the stock size is 215/45 ? the plus one is 225/40. The 235 is stretching it on a 7.5 imho. I bought wider wheels and put 225/40 but also worried about the rear fender as my car gets a little lower with different springs. I am going to consider 235 in front for the 1/4 mile though when i replace the fronts again. Also to the op, the narrower shorter tire often weighs less, you have some light wheels already and maybe you can gain traction with a softer tire without getting big. I think its rotational mass theory or something they say is important to go faster.
But maybe you are going for the wheel gap. Probably gotta roll the rears then
