The Riken All Season 22545R17 94W is an all-season tire built for passenger vehicles, with a section width of 225 mm, an aspect ratio of 45%, and a fit for 17-inch wheels.
With a 94 load index (up to 670 kg / 1477 lbs) and a W speed rating (up to 270 km/h / 168 mph), this tire falls into the C1 class, aimed at drivers looking for solid performance without a premium price tag.
No rim protection is built in here, meaning the wheel edge isn’t specifically shielded from curb contact. This is not a run-flat tire, so a spare or roadside assistance plan is still worth keeping on hand. This is a standard-build tire rather than a reinforced one, in line with typical load needs for passenger vehicles.
It performs on muddy and snow-covered roads and carries winter-suitability testing.
Its EU label ratings come in at D for fuel efficiency, C for wet grip, and B for rolling noise (70 dB), placing it in the mid-range for road noise.
Keep in mind the EU label doesn’t capture everything — dry-road handling, aquaplaning resistance, and wear rate aren’t part of the official rating, so it’s worth weighing alongside fuel efficiency and wet grip.
