2015 BMW I8 1.5L Hybrid electric · YE65 ODB

A recurring theme in this BMW i8’s MOT record is progressive tyre wear coupled with emerging rear‑disc wear, yet no outright failures have been recorded. The most recent test on 4 July 2026 returned a clean pass, following a series of advisories that began in 2018 with front‑tyre edge wear, expanded in 2022 to all four tyres and thin rear‑pad wear, and culminated in 2023 with both rear brake discs noted as worn, pitted or scored. The pattern shows wear‑related advisories persisting over several years while the vehicle has otherwise met the statutory requirements. At 54 507 mi the car averages just under 5 000 mi per annum, a mileage figure that is low for a 2015 model. Such light use can be consistent with occasional high‑speed or spirited driving, but the repeated tyre‑edge advisories suggest that the rubber has aged or been subjected to conditions that accelerate wear irrespective of distance. Tyre rubber degrades with time as well as use, so even with modest miles the tread may be approaching the legal limit, and the same logic applies to brake components that have shown thinning and disc scoring despite limited mileage. When inspecting the tyres, feel for a tread depth of at least 1.6 mm across the entire width and look for any cracking, sidewall bulges or uneven wear patterns that could indicate mis‑alignment or suspension issues. A test drive should include a brief high‑speed run to confirm that the vehicle remains stable and that there is no vibration or pulling, which would hint at tyre or wheel imbalance. Examine the brake pedal for a firm, consistent feel; any sponginess, pulsation, or grinding noises under moderate braking could confirm that the rear discs are indeed deteriorating and that the pads may soon require replacement. Given the history of brake‑disc advisories, listen for squealing or metallic chatter when applying the brakes, and note any vibration through the pedal or steering wheel that may indicate disc warping. Check the rear brake pads for a thin appearance through the wheel spokes and verify that the calipers move freely without binding. While the MOT record shows no faults in suspension or steering, a careful inspection of the front‑suspension bushes, coil springs and any audible clunks over bumps will help ensure that the low‑mileage usage has not masked wear in those areas. Addressing tyre and brake wear promptly will be essential to maintain the car’s roadworthiness.
