Best replacement tire size for stock rims?

[Uber_Otter]

Im going back to the 185/60 15s, I run stock steelies. I had replaced all four with 195/65 15s and it was bad. Mainly the 65 part, way too much sidewall lots of flex. The increased overall diameter\weight means your just pissing torque away too. It was noticable. The guy at discount tire company suggested them, i said okay, now I know better. Wider is ok, taller's not. I'll go wider when I get some lighter rims to make up the difference in unsprung wieght.
I order tires from tiresonline.com and install them myself with a harbor frieght tire changer and bubble balancer. First one was a beating, now it takes about 10 min a tire.

I can't believe he sold you 195/65/15's for a Yaris. More proof to never let these morons make decisions for you. Tire shops are known for selling stuff that just needs to be unloaded from inventory. Always do your own research and decide on a tire/size before going into a store.

However, you don't need to go back to 185's. 195's are very good, just keep the aspect ratio to 60 or below.
