Vossen CV4 + AP Racing BBK

The 305's will look sick but personally I wouldn't get them. So hard to find and super expensive plus God forbid you get a flat tire one day it's going to be difficult to find anyone that carries them or can get them asap.

It's impossible to find a manufacturer that sells the 265/40r/22 & 305/35r/22 combo.

Pirelli Scorpion: nope
Yokohama Parada: nope
Nitto 420s: nope
Hankook RH07: nope
Continental Cross Contact UHP: nope

Anyone have any recommendations??

Don't get an 11.5" wheel is my recommendation, 10.5 is really common, 11 is somewhat common, and most of the guys who go wider go straight to a 12" section and a 335 tire.

I'd say either for 10" square, or 9.5 front, 10.5 rear.

If you really want to push the limits measure the rear wheel well clearance and see if you can cram a 12" wheel under there, Then you can go 10" front and 12" rear.

Keep in mind with a 12" rear the only tire you have available is a 335/25/22 which is a pirelli P-Zero which is about $900 a tire.
 
I think Pirelli still makes those sizes, but it's weird that I don't see any sellers that stock both. ie, TireRack has 265/40/22 and Discount Tire has 305/35/22.

Honestly, if you downsize to 295 or 285 rear tire, you have a lot more choices. Other than the look, a 305 tire is unnecessary. We don't make enough power, especially with AWD to actually need that much tire. Both those sizes will work with the 265/40 front.

That's actually why I swapped out the Pirelli's. Wife ran over a piece of scrap metal because there's a lot of construction around here. Took out one tire and no one could get me a replacement for some time. So I swapped out to 295/35/22 Yokohama Advans.

Christ, I totally did not consider that and you're absolutely right - as incredible as they'd look, it's just not worth the risk. 10.5x22 + 285/40r22s all around it is then.

Fantastic point, Rip!

Ya I would go with the 285 or 295. Plus you have a bbk like I do. I blew out a tire a few months back and the spare wouldn't even fit on the rear but luckily I got it towed to a shop and they had my 285 in many diff tire company options. Imagine blowing a tire and not being able to get your 305 tire and then not being able to drive with a spare. Huge mess
 
I think I'm in the final stretch now, and I've drifted away from the square and back towards staggering. Only this time I've reigned in the overly-ambitious, overly-aggressive style that I was originally after and I've settled on a set up that will function flawlessly with AWD, as well as be easier to replace if/when something goes wrong. One last sanity check, please. Here we go:

Niche T01 Touring (matte black)
9.5x22 ET42 F
11x22 ET48 R

Pirelli Scorpion Zero Assmetrico (identical diameter!)
265/35r22 F
295/30r/22 R

Maybe there's something I'm not noticing here, but, in theory, this should be a really good combination.
 
Speedometer will be off by 5% or so. That's the only downside. New tires are 28.9" tall and OEM is 30.4" or so. Your speedo will always read fast. My tires are undersized right now as well by a similar amount. I've gotten used to the speedo reading high. Keep in mind the odometer will read high as well.

Other issue is that your wheel gap will increase since the diameter is smaller. It will get bigger by .75" which is noticeable. So if you don't lower your car, it will look a bit weird. It makes the car look lifted since the wheel gap is bigger and the wheel smaller. You'll get the Cayenne look.
 
Yep, already have the ride height covered - H&R springs have already been installed.

I plan on getting the speedometer recalibrated in the end.
 
How will you get the speedometer recalibrated? Doesn't that require changes in the ECU? Will the dealership do this?

And when I say lower the car, I meant more than H&R. 1.5" difference in rolling diameter is pretty big. H&R springs lower maybe 1.2", you will have .75" more gap. So your car will only look .45" lower than OEM which isn't noticeable. If you're ok with OEM wheel gap, no worries. But if you like your drop with the H&R's, it won't look that way after the smaller tires.

I have no idea how it's actually done. I got a speeding ticket 13 years ago and I remember that I was able to get out of it by taking it to a place for recalibration. Gave me a paper to take to court and everything. I'm assuming that it's possible to do since kits are available online.

The FX is not like standard domestic trucks which can have the speedo recalibrated with a flash tuner.

As far as I can tell no G35, or 350z has ever been able to get their speedo adjusted, everyone just seems to say it is impossible.

HOWEVER, the titan guys have tested multiple methods, and although very few have actually bothered doing it, it appears that hypertech has finalyl developed an inline speedo calibration adjuster which will work with the titan, and will HOPEFULLY work with our vehicles as well.

Discussion here:

product here:

Keep in mind once again, that you are going into uncharted waters, there is currently no FX35 owners who have successfully made this work, and I almost dare say there is no 350z or g35 owners either.

---

On that note I already have the tool inbound to try it out on my 2008 FX35, my new tires are going to be roughly 2" shorter than stock (i'm going from a 30.4" diameter, to a 28.1" diameter). I was going to update everyone if it works once I actually get a chance to try it out. At $200, its not cheap, but if it prevents my odometer from climbing at like a 10% higher rate then it is worth it.

It is super standard for guys with lifted trucks, cause they go from 30" tires to 40"+ tires depending on how aggressive they are going, so at that point the difference is shocking to both the speedometer in your car as well as anything which uses distance calculations, so fuel economy readouts, distance to empty readouts, your Odometer, trip distance, etc.

Can get pretty annoying when you have only gone 10 miles, but your stupid trip calculator says you have only gone like 6.
 
On the first gens, they reset the speedo and odo somehow during the recall for high readings. I have no idea how they did it, I'm assuming they flashed the ECU somehow.
 
Hmmmm very interesting, hope it all works out perfectly bro

Shadow is right these will look funny even if your dropped on H&R's. They will look like rubber bands especially the 30's on the rear. Personally I would stick to 40's.

I know it isn't possible even through UpRev software.

I think for the speedo recall they just adjusted the ODO and tightened the tolerance on the speedo, which can be done by a lot of people, there are guys who you can send your instrument cluster too and they will adjust your ODO to whatever number you want and ship it back to you.

My next plan if that Hypertech module doesn't work is to send my instrument cluster to someone who does that and see if they can actually physically alter my speedo to reflect the smaller diameter tires.
 
Ok, the hell with it. Screw staggered, I'm going squared. No more changing my mind. Good lord.

Parada Spec-X on 285/40r22 x4
Niche T01 Touring 10.5x22 ET42 x4
 
Squared will handle better. Good choice. 40s are great

Did you order wheels yet? go 10.5 all around. They fit
