Wheel "inset" and offsets - SQ5

[beasq5t]

Based on willtheyfit.com SQ5 stock inset is 130mm -- how much more room is there before there would be rubbing?

I want to go down to a 20" wheel but would like to go wider than stock but don't want any rubbing or to damage the AWD system.

Also, is it okay if rear wheels are spaced out further than the fronts? Either by different offsets or through the use of a spacer?

20x10 et+25 with any tire up to 295/40
For rotatability, get all the same offsets. You can use spacers in the back if you want, but you won't need them with the proper wheels.

[colby7]

I run a 285/35/21 with an inset of 150.7 according to willtheyfit.com and I don't have any rubbing.

[Mops@Nemesis]

I always space the rears out. Currently at 6mm wider at the rear.

[sammi_s]

My next wheel setup will be 21x10.5 front and 21x11 rear ! Offsets I can disclose shortly once I'm done measuring lol.

But I know this can work !

Thanks for all the replies. I'll keep you updated with what I end up with.

I never was very confident trying to figure all that out. I've read up on it, and tried to follow you guys on here to learn more, but I just did trial and error. I've always run stock wheels, from my old Q5 5-arm polished, to 2 sets of peelers, to the stock SQ5 21s. And they've all had 33 offset. I never knew what the ET stood for, or the +/-

I think all the stock wheels are ET+33. I did spacers by trail and error. Tried 20mm in the rear and it was too much. So dropped down to 17.5. I like all 4 wheels to be the same. I did the same 17.5mm on the old Q5 as well as the SQ5, and I like how it turned out. It's aggressive, and not conducive to tucking, but I don't particularly like the tucked look. It's pretty flush. I'm assuming you just add the 33+17.5 and come up with a +50.5 offset? I'm assuming that means from the hub.

Nope. . .. . .You would subtract 17.5 from 33, yielding an actual 15.5mm offset from the center, or ET+15.5.
Zero is the center of the wheel. Positive numbers move the wheel inward (tuck), while negative numbers move them outward (poke).

[ThunderDent]

Thanks man. That's good to know. It is still a confusing thing for a lot of peeps to try and come up with what fits/which tires when you are starting from scratch (i.e.- going the aftermarket route/changing up tire sizes, etc.)

What fits? What rubs? What clears calipers? How far out is it coming? Rolling diameter change from stock?
There is a lot to consider, but that's why we have all you smart wheel peeps to pick your brains. 😝

[SQive]

I've got the diameters, widths, offsets, and tire sizes down. The caliper clearance is always a variable, based on the type of wheel and if it's for the SQ or BBK's.

I'm curious about what sizes you intend to use for tires? A 275/35 - 315/30 combo would work, but the 10.5" wheels would make the fronts look pretty stretched. You do realize that going with a staggered setup on Quattro is pretty tricky, right? You have to get the same rolling-diameter front and rear, or it can cause damage.

275/30/21 ... all around !

I already have the tires on my other 21x10.5 and perfect works.

I know how Quattro works and I know the variances, the rotating diameter can't be past a certain point. And at .5" nothing will happen.

It's fine.

Has anyone tried running 265/40R21 on the OEM wheels vs the stock 255/40R21?

Instead of buying new wheels, I am considering upsizing the tire so I can get an all season tire. Any issues?

Actually -- looks like the 265 is for a 9 to 10.5" wheel... so wouldn't work for the stock 8.5" width.

Nope. They fit fine. Most people on here using the stock 21"s move on up to the 265.

Thanks @sqive. Does anyone have pics? Does it balloon a lot?

Do you mean is there a sidewall bulge? It depends on the tire. It's not stretched at least. There are many benefits of going with the 265:

- more choices
- better choices
- fits better
- looks better
- more tread on the ground
- provides a little rim protection

Some of those may be opinions, but you asked.

