Need advice on tire dimensions for a staggered setup
 

Hello everyone,

I need help with calculating tire sizes for a staggered setup. I've ordered Rota Grids - Front: 18x8.5 5x100 ET44, Rear: 18x9.5 5x100 ET38.
Since I'm still waiting for my wheels to arrive, I'm having trouble deciding with tire sizes.
I did some research and I couldn't find any reasonable anwsers, but I was thinking of going 225/40R18 for the front and 245/40R18 for the rear.
Should I be looking at 245/35R18 at the rear? I am going for a bit of a stretch on the tires, so no need for extra wide tires.

Any help or tips appreciated.

Thanks in advance!

Edit: I am running BC Racing coilovers and haven't touched the ride height yet. It is sitting at the height at which coilovers come from the factory. Will be looking for a nice, flush fitment.

9.5x18 ET 38 will poke out from wheel arches...

My advise would be to not do staggered setup, but it came too late, as you have already ordered wheels.

Save yourself grief and take the wheels back and go square setup.

215/245 or 225/255 need same diameter.

225 squared is classic NA setup
245 squared classic FI setup
225/255 is for the bad ass FI setups.

In the rear with a 245 it will be pretty flush with about -1.5 degree camber, 255 will poke unless he does more camber
