The MG5 is front-wheel drive with significant torque, leading to faster-than-expected front tyre wear. This is worse in Eco mode which can cause wheel spin on damp surfaces.

Est. Repair Cost: £100–£200 per tyre
Warning Signs:

Front tyres wearing faster than rears, Uneven tread wear pattern, Reduced grip in wet conditions

What to Inspect:
  • Compare front and rear tyre tread depths
  • Check the tyre pressures are correct
