Default How wide can I go on the stock 19" rear?

Going to be getting new rear tires in the spring and just wanted to start shopping but need to know what is the biggest(widest) tire I can fit on the rear end with the stock 19's? Thanks - Sam

295 at a push, but 285's comfortably

285's on a stock 19x8 wheel, that is really going to be pushing it. The tire will be pulled in on the sidewalls with a tire that wide on a 8" rim.

Stock is a 245, I would think a 265 would be the max.

265/?/19
285/?/19

Trying to just do some comparing but have no clue what profile to go with. 265/40 and 285/40 don't work so what size would?

Thanks
