Confirm the size on the tyre sidewall and cross-check it against the driver door placard or the handbook, as some models use different sizes front and rear. If your car has a staggered set-up, keep the same size on the same axle and replace tyres in pairs for consistent handling. If the placard lists multiple approved sizes, stick to one of those to avoid clearance and speedometer issues.
In most cases it is not a like-for-like swap, because the overall rolling diameter drops and that can affect speedometer accuracy, ground clearance, ride comfort, and how ABS and traction control behave. Only make that change if your vehicle manufacturer lists it as an approved alternative size. If you are unsure, match the size already fitted or check the placard before ordering.
Use the vehicle placard to choose the exact load index and speed rating, then match or exceed them when selecting tyres. This size is commonly specified with higher performance ratings, so filtering by the correct rating helps you avoid options that are unsuitable or not road-legal for your car. If your placard requires XL (reinforced), make sure the tyre is marked XL as well.
Yes, many tyres in this size are available as XL and some are offered as runflat, depending on the brand and model. Choose runflat only if your vehicle is designed for it and you want the ability to drive on after a puncture, as ride comfort can be firmer. Do not mix runflat and non-runflat across the same axle, and follow the placard if it specifies XL.
Summer tyres suit UK driving when temperatures are typically above 7C and you want the sharpest dry and wet performance. Winter tyres with the 3PMSF symbol are the better option for regular cold weather, slush, or snow, which can be especially noticeable with wide, low-profile tyres. All-season tyres balance year-round convenience with improved cold-weather grip compared with summer tyres, making them a practical choice if you prefer one set for mixed conditions.
