A good fit if you

  • Warm weather grip, responsive steering, and performance handling — what summer tires are built for.
  • Drivers who already swap to a dedicated winter set when temperatures drop below 7°C.
  • Vehicles set up for run flat tires — compatible suspension and a working TPMS.
  • Factory fitments or vehicles that specifically require XL-rated tires.
  • Electric vehicles, where battery weight, instant torque, and road noise put extra demands on the tire.

Think twice if you need

  • Winter driving — summer tires harden in the cold and won’t satisfy Quebec’s winter tire mandate.
  • Anyone who wants one set of tires to cover all four seasons in Ontario or Quebec.

345/25R21 Michelin Pilot Sport 4 S – EV Compatible Performance Summer

Run flat design keeps you moving after a pressure loss — requires a compatible vehicle and a working TPMS.

What these tire specs mean

  • Load index 104 means each tire can carry up to 900 kg. Check your door jamb placard — the tire needs to meet or beat the load rating your manufacturer specifies.
  • Speed rating Y is the maximum sustained speed this tire is designed to handle under proper conditions. That works out to 300 km/h under correct load and inflation — not a target, just the rated ceiling.
  • UTQG 300 AA A is a manufacturer-assigned grade for treadwear, traction, and temperature performance. Useful for comparing within the same brand — but it’s not a mileage guarantee, and ratings aren’t standardized across manufacturers.
  • Summer tires are built for maximum warm-weather grip — dry and wet roads where compound stickiness and tread design matter most. They harden in near-freezing temperatures and are not suitable for Ontario or Quebec winter driving.
  • XL means Extra Load. These tires run at higher inflation pressures and handle more weight than a standard-load tire of the same size. If your vehicle’s factory spec calls for XL, that’s what you need — swapping to standard load can affect ride, handling, and safety.
  • Run flat tires are reinforced to support the car’s weight after losing pressure, so you can drive a limited distance to get help. They only work on vehicles designed for run flats — compatible suspension and a working TPMS — so they’re not a drop-in replacement on most cars.
  • EV Compatible means the tire is designed with electric vehicle demands in mind — higher load capacity for battery weight, reinforced sidewalls for EV torque, and compound choices that balance rolling resistance and road noise.
  • Vehicle type indicates the service category this tire is built for — passenger car, light truck, commercial, or other. Matching the right category matters for load capacity, handling, and safety.
  • Warranty coverage is backed by the manufacturer and applies under normal use — regular rotations, correct inflation, and proper alignment. Keep maintenance records if you ever need to make a claim.

Where this tire fits in

The 345/25R21 Michelin Pilot Sport 4 S – EV Compatible Performance is a summer tire, built around a 345 mm section width for a 21-inch wheel.

In practical terms, this size gives you a 25-series sidewall of about 86 mm paired with a 21-inch wheel diameter — confirm this against your current tire’s sidewall marking before ordering.

Worth noting on the spec side: this tire carries run flat construction, an XL extra load rating, load index 104 and speed rating Y (~300 km/h), UTQG 300 AA A when provided by the manufacturer.

About the 345/25R21 tire size

The 345/25R21 breaks down into three numbers:

  • 25 — sidewall height as a percentage of the tread width (roughly 86 mm of rubber between road and rim)
  • R21 — radial construction, for a 21-inch wheel

The 345/25R21 size is commonly found on performance vehicles and heavy duty trucks. Replacing a set? The full size marking is on your current tire’s sidewall — confirm width, profile, and rim diameter all match before you order.
