I've been a few times now, for tyres and balancing. You can have a wait at times, I think the longest was upto 2hrs for 2 tyres to be changed, but they were very busy. Normally it's much quicker. I never get the impression they're trying to create work, in fact I've had them tell me not to bother spending extra money. They're also willing to explain things, especially to those of us that don't know about cars.
I would give five stars but I haven't been lots and lots, but it's certainly the first place I'd go to for tyres. I've even found out friends of mine go there and really rate them.
Price wise they're as good as anybody in the area.
