I've had them realigned by Seat and they still seem to be wearing on the front. Apparently, the last time it was realigned (about 1-2mths ago) it was seriously out and they spent about a day trying to get it put right. I do quite alot of milage (about 2-3k per month) but it's mostly on motorways so I'm a bit miffed really why hey would be out so quickly. Any idea what the average life span is on rubber for an R?
