Continental ContiSportContact 5 255/45R17 98W — Ultra High Performance Summer Tire
SSR run-flat UHP summer tire for E60 5 Series and E63 6 Series — the factory-correct spareless run-flat replacement for these BMW executive models on 17-inch alloys. The E60 5 Series uses SSR run-flat as its factory standard, and this 255/45R17 preserves the handling dynamics BMW engineered into the E60 chassis. Run-flat reinforcement maintains drivability after pressure loss at speeds appropriate for reaching a service center. The ContiSportContact 5 remains one of the most trusted UHP summer tires in the market — chosen by BMW, Mercedes-Benz, Audi, and Porsche as factory-original equipment on their most demanding performance vehicles.
Dry Performance & Handling
Continental's asymmetric tread architecture positions rigid outer shoulder blocks for maximum lateral grip, delivering confident cornering on both technical roads and high-speed sweepers. A continuous center rib ensures consistent road contact under acceleration and braking, providing the linear, predictable steering response that performance driving demands. The compound's silica formulation maintains stable friction coefficients throughout the temperature range generated during sustained performance driving.
Wet Weather Safety
Four circumferential grooves create high-volume water evacuation channels that pump water continuously away from the contact patch. Angled lateral grooves and inner-tread sipes provide additional wet traction and micro-grip on damp pavement — maintaining braking and handling safety even as precipitation intensity increases. The compound chemistry balances wet friction with heat resistance for sustained high-speed driving.
High-Speed Confidence
Speed-rated construction provides structural integrity at the highest speeds production vehicles in this application are capable of reaching. Continental's belt package and carcass geometry resist centrifugal deformation at speed, maintaining contact patch geometry and ensuring predictable handling responses at all points within the performance envelope.
SSR — Self-Supporting Run-Flat Technology
SSR (Self-Supporting Runflat) tires feature reinforced sidewalls that support the vehicle's weight after a complete loss of air pressure. In the event of a sudden puncture, you can continue driving at reduced speed — up to 50 mph for up to 50 miles — allowing you to safely reach a tire shop or service center without stopping on a dangerous highway shoulder. BMW and other manufacturers configure select vehicles without a spare wheel specifically because of SSR technology. Your vehicle must be equipped with a Tire Pressure Monitoring System (TPMS) — always respond immediately to a TPMS warning when driving on an SSR tire after pressure loss. Do not exceed the post-puncture speed and distance limits.

Always verify your vehicle's correct tire size on the door-jamb label or owner's manual. For vehicles with OE-marked requirements (MO, AO, N0, MGT, MOE, *), confirm the correct approval marking before purchasing. Vehicles configured without a spare wheel require run-flat or ContiSeal tires — always replace with the same technology type.
