I stand somewhat corrected: haven't ordered tires for past three yrs and that
was what I recalled for road tires. Looked in several catalogs and web sites and there are not as many dual wire/kevlar beads as there were, or they are
not listed, typical price differentials are $12, with Conti 2000 Ultra having a
$9 difference in price. Wire bead tires seem to be ~100gr heavier than kevlar
bead equivalents. You seem to be stuck with the limited # of suppliers for your desired tire. I have been looking at Schwalbe Stelvios for my bent, the only
406 size with kevlar bead/belt, and the price difference wire to kevlar bead is
about $15-18 (28 -> 42-5). It takes about 20min to wrestle wire beads on the bent rims. Steve
