I bought these tires to replace the Kumho that came on the vehicle. Immediately perceived a change in both the acoustic effect and the degree of softness exhibited by the suspension. I used the measurement 195 and 55 for 16. I looked for it and had recently purchased some BF Goodrich summer tires, which everyone seemed to like according to the reviews, but I was quite unsatisfied with the sound of stones and sand on the bottom of the tires. I made the decision to switch back to Sailun, and after that, I did not experience any discomfort. I strongly suggest it to everyone! besides that, I went up a size to a 205/50 16 and it fits perfectly. The Kia Rio is fine, and there is nothing wrong with it.
