245 is the tyre width in millimetres, 60 is the sidewall height as a percentage of the width, and R18 means it fits an 18 inch wheel. This combination is commonly used on SUVs because it balances footprint, ride comfort and load capacity. Always match the size exactly to what your vehicle specifies.
This size is often fitted to mid to large SUVs and 4x4s, including selected trims of the Kia Sorento, Hyundai Santa Fe and Toyota Highlander. Fitment can vary by model year, drivetrain and wheel option, so check the tyre label on the door pillar, the handbook, or your current tyre sidewall before ordering. If your vehicle has staggered sizes, match the front and rear specifications.
Use the minimum load index and speed rating shown on your vehicle placard or in the handbook, and do not go below it. Many options in this size are offered with higher load ratings or XL (extra load), which can be important for SUVs, full passenger loads and towing. When browsing, filter by your required rating so the tyres you choose are compliant and suitable.
These sizes have different overall diameters, which can affect speedometer readings, ground clearance and tyre-to-arch clearance. Only change size if it is an approved alternative listed by the vehicle manufacturer or confirmed by a tyre professional. If in doubt, stick to the size on the vehicle placard and inform your insurer if any non-standard fitment is used.
Summer tyres suit warmer months and prioritise dry and wet road performance, while all-season tyres are a strong year-round option for mixed UK conditions and moderate winter weather. For frequent cold-weather driving, winter tyres marked 3PMSF offer improved grip in snow and on cold surfaces. Whichever you choose, fit the same type across an axle, and ideally all four, to keep handling consistent.
