I don't understand tires very well, so I'm hoping you guys can double check this.
I talked to the tire shop today about getting new winter tires put on. I have a 2009 Ford Focus SES with 215/45R17 Bridgestone Blizzak tires that are worn out. The tire shop wants to replace them over to 205/50R17 GTRadial Champiro tires, saying that they're a cheaper and better option for winter.
Is there anything wrong with doing this? I tried looking at some tire calculators online (this and this) and it seems like they would fit and don't deviate too much from what I have, but I'd rather double check before I go ahead with it.
From what I understand, is it correct in saying that the new tyres would be thinner but taller? Or am I reading this wrong?
