Q7 Wheel Alignment

[andy241278]

I have a 57 plate Q7 with the 21" wheel upgrade, it is scrubbing the tyres on the outer edge and i have taken it to Lincoln Audi who are unable to offer me a wheel alignment due to their alignment machine only been able to align wheels upto 20". Has anyone had the same issue and does anyone know of an Audi dealer with a alignment machine that can take the 21" wheels. I am over the mileage for goodwill from Audi for tyres but the Dunlops are now £340 each so want to get it checked before i replace them in the next month.

Audi dealers using biesbarth equipment can carry this out
Also ask about the software update for the air suspension settings to reduce tyre wear.
The sw update reduces the vehicle speed at which the suspension drops to dynamic mode.
Also increase the tyre pressures to maximum and this also will increase service life of the tyres and check them weekly
