Your fitment will be fine with the 275 rear on either wheel choice you've listed.

As for the 18x10.5 rear I'm assuming you mean the LMGT4? I've never seen a P45R in that size.

Very valid point i thought I seen somebody on here with. A 18x10.5 I will have to check. By running a +20 offset instead of a + 12 the barrel will be moved more toward the fender edge instead of sinking it in toward the strut am I right.

And can you put a 275 on a 10" wide rim?

Your thinking is backwards. The lower the offset, the further the barrel with be positioned from the hub. And yes a 275 is perfectly fine on 10" wheel.

Yes. Offset dictates the position of the wheel. Maybe closer to the fender. If so than you may want to go from a, say, 275 to 265 mm tire to keep the fender from cutting the tire.

GFY. That size is silly (opinion) and the OP should not use your set-up as a guide (fact). Oh, and 235s don't belong on the rear of a Z.

Maybe it's just. Manufacture thing.

If I get a different offset will it affect what size tire I run I don't want them to cone out past the fenders any input would be greatly appreciated thanks
You will still be good with a 255/40 and 275/40 combo

245/40 OR 255/35 and 275/35 OR 295/30 and you offset is sketchy on the rear, id add a spacer...at least a 20-25mm.

If you can return those wheels and buy more appropriate offsets for the car.. those are worse than stock.

I'd go with a 295 on the back and 255 front but offset is going to look horrible... and if you go with a drop you might get some rubbing...

255/40 and 275/40 would work fine , but you will most likely need a rear spacer. I would look at a 15mm spacer minimum.

I'd go for 245/275. Rears seem pretty high offset so I'd space them out as well.
