Product description & features
The Sonix WINTERXPRO 999 is a winter tyre designed for everyday passenger cars needing dependable control when temperatures drop. It’s built to perform in typical UK winter conditions such as cold, wet roads, slush and occasional snowfall, helping you maintain confidence on commutes and longer motorway journeys when summer tyres can feel less predictable.
These tyres use a winter-focused tread pattern with wide grooves to move water and slush away from the contact area, supporting strong wet braking and reducing the likelihood of aquaplaning. Dense 3D-style siping creates extra biting edges that interlock with the road surface, improving traction during pull-away and aiding stability on compacted snow. A cold-weather rubber compound is designed to stay more flexible in low temperatures, so grip remains consistent as the weather changes.
On the road, an optimised footprint helps spread load more evenly for steadier cornering and more uniform wear over the season. The casing is tuned for a controlled, comfortable drive, with tread blocks arranged to limit unnecessary vibration and road noise for daily use. Sonix WINTERXPRO 999 tyres are offered in a broad range of common car sizes to suit many hatchbacks, saloons and estates.
You can buy the Sonix WINTERXPRO 999 online in all available sizes on Tyres.co.uk, then choose fitting at a nearby garage of your choice or opt for delivery to suit your plans.
