New Rubber Needed for the Treg; Help !

[barefoot]

Barefoot, what size are you running with?

stock size 255/60R17

[dmm_au]

I did a little research here for the 17" wheels on the TDv6;
VW support to sizes.

http://forums.vwvortex.com/zerothread?id=294473

235/65-17 29.0"
255/60-17 29.0"

The first is the size used in the offroad package. Because both tires have the same diameter the speedo will be correct. As I've ordered the tyre carrier, I'm also concerned about choosing a large tyre that might work on the car, but not fit the carrier.

This is a little list of tires that seem popular. %slow means you speedo will be out by this amount. Frankly after the good recomendations in this and the clubtouareg forum, I don't think I'll go past the first entry.

''Cooper Discoverer ATR 235/65R17 104T (739mm) 0.1% too slow''
Toyo Opat 235/65R17 104H
Dunlop Grandtrek ST8000 17 255/60 106H (737.8mm)*
Cooper Discoverer ATR 245/65R17 107S (753mm) 1.7% too slow
Michelin Pilot LTX 17 245/65 105H
Mickey Thompson ATZ LT245/70R17 119R (777mm)
Cooper STT 245/70R17 119Q (780mm) Very Aggressive 5% too slow

But please jump in with opinons. I'd be especially interested if anyone has a rear tyre carrier with larger wheels.

Rubber and Front end alignment

Having just sold my Cayenne to buy a Treg I have learnt 2 things--the front end needs to be realigned as they are all factory set to understeer and wear out the inside of the tyres..Donnellans at Box Hill have the correct settings..also Bridgestone 680 tyres were excellent on the road and have now been replaced by683 ?Rgds

Interesting. What have you noticed about the difference between the two cars?

There has been quite a lot of discussion about tyre alignment and premature tyre wear on the forums. Did you get some form of report from Donnellans Box Hill showing how much they changed the alignment.

Personally I was after tyres that would increase the Touareg's performance off road, but thanks for the road tyre tip. I've ordered a vehicle and I assuming it's going to show up with Wrangler tyres. Have to wait and see.

Alignment

Ring Mark Donellan at Box Hill-he has the specs in his head...680/683 tyres are about 25/75 offroad and killed the standard road tyres--Rgds

I'd guess you're refering to the Bridgestone All Terrain (AT) tyre.
Looks good, but the sizing isn't perfect. 9mm larger.
I can see some exact matches in the HP Dueler, but for the D683 Highway Luxury, I can't see a good tyre for the 17" rims.

Dueler A/T D694
Bridgestone D694 (225/70R17) 225 70 17 108 S 747 RBT

Dueler HP Sport
Bridgestone Dueler HP Sport (235/65R17) 235 65 17 108 V 738 TL

I came accross a Mud Tyre from Goodyear.
Personally I think an ATR would be more appropriate than a MTR for me, but a common complaint seems to be a lack of off road rubber for the Treg.

Wrangeler MTR 235/65R17 104T available

http://www.goodyear.com.au/TyreDetailAction.do?website=GYR&mtpcode=00071&from=nPerPage

Which doesn't have a high enough load rating. For the 255/60/17 it's 106, and the 235/65/17 it's 108!

Has anyone had any more success sourcing an adequate off-road tyre ?

I'd like to cross the Simpson, from Bridsville, then the Tanami, through the Kimberly and then back down to Perth. I am amazed at the difficulty in finding not only suitable tyres, but even information on suitable rim/tyre combinations for the V6 TDI.
I never had these problems with my 100 Series L/C's, on which all ran either BFG AT's or Coopers.
I saw some images on Club Touareg of a V6 TDI with 265/70/17's, .....looked great, and would no doubt do the job,....but has anyone got any real idea of what the likely impact of such a tyre would be on the drive train, the steering, and the trip computer ? ..... would it be seriously detrimental (damaging) or would it just be inconvenient until one returned to normal/standard size rims/tyres ?
Any advice from anyone in the know would be gretaly appreciated.

