I recently replaced the tyres on my van. After "shopping around" I found kwik-Fit to be as cheap as anywhere. I booked their mobile fitting service who came to the storage site and fitted the tyres (with Tyron bands)in around 20 minutes........well impressed !
I had a couple from Camskill's for my van, but TBH, with carriage and the cost of a tyre fitter to fit them, there wasn't a lot in it. Do get 'C' rated (commercial) ones though.
