help needed!

looking for a set of tires for my Camaro.
the fronts are in need of replacement .
they are 165R15s
I cant find my conversion chart for the updated tire size.

I just go to a tire shop and ask for 165r15's. I usually have no problem getting them. Then when they ask what car it's going on, they either question why or their eyes light up.

yeah i tried that and they refused me service due to the speed rating on the tire they had .
I knew the conversion number but lost it.
