(1) Based on an internal treadwear test conducted on public roads versus the Bridgestone® Potenza™ RE980AS Pole Position™ (-29%), Continental® ExtremeContact™ DWS06 (-12%), Pirelli® P ZERO™ ALL SEASON Plus (-25%), and Goodyear® Eagle® Exhilarate™ (-23%) in tire size 245/40ZR18, using 2018 BMW 320i. Actual on-road results may vary.
(2) 4% better dry braking, 5% better wet braking, and 10% more snow traction compared to the Michelin Pilot Sport A/S 3+. Based in internal braking and snow tests conducted in tire size 245/40ZR18, using a 2015 BMW 328i. Actual on-road results may vary.
(3) Based on internal wet braking tests from 50 mph in tire size 235/45R18 XL using a 2020 Tesla Model 3 Performance comparing the Michelin Pilot Sport All Season 4 tire versus the Goodyear ElectricDrive GT tire and Pirelli P ZERO ALL SEASON Plus ELECT tire. Actual on-road results may vary.
(4) Based on internal dry handling testing in tire size 235/45R18 XL using a 2020 Tesla Model 3 Performance comparing the Michelin Pilot Sport All Season 4 tire versus the Goodyear ElectricDrive GT tire and Pirelli P ZERO ALL SEASON Plus ELECT tire. Actual on-road results may vary.

>> The sizes shown are average design values for tires measured on specified measuring rim widths. Some tires may vary from this value by +/-3% of the section height (affecting overall diameter), and +/-4% of the section width.
>> Section width varies approximately 0.2" (5mm) for every 0.5" change in rim width.
>> Tread patterns are often tuned to accomodate different tire widths. Tires for a particular dimension of a given tireline may vary in appearance from the tire shown in the photograph.
WARNING: Serious or fatal injury may result from tire failure due to underinflation or overloading. To ensure correct air pressure and vehicle load, refer to vehicle owner's manual or tire information placard on the vehicle. Serious injury or death may result from explosion of tire/rim assembly due to improper mounting. Only tire professionals should mount tires and they should never inflate beyond 40 psi to seat the beads. Before mixing types of tires in any configuration on any vehicle, be sure to check the vehicle owner's manual for its recommendations.
DANGER: Never mount a 16" diameter tire on a 16.5" rim.
DANGER: Never mount a 17" diameter tire on a 17.5" rim.
Inflation pressure increase must not exceed the maximum pressure branded on the tire sidewall. When a customer requests a replacement tire with a lower speed rating than the original equipment tire, you must clearly communicate to him or her that the handling of the vehicle may be different, and that its maximum speed capability is limited to that of the lowest speed-rated tire on the vehicle. Exceeding the lawful speed limit is neither recommended nor endorsed.
For high-speed driving, additional inflation pressure and possibly reduced tire loading and/or upsizing is required. In the absence of specific recommendations by the vehicle manufacturer, use the following guidelines based on those in the European Tyre and Rim Technical Organization Standards Manual.
For speeds over 160km/h (100 mph), load and inflation must be adjusted according to the table below.
Y-Speed Rated Sizes:
Maximum Speed (mph) 118 124 130 136 143 149 155 161 168 174 180 186
