2015 Porsche 911 3.8L Petrol · JC65 GTS

A consistent pattern of rear-tyre edge wear advisories across three of the five recorded tests shapes the roadworthiness picture of this 2015 Porsche 911. In June 2026 the vehicle passed its MOT with advisory notes that both offside and nearside rear tyres were worn close to the legal limit and showing edge wear, mirroring the same dual advisories recorded in April 2025 and echoing the earlier observation from March 2022 that both rear tyres were approaching the limit. With clean passes and no advisories in 2023 and 2024, the recent recurrence of these notes in successive years is the primary mechanical signal from the test record. No structural, suspension, brake, exhaust, or corrosion advisories have been raised at any point, and there are no recorded failures, meaning the vehicle has held a continuous pass status throughout the documented period. The defining story, therefore, is one of otherwise tidy roadworthiness undermined by a recurring geometry or usage-related tyre wear issue at the rear axle. With five tests spanning 2022 to 2026 and 39,322 recorded miles against an eleven-year vehicle age, the annualised mileage of roughly 3,575 miles per year sits well below typical figures for a car of this type. The gaps between tests are reasonably regular at intervals of around twelve to fourteen months, suggesting the vehicle has remained in active use rather than laid up for long stretches. Lower annual mileage reduces wear on major drivetrain and friction components, but it can also mean longer standing periods between drives, which has implications for rubber sealing components, brake disc surface corrosion from infrequent use, and the condition of any underbody fasteners exposed to the elements. Given that the only recurring test note concerns tyre wear, the low-mileage profile is worth weighing against how the car has actually been driven in that mileage, particularly in terms of cornering loads and rear-axle alignment settings. For a prospective buyer, the rear-tyre edge wear pattern warrants close attention before purchase. Edge wear on both rear tyres simultaneously often points to consistent negative camber, excess toe-out, or inflation pressures that are too low for the load being carried, and on a 911 it is worth checking whether the car has been driven hard on track days or has been left sitting with under-inflated tyres. On a test drive, listen for any hum or drone from the rear that could indicate uneven carcass wear, and inspect the tread shoulders visually for feathering. Because rear brake disc corrosion is a known consequence of low-mileage use on performance cars, the brake pedal should be tested from a standing start for any judder or vibration through the pedal on the first firm application, which would suggest surface rust on the discs rather than a deeper warping issue. The handbrake should also be checked for full holding strength, as rear calipers on cars that see limited use can develop sticking slide pins. A physical inspection beneath the vehicle would be sensible given the age and the fact that the MOT record alone cannot reveal underbody condition. The rear suspension multi-links, inboard spring mounts, and anti-roll bar drop links should be examined for any oil seepage from the damper units or perished bushes, as these components are not always flagged at MOT level until deterioration is pronounced. Steering response should be assessed at low speed for any vagueness or knocking through the front end that could indicate worn front wishbone bushes or top mounts, even though no advisories have been raised in this area. Finally, because the recorded mileage is modest, confirmation of the last cambelt or PDK service interval is advisable, as Porsche maintenance schedules are time-based rather than purely mileage-based, and a service record separate to the MOT history will be essential to establish the mechanical condition beyond what the DVSA data can demonstrate.
