my current rear tires set up is 275/35/19 on 19x10 +40 rims. just wondering if going 285/30/19 would be ok? i'm sure its ok but would like to just double check and also will i need camber kit? thanks

 

If you haven't dropped your suspension you won't need a camber kit, if you have lowered your suspension you probably will, and you must get it aligned if you have lowered it. If you have 7mm to the inside fender edge w/ your 275s you can go to 285s as long as the new tire doesn't run extra wide. The tread block width should be listed on the tire makers' site.

 

Oops I forgot to mention that I'm on eibach pro kit.

 

Lets see pictures of the rear side, I want to know how to 275 on the rear looks like on the G.

 

Sorry no pics, cuz my winter tires are on and the 275 are bald and will be replaced with 285 if it fits without getting camber kit or spacers...

 

Oops, glossed over the part where you stated 285/30/19s, I wouldn't recommend that thin sidewall, I'd run 285/35/19s, ride won't be nearly as harsh.
