285 is the tyre width in millimetres, 45 is the sidewall height as a percentage of the width, R means radial construction, and 19 is the wheel diameter in inches. Matching these figures exactly helps ensure correct fitment, handling and speedometer accuracy.
Check the vehicle placard (door shut), handbook, or your current tyre sidewall and match the required load index and speed rating. This size is often specified with higher load ratings for heavier SUVs, so do not downrate to a lower load index, especially if you carry passengers, tow, or drive at motorway speeds.
If your vehicle specifies Extra Load (XL) or reinforced tyres, choose an XL version to meet the required load capacity and keep the handling stable under weight. If XL is not required, you can still use it as long as the load and speed ratings meet or exceed the manufacturer specification, and you follow the recommended tyre pressures.
All-season tyres can be a strong choice when you want one set year-round, particularly for SUVs that see mixed weather and cooler temperatures. Look for the 3PMSF symbol if you want improved traction in winter conditions, then compare wet grip and noise ratings to balance safety and refinement.
Read the size printed on the sidewall of your current tyres and compare it with the vehicle placard or handbook, as some models have different front and rear sizes. Avoid switching to nearby sizes unless your manufacturer approves it, because changes in rolling radius can affect clearance, speedometer readings and AWD systems.
