Original Equipment tire sizes shown in search results for particular vehicles are determined based on the best information currently available to us from vehicle manufacturers and from manual inspection of new vehicles as they are released. Many vehicles have optional trim levels/packages that include different tire sizes. This "Additional Model Info" is listed for you to choose from in search results as well.
Since variations based on options or vehicle manufacturer changes may determine the Original Equipment tire size on your vehicle, always verify the size you are purchasing matches the tire size for your vehicle (usually found in the door jamb, glove box lid or gas cap door) or in the Owner's Manual.
If you are unsure what size is installed on your vehicle, please confirm the size as listed on the tire sidewall before placing your order.
The Optional Tire Sizes featuring different rim diameters we list for many vehicles are based on over 30 years of experience we have with plus size wheel and tire combinations. However, it is important to note that these optional tire sizes are based on vehicle specific wheel sizes/offsets offered by Tire Rack.
Directional tires will have a rotation arrow branded on the tire's sidewall. The arrow indicates the direction in which the tire should turn.
Unless they are dismounted and remounted on their wheels to accommodate use on the other side of the vehicle, directional tires are to be used on one side of the vehicle and are intended to be rotated from the front axle to the rear axle. If different tire sizes are used on the front vs. rear axle, the tires become location-specific and prohibit tire rotation unless remounted.
Proper tire air pressure is determined by the vehicle manufacturers and is set to best fine-tune a tireís capabilities to their specific vehicle make and model. The vehicle manufacturer's pressure recommendation can be found on the vehicle's tire information placard label, as well as in the vehicle owner's manual.

Yes. But keep in mind that many times when a vehicle is equipped with run-flat tires from the factory, a spare tire is not included. Some drivers opt to carry a full-size spare or a space saver spare tire. Another option is to carry a product like the Continental ContiComfortKit for temporary mobility in the event a tire is punctured.
Also note that when you first change from a run-flat to a non-run-flat tire, the installer will need run-flat capable equipment to remove the original tire. Many of our Recommended Installers have this equipment.
Because run-flat tires are so good at masking the traditional loss-of-air symptoms that accompany a flat tire, they require a tire pressure monitoring system to alert the driver that they have lost air pressure. Without such a system, the driver (even an experienced driver) may not notice underinflation and may inadvertently cause additional tire damage by failing to inflate or repair the tire at the first opportunity.
Tire Rack's Tire Warranty Rating is an overall rating given to tire warranties after subjectively evaluating their value for the consumer. Warranties are rated on a scale of 0-5 with 5 being the highest. This rating combines all of the aspects of each tire's warranty where applicable, including: mileage/treadlife, materials and workmanship, balance and uniformity, replacement tire cost, warranty duration and any special manufacturer's warranties that apply. See official manufacturers' warranty brochures for specific details.
Check your tires' tread depths. When a winter / snow tire has worn to about 6/32", itís ability to provide beneficial snow traction will start to diminish. While still legal at 2/32", a winter / snow tire has worn well past the depth where it provides beneficial snow traction. Also read: Tread Depth Ė Why Too Little is Never Enough
In Germany, some highways do not have speed limits and high speed driving is permitted. Speed ratings were established to match the speed capability of tires with the top speed capability of the vehicles to which they are applied. For example, an R-speed rated tire is designed for maximum speeds of 106 mph. Detailed information can be found in our tech article: How to Read Speed Rating, Load Index & Service Descriptions
When searching by vehicle, you can select the rating(s) based on your vehicle and intended use. When you choose "recommended" you will see the speed rating(s) appropriate for your vehicle. Numbers in parentheses indicate quantity of tires available and do not include winter or competition tire counts that are below your vehicle's recommended speed rating.
If you were to put winter tires on only the front or rear of your vehicle, you would create a vehicle with a split personality.
Leading automobile manufacturers such as BMW, Mercedes-Benz, Honda, Nissan and Toyota recommend in their owner's manuals that you install four winter tires for winter driving. By installing four winter tires, you maintain the most balanced and controlled handling possible in all winter driving conditions. It is imperative to keep the same level of traction at all four corners of the car; otherwise, the full benefits of ABS or traction control systems will be lost.
We tested mixed vs. matched tires on vehicles in the winter. Here are the results.
Refer to this drawing to see the various markings on a tireís sidewall. The tire identification number is shown middle left in the illustration and is essentially the tireís serial number. It is required when registering tires with manufacturers and is used for safety standard certification and in case of a recall. Read more in our tech article: Tire Identification Numbers
The load range (or load index) on a tire's sidewall helps identify its strength and ability to contain air pressure. Load ranges are identified in ascending alphabetical order for light truck/SUV tires (the further along the letter is in the alphabet, the stronger the tire and the greater amount of air pressure it can withstand and load it can carry).

When searching by vehicle, load ranges are shown in ascending alphabetical order. When you choose "recommended" you will see the load range(s) appropriate for your vehicle.
