Did you know the 155/80/13 tire is the OEM size for my corolla?
The 175/70/13 tire is smaller so going back to the 155/80/13 tire will be larger and match my spedo, this was just the comperable and closest replacement for the car at costco and they just put them on you know. It was when my exgf owned it. thanks for your idea but maybe you did not understand I am actually going back to stock size.
