A calculator estimates a car’s power-to-weight ratio, then suggests a tyre category, models to shortlist, and ratings to check.

Landing page captured for the 2026-09-30 issue.

For: Drivers choosing tyres for performance-oriented cars
Worth noticing: It cautions that the car’s door-jamb placard, not its estimate, sets the legal minimum load index and speed rating.

Field notes

The calculator lets users enter power and kerb weight or start from a car preset, then refine the result with driving, climate and tyre-priority choices. Its example output pairs a tyre category with grip, comfort and tread-life ratings, model suggestions and load-index guidance. A visible warning says estimates do not replace the legal minimum on the vehicle’s door-jamb placard.
