Speedos normally over read actual speed by about 5% so fitting a slightly larger diameter tyre often has the added benefit of making the speedo more accurate.

Always check against a GPS device on a level road.

Actually can someone confirm if the tire noise is normal? So when turning either direction at very low speeds, around 5mph, I cam feel the tires. They’re not rubbing the fender but I can feel them sort of rubbing on the pavement through the wheel. Does anyone know what I’m talking about? Is that normal for AT tires?
If your Touareg is like mine, I believe the "noise" you are hearing/feeling is the power steering doing it's thing at low speed and RPM. I was concerned when I noticed this on my vehicle but that was 70k miles ago. Still making the noise and working fine!

275/55/ 20
31.9"
2011 TDI Execuline

Long time lurker. Finally pulled the trigger and bought a 2011 TDI Execuline. Had almost new snow tires on 20" Pike Peak rims so I needed tires now. I searched for 17 and 18" OEM rims locally. Nothing available . Had a friend with a set of 275 55 20 Bridgestone Duellers that he was not using. Not alot of tread left, but enough to pass government safety inspection. Perfect set to do a trial fit before buying new.

Would never have attempted this large without having read this entire thread. Big props to @ncburch22 who had reported a fit on the same size.

They fit and no rubbing on full or half lock: forward or reverse. I dont have a baseline reference to compare the drive as it had 275 45 20 snow tires on when I took delivery. The drive is definetely more truck like. Reminds me of my former 2004 4Runner. The truck I never should have sold.

Will decide in the next week whether to buy new tires in this size or stock size. View attachment 244234 View attachment 244235 View attachment 244236 View attachment 244237
Let the community know what size tires you replace the Bridgestones with. Be interesting to know if the ones you have currently are not rubbing because of tread wear.

I shall. Still on the trial tires and no rubbing yet after two weeks day to day driving.

I need to pull the trigger on new tires. Having doubts on this size and considering a 285 50 20.

Can you run a 285 tire on Pikes Peak 20" wheels? Is the rim wide enough?

There will be photos of the finished product.

285/50R20 will fit a 9" rim but the tires will rub your fender liners (there was a post on page 17 about this. If you are planning on doing any off road and will encounter rocks, the profile of tires in the 20" rim size will not afford much protection for your rims as the sidewall is very small. My Touareg came with 20" wheels but I am downsizing to 18" with a 265/60R18 which another poster utilized with great success, no rubbing and plenty of sidewall to protect the rims. I am going with the Toyo Open Country in that size as they are considerably lighter (37lbs) than the competition. Considering the UN-sprung weight (lower the better) of a wheel and tire combination will add to your performance. Larger tires may look appealing, but there are serious downsides to the added weight...

Not planning any serious off-road. May travel some back roads and old logging roads. Will not be rock crawling.

May need to rethink the 285 50 20 based on the the rubbing comment. Further investigation is required; however, I note wheel offset on @rrealm20 setup had a 35 mm offset vs the stock Pike Peak 57mm offset. This along with the 285 width would have the wheel sticking out 27 mm further than my current set-up or the stock 20". That is over an inch. There is not that much horizontal room. I suspect the rubbing issue had more to do with the material offset difference.

275 55 20 vs 285 50 20 = 0.7" less diameter and 0.35" less vertical within the fender liner. The 285 width will be 10 mm wider (5 mm inside and 5 mm outside). They shouldn't rub.

More investigation.

Anyone on 285 50 20?

@JCstomper : I recollect you had some pre-lift rubbing. Do you think that was simply the tire size, or that size in a an AT tire? How bad was the rubbing? I see you were selling the ATs. Did you move to another size? If so why the move?

The rubbing was very minimal and only at almost full lock. There was a sweet spot where the outer edge kissed the liner. It was probably the AT tire more so and not the size..

I kept the same size tire now but took off the AT's more so because of noise. They got annoying to be completely frank.

UPDATE 275 55 20 on 2011 TDI Execuline

I had my used test set for a 3 week test drive. No rubbing on the fender liner, so I bought a set of Motomaster Total Terrain APX (Canadian Tire house brand manufactured by Cooper USA). These are similar style to a Cooper Discover HT.

My independent mechanic phoned mid install. He was paying attention. Hey noted that the clearance between the upper ball joint stud and the tire was paper thin. He checked the old tires and no scrapes but you can see a line that looks like polish. He said when the tire flexs the sidewall, it would rub ever so lightly. He recommended we go back to stock. Five minutes later, he calls back and said the BJ stud is long enough thaty he can grind a few mm off. He was comfortable with that solution, so I said go.

Long story is a 275 55 20 will not fit without modification, albeit slight. Still does not appear to be rubbing the liner. (TDI with inter-cooler vent)

Looks very sharp. I will post pics in the next few days.

I'm starting to look into AT tyre's for the 20" wheel, considering stepping up to a 285/50/20 from the current 275/45/20. I must mention we do 90% city driving, but do intend to start getting away more with light off road / unsealed roads. I wouldn't expect to be doing anything to extreme.

Mainly after a little more wall height and protection, and to also stay within legal limits. We are limited to a 50mm diameter increase.

Can I expect much of a ride quality increase stepping up to the 285/50 or is this small increase not even worth pursuing?

Nitto Terra grappler g2
Falken wildpeak atw3
Coopers zeon ltz

Or perhaps something like Bridgestone dueler H/P would do since we mainly do city driving.

Understand any AT tyres are going to have an increase in road noise, but would prefer to keep that to a minimum too.

Any suggestions for a pick out of those tyres?

Your ride quality will change for sure. It more of a truck like ride, particularily the manner in which it absorbs bumps in the road. On the negative side, the vehicle's cornering is more truck like in terms of body roll.

I ended up with the Falken AT3W tires and agree with an earlier poster that the additional noise generated is unacceptable. This is going to be the case with any AT tire brand so if you are mainly driving on normal roads you will probably be better off with a good all season tire. If you must have the "look" afforded by the AT tires then go for it but for me that aspect wore off quite quickly...

^^^ You sure about that tire size?

Good catch: Correction on the size: 275/55/20 Bought new tires for my Z4 this week so the 245 must have stuck in my head. If you follow the thread back , you will not discussions on this. It is very tight at the front with the wheels turned 50%, but no rub.

I had trialed a used set in this size first. The upper ball joint stud is an issue when the tire flex it will touch enough to but a sheen on the tire. My guy cut 1/4" off the stud as there was room to spare and no issue.

Check out @ncburch22 on this thread. He also ran 275/55/20
