I'm going to express gratitude to Keef, again, for the suggestion of hair conditioner to lubricate the bead of tyres going on. I used to use dish washing liquid. No more. I swapped the tyres on the XT & TTR the other day. They slipped on really well. Still not a favourite task but, if there is a tip that actually works, all the better. The even seated on the bead around 20psi. No huge 'bang' like when it finally lets go at 70psi. If they hadn't seated immediately, they just slowly slipped on with a bit of low pressure. Cheers Keef. Been out on your bike yet? Or still a couple of days to go?
