators are arranged in line across the width of the tyre. When the treads on your tyre are worn down to the same level as the wear indicators, the Dimensional Data Dimensions of tires are for tires on design rims. Dimensions on other rims are the same except for tire widths. Change tire widths 0.4" (10mm) for each 1" (25.4mm) change in rim width. 225/75R15 tires have a diameter of 28.3", a section width of 8.9", and a wheel diameter of 15". The circumference is 88.8" and they have 713 revolutions per mile. Generally they are approved to be mounted on 6-7.5" wide wheels for passenger tires and 6-7" for LT tires.
