oooo... I don't know about a 245, that's pretty wide. And with a 245, I'd think you'd have to drop to a 35 aspec ratio in order to stop some SERIOUS rubbing. Maybe too wide for the wheel, but definately too tall for the wheel well.
For what it is worth, Falken Azenis run really narrow for a given size based on personal experience (dif car). The good thing about these tires is that they are inexpensive and have a reasonable treadlife. The only reservation I have about these tires is they do not quite offer the grip of summer max performance tires. But free is a big plus.
i.e. section width of 245 40 18= 9.6 (Falken)
section width of 245 40 18= 9.8 (Continental)
There are wider brands than continental
