2021 Tesla Model 3 Long Range AWD Electric · AJ21 DWC

Recurring tyre wear issues and a recent dangerous failure for tread depth represent the primary mechanical concern for this vehicle. While the most recent test on 18 May 2026 resulted in a pass with no defects, this followed a failure just three days prior due to nearside and offside rear tyres falling below the legal 1.6mm limit. This failure, combined with a 2025 advisory regarding rear tyre wear, indicates a persistent pattern of tyre degradation that has escalated from a warning to a critical safety defect within a twelve-month period. The recorded mileage of 37,698 miles over approximately five years equates to an average annual usage of roughly 7,540 miles. This represents a relatively low-to-typical mileage profile for a vehicle of this age, suggesting the car has not been subjected to heavy long-distance motorway use. Mechanically, this level of usage generally implies less frequent wear on heavy drivetrain components, but the specific pattern of tyre wear noted in the MOT history suggests that the vehicle may be experiencing uneven contact patch issues despite the lower overall distance travelled. A prospective buyer should focus heavily on the wheel and tyre assembly, specifically investigating the cause of the repeated uneven or rapid wear on the rear tyres. The transition from an advisory in 2025 to a dangerous failure in 2026 suggests that the wear is not merely a result of mileage but could be linked to mechanical factors. During a test drive, pay close attention to any steering pull or vibrations at varying speeds, which could indicate alignment issues. Additionally, listen for any rhythmic thumping or humming noises from the rear of the vehicle, which may point to unevenly worn tread patterns or potential issues with wheel bearings or suspension geometry. Beyond the tyres, the recent failure for tread depth necessitates a thorough inspection of the suspension components that manage tyre contact. Check the condition of the rear suspension bushes and control arms for any signs of excessive play or damage. If the tyres are wearing specifically on the edges as noted in the 2025 and 2026 records, it is vital to verify that the camber and toe settings are within manufacturer specifications. Any irregular movement or knocking sounds when navigating uneven road surfaces or speed bumps should be treated as a potential sign of worn suspension linkages that may be contributing to the documented tyre issues.
