The base 18's are 18 x 8 not 8.5

255 is probably the limit.

255 would be the largest I would recommend as well.

I would say 245 or maybe 255.

I would say 245's.

255 buldges a bit more so more edge protection, but either or will work.

Why not 265/45???

Its a oddball tire size, pricier and budlges a tad more. Your not utilizing that much tire because your width is not wide enough to use it all on a 18x8.
