He said the spacers would throw off the inputs form the wheels and the computer would be getting the wrong info. The amazing thing is this tire place is not a conservative place. It is the kind of place that sells 24 inch wheels!

Have you, or anyone else for that matter, heard anything like this? I had spacers on a 2001 Porsche C4 that were dealer installed so obviously that can't be bad in every situation.
