I own U.S. Off Road, we manufacture winch mounts mostly for Toyotas and sell a bit of everything.. not really for VW's so I'm not pushing my business...

But to give you a bit of background so you know where I'm coming from.....I've had all kinds of off road rigs..Jeeps, tons of Land Cruisers, etc, trucks of all kinds and plenty of performance cars, pro tourers, Euro, hot rods..whatever. Some trucks eat tires, some cars have wear issues... there is always one model here and there that just isn't set up exactly right from the factory... bad design, minor oversight.. whatever. I've raced on dirt and pavement, drag, road, ovals and currently have my 6 yo racing karts. I fight the tire battle all the time. I thought I understood tires well, until we bought Touaregs. Anyway...regardless, this VW has kept me learning new tricks to keep it happy.
My wife's 2013 TDI with 107500 miles as of today.
Both of the T3's I've had eat tires and I've read on here much of the same. VW even chipped in on a pair at 16k. I finally got tired of the OEM tires. Both of ours came with Pirellis which I kept on the 11 (traded on the 13) but then we tried the OEM Goodyears on the 13 as the third set...same thing, done in 25-30k. Uneven tread wear, vibration of course. We had the dealer do routine alignments often. Didn't matter. So at that point we are going through tires far too often, about half life, the thing vibrates and you had to stay on alignments. No fun.
Then, on the 4th set I tried the Nitto 421Q and with about 20-25k on them 13 months later (my wife drives it, she's a Realtor) they still ride great, handles well, wet included,
maybe a touch noisier than the Scorpions but I like them a lot as they have a lightly more aggressive tread (hence the noise if any) so when my wife shows ranches, etc it's not as prone to tearing up tires or getting her stuck (the ranches have only occurred in this last year). I haven't checked depth but I have to believe they will go all of 50 and maybe 60k. My wife isn't hard on tires overall and stays off of the curbs, etc. Lots of highway miles.
I think the torque of the TDI, all wheel drive and being 5000lbs empty all contribute.
I believe the Nitto specs really tell the tale and so far....

Having said ALL of that... the Discount Tire here has some good guys, I've done tons of commercial and personal business with them. We road forced every set to no avail until I found the TSB here and poof, no more vibration. If my memory is correct, my old E36 M3 required the same process as the TSB, maybe it's a German thing. I don't have vibration problems on my 2010 Yukon 2500 (7700lbs) which has aftermarket wheels/tires. My past trucks didn't vibrate. All were balanced at the same DT.
Just my experience and yes, we love our Touareg. I'd like to find an older TDI for me as well.
