Hi
I've just bought a set of Hoop SP-AM4's (Por 3 hubs with DT Swiss EX5.1d rims) and I've had one helluva issue with tyres! I moved across my old Maxxis Advantage 2.1's and I went through 3 tyre leavers (2 were off a multitool and one was a big fat plastic one) to get them on.
In the eventuality that I'll have to take them off at some point for punctures/replacing, would switching to kevlar beaded/foldable tyres help? The neighbours are complaining about the swearing, so any help would be appreciated!!!

The woes of tight fitting tyres. Have heard of others having this problem. Solution? Try these.

Schwalbe folding tyres do have a generous fit, so you might like to try them.
Remember this though... if you run at a low pressure, a loose fitting tyre can work its way off the rim...
.... so a little struggling with the right tools will pay off!!
Just try doing the job with a mouthful of toffees next time - saves the neighbours' ears!

Hi
Had the same problem myself swapping to some Schwalbe's. Could i get 'em on, could i bo77ocks. Took them into work and one of the lads put them on with no levers. Just a knack of making sure the beads are in the deepest part of the rim and a bit of washing up liquid.

It's them dt swiss rims i think. I have the same ( 4.2 though ), good though they are, they are bl00dy tight. I also have a set of tubeless ready tyres which are also a bit snug on my other bike, i must say when i put the two together i'm surprised you ALL can't hear me swearing. My summer tyres are racing ralphs, and i can't really say they are much looser than any other make of tyres.

I have had the same problem but recently made sure that when putting the tyre on, start at valve end and work way around with thumbs until opposite valve goes in snug...taking off, start opposite the valve. Sorry if you know all this, but I have just put new tyres on DT Swiss Rims and definitely easier this way.

I have had ome pretty tight fitting tyres in the past but i still don;t know how people manage to break the plastic one. The ony thing I can think of is that people hold them right at teh far end of the lever from teh tyre. You need to hold the lever right up close. thhe park ones have a nive groove for thumb and finger on the, as a guide.. they seem bomb proof to me... Don'tknow if it's technique or shoddy tools used by others or that I've never encountered my nemesis in tyre form yet but I never seemd to have the issue.... well so far anyway

Same rims EX5.1d's it may be the rubber as I have been pulling mine off and on with my hands today, and they are a bit knackered (my hands that is!) 
The above advice is correct, the try pushing the rubber with both hand down past the edge of the rim into the center where the spokes are first, then starting at the top grab the rubber and push down, work your way down the loose bit should now be at the bottom, grab the tyre there and pull at least one side of the rim, if thsis works no need for levers, no nicked inners to fix.

Does this also work at the top of a large hill, say in Northumberland, maybe Kielder for example?

You know it does!
Only once could I not get a tyre off doing this on a frends bike, it's got to be combination of both tyre and rim, have used my current Tyres on Mavic 223, 321 & 729, DT Swiss 420sl and the 5.1's.
"Folding type" must help, as steel beaded won't compress and flex.

Just noticed that they are the tyre levers i have now, and they work really well. All the others i have used bent at the tips trying to get the tyres on or off.

This is a known issue with some D.T. rims and even more so with the 5.1. I wouldnt worry too much because they appear to be made of the softest alloy known to man and you'll probably egg them and be replacing them before long. FWIW ive never had this problem with Mavic...
