Cool Maximum tire widths for stock 18" rims

I have an '07 Wrangler Unlimited with stock 18" rims. The stock tires are 255 70R 18s, mounted on 18" rims that measure 7.5" in width. I wanted to get wider tires, so how wide can I go with the stock rims - 275, 285? Also, I wanted to get wheel spacers (1" - 1.5"). Do you need any special modifications to prevent damage to wheel bearings or axles? Please let me know. Thanks.

I don't know crap when it comes to metric tire sizes and stuff like that...

But I have 33X15X12.5 on a 15X8 rim

(33" tire with 12.5" wide tread) (15" rim 8" wide)

Not sure if that helps at all but there ya go
