Default 18x9.5 +45 - Any Chance

I'm currently running 18x8 + 40 with 225/40s all around lowered on NF210s - and I have had absolutely no rubbing.

I have a chance to pick up a set of used wheels that I REALLY like, but they are 18x9.5 + 45. From searching this forum, it sounds like the rear will work (with 255/35 tires - and maybe a 5mm spacer if there are caliper clearance issues), but the front sounds like a problem.

Is there ANY chance at all 18x9.5 + 45 rims can work on the front of a 2nd gen xB? Or, should I keep looking?

There's a chance they'd work, but you'll need to test fit to know for sure. You would definitely need to run stretched tires up front, and maybe roll/pull the fenders. I think the bigger potential problem would be rubbing on the inside when turning lock-to-lock.

I'm also guessing that being that wide, they probably weigh significantly more than your current 18x8 wheels, which would mean a decrease in acceleration, handling response (slower turn-in), and gas mileage.

Personally, I'd say keep looking.

Thanks for the feedback. I agree with your recommendation 100%. These are a classic wheel that was discontinued about 15 years ago - definitely old school. I found a set in excellent condition, but they are all 18x9.5 +45. I may buy the set, keep two for the rear, resell the other two and look for a pair of 18x8s for the front. These wheels are much more common in the smaller sizes (17, 16 and 15), but I really want a set of 18s.

Or, maybe I'll just stick with what I have for now and hope a set of 18x8s show up sometiome down the road.

If they're old school, you could do like I did and run 18's on the rear and 17's on the front.

I actually thought of that since they are fairly easy to find in 17x8.

So, assuming both are +45 offset, what size tires would you run with 17x8 in front and 18x9.5 rear?

225 or 235/45-17 front and 255/40-18 rear.

Use the offset calculator to see what the difference will be.


18x8 +40 ----> 18x9.5 +45
Change:
Inner clearance: 24mm less
Outer clearance: 14mm more

How much clearance do you have on the inside now? youre going to need alittle more than an inch on the inside. You can always use 5mm spacers but that means your new wheel will poke about 20mm out more than what you have now. Go measure.

Forsure youll have to stretch.

Are your fenders rolled?

I think I'm good on the rear outer clearance as many people run 18x8 with 15 or 20mm spacers. I'll have to check the inner clearance.

Without going to extreme measures (stretching, rolling, etc.) it looks like a lost cause on the front.

I'm about to get a Five axis lip kit installed, so I don't want to roll my fenders.

ooops. yeah, youre right


Im pretty sure youre going to have to roll the fender. maybe even pull the top depending on how low you are. These wheels will you make you hellaflush if you slam it just right.

I think with springs, youre going to have issues. Either the spring rates will be too low and cause you to bounce and rub, or the springs are going to be sitting too high to look good. probably make you pull some mexi flush style going on.


I dont know, its up to you

If you are dropped on trd's or nf's you should be fine, maybe a slight rub on u turns
because of that extra .5 wideness inside your whell wells.

I found another set that are 18x9 +42. So, that would five me 9mm more inner clearance and 3mm less outer protrusion. That's getting closer, but barely.

The front is my main concern. I'd love to find a pair of 18x8s with between 35 and 45mm offset for the front. The 18x9.5 +45 or 18x9 +42 would be fine for the rear.

18x9 +42 should work fine on the front, as long as you're only on a mild drop (Eibach Pro-Kit, Tanabe NF210, or TRD springs); and run stretched 225/40 or narrower tires. I don't remember if I asked, so remind me of your drop, and I might change my input... Best case scenario would be a staggered set of 18x9 + 42 rears and 18x8 +42 fronts, with 245/40 rear tires and 225/40 fronts.

I think with a +42 it will give u a flush look on the fronts but the rears are a little bit inside the fenders.

I'm on NF210s. Currently running 18x8 +40 with 225/40 on all four corners with absolutely no rubbing or turning issues.

There are some pics in my intro thread. The ones on the first page are before the NF210s, the ones on the second page after.

I'll be getting my Five Axis kit installed this week, as well as some Forjworks eyelids and my painted engine cover. I'll post some more pics once all that is done.

That's similar to what I have now. If I keep my current wheels, I'll add spacers to the rear to flush them out even with the front. If I get new wheels, I'll either go staggered or add spacers as needed - depending on what size/offset wheels I find.

Wheel specs are fine. Tire size will depend on drop.
You can PM me to discuss specifics, so we don't keep thread jacking.
