It can, but you should confirm the exact approved size for your trim and wheel width. Check the tyre placard (door jamb), your handbook, or the size currently fitted, and match the required load index and speed rating. If your car has staggered wheels or an optional sports package, verify whether 245/40 R18 is specified for the front, rear, or both axles before ordering.
Use the manufacturer specification shown on the placard or in the handbook, then select that exact load index and speed rating, or higher if permitted. Do not choose a lower rating, as it can compromise safety and legality. If you are unsure, enter your vehicle details and compare options that match the required ratings, then order a full set to keep handling consistent.
Only if your vehicle is designed for a staggered set-up and the alternative size is an approved pairing. Mixing unapproved rolling diameters can affect ABS, traction control and speedometer accuracy. If a staggered fitment is specified, keep the same tyre model across each axle and replace in pairs to maintain balanced grip and predictable handling.
Summer tyres suit warmer months and deliver the sharpest response, which pairs well with the lower-profile 40 sidewall. Winter tyres are the safest option if you regularly face near-freezing temperatures, snow or slush, as they are designed to keep traction when summer compounds harden. All-season tyres are a practical year-round choice for many UK drivers who want dependable wet and cold performance without switching sets.
Pressure varies by vehicle weight, load and driving conditions, so use the manufacturer placard as the primary reference. Many cars running this size sit in a similar range, but the correct figure can differ between front and rear, and may change when the car is fully loaded. Check pressures when tyres are cold, recheck monthly, and update them after any temperature swings or long motorway journeys.
