Thanks for your reply Gareth...

in answer to your questions the existing 260/30/20 on the car are load rating 95, speed rating Y and the are XL. 
 

if the 265/35/20 will increase the tyre height too much how about going with a 275/30/20? There seems to be much more choice. 
From what I can make out the 265/30/20 are what the car was originally sent out of the factory with

regards Ollie 

I have a 2009 A5 cab 3.0lt Quattro and need some new tyres. Having looked around the 265/30/20 are very expensive and limited in choice. Has anyone changed their tyres to a different profile...( I’m looking at the 265/35/20) and if so have you had any issues? 

The 265/30s are quite a hard ride and my fronts have both suffered from side wall bulges

thanks in advance for your input
