After six months of ownership in Colorado and purchasing a loaded V8 Treg for it's alleged off-road ability, besides numerous defects such as the TPMS, Gear Workshop warnings, seats, Air suspension, lumbar and other electronic breakdowns...I'm completely frustrated :chainsaw: by the fact that you can't purchase legit. off-road tires such as a BFG All-Terrain. I recently pinch flatted a tire for the third time hitting a curb turning around! Twice before on trail the tires flatted on mild rocks, even air-down at at low speed. I'm a very experienced off-road driver, having taken training courses with Bill Burke's 4wd America, and participated in off-road seminars and clubs for the past ten years. It's obvious the Germans no nothing about true off-road driving or they'd have offered a 16 inch wheel with the ability to put a larger sidewall. Those considering larger wheels such as 20s should be well advised that their Treg's limited off-road capability will be severely compromise. Tires and Wheels are the weak link to this vehicle!

I have a testing video showing a Touareg hitting a curb head on at about 50 mph. No blown tires. You must be hitting the curb at too sharp an angle to allow for even contact across the tire patch.

Yeah, I was doing a three point turn in my neighborhood at a pretty slow speed. Guess it was the angle or the fact that the Nitto Terra Grapplers have an incredibly weak sidewall. Just wish I could find a way to put a larger tire, preferably a BFG. :confused2:

Somebody here mounted some larger tires on 17" wheels. They might have been Bridgestone Dueler A/T Revo, 265/65-17.

16" wheels won't fit on any US spec Touareg - the brake disks are too big. 17"s will work though. Tire manufacturers need to catch up and offer good tires to fit.

And I would rather have big brakes than big, noisey tires.

I have a set of 265/70R17 BFG AT I plan to trial fit to my wifes Treg... hopefully later this week, if the 17's arrive. The'll be tight, maybe require some minor clearancing, but at least it will be known.

Using the below link to figure out the diameter, the width is ok, but the total diameter will be 31.60". Science Geek put on Bridgestone Dueler AT Revos 265/65/17 and his diameter was 30.56" and his post indicates about 3/4" clearance at the back wheel well and 1" at the front. So you might be rubbing with those size tires.

In theory, the BFG's should sneak in there. Being 1" larger, and having .75" of clearance remaining on the next size down...

The wheels I have on the way are 8.5" wide w/ a 35mm offset, that may cause some issues???? Minor rubbing of the liner is really not a huge deal to me, plastic is easy to "clearance. We'll be running 33" tires before you know it!

He could use smaller air molecules. :crazy:

Larger Diameter Tire question?

I asked dealer and VWOA what maximum tire diameter could go with as the all the stock tires are approx 29" diameter. I was concerend with the spare matching.

Answer got back from dealer was would have issues with the ABS brakes and other traction control stuff if I increase tire diameter. Would seem like some tolerance has to be built inot the system. Never got answer back from VWOA!!

Anyone else have any ideas on this issue?

Will larger tires cause problem with the electronic systems??

I also have the REVOs 265/65/17. No ABS issues what so ever.

 

[MountainLord]

Is it possible to switch the 18 inch wheels on the V8 for 17 inch or do they interfere with the brakes? I can't remember, but I think that's why I had to go the the Nitto Terra Flatters at 255/55/18s.

 

[spockcat]

17" wheels will work on a V8 or V6, not on a V10.

BT,

Your service person is full of horse-hockey!!!

ABS and all of the traction/stability control systems are based on sensors on the wheels and I believe there are sensors to detect "yaw" as well.

So, regardless of your tires, the sensors read slippage and traction --- and that has no bearing on tire size.

Some of these VW people just don't know what the hell they're talking about.

I believe they read slippage by rotational speed. Changing the diameter of the tire changes the rotational speed that the computer is programmed to know. So, yes, changing the diameter of the tire will screw-up some of the systems, if they are programmed in that way.

Why not? I thought in the U.S. all three vehicles had the same brake components.

Not true. The V10 has 350mm brake rotors up front. The V6 and V8 has 330mm brake rotors up front. The V10 cannot use 17" wheels. The R5 has 308mm brake rotors.

I now carry a full size spare in the rear comparment due to two flats from rock cuts in 8000k miles.
