I can't tell you anything based on my personal experience but I did collect a few relative comments from others on this site.
For what it's worth...
19x10 +42 forgestar on all four with 285's no problem lowered steeda sports. Ton of room run them on the track never had a rub.
I have Toyo proxes on my Eibach pro lowered mustang. I run a 10 inch wheel with 295 30 19 that is 12.4" wide on a 47.5mm offset with no rubbing. Toyos run wider A lot of manufacturers
I have Front 19x9 (+35 offset) with 255/40 and Rear 19x11 (+42 offset) with 285/35. I'm also lowered on Steeda Sports. No rubbing whatsoever.
