Would an 18x8 +45 work? A lot of the wheels I'm looking at are that size. No +48 mm, at least for the ones I like. The chart on the first page says they will fit, but I'd like to hear from people's experience. Thanks.

Picking up some 17x8 +48 ultraleggera sometime this week. Was planning on going with 235/45/17 DWS06's but now I'm starting to second guess the fitment. Still running stock suspension but may go with konis + new springs in the next few months, not sure how they compare for clearance with the stocks. Thinking a safer bet would be the 225/45/17.

I have that exact setup on my wagon (17x8 +48 OZ wheels with 235/45/17), significantly lowered from stock. I'll get some very very minor rub in the rear, but not enough to worry me. Great setup in my opinion.

 

That's a really meaty 235/45/17 too, as some 235s are actually wider than others.

Ordered some 18x8 +35 wheels. Hoping to mount 235/40/18s on them.

 

Suspension is stock shocks with H&R springs. I don't mind a little bit of poke, just don't want any rubbing. What should I prepare for?

 

I've looked at every fitment photo I can find of similar setups, and it's insane the differences in looks and mods. How does that make any sense?? Some fit this size and apparently only roll the fenders. Others say you'll need to roll+pull+mega camber...

 

What the f am I missing in understanding this?

I have this exact same wheel/tire combo. I'm on BC coilovers though, so I have adjustability there. Can't speak for spring/strut combos, but I have zero rubbing or issues with clearance. I chose this wheel/tire set up for minimum maintenance, and maximum function/aesthetic.

 

Let us know if you end up with 235/40s, and what your experiences are.

Mine is a sedan. Any idea on fitment differences?
