ive not heared of any bad things happening, and thats on most dub related forums, (correct me if im wrong) the surface area that connects to the road stays the same, its just the sidewalls that are different.
i have just fitted 225 40s to a 9.5j rim and they look the dogs IMO safety wise? well, ive read nothing like i said above really bad happening its just what some people say, whatever their reason may be to criticise, the yanks have been running stretch for ages now and people continue to do so over here.
im sure if something happened people woud stop doing it right?
