For the reference – if someone finds it useful and may want to use it in the future
Dear Motability Scheme Team,
I am writing to formally dispute your decision to impose a Fair Usage Policy limit in respect of tyre replacements on my vehicle, and the resulting assertion that I am now responsible for future tyre costs.
The decision appears to have been reached without adequate consideration of the known wear characteristics of the vehicle configuration in question, nor of well-documented performance issues associated with the specific tyre fitment supplied.
1. Vehicle and usage context
The vehicle is a Škoda Enyaq 85x SportLine, fitted with 21-inch wheels and Bridgestone Turanza Eco tyres, and has covered approximately 48,000 miles. This is a high-mileage usage profile within the normal scope of a Motability lease.It is widely recognised within both OEM documentation and independent analysis that large battery electric SUVs of this type impose significantly higher tyre loadings due to:
High kerb weight (c. 2.2 tonnes depending on specification)
Instant torque delivery to both axles (AWD configuration)
Increased tyre deformation under acceleration and regeneration loads
Larger wheel diameters with reduced sidewall compliance (21” configuration)
These factors materially increase wear rates compared with equivalent internal combustion vehicles.2. Known Enyaq tyre wear behaviour
Independent owner reports and technical discussions relating to the Enyaq platform indicate a recurring pattern of accelerated tyre wear, particularly on 20” and 21” wheel configurations, including:Inner and outer shoulder wear linked to alignment sensitivity on the MEB platform
Reduced tyre life in high-mileage usage (often reported in the 15,000–25,000 mile range per set depending on driving conditions)
Higher-than-expected wear rates on OEM Bridgestone fitments compared with premium alternatives
This is consistent with broader EV fleet data showing that heavy electric SUVs routinely experience accelerated tyre consumption relative to ICE equivalents, particularly when fitted with large-diameter wheels.3. Bridgestone Turanza Eco (21”) – documented concerns
The Bridgestone Turanza Eco (OEM 21” fitment) has been widely discussed in owner forums and independent tyre review platforms, with recurring observations including:Moderate treadwear ratings relative to premium touring EV alternatives
Noticeably reduced tread life under high-torque EV applications
Earlier-than-expected replacement cycles on heavy EV SUVs
Performance trade-offs linked to efficiency-oriented compound design
While performance characteristics vary by driving style and conditions, there is a consistent pattern of shorter-than-average service life when used on heavy AWD EV platforms such as the Enyaq 85x.4. Deficiencies in your assessment
Your correspondence does not provide:Any defined numerical threshold for “Fair Usage” in measurable terms (miles, tread depth, or cost ceiling)
Any differentiation between standard passenger car usage and heavy EV SUV usage
Any consideration of OEM tyre specification and its impact on wear rate
Any evidential basis demonstrating abnormal or excessive usage on my part
In the absence of such information, the application of the policy appears arbitrary and not properly grounded in vehicle-specific engineering reality.5. Position
On the basis of the above, I do not accept that tyre wear in this instance constitutes excessive or non-standard usage. The wear profile is entirely consistent with:Vehicle mass and drivetrain characteristics
Wheel and tyre specification selected at factory level
Established real-world EV SUV wear behaviour
Accordingly, I do not accept liability for future tyre replacements arising from normal operational wear of the vehicle as supplied.6. Required resolution
I request the following without delay:Full written definition of the Fair Usage Policy threshold applied, including methodology and measurable limits
Confirmation of the baseline tyre life assumptions used for the Enyaq 85x or equivalent EV SUV
Complete record of tyre replacements on my vehicle, including mileage and justification
Written confirmation of how EV-specific wear characteristics and 21” OEM tyre fitment have been factored into your assessment
Suspension of any charge liability pending formal review of this determination
Until such time as this information is provided and properly assessed, I do not accept the validity of the decision as communicated.Yours faithfully,
Sent from a mobile device.
