It will fit only if 255/50 R19 is listed as an approved size on your door jamb sticker, handbook, or current tyre sidewall. The size must match the wheel diameter (19 inch) and also meet the correct load index and speed rating for your model. If your vehicle lists multiple sizes, choose the one that matches your wheel set and any factory options such as staggered fitments. Once confirmed, you can shop confidently knowing the tyres will be compatible.
Select a load index and speed rating that matches, or exceeds, the vehicle manufacturer requirement shown on the placard. This size is often used on heavier SUVs, so you may see higher load indices (commonly around 107) and speed ratings such as V or W, but your exact requirement can differ by model and trim. Keeping the correct rating maintains the vehicle’s intended handling and braking performance. Use the filters to narrow results to the exact rating you need.
Choose XL only if your vehicle specifies an extra load tyre or a load index that typically requires XL construction. Many SUVs that use this size can require XL due to higher axle weights, especially with passengers, luggage, or towing. If your current tyres are marked XL and the placard agrees, replacing with XL like-for-like is the safest choice. Matching the required construction ensures the tyre can carry the intended load.
Mixing run-flat and non run-flat tyres is not recommended, particularly on the same axle, because sidewall stiffness and response can differ. If your vehicle was factory-equipped with run-flats and you do not carry a spare, staying with run-flats helps preserve the intended mobility strategy after a puncture. If you decide to switch type, do it as a full set and check your vehicle guidance first. Keeping the same type across the car maintains consistent handling characteristics.
Summer tyres suit most UK conditions and typically give the best steering feel and braking in milder temperatures. All-season tyres are a strong choice for year-round use if you want one set that copes better when temperatures drop, especially when marked with the 3PMSF symbol. Winter tyres make sense if you regularly drive in sustained cold conditions or face snow and ice, as their compound and tread are optimised for those conditions. Picking the right season type helps your SUV perform predictably throughout the year.
