Short answer: What do the tire size mean?
The tire size refers to standardized measurements of a tire’s width, aspect ratio, and diameter. The first number indicates the width in millimeters, the second represents the aspect ratio as a percentage of sidewall height to width, and the third is the diameter in inches.
How to Understand Tire Size: A Step-by-Step Guide
Tire size is important not only for the performance of your vehicle but also for safety. Understanding tire size may seem like a daunting task, but fear not! This step-by-step guide will make it easy to decipher those mysterious numbers and letters on your tires.
Step 1: Identify the Tire Type
The first step in understanding tire size is identifying what type of tire you have. There are three basic types:
– Passenger car tires (P): These are designed for use on cars, station wagons, SUVs, and some light-duty trucks.
– Light truck/SUV tires (LT): Designed for towing and hauling with larger vehicles such as pickups or vans.
– Metric/High Flotation/Flotation Wide Base Tires (ST-METRIC ):Commonly used in trailers
Step 2: Read the Numbers on Your Tire Sidewall
Once you’ve identified your tire type, take a look at its sidewall where all relevant information is written including:
Width – represents the width measured from sidewall to side wall can be expressed using mm or inch e.g P215/55R17 means a width of 215 millimetres.
Aspect Ratio( / ) – The aspect ratio is represented by two numbers separated by “/,” it indicates a percentage representing how high the sidewalls are compared to the width.The example above shows that this number would mean that the section height would be approximately 22% visible from profile view compared to the tyre’s section Width(PRINTED ON THE TYRE).
Construction(Tyre design) – Indicated with either an R or D mark on most tyres represent Radial design and Diagonal Bias ply respectively.
Diameter – shown after “R” replacing hyphen between rim diameter measurement expressed inches.And Diameter value helps determine Rim specification generally separates them from different choices available say between spoke wheel style vs solid disc alloy wheels variant.e.g P215/55R17 93H will mean that the rim diameter should be around 17 inches in total.
Load Index – provides an indication of how much weight a tire can safely carry under normal driving conditions is represented by two or three-digit for PSI and the maximum load capacity it could handle. If such numbers Missed with Load index(AMOUNT), one needs to check guidelines provided in manufacturers manual according to required load recommendations related to Car Model, Version Year Specification etcetera.
Speed Symbol: A shorthand indicating the maximum safe speed on which your car may go driven using those specific tyre types at relevant loads assigned While expressing values ranging From N (87 mph) up-to Y Z (186 mph +).
Step 3: Determine Your Tires Recommended Air Pressure
Familiarizing yourself with your tires’ air pressure recommendation helps keeping them well-inflated also contribute toward maximizing fuel efficiency as well minimizing stopping distance can quickly wear off edges requiring frequent maintenance Shorter gaps than usual notice type deterioration over time. Confused about where specific inflation instructions located? Often they are printed inside driver-side door panel detailing what PRESSURE(Pounds per square inch) recommended list available tyres compatible enough match requirement you need.
