Help me go wider

Hello everyone, i need some help deciding. I'm going to list everything on my mind and see what you can come up with lol

I currently have this set up:

18 inch apex ARC-8's
F: 18 x 9 et 32 (et 42 with 10 mm spacer) w/ 255/35/18 Mich. PSS
R: 18 x 9.5 et 30 (et 35 with 5 mm spacer) w/ 275/35/18 Mich. PSS

My rear tires are almost done and i am trying to decide if i should:

a) just get new/used 275/35/18 mich pss tires. (my fronts are like 50%)
b) try to fit 285/35/18 tire in the back
c) buy a wider ARC-8 wheel 10" or 10.5" and throw atleast a 285/35 pss tire
d) move rear rims to front to get concave look, and buy wider rear rim/tires

Rubbing: right now i get mostly no rubbing. maybe on a really big dip or something with a full car will the rear rub slightly. its practically non existent front and rear. the tires rubbed when i first put them on but stopped after 5k miles

- rear fenders are rolled
- i have camber plates up front
- would like to continue to use my 255/35 tires up front til they wear out
- Camber: Front: -2.5 Rear: -1.8

i guess my question is: Can i move the 18x9.5 et35 rim to the front and throw the 255/35/18 tire on it? I can use the 5mm spacer i have to bring it to et 30 to clear the strut

If i do this, what rim size can i buy in the back that will allow me to fit the widest tire possible in the back? would need to be more than 275/35 to make it worth it. although concave up front is nice too

apex sells arc-8s with 18x10.5 et 27 and 18x10 with et25. can i fit a 295 or 285 tire on these

there is not alot of room in the rear or front as things are pretty maxed out already but all the offsets confuse me so please help!

9.5 up front should be no problem even with the 255 because of your camber specs.

Those offsets are too low for the rear though(with those tire sizes anyways, it can be done with some stretch). Apex ec7 comes in 18x10et33 or et43 either one would be a better choice to fit a wide tire.

285 would probably work on the wheels you have now but it will bulge out a little bit.
