2016 SQ5 19" summer wheel/ tire advice/ options

[Bobcdn]

I have looked at the wheel and tire thread- but all the 19" options are for winter setups.

I would like to run 19" wheels on our 2016 SQ5. We were so tired of the ride with the 21" wheels that we have left the winters on for the last 3 years! So I figured if we went with a light weight wheel and a good tire that we would be happier.

Looking at the neuspeed wheels but would consider others as well.

So my question is what are the wheel specs I should be looking for? Width, offset, centre bore. Also tire size- I would like a decent size side wall. May eventually lower the car- but for now it is just a stock daily driver.

Thanks.

B8 SQ5 21" stock is 21x8.5 et33, with 255/40r21 tires. So if you want to just switch that down to 19", now you're 19x8.5 et33. The B8 and B9 Q5 19" stock is not that size, they are 19x8.0 et39, with 235/55r19 tires. That's a 6mm inward shift. But they are straight no-thought bolt ons.

While there are a number of A5/S5 as well as A4 allroad wheels in that size, you have to remember the A4/A5 wheels are a lower load spec and different radius lug seat:
A4/A5 - 650kg load, R13 lug
A4 allroad - 670kg load, R13 lug
Q5 - 730kg load, R14 lug

The other wheel specs are normal Audi specs: 5x112 pattern and 66.5 center bore.

The "MICHELIN® Latitude® Sport 3 255/50R19 103Y N0 BSW" is the Macan spec tire, so same 255 wide and 29" diameter, but for 19" wheel. Supported on a 7.0" to 9.0" wide wheel, so a x8.5 or x8.0 wheel would be fine in your looking around.

Thanks for the info guys. I might even go with 18s if I can find wheels that will clear the huge front calipers!

[Bobcdn]

Used the info from Smac770 and played with the wheel calculator from Norskie and this is what I am thinking of;

https://www.willtheyfit.com/index.ph...h=9&offset2=40

18x9 et40 Neuspeed RSe11R with 255/55/18. Says the set up will be 13.4mm closer to the suspension strut than the OEM 21s. Will this fit without hitting the suspension?

Thanks.

I am running rims from A6, this is the part number 4G0 601 025 S These probably won't work for you as they are really close to the Callipers. The Callipers of the SQ5 are bigger than the Q5.

The tires that are on the rims are Bridgestone Potenza Sport 235/55/19

Just checked and the rim size for Both SQ5 and Q5 look the same 8Jx19 ET39.

[Smac770]

The B8 Q5 front brake options include the traditional 320mm and 345mm TRW single piston floating caliper configs as seen on the B8 A4/A5. Additionally, the B8 Q5 has the 380mm ATE 2-piston floating caliper system. This is used on the SQ5. The 380mm system is listed as an 18" system, meaning Audi 18" wheels will fit over them.

The SQ5, for looks, has 0.5" more track than the Q5. This is implemented by using a lower wheel offset. The Q5 uses x8.0" wheels with et39. The SQ5 uses x8.0" wheels with et27 or x8.5" wheels with et33. I assume the SQ5 has flared fenders to accommodate the wider track. Also note the SQ5 winter wheel is 19x7.0 et37.

If we look at the type 8R wheel and tire guide, we see the 18x8.0 et39 wheels are not restricted from the 380mm brake system, while the 17" wheels are. We also see what we already saw in the catalog, the SQ5 is only listed with 19", 20", and 21" wheel options. This would be because none of the 8R 18" wheels are made with the necessary offset to set the SQ5 track width. Not because an 18" would physically fit.

So an Audi OE 8R 18" et39 wheel is fine to put on the SQ5. But is a Neuspeed 18" et40 wheel going to clear the calipers just as well? There's no way to know without trying them or somehow getting a map of the spoke curvature to compare against the caliper outline.

As for the inward intrusion, yeah, that config has the outer wheel lip and outer tire face right where stock SQ5 would be, but has the inner wheel lip and inner tire face both a full 1/2" more inward than any stock Q5 or Macan (at least the 2.0T) config. Do you have a 1/2" on the inside of your 21" wheels and tires to give?

255/55r18 on 18x8.0 is a stock Macan config it seems, but it's on a much lower offset, et21. Keep in mind the Macan puts the outer tire face about 1/2" more outward than a SQ5.

I have the Brembo 4 piston callipers on the front, which I don't know if it is sticking out more than the ATE 2 piston. The Rims that I have are 8,5J x 19 ET45

[elRayRay]

FWIW, I've had 18" x 8.5" ET 45 on my Q5 that has the 4-pot Brembo calipers and 345mm rotors with no clearance issues anywhere. I thought the SQ5 has 360mm fronts, right? I imagine if the 18" setup fits over the SQ5 brakes, it would come down to the inner spoke profile of your wheel, as mentioned above.

[Smac770]

B8 SQ5 fronts are 380x36.

Oh, yeah, B8.5 Q5 fronts are still 320 and 345, but Brembo 4-piston fixed caliper configs inherited from the Macan.

Not sure if there was any extra room between the wheel/ tire and strut or not. The wheels haven't been on it for 3 years. I have a set of 18" replica peelers on there now. I guess I could throw one of the OEM 21s on before I sell them to see.

I also gave Neuspeed my VIN and they checked and said their 18" RSe11R would clear the calipers- but were unsure if the extra 13.4mm inward would contact the suspension or not. I told them I would ask on here to see if anyone knew. Has to be a proper fit because we are not legally able to use spacers in Ontario.

From Neuspeeds site;
VERSION 2.0.

Based on our original NEUSPEED RSe11 wheel, this newly, redesigned version allows for more brake clearance, by cutting out weight.

BBK FRIENDLY.

Every RS Wheel is specifically designed and engineered to be “Big Brake Kit Friendly”. Installation of most big brake kits will not require the use of adapters, spacers, shims, or any other safety-impairing devices. Whether you have factory or aftermarket big brakes we have something that will go over them with ample clearance.

Thanks for all the info. I plugged it into the wheel calculator and it says the Neuspeed 18x8 et40 would be 19.7mm closer to the strut/ suspension than the Audi18x8 et39. So looks like I will need to put one of the 21" wheels on to see if there is more than the 13.4mm (1/2") room or not.

LOL... sold the OEM 21" wheels/ tires yesterday... realized today I forgot to put one on to see if there was 1/2" or more clearance between the suspension and the OEM 21" wheel/ tire. Is there anyone that can check theirs for me... please?

Any issues with fitment for 19x9.5 +22 with 285/40r19 (16 SQ5)?

Should be good! I run a winter setup of 19x9.5 et20 (effective after spacers) with a 295/45 winter tire and it clears everything. Your setup will be a little shorter and narrower . Maybe someone else can confirm too but it should be just fine.

Nice! I thought about 295/40r19 but I think 285 on a 9.5 is plenty for me. Lots of miles in road trips and an in all weather conditions. The 20/21’s look good but I like the 19 with a 40 series. The 45 probably looks great too.
Thanks man!

Finally ordered a set of 18 x 9 ET40 A01 APR wheels for our 2016 SQ5. They are on sale right now for $139.63 each. Going to run 255/55/18 tires.

I was watching the YouTube show Stay Tuned with Tony Angelo and he put the same wheels on a Mercedes and said they were on sale. They are flow formed the same as the Neuspeed wheels I was looking at.

Thanks for everyones help with the technical information.
