Selecting the right tyre is crucial for maintaining your vehicle’s original handling characteristics and safety features. Using the correct 235/45 R18 tyre ensures that your vehicle meets the manufacturer's engineering specifications.
When choosing your next set, consider these three critical factors:
- EV & Hybrid Compatibility: Many modern cars in this size are electrified. Look for the EV-Ready symbol to ensure the tyre can handle the instant torque and additional battery weight while maximising range.
