FAQ

This is the Michelin Pilot Sport Cup 2 Connect tire in size 345/30ZR19 with a 109Y load and speed rating, a streetable track and competition tire designed for high performance sports cars and supercars.

Yes. It is a DOT legal semi slick tire designed to be driven on the street while still delivering track level dry grip and handling.

This tire carries a UTQG treadwear rating of 240, which meets the street category definition used by many racing associations while still prioritizing dry performance.

This tire is optimized for dry performance. Grip drops significantly in cold temperatures, standing water, and heavy rain, so cautious, reduced speed driving is recommended in those conditions.

Track Connect is an optional sensor system that mounts inside the tire and streams real time pressure and temperature data to a companion app, helping drivers dial in optimal pressures during track sessions.

A load index of 109 supports up to 2271 lbs per tire, and a Y speed rating supports sustained speeds up to 186 mph.

No. Michelin advises against mixing Pilot Sport Cup 2 Connect tires with Pilot Sport Cup, Cup Plus, Cup N-Spec, or Cup ZP run-flat tires on the same vehicle.

345/30ZR19 is a wide rear fitment found on high performance platforms such as the Porsche 911 Turbo and GT3 variants and similarly wide-track supercars that require an Extra Load rear tire.

Install Instructions

1. Confirm the tire size and load rating match the vehicle manufacturer's specification for the intended axle position
2. Have the tire professionally mounted and balanced by a qualified tire installer
3. Set cold inflation pressure to the vehicle manufacturer's recommended road use pressure before driving
4. For track use, begin at road use pressure and adjust hot pressure only after a steady run of laps
5. Inspect the outer sidewall regularly for wear indicators and adjust pressure if markings begin to disappear
