EV and modern vehicles
EV load, efficiency and cold-weather considerations for newer vehicles.
EV tires: specification, load and efficiency guide Source-reviewed EV tire guide covering approved size, load and speed ratings, pressure, EU labels, noise features and maintenance. EV tire speed rating: match the vehicle specification Source-reviewed EV tire speed-rating guide covering service descriptions, UN R30 symbols, load interaction and replacement checks. Tire pressure and fuel economy guide How tire pressure affects rolling resistance, fuel consumption, and CO₂ output: the 1 PSI / 0.5% MPG rule, what EU tyre label fuel efficiency grades mean, and what optimal pressure saves per year in fuel costs. Summer tires in cold weather: why summer tires lose grip below 7°C and what to do about it Guide to summer tire cold-weather performance: why summer tire compounds are formulated for maximum grip above approximately 7°C (the compound uses softer, stickier polymers that stiffen as temperature drops), what happens physically to the rubber below 7°C (compound transition toward a glassy state — the tire contact patch becomes less compliant and cannot conform to road texture asperities), how wet braking distance increases at low temperature (at 3°C a summer tire can require 20–30% more stopping distance than a winter tire in the same conditions), the "7°C rule" and when to apply it (daily ambient temperature below 7°C, not just night temperatures), what all-season tires actually offer at low temperatures (a genuine winter-rated 3PMSF all-season tire performs meaningfully better than a summer tire below 7°C but not as well as a dedicated winter tire), and the legal position (no general European law mandating winter tires except Austria, Finland, and partial requirements in some German states for specific conditions).
