Tyre rotation.

The only reason you wouldn't be able to change diagonally is if the tyres are designed to rotate one way, you can still change front to back though in that case. so yes it's a load of old B****cks!!

I'm sure I've heard in the past that this IS a problem with 4wd's......causes wind up in the transmission system due to uneven stresses......???

Dunno any more than that sorry but might be worth investigating a bit more....

VW recommend that there is no more than 2mm difference between front and back tyres to prevent transmission wind up. This is our fifth 4x4 of various sorts and can't say I've has a problem with difference in rolling radius etc etc.

AND, on every other roundabout, you should navigate anti-clockwise. this evens out the difference in the distance the left and right wheels have to travel, :roll:

....yeah...yeah.....but dont forget about VW's track record with the transmission system....don't want to provoke any faults that coudl be avoided/give VW reasons to wriggle out of a claim.....

I guess if I were telemetrically superb it wouldn't be a problem

I had the tyres rotated on my last set (whilst the car was in for new wheels under warranty) and my new set of tyres look like they need rotating after only 6000 miles. :shock:

I checked first in the owners manual and it recomends rotating front-to-back keeping the tyres on the same side of the car.

For me this looks like the best option as well as the Front Near-side and Rear Off-side seem to be wearing most- so swapping with the one on the same side should even things out for a while.

On previous audi A6 & A3 quattros we were told to change all 4 tyres at the same time. On the treg I've rotated the tyres from back to front, but interestingly talking to a tyre fitter recently he recommended keeping your good tyres always on the back??. To be telemetrically superb you have to go straight across the centre of roundabouts, that's what these SUVs are designed for.

....well thats just not right......

:wink:

Good info though!

What tyre pressures are people running? I am running when cold 45-46 back and 43-44 front, now have travelled nearly 8,000 miles and all seems to be going ok, however I had the pressure a little low by accident (42-43 back and 41-42 front) for about a 1,000 miles and could really notice "scrubbing" on the outer sides of the tyres. I am still running on the OEM Pirelli's 255 60 R17.

Those pressures seem a bit high. Recommended for 255/55-18 is 38 psi at the front and 42 at the rear. There should be a sticker on the back edge of the drivers door with the tyre pressures on it.....I know some people have mentioned running slightly higher pressures, I'm sure there is a thread on the forum somewhere......

I run my tyres as if the car was fully loaded all the time, even though it's normaly only got me in it.

Tyre wear over 20K on Hankooks is excellent, still have 6mm tread depth left and even across the whole tyre and no difference between front and back tyre wear.
