Well, more like 6000 each. The first one I changed a bit early, because I was about to head out on a 4000 mile trip, and it had maybe 1000 miles left. I literally only just put the third rear on. But I do go through tyres pretty fast.
I'm at about 11700 miles now, so next week I'm doing the shim check for sure. I don't know what's involved balancing the throttle bodies, (haven't looked it up yet), but if it can be done using a vacuum gauge and screwdriver then I'll be doing that myself as well. I'd hate to have to take it to a dealer, but fuel injenction is new to me, so we'll see what's involved.
Before he did it, I'd have said it couldn't be done.
