Michelin Pilot Sport All Season 4 — 245/40ZR17 XL 95Y — Overview
The Michelin Pilot Sport All Season 4 in 245/40ZR17 XL 95Y is engineered for drivers who want a single tire that performs at the limit in dry conditions, inspires confidence in rain, and doesn't leave you stranded when the first snow falls. This isn't a compromised all-season masquerading as a performance tire — Chevrolet chose the Pilot Sport All Season 4 as original equipment on the Corvette, which tells you exactly where this tire sits in the performance hierarchy.
Michelin's proprietary tread compound is the real story here. In independent testing against the Bridgestone Potenza RE980AS, Continental ExtremeContact DWS06, Pirelli P ZERO All Season Plus, and Goodyear Eagle Exhilarate, the PSAS4 delivered up to 29% more tread life — a meaningful advantage when you're factoring long-term cost into the equation. Over its direct predecessor, the Pilot Sport A/S 3+, it posts 4% better dry braking, 5% better wet braking, and 10% greater snow traction, measurable improvements across every condition that matters.
Michelin conducted much of its validation testing using a BMW 3 Series in 245/40ZR18 — a close cousin to this 17-inch spec — making this a particularly well-suited fitment for BMW owners running E46, E90, or similarly dimensioned chassis. The XL construction and 95Y speed rating ensure the tire can handle the structural demands of a performance BMW without reservation, whether you're on a mountain pass or a wet highway on-ramp.
If you've been running separate summer and winter sets and are looking to simplify without giving up driving character, the Pilot Sport All Season 4 is the most honest answer on the market. It stays in its performance lane year-round, so you can stay in yours.
