First confirm the rim diameter is 24 inches, then check your current sidewall markings and your vehicle placard to make sure the width and profile match what is approved. 245/30 R24 typically suits a rim width around 8.0 to 9.5 inches, but arch clearance and suspension setup can still limit fitment on lowered or modified vehicles. If you are changing wheel width or offset, measure inner and outer clearance before ordering.
Match the exact load index and speed rating specified for your vehicle, not just the tyre size. Many vehicles running 24-inch upgrades are heavier SUVs, so an XL (Extra Load) version is commonly required, but you should follow the manufacturer specification on the door jamb or handbook. Choosing a lower rating than specified can affect safety, insurance, and MOT outcomes.
XL options are often available and can be a better match for heavier vehicles or higher loads, while run-flat availability in this size is usually limited compared with more common 18 to 21-inch fitments. Use the filters to narrow by XL, brand, and any run-flat markings, then compare the EU label for wet grip and noise to pick the best option for your driving.
A 30 profile has very little sidewall, so you can expect a firmer ride and less cushioning over potholes and sharp edges. Keeping pressures correct is crucial, as under-inflation can increase the chance of sidewall damage and alloy scuffs. If you drive frequently on rough urban roads, consider tyres with reinforced construction or a rim-protector design where offered in this size.
The overall diameter drops by roughly 3 percent when moving to 245/30 R24, which can change speedometer readings, ground clearance, gearing feel, and how close the tyre sits to the arch. It may also influence how ABS and stability systems interpret wheel speed. Before switching, check the vehicle manufacturer guidance and aim to keep the rolling radius close to the original specification.
