Hi Jowan, need abit more info re removing wheels ,how about a couple of pictures ? Also re Kiwi's post by half on He means one side of the new tyre on . Before you do put it on check the rim tape in fact as already said by Tomcat don't mess around new tyres equal new tubes and a new rim tape ,you've only one neck ! after all .With the rim tape removed check for any spokes protruding etc.
back to fitting 'em, in place of silicone which I'm sure is great you could use washing up liquid ,messy but helps thing slide , keep the tyre well into the "well" of the rim ,tread the tyre round as far as you can (kiwi's heavy boots ) with abit of luck you'll only need to use tyre levers for about the last 12 inches ,( not screw drivers ) check the levers don't have any sharp edges by the way ,don't push the levers in too far to avoid the tube ,take small bits at a time and don't use brute force ,keep walking the tyre round with your knees and it all should slip into place. once done inflate and check the beadline ,it should run equidistant to the rim all the way round ,if it's higher one side let out the air, whole wheel round to offending high point is at the bottom and bounce refill with air and if required repeat . When happy check for leaks with a bowl of water and if all well, go and get a few
and breath !! then repeat with other tyre , best of luck
