      How to Understand Your Current Tire Size

      Knowing your Jeep's tire size can be essential information when it comes time to replace that rubber, or even if you ever decide to change wheels. And while a stock tire size is imprinted right inside the driver side B pillar, you may not know what if have if you are not the original owner.

      So here is some helpful information to assist you in determining what you currently have on the vehicle.

      First, the sidewall of your tire contains all the information needed to understand everything about that specific tire. All tires are required to have this information, regardless of the manufacturer brand name.

      Now, this information could read in a few different ways. For example, it could simply say 35x12.5 R17, or it may show as P265 75 R15. If it is the first listing, then here is the breakdown. That first number is your tire size at 35", and then the second number tells you the tire width at 12.5". That third reading is the tire type as radial and diameter as 17".

      The second listing is a metric set up, and is what is more common on factory-type sized tires. From left to right, the P indicates a passenger tire while 265 indicates the tires width in millimeters. That 75 is the tire's aspect ratio and simply means the tire's height is equal to 75 percent of its width. Finally, like the first set of numbers, that R15 means it is a radial tire and has a 15" diameter.

      For those who have the metric reading on their tires, you can simply plug that into the conversion calculator to determine the tire size, or find that corresponding reading on one of the below conversion charts.

      Metric measurement example: 225/70R15

      225 = Section width in millimeters

      70 = Aspect ratio (ratio of section height to section width)

      R15 = Rim diameter

      R = Radial Construction, B = Bias Construction, D = Bias Belted Construction


      Calculations for Measurements

      Tire Width: Section width divided by 25. 4 (Ex: 225 / 25.4 = 8.86")

      Section Height: Tire width times aspect ratio (Ex: 8.86" x 70% = 6.20")

      Overall Diameter: Section height times 2 plus rim diameter (Ex: (6.20" x 2) + 15 = 27.40")

      All tires are required to have certain information molded into the side of the tire in a location known as the sidewall.  Some of the information is self explanatory while other information requires a little knowledge to decipher.  The following will help you understand what this information means.

      Tire Type – This Defines the intended proper use of the tire. P indicates this is a passenger car tire while LT indicates the tire would be for a light truck with a heavier load rating.

      Tire Width – This is the width of the tire measured in millimeters from sidewall to sidewall.  An example might be 215 representing 215 millimeters.

      Aspect Ratio – This is the ratio of the height of the tire’s cross-section to its width. An example of this might be 65, which means that the height is equal to 65% of the tire’s width.  To calculate the aspect ratio, multiple the first number (e.g. 215) by the second number with a decimal before the number (e.g. .65).  Using the example numbers the tires aspect ratio would calculate as 215x.65=139.75 where 139.75 is the tires height in millimeters.  This is the height of the rubber from rim to tread on one side of the tire. 

      To convert the aspect ratio to a full tire height in inches, do this:
      Convert the above calculated tire height (aspect ratio) in millimeters to inches by multiplying the millimeters by .03937 (139. 75 x .03937 = 5.5 inches).  Then take the inches and multiply by two and add the rim size. Example: 5.5 x 2 + 15 (rim size in inches) = a 26 inch tall tire.

      Construction – This indicates how the how the tire was put together and will say much about the tires handling characteristics. R indicates the tire is a radial type tire.  For more information about what a radial is, click here.  B indicates the tire is a bias ply type tire.  For more information about bias ply type tires, click here.

      Wheel Diameter – This is the width of the opening in the tire where it would be mounted to a wheel.  This is measured from one bead across the opening to the other side of the same bead.  This measurement is in inches and an example would be 15 and indicates that this tire is for a 15 inch rim, or wheel.

      Load Index – This is a number corresponds to the maximum load in pounds that a tire can support when properly inflated. You will also find the maximum load in pounds and in kilograms molded elsewhere on the tire sidewall.

      Speed Rating – This is a number that corresponds to the maximum service speed for a tire.  See Chart for ratings.  Note: Speed ratings are specific for passenger car tires and not light truck tires.  Light truck tires (LT) are not speed rated. 

      Rating

      Maximum Speed
      Q99 mph
      S112 mph
      T118 mph
      U124 mph
      H130 mph
      V149 mph
      W168 mph
      Y186 mph
      ZAbove 149 mph

      Tire size replacement table

      Every motorist eventually comes to the moment when he wants to make a certain upgrade of the car. But any modification entails not only design changes, but also the improvement or deterioration of running gear. But is it possible to change tire sizes? Undoubtedly, this also applies to car tires with disks. Replacing tires and wheels is one of the most popular tuning manipulations. Everyone knows that wider and higher tires give the car solidity and attractiveness, even if the modified vehicle belongs to the budget category. But is increasing tire size really a good idea? Let's look at three options for replacing rubber with a factory dimension of full profile, low profile or extra low profile tire replacement options.

      To begin with, it should be understood that the native size is chosen by designers for a reason. It is formed based on the technical capabilities of the car, its traction and acceleration characteristics. Also, the initial size is affected by the shape of the car body, weight, and its purpose.

      Tire size is determined by three values, for example, in a tire with a size of 185 65 R14 they will be interpreted as follows:

      • 185 - profile width (not the tread!) in mm;
      • 65 - profile height in % of the profile width;
      • R14 - internal diameter in inches.

      Changes to certain parameters have consequences in terms of clutch quality. Moreover, each case is private, there is no specific rule on how this or that modernization will affect the ride. In case of a planned change, it is necessary to consult with a specialist. Below is a table of replacement tire sizes.
