Michelin Pilot Alpin PA4 ZP (*) 245/50R18 100H Run Flat

Overview
The Michelin Pilot Alpin PA4 ZP (*) is a performance, winter tire made for SUVs. This is the original equipment tire of select BMW vehicles.The tire offers exceptional winter-weather performance, thanks to the asymmetric tread design and the durable rubber compound. The large tread elements are able to provide a firm grip on snow and icy road surfaces, and by that improve winter traction. The special silica compound keeps the rubber flexible in harsh winter conditions. At the same time, the optimal grooves on the tread area actively resist hydroplaning by dispersing water and slush from the footprint. These elements guarantee the tire’s safe performance, even on ice- and snow-covered roads.This model is a run flat tire, which allows its limited performance for 50 miles in case of an air pressure loss. In other words, the strong internal structure supports the tire if air pressure decreases due to punctures or some other damage. This allows the vehicle to arrive at a nearby location, where the tire can be fixed. Run flat models should not be mounted on the same vehicle together with regular tires.The Michelin Pilot Alpin PA4 ZP (*) boosts its controllability. The asymmetric tread pattern maintains close surface contact at all times. It improves steering responsiveness and driving stability. The steering response time becomes faster and more precise to the driver’s commands, while the structure is secured against driving pressure. On the other hand, wide shoulder blocks, with special siping details, optimize cornering and maneuvering. These elements guarantee the driver excellent control over the vehicle.
