install new tire and tube

All right folks, Last time I tried it, I ruined 3 tubes before I took it somewhere. I used tire spoons and tried to be ever so careful but put a small punture in all 3. What's the trick? It can't be that hard. Thanks, Doug

Ouch! I hate it when that happens.

I guess the only trick is to be very mindful of where the tube is. Constantly pushing it back up into the tire so it doesn't get pinched. Also, inserting the tire iron the bare minimum to get the job done - not jamming it way up in there and wrenching the tire onto the rim.

Another nice trick is to wipe the tire bead and the rim with a bit of dishwashing liquid soap on a sponge. This helps the tire to slip onto the rim. Less force needed = less manhandling required = less chance of pinching the tube. Inside of tire bead and outside of rim for the initial install; outsite of tire bead and inside of rim for inflating & getting the tire centered on the rim.

Another trick is to kneel on the tire bead that's already installed as you work your way around. The idea is to get the tire bead to drop into the 'dropped center' section of the rim. This gives the tire a bit of room to shift towards the side that's not in yet. Again, just a little way to make less force be needed.

Good luck!

Put some air into the tube before doing the second side of the tire.
Just enough to plump it and take out the wrinkles.

I use a rubber mallet to install tires after the first pry of the tire irons, seat the bead as tight as possible with your knees pry once and get the rest of it with mallet hitting the bead right above the rim .... piece of cake

Yamaha has a great aerosol bead lubricant...but mess makers like me use too much and its hard to get off places where it then gathers gunk to it. Miraculous easing of the task of getting second bead over the rim though.Then there is the plastic garbage bag technique that some-one posted recently

Ordered the tire and tube today. Thanks to all who answered with great tips. I knew it couldn't be as tough (and expensive) as I was making it. Will read this again when the tire arrives. Doug

PS: Last one I had done was a Ca95 tire and tube. They charged me $28 bucks I think it was. I thought that ridiculous so was bound and determined to do it myself!

The rubber mallet technique works brilliantly.If you, like me, tend to be leaning more to getting the job done than worrying about the odd scratch, then standing on the tyre using heavy boots to hold the bead down in the well of the rim while you work the mallet works well.Takes some experimentation to work out where on the rubber coated bead to hit , and at what angle, but it sure works.

IF you use levers then having longer tyre levers can transform the degree of effort needed too...working out how to use a third lever also helps.

I coat the new tube with baby powder before placing it into the tire. Inflate enough to smooth it out then let it relax again. I also use WD40 on the bead to make the tire go back on with the spoons easly then inflate to seat the beads. WD40 evaporates after awhile so no risk of tire rotating on the rim later.
Wipe off excess WD after inflating tire before you balance.

I used the trick where you place a plastic garbage bag over the rim then press the tire over the rim. It can then be pulled out after it is installed. It worked better on one wheel vs the other but with practice should work well. i do like the mallet approach also.

Here is a video many have seen probably that member 'jeepurz' posted awhile back about the bag/rim trick.
