Only if your vehicle handbook or door pillar sticker lists 265/40 R19, along with the correct load index and speed rating. This size is often used on the rear axle, so confirm the front size before ordering a full set. If you are moving from a different width, profile or wheel size, check manufacturer approval before fitting.
Start with the figures specified for your exact model and axle, then match them when you buy. 265/40 R19 tyres are commonly offered with higher ratings such as 102Y and often in XL, but the correct choice depends on your car. The load index must meet or exceed the minimum requirement, and the speed rating must be the same or higher than the vehicle specification.
Choose runflat if your car is set up for it and you want to drive on after a puncture for a limited distance. Runflats rely on compatible wheels and a working tyre pressure monitoring system, and they can ride firmer than non-runflats. If you switch to standard tyres, make sure you have an alternative puncture solution and that the change suits your vehicle requirements.
You can, but replacing in pairs on the same axle is usually the better option for consistent grip and braking. If you replace a single 265/40 R19 tyre, match the same brand and pattern where possible and keep tread depth close to the tyre on the other side. For AWD vehicles, check the manufacturer guidance on allowable tread depth differences before fitting just one.
Yes, you can buy 265/40 R19 in summer, all-season and winter options. Summer tyres suit warmer conditions and performance driving, all-season tyres are a popular choice for year-round UK use, and winter tyres marked with the 3PMSF symbol give the strongest traction in cold weather and snow. For best results, fit the same seasonal type across all four wheels.
