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.
  • Factory fitments or vehicles that specifically require XL-rated tires.

Think twice if you need

Quick Specs

  • Size: 245/45R18
  • Brand / Model: Nitto NT-555 G2 – Performance
  • Season: Summer
  • Vehicle Type: Passenger
  • Load / Speed: 100W (Load index 100 supports up to 800 kg per tire; speed rating W rated up to 270 km/h)

245/45R18 Nitto NT-555 G2 – Performance

XL (Extra Load) — built to handle higher inflation pressures and heavier loads than a standard-load tire of the same size.

What these tire specs mean

  • Load index 100 means each tire can carry up to 800 kg. Check your door jamb placard — the tire needs to meet or beat the load rating your manufacturer specifies.
  • Speed rating W is the maximum sustained speed this tire is designed to handle under proper conditions. That works out to 270 km/h under correct load and inflation — not a target, just the rated ceiling.
  • UTQG 320 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.
  • 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.

Where this tire fits in

What does the 245/45R18 tire size mean?

Break it down and 245/45R18 tells you three things: the tread is 245 mm wide, the sidewall stands at 45% of that — about 110 mm of rubber between road and rim — and it fits a 18-inch wheel. You’ll find this size most often on mid size SUVs, crossovers, and sport sedans.

The 100W on the Nitto NT-555 G2 – Performance breaks into two numbers: load index 100, meaning each tire carries up to 800 kg, rated to approximately 270 km/h; and speed rating W, rated to 270 km/h under proper load and inflation.

Is the 245/45R18 Nitto NT-555 G2 – Performance 3PMS rated?

No — the Nitto NT-555 G2 – Performance doesn’t carry the 3PMS symbol. If Quebec winter compliance or severe snow traction is a priority, you’d want a tire that does.