265/40R21 101Y

Michelin Latitude Sport 3 Summer performance tire

(It's the Mich PSS tire made for the heavier CUV/SUV)

These come standard on the Porsche Macan 21s.

Best tire I've ever had on a vehicle. They look and perform awesome.

I'm thinking of purchasing some Vossen wheels. Vossen VFS-5.

Has anyone had experience with Vossen and or comments?

Going with 20x9 ET25 and still deciding between 255 or 265 for the tires.

Our main use of the SQ5 is a "utility" vehicle - camping, trips to the snow, etc.

I'd highly consider these. Similar look, better build, better finish, lighter, less expensive.

Thanks, hearing mixed reviews on Vossen so will be looking into the bbs ci-r as well.

I have a set of CV3 on my A4 and love them. I think one is bent but I'd say just as durable as any of the BBS I've had. I'm looking at SQ5 too with 20s and I'm thinking 275 40 20 or even 295 40 20 on BBS CI R or AG 510. H&R springs too. Test drove one with springs and Miltek..........oh man it was great. Sound is unreal.

[beasq5t]

I think I'm going to end up getting the HRE FF01 -- still need to decide on tire size. I thinking of going with Michelin A/S 3+ but not sure if it'll be 255 or 265.

I have a glacier white metallic with black optics -- thoughts on the liquid silver vs the tarmac wheels?

I actually just picked up a Glacier S3 with BO, and my first instinct was silver CH-R. So I say liquid unless you specifically love the storm trooper look. Plus tarmac more super dark graphite, so it's not going to tie in with your black trims.

Mops,

I'm going to order some custom wheels in 21x10.5 all around. What is the difference between front and back to get the wheels at the same poke? Some say 5 mm others say up to 15 mm difference.

I think I'm going to go 21x10.5 et 25 in front and 21x10.5 et 15 in rear. But might consider et 20 in rear for less poke.

Thanks for any insight

Camber plays a HUGE role here. Are you dropped? Adjustable control arms? Camber matching front/rear, 5mm is plenty. Here is ET20/17 with nearly matching camber...

NO.-5499 by Audiyos, on Flickr

Here is ET20/14...

[apsuard]

I'm lowered on H&R springs but stock control arms. I'm leaning toward 21x10.5 et 25 front and 21x10.5 et 20 rear. That should look stellar. I love my VFF 103s but would like a wide square set up.

@apsuard So your camber is pretty well in-check. The 5mm variance will be very nice. Please let me know if I can help you with the wheels.

What tire size do you plan on running?

As Mops said, camber will play a factor on what width offset you can run. Same wheel and tire size as Mops but his have a few more mm of poke and some more negative camber.
285/35R21 tire on 21x10" ET23 with adapters and am at -1.9 degrees camber all around. That the the most amount of negative camber I can have as I have the adjustable control arms up front. I think without the control arms the fronts would be around -2.2 or so.





And how it sits today with a few mm lower.



Yes I admit, I'm mainly pic-whoring but curious as well to see what the end set up is with you going with 10.5" ET25.

[apsuard]

I'm going to go with the new Vorsteiner forged line I think. 21x10.5 et 25 front and 21x10.5 et 20 rear. Pirelli Pzero in 295/35ZR21 all around

You should go with 5mm spacers in the rear and square your wheels.
That way you can get more mileage out of your tires through rotation.

[mmth_ski_bum]

If you're going full custom, then concavity will also play a part in offsets, whoever is building your wheels can play around with the measurements.

As others have said, if you want to rotate tires, than keep it to a square setup with spacers.

For example, I'm running 22x10 et22 front, and 22x10 et26 rear, but the wheel face profile is different.

Ordered the HRE FF01 20x9 et25 with 255/45 Michelin A/S 3+. Should have them mounted next week!

EDIT: Looks like HRE is out of stock! 12-16 week wait time... will need to find a different set.

Anyone have suggestions on which size spacer to use in the rear so poke is the same as the fronts?
