What should I verify before using this information?
Use TireFitLab values as a sizing reference, then verify the vehicle handbook, tire placard, rim compatibility, load rating, and physical clearance before fitting.
EV tyre guide What makes an EV tyre different: higher load from battery weight, torque-steer stress on tread, acoustic foam for road noise, and low rolling resistance for range. EV and hybrid tyre speed ratings explained Speed rating requirements for electric and hybrid vehicle tyres: why EVs often need higher speed-index tyres than equivalent petrol cars, what EV-rated tyres offer, instant torque and wear implications, and how to read tyre markings for BEV and PHEV applications. Tyre pressure and fuel economy guide How tyre 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 tyres in cold weather: why summer tyres lose grip below 7°C and what to do about it Guide to summer tyre cold-weather performance: why summer tyre 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 tyre 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 tyre can require 20–30% more stopping distance than a winter tyre 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 tyres actually offer at low temperatures (a genuine winter-rated 3PMSF all-season tyre performs meaningfully better than a summer tyre below 7°C but not as well as a dedicated winter tyre), and the legal position (no general European law mandating winter tyres except Austria, Finland, and partial requirements in some German states for specific conditions).

Use the budget and running-cost tools before a trip, especially if the current tyres are worn or the replacement size changes diameter.
