Can 235-45-18 tires replace of 235-50-18 tires?

Yes, 235/45-18 tires can replace 235/50-18 tires, but there are important considerations. The 235/45 tire has a shorter sidewall height compared to the 235/50, which can affect ride comfort, handling, and speedometer accuracy. Additionally, the overall diameter of the two tires differs, so it's essential to ensure that the new tire size is compatible with your vehicle's specifications and that it won't affect clearance or performance. Always consult your vehicle's manual or a tire professional before making a change.
