Max tire size on 308 . .. . again . . .weird size sorry

Another tire size question:

My track car runs 275-45-16 on rear and 245-45-16 on front.

That rear is a really messed up size for anything but Hoosiers . . . if I'm wrong on this please let me know what else is available in that size.

Based on some info in another thread, these tires might work on my 308 since I have the QA1's. I've attached a link that shows the size of the Hoosier . .. anyone think these tires have a chance of fitting under the rear? Be great if something else was available besides the Hoosier . . . at $237/pc they don't seem too pricey for all out sticky . .. but be nice if there were some other options for the street.

Also, what about that size on the front? . .. which is what I have on the rear right now.

What does the term "over tire-ing a car" mean?

Thanks,

285-30-18 are a little shorter than 275-45-16 in the Hoosier . . . is that the 285-18 you're referring to or different aspect ratio?

You think no go on 245-45-16 on the front . . . aspect ratio has a lot to do with this doesn't it when comparing sizes (think that's what it's called)?

You think you've got your offsets optimized with the fender lip rubbing? Maybe that's what you're referring to "wheels set-up at the moment" What's the scenario when you rub? Give me your complete tire size so I can see how big they are.

Thanks,

Sean
