I recently discovered that the XT is overdue for its bianual T?V exam, which should've been done in Febuary already. Ooops.
Anyway, both tires are pretty close to or already at the wear limit. They're Metzeler Tourances and were already on the bike when I bought it, and since I didn't find anything wrong with them I'd just go for them again. So I looked around the net, found a tire discount chain that even has a location nearby where the set'd be around 130?, with 10? for fitting the tires per wheel.
If you bring the unmounted wheel, they won't touch the bike itself.
Since I don't have a jack to prop the bike up with both wheels off I went to a nearby mechanic, who wanted
220? for the same tires+fitting. Uhmm... no thanks. For that kind of money I could just buy a hydraulic jack
like this and take the dismounted wheels to the other place, leaving me with a tool I'll be able to reuse. So that's what I'll do, I guess.
