Will 40mm offset work?....

i would definitely not put 245-width tires on a 10" wide rim, especially ones with that short of a sidewall
i'm going to assume you're talking about an f-body here....if so, i really don't think 20" wheels is going to look good, perform good, or last long (if it's driven on the street much)
if you absolutely have to go big, my cut-off limit would be 19's.....but preferably 18's so that they don't look out of place
but if you're absolutely dead-set on 20's, stick with 275-width or wider on all 4's

And being that the car is lowered the wheel and tire will tend to tuck in more at the top.


Given the fact that your car is lowered you should be golden just like I was. You have to understand the more the car is lowered the more the top of the tire moves in. Following the arc of the suspension travel. If it was a stock height car I would say no go with that offset.
Your tire will be flush, but you are at the limit....still should be behind the fender. But everyone's expectation is different.
Personally I like a 285 on a 10" wheel over a 275....more side wall to protect the rim.
But if I had to recommend one over the other. Go with the one that's shorter in overall height. So go with the 275/30's.......make sure the tire is no taller than 26" maybe 26.1" max
GL and post some pics when you get them mounted.
