Wheel fitment questions

[south]

Hey so, im looking into getting a set of Chrome Rpf1’s 18x10.5 +15 in the rear and 18x9.5 +15 upfront. will these forsure clear the oem akebonos on my 370z? The car is lowered on H&R Springs, now i’m looking at tire setups I was thinking a 275/40/18 in the back and maybe a 245/40 upfront? Im not too sure on the front tire setup completely yet hence why im here. My questions are does anyone have this setup and can send me either their Ig or some pics of how it looks with this setup? Also will it rub in the rear or front? Anyone else have any other recommendations on tire setups that don’t rub but that have a decent amount of meat in the rear and the front looks good with the rear? I dont want it to look stupid.
