Just wondering how a 255/45/17 tire will fit most people always run the 40 instead of 45 is there a reason for that? Trying to do a squared setup

 

the tire will be taller (more sidewall) than a 40 series.
Most people run the 40 to maintain the stock rim/rubber ratio

I know what the 45 means I just don't know how it would look

 

255/40 is already slightly oversized diameter compared to stock. 255/45 will look strange and also have negative effects on gearing, speedo accuracy, etc.

 

Why does it matter how it would look? It would have negative effects on the car being much taller than stock. It would likely cause rubbing issues as well.

That is the answer I was looking for I didn't know it would have negative effects on the car don't see the need for your attitude but thanK you for the useful part of your reply

 

You asked how it would look not how would it affect the car. No attitude here just trying to get to the actual point.
