Nearside Rear Tyre MINI Hatchback (F55) (09.2013 - ...)

Uneven wear on the left rear tire on your 2015 Mini Cooper S can be caused by several factors:
- Improper wheel alignment – ​​if the wheel alignment is out of alignment, the tire will wear faster.
- Suspension wear – damaged bushings or shock absorbers can affect load distribution.
- Tire pressure – if it is too low or too high, the tire will wear unevenly.
- Wheel balancing – an imbalance can cause uneven wear.
It is recommended to check the wheel alignment, suspension condition, and tire pressure.

Uneven wear on the nearside rear tire of your 2015 Mini Cooper S can be caused by several factors, but alignment issues and suspension problems are among the most common culprits.

Possible Causes

- Alignment Issues: Incorrect wheel alignment, particularly with the toe or camber settings, can cause one or more tires to wear unevenly. Too much positive camber (tilt outward at the top) can lead to outer-edge wear, while toe misalignment often causes inner or outer edge wear depending on the direction of the misalignment.
- Suspension Problems: Worn or failing suspension components—such as bushings, ball joints, wheel bearings, or shocks—can also lead to uneven tire wear. When these parts degrade, they may not keep the wheel properly aligned, causing the tire to wear more on one side.
- Tire Pressure: Under- or over-inflation can contribute to uneven wear patterns, but this usually affects both edges or the center of the tire rather than just one side.
- Lack of Tire Rotation: Not rotating your tires according to the manufacturer’s recommendations can exacerbate uneven wear, especially if there’s already a mild alignment or suspension issue.

What Others Have Experienced

Owners of similar vehicles, like the MINI Countryman R60, have reported excessive inner wear on rear tires, often pointing to alignment (toe) as the main cause rather than camber. However, suspension wear can also play a role, especially if the car is older or has higher mileage.

What You Can Do

1. Check Tire Pressure: Ensure all tires are inflated to the recommended PSI.
2. Inspect Suspension: Look for signs of worn bushings, ball joints, or shocks. If you notice any play or hear unusual noises, have a mechanic inspect these components.
3. Alignment Check: Have a professional check your wheel alignment. If the alignment is out of spec, correcting it should help prevent further uneven wear.
4. Tire Rotation: If you haven’t rotated your tires recently, do so according to your vehicle’s maintenance schedule.
