Currently I have 235/40/18 on my Mille Miglias... now my question is this. What is the largest size i can put without the tires rubbing. I have seen 245/40/18 and I have also heard 245/45/18. If I can, I would like to go with 245/45. I am ordering the tires today, sooo any help would be great.... Thanks

 

The correct ratio in proportion to the stock wheels would be a 235/40. Anything else would be pushing it! Maybe a 245/40. But nothing larger than a 40 series tire! Especially if the car is lowered or you plan to lower it.
