I'm in the market for new wheels and I thought, "Eh, these come in 10.5; why not?"

So what I WANT to do is go up to 19x10 in the front and 20x10.5 in the rear and proceed to never break traction again. Basically, I want to be able to flail wildly on the steering wheel while mashing the pedal in first gear and remain attached to the road. It's a pipe dream, I know.

Anyway. I haven't bought them, yet, but I want to. I've done a bit of research on the forum, and this is about what I've come up with:

The 10.5s *should* fit, as far as I can tell.

The rear is stock 19 x 9 ET 22, so would require 38.1 mm more width between the inside and outside. The smallest offset I can find on the wheel is a +27, so it would definitely have to be spaced. I've heard of stock rims on 20mm spacers with no issue (effective ET 2), which means I ought to be able to space up to 25 mm for the same effective offset (+2). That leaves an extra 13.1mm on the suspension side, which shouldn't be an issue.

In fact, I think I've heard of XF owners running 10.5s on these forums, but I might be wrong.

Now, those front tires are a different beast.

The front is stock 18 x 7.5 ET 37, so would require me to pull 63.5 mm out of my *** to go up to 19 x 10. The smallest offset I'm coming up with is +25, and that might be a problem. The biggest spacer I've heard of on our front wheels is +15 (effective ET 22), which means I could only space 18mm for that same ET 22. That leaves a pants-shitting 41.5mm of wheel on the suspension side; I don't think that's gonna work, but I might be wrong. I've heard of someone running a 19 x 9 ET 30 on the front, which would've put the suspension side 45.1 mm further back than stock, but presumably those were spaced, and I don't know if they have any rubbing issues.

What are the largest and smallest offsets you guys have heard of without rubbing on either side? I just don't have enough data for this.

I'll gladly roll my fenders or whatever for those disgustingly-wide tires, and I'll stiffen the suspension if necessary (which, with rubber band tires, means I will be very, very intimate with the road...). I just want to know, flat out: what can I fit in there?

 

Here's one with 20" all around...

It's the American way: if enough is good, more is better. Gotta help keep the tire/wheel salsemen's yacht payments current.

Don't forget, 100 years ago 20+ wheels were common.

 

I'm more worried about the width than the diameter.

 

To be fair, if I can run wheels in this size, "more" will never actually be an option...

 

here is what 20x10.5 looks like on the rear. Enjoy!

 

Are those Niche Targas? Did you have to space them or do any fender/suspension work, or was it just a bolt on? Any rubbing issues?

 

The issue with too large a tire is the leading edge of the tire striking the wheel wheel when raised. Anything over a 27" diameter is liable to be problematic.

 

Yeah, I definitely wasn't looking at going above 19 in the front and 20 in the rear.

 

-Yes
-No spacers front or rear.
-Bolt on and proper hub size
-I have SRT6 springs with the thinnest spring pads and ~60+lb of stereo in the trunk
-the inner lip of the rear fenders is pushed up out of the way a little. not noticeable standing beside the car.
-Little rub here and there but other factors may be the cause when it comes to my car.

 

Awesome. What offsets are you running? 25 is the minimum (as far as I've seen), and I can't imagine you went with a MORE positive offset in the rear. What are you running in the front?

 

Remember, the larger the rear tire on a NA car, the slower it's going to accelerate.
I'm just sayin.

 

I run a 19x8.5 , 32mm offset on the front with no spacer. It sets out to the edge of the fender and rubs a little on full turns. There is not another 1.5 inches to work with on the inside of the wheel. 19x10 isnt gonna happen unless you want an inch sticking outside your fenders like the ricer hondas.

 

Thanks for the heads up! From a small amount of personal experience, though, I find that acceleration is pretty far down on the list of things that make me enjoy a car's handling.

That being said, I plan to offset that to some degree with work on the intake (either a big CAI or a proper ram setup) and exhaust, and I expect being able to apply more torque without breaking traction (I chirp the tires... often) should help, too.

 

Also, since you're running a +32 offset and mine is stock 25, that would give me 7mm extra in the rear; with a 9-inch tire (10 would be overkill, but that's kind of the point), that means I'd only be pushing about another 7mm into the suspension side, which is more than enough for a spacer to cover; I can deal with 7mm of protrusion, or 20 with a 9.5 inch wheel.

Honestly, I'd be fine with sticking out of the fender well a bit if it meant better handling. When it comes to movies, story is king. The rest can be spectacular, but it can't make a bad story into a good one. When it comes to gaming, gameplay is king. The story and art can be amazing, but they can't make a bad game into a good one. When it comes to cars, shouldn't performance come before looks?

 

Your best bet in this order......74mm throttle body, cai from needswings and a tune from eurocharged. Thats about all your gonna get for the n/a as in a power increase.

 

32 on the front brother....20x10 25mm on the rear with a 10mm spacer--

 

A couple of pictures

 

Personally, I prefer a car that does both. Since an "NA" Crossfire with (stock size tires) will go through a slalom faster than a Ford GT, I'm OK with it's handling.

 

Yeah, from the pics, you're pretty flush, but I don't think another 10mm of protrusion (around 1/3 of an inch) would push you into "ricer territory"; I wouldn't be looking to extend much further than that.
