I am not a big fan of the standard alloys that come on the TD6 RR Vogues. Any idea where I can get hold of a 2nd hand set of something else, or in fact swap mine for something else? Thanks.

Hi I am new to this forum so be gentle. I have recently purchased a 40,000 mile 3.0l Vogue. I have heard you can chip them to help the fuel economy which pretty much sits at 20-21mpg. Occasionally it gets to 22 on a long trip. Any pointers? TIA
