That REALLY is not a very smart idea! Its like waving a red flag at a bull!
Like the other guys have said, as soon as they spot the over-sized wheels on the car, it is an invite to go all through the vehicle, and you have the potential to have all sorts of things defected... including not having enough water in you windscreen wiper reseviour.
Could become bullshit expensive, and time consuming, and for what? having some Mexican poke?
