The Radar Dimax 4 Season 22545R17 94W brings a 225 mm width and 45% sidewall to 17-inch wheel setups, positioning it as an all-season choice for passenger cars.
It carries a load index of 94, supporting up to 670 kg (1477 lbs) per tire, and a speed rating of W, rated for sustained speeds up to 270 km/h (168 mph). This places it in the C1 category — an entry-level, budget-friendly class.
This model skips the reinforced rim guard found on some tires, so drivers should be mindful when parking near curbs. This is not a run-flat tire, so a spare or roadside assistance plan is still worth keeping on hand. It uses standard (non-reinforced) construction, which is sufficient for typical passenger car loads.
It’s suited to muddy and snowy surfaces and has been tested for winter performance.
The EU label breaks down to class D for fuel efficiency, class C for wet grip, and class B for noise at 72 dB — a moderate noise footprint, not particularly loud or quiet.
As useful as the EU label is, it doesn’t cover every factor — things like dry-weather grip, aquaplaning resistance, and tread wear fall outside the official scoring.
