2023 MINI Countryman 1.5L Petrol · YE73 OLX

A recent MOT failure centred on tyre safety – an off‑side rear tyre was found with a cut deep enough to breach the ply, and mismatched tyre sizes were recorded on both the near‑side front and rear axles. The subsequent test three days later passed with no recorded defects, indicating that the tyres were replaced and the size discrepancy corrected before the next inspection, but the episode flags tyre condition as the primary mechanical concern for this vehicle. With 30,970 mi recorded on a three‑year‑old 2023 Mini Countryman, the average annual accumulation is roughly 10,300 mi, which sits comfortably within normal private‑use expectations. No prolonged gaps between MOTs are evident in the supplied data, suggesting the vehicle has been kept on the road consistently rather than stored for extended periods. This mileage level places the car into the early‑to‑mid‑service‑interval bracket, where consumables such as brake pads, suspension bushings and tyre tread are approaching the point where wear should be inspected but are not yet likely to be at the end of their service life. When evaluating the car, give particular attention to the current tyre set: verify that all four tyres are of the same specification, size and tread depth, and inspect the sidewalls for any cuts, bulges or repaired patches. Check that the wheels are free of curb damage and that the rims are not bent, as mismatched tyres can have placed uneven loads on the suspension. During a test drive, feel for any vibration or pull to one side at higher speeds, which could indicate residual alignment issues or wheel imbalance stemming from the earlier tyre mix‑up. Beyond the tyres, conduct a standard road‑worthiness check of the braking system – ensure the pedal feels firm and that there is no judder when applying moderate pressure, and listen for any abnormal squeal that could point to worn pads or discs. Inspect the suspension components, especially the front and rear lower arms and bushings, for any looseness or excessive play, as uneven tyre wear can sometimes mask underlying suspension wear. Confirm that the wheel‑speed sensors and ABS warning light are inactive, and that the vehicle’s electronic stability systems engage without fault codes. These focused checks will confirm whether the car’s mechanical condition aligns with the clean MOT record following the tyre remediation.
