Check the tyre size printed on your current sidewall and compare it with the tyre information sticker (often inside the driver door) or your handbook. If both confirm 245/55 R19, you are in the right place. Also check whether your car uses the same size front and rear or a staggered setup, as some SUV trims do.
Only change from 245/55 R19 if the alternative size is approved for your exact model and wheel, as different sizes can alter rolling radius, speedometer reading and clearance. Even small changes may affect handling and can cause rubbing on full lock or under load. If you are unsure, stick to 245/55 R19 and match the full specification on your existing tyres.
245 is the tyre width in millimetres, and 55 is the profile, meaning the sidewall height is 55% of 245 (about 135 mm). R indicates radial construction, and 19 is the wheel diameter in inches. When buying 245/55 R19, you also need to match the load index and speed rating shown after the size, as these are part of the required specification.
The correct choice depends on your vehicle, but many 245/55 R19 tyres are available with SUV-suitable ratings, often around 103 to 109 load index and H or V speed ratings. You should match the ratings on the door placard or your current tyres, or choose a higher rating if permitted. Avoid fitting a lower load index or speed rating than specified, especially on heavier SUVs or when towing.
All-season tyres in 245/55 R19 can suit UK conditions if you want one set for cold mornings, heavy rain and occasional snow without swapping seasonally. Look for the 3PMSF symbol if you want stronger winter performance than a standard M+S marking. If you prioritise warm-weather grip and sharper steering response, a dedicated summer tyre in 245/55 R19 may be the better match, with winter tyres reserved for colder months.