Hi bobt,
Welcome to VWWatercooled and (if your treg is new) congratulations on buying this awesome machine.
To help answer your questions, we all share your frustration about lack of information and lack of easy-to-get stuff for the T in this country...
As far as the drivetrain is concerned, I don't think that you can do it much harm with minor mods to your V6. It has been built to handle the mighty V10 and even the W12.
The fitting of slightly larger tyres will of course affect the rolling circumference of your wheels, and so the speedo / odometer. All VW speedos read high by design (VW policy to avoid speeding tickets) but the odometer and trip computer functions are accurate with the standard tyres. Use something like the tyre size calculator http://www.miata.net/garage/tirecalc.html
to check the likely effect of any change you think of. For stock size of 255/60 (VW website) The size you have quoted would give a circumference increase of 8.8%. This will result in a slightly taller gearing, and will fix your speedo error, but your odometer and trip computer will gain this error. Coopers and BFGs are run by various members here and on Club Touareg and seem OK. Make sure you get a speed rating well in excess of your maximum driving speed. You are unlikely to be able to buy an off-road tyre with a speed rating up to the originals.

Cheers,

..Neil

I'm booked in to get some Pirelli Scorpion AT's 235/65/17 on Saturday.
They are slightly thinner than the stock tyre, but supported by VW on the same 17 inch rim.

The Pirelli's score better than the Coopers in this review.

I'll provide feedback when I've done some driving on them.

Hi - If you don't mind me asking - what price did you get these for? how are they going - I know it's early days yet...but I am going to have to ditch the Dunlops pretty soon

[dmm_au]

The best price I got was $330 per tyre. I belive the margin on tyres is probably 50%, so I expect I could have done better, if not for the requirement to trade in my Pirelli Rossos at a good price as part of the deal (I got $200 a wheel).

So far, I'm very happy with my purchase decision.
Drove to the Toolangi state forrest and went down some fire tracks.
Drove down windy mountain roads in light rain.

Excellent traction, and perhaps a little more road noise, but I find the Touareg's cabin well insulated.

I wasn't game to try them in the mud, as I was alone, and didn't have anyone to snatch me out if it went badly. The reviews say they are good, and the on-road trade off seems minimal.

I like that they meet the VW spec as shown on the placard, which makes me feel better if I do need to make a warranty claim.

Note I got the Pirelli Scorpion AT, not ATR. The ATRs claim to be better onroad, but the ATs were the ones I had seen reviewed and were available.
I may end up with ATRs eventually as Pirelli are to replace the ATs.

Thanks for the prompt Reply

Looks like they'll do the trick then... Just need to start saving up

cheers again

Hey guys, I hope all is well over in Vortex land; seems like clubtourage is dead this time, its been down for days, a real shame to see all of that information and data go down the tube.......

After only 25,000km I need new tyres. The stock rubbers (total rubbish) are near slicks and I think I want to buy Coopers. I know there was a lot of stuff about Tyres on CTreg, but with it gone I cant search. I have an R5 TDI 2005 model running the stock rims. My question is what model and size Cooper should I be looking at. Majority of driving (90%) will be on city roads.

Any comments on Coopers ? Pro's/Con's ?

As a side line, the VW Dealer told me that that a regular Tyre fitter cant do an alignment on a Touareg (I can hear you laughing), I should have the dealer do the alignment, my assumption is anyone who sells Coopers knows 4WD's and shouldnt have any issues;any comments ?

Im also curious what I should be paying for these (I live in metro Melbourne).

Any advice would be much appreciated

Dave (oznino)

Have you checked out the Pirelli Scorpion ATR's? No fit on 19's..but they report in the US SUV tyre surveys as No1. They seem to fit 17" and 18" OEM. I'm looking for a set of OEM 17" / 18" so I can get on the dirt.

[dmm_au]

I've just got back from a 1000+ round trip through the Grampians.
The new Pirelli Scorpions (AT not ATR) went very well on both the highway and the dirt and rock tracks.

The track report proved valuable. When they say a track is good, it really is.
I'd recommend the Grampians to any T'regers wanting to get of road, but not wanting to damage their new vehicle.

Still haven't tackled mud.
