Default 275-40-18 to big for stock rears

I want to go a little bit larger on my factory wheels At least on the rear just wondering if anyone had tried to put a 275-40-18 on the rear and if so how was the clearance.

Thanks

another member has fitted 275's (35 or 40 aspect ratio, i forgot) on oem 18x8.5's, and supposedly it fits.

having said that, it depends on what your ride height is, though i can't imagine it not being able to fit under stock fenders. your rear fender liners might not like it, however...

^ i thought staggered oem 18's were 18 x 8.5?

(at least that's what the OP implied, or maybe i shouldn't have made that assumption?...)

That would be me.

I just had them installed and although I must say they are really beefy, I think they are just a tad bit over my taste for tires on an 18'' wheel. I'm contemplating installing spacers to widen the stance a little but I'll have to do some more research on that. I may be able to snap a picture for reference for you. My advice would be go with maybe a 265/35, it should have enough width to make it noticeable yet not too over the top. Oh and btw, I'm dropped on coils with no issues at all with the tires.

I am only asking if anyone has tried it because the tires i at Nitto Neogen they make 225-40-18 but they dont make 255-40-18 but they make a 275-40-18
If you could send me some photos that would be sweet

according to the nitto neogen product page, for 40-series 18" tires sizes it goes from 215 to 245 incrementally and then a considerable jump to 275.
