Suomi Tyres Routa — studded winter tire

The Suomi Tyres Routa is the Finnish all-round studded winter tire for commuting, gravel and city bikes. Its tread is shaped for shifting winter conditions — wet leaves and frost in late autumn, then packed snow and icy roads — without giving up rolling speed. Hundreds of Finnish steel studs bite into ice, a lightweight skinwall casing keeps the tire lively, and the reflective sidewall makes you easier to see.

Highlights

• Finnish steel studs — 212 (24 × 1.75), 248 (28 × 1.60) or 252 (28 × 2.0) studs for grip on ice
• Autumn-to-winter tread — traction from first frost to deep winter, low rolling resistance
• Lightweight skinwall casing — keeps the tire quick and supple
• Puncture protection — extra durable casing and a non-toxic winter rubber compound
• Reflective sidewalls — on every Routa
• Tubeless-ready (TLR) — 28" sizes run with a tube or tubeless

Fit

Check the size printed on your current tire's sidewall: 47-507 fits 24" wheels (kids' and compact bikes), 42-622 is a common city and trekking e-bike size (700 × 42C), 50-622 fits wider 28"/29" rims (700 × 50C). New studs need a gentle break-in: ride the first 40–50 km on tarmac without hard braking or cornering so the studs seat properly.
