2021 Toyota C-HR 1.8L Hybrid electric (clean) · RF21 XUE

The 2021 Toyota C-HR presents a mixed roadworthiness picture marked by intermittent tyre deterioration alongside a generally stable overall test history. The most recent MOT on 2026-03-30 returned passed status but carried a critical advisory noting the nearside front tyres were worn close to the legal limit at approximately 2mm of sidewall wear, while an earlier failure on 2025-04-08 revealed headlamp aiming issues that required correction before that test could be fully satisfactory. Two prior tests showed progress with rear tyre concerns being addressed in April 2024 and April 2025, though each of those occasions also produced additional advisories related to tyre damage or cracking. This pattern of recurrent tyre-related warnings—spanning three separate MOT cycles across nearly two years—suggests the tyres are experiencing accelerated wear despite the low odometer reading of 27,426 miles, which raises questions about whether the vehicle has been driven frequently enough to justify such rapid degradation or if something else is contributing to premature tyre consumption. The mileage figure of 27,426 miles on a five-year-old vehicle translates to roughly 5,486 miles per annum, a rate that appears modest compared to typical usage profiles for this model segment. While this pace does not immediately suggest excessive wear on suspension bushings, brake pads, or clutch components, the distribution of tyre advisories across different wheels indicates that the tyres themselves are the primary factor requiring scrutiny regardless of total mileage. The gap between the April 2025 and March 2026 MOTs spans just over a year, which is within normal intervals for scheduled inspections, yet the presence of fresh tyre warnings at the end of the current registration period implies that the tyre system has not kept pace with whatever level of use occurred since the last test. Low mileage combined with persistent tyre advisories can sometimes point toward irregular driving patterns—such as short trips that don't allow the tyres to reach optimal tread depth, or periods where the vehicle sits idle—which may manifest as uneven wear bands or cupping that isn't captured in the numerical mileage readout alone. Based on the recorded advisories, particular attention should be given to the front nearside tyres shown at 2mm wear on the latest MOT, as this approaches the legal minimum and could indicate gradual deformation or uneven contact patch loss. During a test drive, listen for any knocking or chattering over bumps, particularly when travelling at speed, as this can signal worn suspension linkages or deteriorating coil spring behaviour. The front tyres should be inspected visually for any bulging edges, cuts, or uneven wear across the contact patch, and the steering should be checked for play in the suspension arms that might contribute to uneven tyre wear. Additionally, verify that the headlights are properly aligned and aimed, as the 2025-04-08 failure highlighted this as a source of non-compliance even when the tyres were functioning adequately. A thorough check of the brake disc condition and rotor surface should also be performed, as brake pad thickness measurements and pad wear indicators will reveal whether the braking system has remained within safe operating parameters throughout the vehicle's service life. The rear tyres have a documented history of slight damage or cracking reported in both April 2024 and April 2025, which suggests that this area of the vehicle has experienced mechanical stress or environmental exposure that may require deeper investigation. When assessing the rear tyres, pay particular attention to the sidewalls for signs of dry rot, cracks, or delamination that could compromise structural integrity, especially if the vehicle has spent significant time outdoors or in damp conditions. The subframe and mounting points around the rear tyres should be examined for any signs of rust penetration or fastener corrosion that could develop over the years, particularly given the low mileage which might mask otherwise obvious structural decay. If the tyre wear patterns on the rear axle appear asymmetric, this could indicate differential bearing loads or potential issues with the rear suspension geometry that may not be apparent from visual inspection alone. Finally, confirm that all fluid levels—including transmission fluid, coolant, and brake fluid—are within specification and free of contamination, as accumulated contaminants in older fluids can accelerate internal component wear even when external visible problems remain hidden.
