Is it ok to put a 195 70 r14 on a car that has 195 75 r14?

Yes, you can generally replace a tire with a size of 195/75 R14 with a 195/70 R14, as the width remains the same. However, the lower aspect ratio of the 70 series tire means it will have a smaller overall diameter, which can affect your speedometer accuracy and handling. It's important to ensure that the new tires do not interfere with your vehicle's suspension or wheel wells. Always consult your vehicle's manual or a tire professional for specific recommendations.
