265/35 on 18x9.5 +38
 

I'm getting coilovers as well as 18x9.5 +38 wheels this weekend. However, after searching on the forum for so long, I still havent come to a decision of how wide I should get my tires. People say don't stagger tires but I also want lots of grip in the rear so thought I might go 265/35 in the rear and 255/35 at the front with some camber adjustment.
My question was is this a good idea and will I be rubbing with 265/35 in the back on my wheels?

EDIT: I am no longer getting coilovers (temporarily). I've got 18x9.5 +38 57DR wheels all round. I am on lowering springs and lowered by about 1.1 inches (30mm) and I am looking at having a lot of grip at the back for my turbo. I've decided I wanted the ability to rotate wheels hence I am going to get 255/35r18. I am going to be putting MPS4.
However, now my concern is if 1.5* camber (from cabler bolts) in the front will be enough to avoid serious rubbing issues.

with a +38 offset, you will need some camber to fit them nicely. Also depending on which brand tire you get will also dictate the clearance as well. Some tires run wider than others. I would also suggest you get rear toe arms as well if you dont want to chew up your brand new set of tires...

imo i would suggest going with a 255/35 all around.

If you give us more info on your setup, and why you need to run that wide of tire you will likely get a better and more direct answer.

Going from 255 to 265 will have an almost insignificant amount of impact on rear grip in comparison to how you have your suspension setup dialed in. Unless you're a track ace using every inch of your rear grip with a perfectly setup suspension for the behavior you want, I doubt you would notice much of an impact.

Stick with 255/35 unless you have a clear-cut reason to bump up.

Thanks for the replies guys!
