I am pretty confident the fronts will fit.... but.....
#1 the calipers might still hit wheel depending on wheel design, I tried a 17x9 with et 30 and even with 20mm spacer fronts still hit caliper
#2 I run 18x8.5 et45 with 20mm spacer front (for 25et) and they poke just the right amount in my opinion
#3 I do run 215/40/18 front And 225/40/18 rear.
I think rears would fit just don't mount wider than 245 on the rear, do a mild stretch 235 - 235...I didn't feel the need for a tire wider than 225 on back, I just roll the Merc!!!! The deal is its not hard to fit wide aggresive wheels, its hard to fit wide fat tires,,,,,,,
