I've been fitting tyres to my trail bikes for years, but never a road bike. So I thought; "How hard can it be!" I picked up a pair of T30s for £175 which I didn't think was a bad price. (Dated Oct 2017). My local mechanic had always supplied and fitted my tyres, but for a pair of T30s he wanted £235 - fitted. Usually I'm ok with a £20 difference, even £30, but for £60 - I'll give it go

Of course I have most of the kit I needed except for a mount/demount bar for alloy wheels. I picked one up for £70, all nylon coated stainless steel. And a wheel balancer + weights
I bought an alloy wheel to practice on off ebay for £10 (from a 1995 ZXR400). I changed that tyre about 10 times. I made a note of things that worked well and what didn't. I can't say there wasn't some trepidation when brought the XR rear wheel into the garage and put it on the (manual) tyre changer:
The hardest part was breaking the bead!

Putting the new tyres on was also reasonably easy despite some hefty pushing and shoving of the bead into the drop centre, aided by a large cable tie.
Things nearly came to an abrupt halt when my small-ish compressor only just about delivered enough air to pop the bead on the rim of the rear wheel, but it got there with a very pleasing POP-POP.
All completed without issue.

I found manually balancing the wheels strangely satisfying!
Scrubbed in the tyres and no issues as far as I can tell. If you don't hear from me again there was a problem.........
