ratio

Power ÷ weight → tyres

Tyres matched to how hard your car works them.

Enter power and weight. ratio works out your power-to-weight, places it against 90 cars from a Kia Picanto to a Rimac Nevera, and tells you which kind of tyre to buy, which models to shortlist, and what ratings to look for.

Your tyre

Ultra-high performance summer

Sharp, sticky, and still sensible to live with.

Warm-tier power starts to overwhelm touring rubber, especially in the wet. UHP tyres add the braking and steering you need and still last.

About UHP summer tyres

For your car

  • Front-wheel drive

    Your front tyres do the steering, braking and driving, so they wear faster. Rotate front to rear every 10,000 km to keep wear even.

  • Wet grip matters most

    In a wet climate, rank tyres by wet braking first. On the EU tyre label the gap between wet grip classes A and E is up to 18 m when stopping from 80 km/h, several car lengths.

  • Buying only two?

    Put the new pair on the rear axle, even on a front-driver. Grippy rears keep the car stable when braking or cornering in the wet; worn rears are what cause spins.

Why a ratio

Power alone says little. Weight alone says less.

A 150 kW family SUV and a 150 kW roadster ask very different things of their tyres. Divide power by mass and you get a single number that tracks how hard the rubber is worked: how much force it transmits accelerating, how much heat it soaks up, and how quickly a cheap compound runs out of grip, especially in the wet.

ratio uses that number to set a floor for the tyre category, then adjusts for how you drive, where you live, your drivetrain and whether the car is electric. The result is a category, a shortlist, and the ratings to check on the sidewall. How it works
