Tire is a Kenda Kriterium
Rim is a Ritchey 28S Pro
Lost a tire to chip seal mid way into an 80 miler. I discovered it was nigh close to impossible to get the old tire (Kenda Kaliente) off.
Never was able to get the new tire on.
Literly straightened out a set of Spion Doctor tire levers (the ones with the alloy reinforcement in them)
Got home and tried 10 min in the dryer ..
Tried a new set of levers
Tried pig snot (even tho these are kevlar bead tires)
The tire simply will not stretch that last 5" to snap over the rim.
The tires fit on the Mavic CXP23 rims fine..with just thumb pressure to push the bead over the rim lip.
Are all these aero rims this much of a ***** (the CXP is midway between aero and std)
Suggestions??
Thanks in advance

My Kinlin rims are hard to mount, too. I had mangled levers and sore fingers the first time I tried it. I thought I would need to carry steel levers on a ride. I even need a lever to mount the first bead, and there's no tube on the wheel. That's tight.

Now this is how I easily mount a new tire. The trick is to just lift an inch or less of the bead at a time, slide the lever over, and repeat. It's fast and easy.





I use these Continental levers that have a rounded tip to help avoid pinching the tube, and a flat back side to let the tire bead slide down to the end of the lever. Pedro levers have a similar shape.




There's a lot more pictures and commentary in my old thread on mounting tight tires.

Make sure the rest of the bead is in the centre of the rim so it frees up slack, make sure the tube is deflated after you have fitted up to the hard bit. Use a bit of dish soap as a lubricant. The rim/tyre combination I had were so tight I snapped a spoon in it but using the above methods I can get it on with no levers at all, Strictly levers shouldn't be used to put tires back on. Although I know the below rim will not be the same as yours I am just using it to show that the tire bead should be in the centre for 'maximum slack' (that phrase sounds silly)

Just ordered a set of the Pedro Levers. THe Spin Drs -while extremely sturdy may have too thick a lip to get under the darn bead.
Going with the plastic Parks I got in the starter tool kit Bicycling magazine sent me I gave it a shot following rm-rf s pictures I get just about that far and simply cannot hold one side or the other while inching the tire over the rim. It begins to slip off the trailing end as the tire lever lifts the leading edge onto the rim.
My main concern is finding a way to get tires on these rims (they seem darn narrow)while out on the road
I'm thinking a trip to the LBS is in order..not to have them put em on but to get a hands on on how they do it.

When tires are hard to install/remove, I look at the rim design and the thickness of the rim strip. Replacing the rim is tough, but a thinner rim strip does wonders. Try the thin nylon stuff, like these:

Try Kool Stop Tire Bead Jack. This should do the trick.

Kool Stop Tire Jack
Ran my problem by members of the one club I belong to on a ride yesterday and didn't one of them have this handy little device.
Going to give it a go this morning (64 miles, two long climbs and a family picnic yesterday left me with no energy to do much once I got home)
Discovered that; Niagara Cycle (which is literly in my back yard) carries these!
Will let you all know how this worked.

Kool Stop Tire Jack worked!
It took a lot of 'popeye thumb' pressure but the tires popped on with this device.
I went back and picked up a second one ($12.95)after getting the back on and using two (have to figure out how to carry em on a ride) made the entire process a 'snap'
What I'm going to do is remove and reinstall the tires several times which will hopefully add some stretch and make removal/installing easier out on the road.
Thanks to everyone for the advice

Lubing the tire beads and the tube with talc can make significantly easier to get on and off.

Don't quite understand why you need two of these devices on one install. What is "popeye thumb"? The tire bead jack should work without any thumb pressure. The unique leverage setup does the work.

For bike rides, I use a larger bag to carry more stuff. The tire bead jack will fit. Some day you will help a poor bloke out with this device while on a ride.
