2018 BMW I3 Electric · LS68 OKJ

A clear pattern of tyre deterioration has emerged across the BMW i3's recent MOT history, with cracking and perishing flagged on both front and rear tyres through 2024 and 2025. The 2025 test proved particularly concerning, resulting in a Dangerous failure for a nearside front tyre exhibiting cord-exposing structural separation, alongside strong advice advisories for perished and cracked rubber on the offside front and offside rear. Five days earlier that same month, the vehicle had been failed for defective offside front side repeater lens and a partially non-functioning multiple-light source repeater, before passing on 11 February 2026 with only the recurring child seat inspection restrictions noted. The 2023 and 2022 tests remain the only blemish-free entries in the record, so the overall trend since then has been one of worsening component condition rather than a sustained record of clean roadworthiness. With 27,653 miles recorded across an eight-year life, this i3 has averaged roughly 3,457 miles annually, a notably low figure that places it well below typical usage for a vehicle of its age. The mileage progression between tests appears broadly consistent rather than erratic, with no evidence of clocked figures or sudden jumps, though the low annual accumulation does raise the usual considerations associated with light or irregular use. Stand-still periods can accelerate sidewall deterioration in tyres due to flat-spotting, ozone exposure and uneven pressure distribution, which aligns with the persistent perishing and cracking advisories on all four corners. For a prospective buyer, the tyres warrant immediate and thorough scrutiny. Inspect all four corners for sidewall cracking, particularly checking the tread shoulder and flex zone for hairline fissures that worsen with age regardless of remaining tread depth, and confirm manufacturing dates because rubber older than five years may perish despite appearing serviceable. On the road, listen for any rhythmic thumping or vibration that could indicate a developing bulge or separation, and verify steering remains straight without pulling. Given the structural cord failure that prompted a Dangerous classification, any tyre over six years old should be treated as a priority replacement regardless of its appearance. The front lighting cluster also deserves close attention before purchase. The failed offside front side repeater should be checked for correct operation with the indicators and hazard lights activated, and the lens examined for water ingress, cracking, or clouding that may be approaching a similar failure point on the nearside. On a test drive, confirm all exterior lighting functions correctly, including the daytime running signature characteristic of the i3, and ensure the indicators flash at the correct rate without hyper-flash warnings from any bulb-out detection system. Beyond these flagged items, the 2024 advisory regarding non-functional rear washers should be verified as resolved, and the i3's regenerative braking system should be evaluated for smooth deceleration without inconsistent pedal feel, since the hydraulic brake system on this model is comparatively small and any binding calipers or warped discs would be immediately apparent under light pedal pressure.
