22-inch Tyre Buying Guide

Tyres are generally considered the most important component on any vehicle. Tyres transfer power from the engine to the road and ensure the braking and steering systems are able to do their jobs. Manufacturers and engineers invest time and money into matching vehicles with tyres that give a quality ride and provide optimum performance.

But car enthusiasts are rarely satisfied with OEM tyres and many enjoy the look and benefits of replacing tyres and rims with larger aftermarket options. Known as plus-sizing, this trend has created a large demand for oversized 22-inch tyres on everything from SUVs and sedans to off-road vehicles. Gain an understanding of how tyres are sized and rated and get to know the different types of 22-inch tyres available before committing to changing the wheels on a car or truck.

Evolution of Tyres

One of man's greatest inventions, the wheel, has been around since roughly 3500 BC. From its origins as a solid, curved piece of wood, to the steel-belted radial tyres commonly used today, the wheel has transformed in every way except its shape. The first turning point in the history of the wheel came with Charles Goodyear's discovery of the vulcanisation process, a process in which rubber is transformed from its sticky, raw form to a firm pliable material by heating it with sulphur.

These early solid rubber tyres paved the way for Robert Thompson and John Dunlop to experiment with pneumatic, or air-filled rubber tyres. Over the decades, tyres evolved from two part designs with an inner tube and an outer casing, to bias-ply tyres, to today's steel belted radials, which first appeared in Europe in 1948.

OEM Tyres

The OEM, original equipment manufacturer, tyres that come on any new vehicle are engineered to work with the wheels and the suspension of that vehicle to provide a smooth, quiet ride while offering good handling and durability. Tyre manufacturers and automobile companies spend time and money to ensure every make and model comes off the production line with tyres that match its specifications and capabilities. The key to a smooth, safe ride is a tyre that fits properly. Tyres are sized using a complex system of measurements and ratings, and owners should gain a basic understanding of this system before swapping the factory tyres for a different size.

Aftermarket Rims and Tyres

Whether the motivation is to improve the appearance of a car or to replace tyres that are worn out, at some point every car owner needs a new set of tyres. When shopping for tyres, car owners need to consider not only the type of driving and climate, but the performance capabilities of the vehicle. Replacing OEM tyres with ones that are sized and rated similarly is generally a straightforward process. Switching to larger diameter, 22 inch tyres requires a bit more work. Owners should arm themselves with some background knowledge on tyre sizes and specifications in order to find tyres that fit properly and provide a safe ride.

Finding the Right 22-inch Tyres

Finding the right 22 inch tyres is a matter of deciphering tyre size designations and understanding tyre specifications and types. Consumers need to know not only the desired tyre diameter, but section width, load capacity, speed rating, and aspect ratio.

Tyre Size Designations

Every tyre has an alphanumeric code moulded into the sidewall that gives size and specification information. Most tyres follow the ISO metric sizing system. The ISO system is universally recognised and follows a standard pattern to detail all the important specifications of a tyre. As an example, a tyre marked with the code LT265/35R22 110H indicates a tyre that is designed for a light truck (LT), has a section width of 265 millimetres, an aspect ratio of 35, fits a rim diameter of 22 inches, and has internal radial construction (R), with load index 110 and speed rating H.

Section Width

Section width, the width of a tyre from the widest point on the inner sidewall to the widest point on the outer sidewall, is the first number listed on the tyre designation. It generally follows the letter code giving the service indicator, although not all tyres list the service indicator.

Aspect Ratio

Immediately following the section width and separated by a forward slash is what is known as the aspect ratio of a tyre. This is also referred to as a tyre's series or profile, and gives the tyre's sidewall height as a per cent of its section width. For example, an aspect ratio of 75 means the tyre's sidewall is 75 per cent of that tyre's section width.


The diameter of the wheel and inside rim of the tyre is listed as a two digit number following the aspect ratio. While rim size is most commonly given in inches, there are a few tyres that list rim size in millimetres. This number is always 22 on 22-inch tyres.

Tyre Specifications

Along with the various measurements, each tyre is marked with a number of important specifications. This additional information includes the type of vehicle the tyre is designed for, the weight a tyre can carry, and the top speed for which the tyre is rated.

Service Type

Preceding the section width is a one- or two-letter code that indicates the intended service or type of vehicle the tyre is designed to fit. Several service types and codes are listed in the chart below.

Service Type

Description of Intended Use


Tyre designed for passenger vehicles using the P-metric system, Euro-metric tyres do not use this indicator on their passenger tyres


Tyres designed for light trucks


Indicates a tyre that is a temporary spare


Special trailer service tyres for boat, car, or utility trailers


Placed on the end of size designation on Euro-metric tyres to signify tyres for commercial or delivery vehicles

The "P" designation is the most common tyre service type seen. Although Euro-metric and P-metric tyres have a few small differences in their service type codes, both systems are universally recognised.

Load Index

Following the size markings on a tyre is a separate code that gives the service description. The numerical code consisting of either two or three digits is the load index. These numbers indicate the maximum load carrying capacity of the tyre.

Speed Rating

After the load index is a letter that correlates to the maximum safe speed for which that tyre is rated. Speed tests are performed with tyres inflated to maximum pressure and while carrying a full load. Always replace OEM tyres with tyres that have an equivalent or higher speed and load rating.

Choosing the Right Type of 22-inch Tyre

Choosing the right 22-inch tyres means selecting a tyre that is the right size, has the right service type and description, and is designed for the intended use. Tyres made for street use are rated differently than tyres rated for racing, and there is a vast difference between snow tyres, wet weather tyres, and off-road tyres. Be sure to choose a tyre based on its intended use, and then locate a tyre of the proper size made for that purpose.

Buying 22-inch Tyres on eBay

Shop eBay to find an assortment of tyres and wheels from a variety of manufacturers. Consumers can search eBay's extensive inventory of car and truck parts and accessories to find a single replacement tyre, a set of 22-inch tyres, or to purchase a complete wheel and tyre package. Shoppers looking for anything from performance racing tyres to off road truck tyres appreciate the convenience and value that eBay offers. Although a number of sellers offer free shipping, buyers can also limit a search to local listings with free pickup. Consumers on the hunt for bargains can search eBay Deals to find specially priced merchandise.


Whether increasing the size of a stock tyre or simply replacing 22-inch tyres on an oversized off road vehicle, selecting the right ones can be a challenge for someone who is not familiar with the size and rating markings on tyres. Choosing 22-inch tyres is a matter of matching the rim size to the tyre diameter and ensuring the service type and ratings on the tyre match the vehicle manufacturer's recommendations. If modifications were made to the vehicle prior to plus-sizing the rims and tyres, owners need to take those changes into consideration when replacing the tyres. A bit of knowledge regarding tyre sizing and ratings goes a long way toward ensuring a safe, comfortable ride for everyone.
