This listing is for new Bridgestone Potenza S001 RFT 225/40R18 88Y BSW Tires. Manufacturer part number: 023869. The Bridgestone Potenza S001 RFT (Run-Flat Tire) is a Max Performance Summer self-supporting run-flat tire made as Original Equipment to come with BMW 3 series sedans beginning with year 2012 model with F30 chassis. This also features Bridgestone Side Support Run-Flat technology improved sidewalls that allows you to drive temporarily in 50 miles at 50 mph even after a puncture and complete air pressure loss. This also provides great performance in wet and dry driving conditions. Like all summer tires, the Potenza S001 RFT is not made to be driven in very low temperatures, like in icy or snowy roads.

This has an asymmetric design with large outboard shoulder, central circumferential rib, and interlocking tread blocks to maximize dry road steering responsiveness, cornering accuracy, and stability when speeding. Its high-angle lateral grooves in the intermediate ribs push water into the circumferential grooves to resist hydroplaning. The notches in the shoulders also help by dissipating water to the sides.

This has twin belts backed up by spirally wrapped aramid/nylon cord to strengthen the built that minimizes rolling resistance, gives durability in high speeds, and improves ride quality.

Note: Install these tires in sets of 4 only. Bridgestone recommends this to provide best handling characteristics and performance of tires. These may not be mixed with other models of tires.

Sidewall BSW
This describes the sidewall appearance. Examples include Black Sidewall, White Sidewall, and White Letters.
Load Index 88
The load index (LI) is a 2 or 3 digit number that corrolates to the maximum amount of weight the tire can carry. For example, a tire with a load index of 87 indicates that the tire can carry a maximim load of 1,201 lbs. In the case of our example the 87 identifies the tires ability to carry a maximum of 1,201 lbs. So 4 tires will carry a maximum of 4,804 lbs. Refer to your vehicle owner's manual for the recommended minimim Load Index. It is not recommended to install tires with a lower Load Index. By doing so, this could cause your tires to be overloaded thus potentially causing a blowout.
Speed Rating Y
Speed Ratings (SR) are based on laboratory tests and indicates the maximum speed the tire can achieve. These tests are based on limited time trials. Higher speed rating tires typically will yield better handling capabilities, but may often result in lower mileage. Refer to your vehicle owner's manual for the recommended minimum Speed Rating. It is not recommended to install a tire with a lower speed rating as it could affect the handling of your vehicle. It is important to note that speed ratings only apply to tires that have not been damaged, altered, under-inflated or overloaded. Additionally, most tire manufacturers maintain that a tire that has been cut or punctured no longer retains the tire manufacturer's original speed rating, even after being repaired because the tire manufacturer can't control the quality of the repair.
Ply Rating Not Available
Ply Rating is related to the max load capacity. This value can be defined with a letter or number. The higher the number/letter, the higher the load capacity.
To help consumers evaluate their tires, the U.S. National Highway Traffic Safety Administration (NHTSA) created the Uniform Tire Quality Grading System (UTQG). The UTQG rates tires are rated on their tread-wear, traction performance, and temperature resistance. The grade for each of these can be found on the sidewall of your tire (except for winter tires and certain light truck tires). Click here for more information.
Max Single Load(lbs) 1235 The maximum load this tire will support. Remember to multiply this number by the number of tires installed on your vehicle to get the maximum carrying capacity. This number is directly related to the Load Index.
Max Single Air Pressure(PSI) 51 The maximum air pressure this tire will support. This does not represent the amount of air pressure your tires should have at all times. Consult with your owner's manual to determine the best air pressure you should use for your vehicle.
Tread Depth 10.0 The amount of tread on the tire. Once the tire is worn to 2/32nds, it is considered fully used and should be replaced at that time. Most tires will have tire indicators in the grooves of the tire to help you determine when the tires are worn down to 2/32nds.
Tread Design Asymmetrical
Nondirectional - most common, same tread pattern on inside & outside of the tire. Can be rotated to all four corners of vehicle.
Asymmetrical - tread pattern is different on the inside to the outside of the tire, and must be mounted properly. Can be rotated to all four corners of the vehicle.
Directional tires - roll in only one direction, must be mounted properly. Once mounted they must remain on the same side of the vehicle, and only be rotated front to rear.
Rim Width Range 7.5-9.0 The approved wheel rim width range this tire will support.
Measured Rim Width 8.0 The recommended wheel width as recommended by the tire manufacturer to get the best wear us performance for this tire.
Section Width 9.06 The measurement from sidewall to sidewall.
Tread Width Not Available The measurement from one side of the tread to the other side of the tread.
Overall Diameter 25.08 The height of the tire when fully inflated.
