well i have to say i have used wire bead victiorria zaffiro tyres on khamsin rims

and managed to get them on sans tyre levers no problems

they're not light but great training tyres put almost 2000 miles on them so far with very few punctures and they inflat to 145psi and wear really well(with rotaion).

although today i sliped on my good wheels with michelin pro tyres and noticed a much smoother ride. maybe its down to the 116psi inflation.
