Came into a great deal on a set of wheels. 17x8 +38 and 17x9 +30 I’m lowered about 1-1.5 inches. What tires can I fit on there? I was thinking 235/45 and 265/40?
Any help is greatly appreciated.

The rear should work as is but may require a very slight rolling the quarter fender lip up. The front depends on the spring/shock combo you are using but most likely you will need at least a 5mm spacer with that mentioned tire combo.

Fitment question
I am new to owning an FC so not super familiar with what I can fit on it. Looking to run enkei rpf1’s in 18x9.5 +15 front with 255 tires and 18.10.5 +15 with 275 and maybe potential for wider at some point. My car does have origin 20mm fronts and 50mm rears. What would I need to get this fitment looking good?

Looking for a wheel tire setup for my 1990 Vert. I'm on Tein S-Tech Springs with stock alignment and don't plan on changing. Will also leave my fenders untouched. My goal is to have the most grip possible without overkill. For instance, if I won't benefit from a tire wider than 225, then I'll just stick to 225. I am also willing to sacrifice the cool stretched setup look for a narrower wheel if it offers more grip. For now, I am thinking 17x8 35 Front 215/45 and 17x9 25 245/40 Rear. Future mods will probably be a RB catback, test pipe, and LSD if I can find one. Nothing crazy, just for spirit driving. Any input is appreciated.

Amen brother, about time. 
Here's what I've learned:
Per RETed:
17" x 8" +27mm offset (+30 to +25 should work) with 225/45/17 up front
17" x 9" +20mm offset (+15 to +30 will work) with 255/40/17 in back
I'm particularly interested in the 5Zigen FN01R-C wheels which I think just match these values.
Note: after further research, I have learned that RETed's wisdom of matching the tire width with the rim width is actually considered a very good theory on handling improvement and is recommended by some guy who wrote some book that I am too lazy to re-research right now. Let's not digress the thread with who it was, but just to say that, yes, it appears to be very solid advice indeed.

Okay now i’m sure that this question has been answered like 500 times at this point but I am still lost. If I was to get 17x8 all the way around it is my understanding that anything over around a 32 offset is likely to be extremely tight and not fit. If it was to go with 17x8 for all tires with a 25 offset what tire sizes would I be looking for to make everything nice and flush.

This is the best that I can do to help. Likely. the best you can do is get close and use wheel spacers. Hopefully someone else will chime in, too.

Morning all,
I am really looking into running the Gold RPF 1 on my Red FC. I have fortune autos. Issue is the Gold is limited to these sizes and looking to run the optimal setup. Obviously not the best for off sets...
17x8 45
17x9 45
18x8.5 40
Ideally I would want to run these, they come in silver finish, they have black but I don't even see those offsets listed as they are "limited".
17x9.5 +38
17x9 +35
Any help would be much appreciated.

I have an '89 TII with coilovers, and I'd like to achieve a staggered look. I want the tires to line up with the quarter panel without sticking out from the fenders.
I'm considering using
Front 17x8 offset either +25 or 35
Rear 18x10 Offset 35 Rear wheel will have a Step lip
Let me know what you think
