Wheel lug torque spec

[B8S42011]

Shop installed my AG M610 wheels today. I believe they torqued them to 100 ft/lbs. I'm wondering what is the exact torque spec for when I re-torque them? Also, the oem tire pressure spec of 41 psi seems awfully high. Is that what I should set them at? Thanks folks.

between 80 and 100 is fine.

I typically torque mine to 88 lb-ft and have never had one come loose - however, I do check / re-torque after ~50 miles or so of driving. I think most shops go heavy on seating torque knowing that 98% of customers would never go back in 25-50 miles to re-torque the bolts.

I usually keep my 19" tires at 38 psi.

IIRC, 90 lb-ft is the spec. I usually hit 95 on mine.

90 ft lbs is what I use and as mentioned above, I recheck the torque after a bit of driving (same or next day). And as a PSA, if you're running aftermarket wheels with conical bolt seats, be sure to keep a set of 5 of the OEM ball-seat lugs in your trunk in order to attach your spare wheel/tire in case you get a flat. Do not use conical seat bolts to attach the spare wheel - it requires ball seat lugs!

OEM recommendation of 6.7 quarts of oil seems awfully high. Is that what I should actually use?

Also, can't take the time to google what type of gas I should use, or read the manual, can u guys assist? Thx in advance.

OEM tire psi on normal load is 39/33, or 32. Cant remember exactly. 41/41 is for a full car (5 adults) or towing.

[ModItNow]

I think 88 ft lbs is factory spec

Psi for tires is 36F/36R, full load is 41F/41R and wheels lug torque specs are 90ftlb, enjoy...

the spec is 90. It's in the manual.

I find 39/37 to be good for my PSS's, with just myself in the car most of the time.

I’ve run those pressures as well. I’m just reiterating what the sticker on the door jam says. Currently I’m using Bridgestone RE71Rs on my 18’s and running 36 because it’s a more aggressive tire and it works well. On my all seasons I run the pressures you’re stating and it’s perfect for those tires.

Owners manual says 39/33 for normal load conditions with 255/35/19 and 41/41 for "full load condition". I've been running 39/33 and getting good tire wear but as most will tell you, it doesn't hurt to play around a bit and see what fits your driving style best.

[Silver Streakin]

It was 89 ft lbs with my B5, 7 and I’ve used that for my 8. (No owners manual)

Tires ... no way I’d use that low (low 30s) in the rear.

Thanks folks. I just verified with the owners manual. Torque spec is indeed 90lb/ft. Tire psi for normal load is 36f/33r and 41/41 for fully loaded. The sticker in the door jam only says 41/41 and that's what the shop set them to. Boy it was a bumpy ride back home lol..

39/33

[B8S42011]

39/33

Perhaps that is for the 18" wheels. For 19", I am certain it is 36/33.

Not sure why this is always some debate... straight from the owners manual for 19” 36 front 33 rear.

Well there you have it. Different years, different specs. I wonder why that is.

What year is this manual for?

2012... I always wondered why tire places had different specs than what my manual said so I always made sure to specify. I’ve forgotten before and when I got the car back I could definitely tell a difference even with it only being 3-4 psi higher. Wonder why audi felt that much of a change was needed since there isn’t much difference between the two as far as weight goes.

I can understand the 3-4psi, I can tell a little difference from 41 down to 39. Maybe I’ll bring mine down to 36 and see how it goes.

[hilmar2k]

My 2014 manual also calls for 39/33. Obviously they made a change, as the newer cars have a different spec. Maybe they had issues with the lower pressure? I'd be inclined to run the higher even if I had a '12 or older with the lower spec in the manual.

Thanks you for this tip. Didn’t think of it!

Not sure where jygesq got his info but oil fill capacity with filter change is 6.6 quarts. Pg 284 in owner's manual, 2011 S4.
