Can you replace a 235 75 r15 with a 215 75 r15?

Yes, you can replace a 235/75 R15 tire with a 215/75 R15 tire, but there are some considerations. The 215 tire will be narrower, which may affect handling and traction, especially in adverse conditions. Additionally, the overall diameter and circumference will be slightly different, potentially affecting speedometer accuracy and vehicle stability. Always consult your vehicle's owner manual or a tire professional to ensure compatibility and safety.
