At first I did it wrong and thought the tyres were too big. I tried my spares first. These were donated by eastie.
This video helped with fixing up the tyre's and tubes on Mountain Bike Maintenance : Install a Bicycle Tire
I did however manage to get tyres from my LBS too for $60 both.
I don't have bolts for the rotors, so will have to pay my LBS a visit tomorrow or on Wednesday to get the bolts.
Hopefully I can ride by Wednesday .
