It breaks down into a 245 mm tyre width, a 30% profile (around a 74 mm sidewall), radial construction (R), and a 19-inch rim diameter. Because the profile is so low, small changes from similar sizes like 245/35 R19 can noticeably affect ride height and speedometer accuracy. Always match the size listed on your vehicle placard or in the handbook.
Most manufacturers list this size as suitable for roughly 8.0 to 9.5 inch wide 19-inch wheels, with 8.5 inches commonly used as the measuring rim. If the wheel is too narrow or too wide, you can see uneven wear and less predictable handling. Check the wheel width stamping and confirm the tyre maker’s approved range for the exact pattern you choose.
Many 245/30 R19 options are XL (Extra Load) because the size is often fitted to higher-performance setups that require more load capacity. You should match or exceed the load index and any XL marking specified by the vehicle manufacturer. If your car calls for XL, fitting a standard load version can compromise stability and durability.
Yes, but only if the front and rear sizes match the manufacturer’s approved combination for your car and wheels. The rolling circumference must stay within safe limits to avoid upsetting ABS, traction control and speedometer readings. If you are unsure, replace tyres in axle pairs and check the handbook or the original tyre label before ordering.
Summer tyres are the most widely available in this size, while winter and all-season options can be more limited due to the very low profile and wide footprint. For mild UK winters, all-season can be a practical compromise if you want one set year-round, but it will not match a dedicated winter tyre on snow and ice. If you drive in colder regions or regularly see near-freezing temperatures, a second seasonal set is often the best solution.
