So I thought about going down to a 15” tire for the Comfortline which has a stock 205/55r/16. However, my tire specialist says on his wholesaler site there are no 15” rims available for this car. He recommended if I wanted to go with a narrower tire, he could get me a 16” rim with a tire size 195/70r/16. That's a variance difference of over 7% I believe. I heard it’s not safe if the variance is +/- 3%. Also I couldn’t t even find any major tire stores who stock tires in this size. Am I missing something here. I find it strange that you would not be able to get 15” wheels and tires for this car. Thanks.
