2018 KIA Sportage 1.6L Petrol · C17 RBA

A chronic issue with rear tyre integrity dominates this Kia Sportage's MOT record, culminating in a dangerous failure at the most recent test on 24 September 2025 for an offside rear tyre with a structural tear alongside a front pair measured below the legal 1.6mm tread threshold. This is not a sudden development; the offside rear tyre has carried advisories for cracking or perishing at every test since September 2022, and both front tyres were already flagged as worn and cracked in 2022. A separate failure also occurred in September 2023 when the engine management indicator lamp was found to be inoperative or indicating a malfunction, though this did not recur on subsequent tests. Aside from these tyre and emissions-related items, the vehicle has passed cleanly with no brake, suspension, corrosion, or structural advisories recorded across the five-year testing window, and the 2021 test recorded no defects at all. Annual mileage averaging around 4,683 miles is well below the typical figure for an eight-year-old vehicle of this class, and the recorded odometer reading of 37,466 miles is consistent with relatively light use. There are no significant gaps between test dates, suggesting the car has remained in regular service rather than being laid up for extended periods, though the low accumulation does indicate that the vehicle has spent considerable time in light, short-journey use. Mechanically, such a profile tends to preserve the engine internals and major drivetrain components from wear, but it does expose consumables like tyres and brakes to the effects of standing, oxidation, and infrequent heavy use, which is directly reflected in the repeated tyre deterioration seen on this record. For a prospective buyer, the immediate priority is a full replacement set of all four tyres in a matching or higher specification, given that the dangerous failure applied to more than one tyre and the rear cracking has been a recurring observation for three consecutive years. On inspection, the sidewalls of all four tyres should be examined for visible cracking, bulges, or age-related perishing, and any tyres older than five years from their DOT stamp should be discounted regardless of tread depth. It would also be prudent to check the rear tyre brand, size, and load rating to confirm they meet the manufacturer's specification for the Sportage. A test drive should include firm braking from around 40 mph to assess for pedal judder or pulling, as the light usage profile can lead to brake disc corrosion and uneven pad transfer, particularly on a vehicle that may have experienced prolonged standing periods. Although no suspension, brake pipe, or subframe advisories appear in the MOT history, the buyer should still listen for knocking or clonking over uneven surfaces, which on a low-mileage Sportage can indicate seized suspension bushes or corroded anti-roll bar drop links that have not been exercised sufficiently to reveal themselves. Steering should be checked for any vagueness or uneven self-centring, and a visual inspection of the underbody, particularly around the rear axle and exhaust mounting points, is advisable given the persistent tyre cracking could suggest prolonged outdoor exposure. Finally, although the engine management light fault from 2023 did not reappear, an OBD diagnostic scan prior to purchase is sensible to confirm no stored or pending fault codes remain, as intermittent emissions-related issues can clear without addressing the underlying sensor or catalyst concern.
