An interesting choice to make.
SO, my grail bike arrived with ancient Specialized Turbo R (slicks) tires. Iíve done a shakedown ride with them, but I just donít think they can be trusted. The sidewalls are quite dry. I tried a coating of tent seam sealant, as suggested in another thread. Meh. I don't think pinching that penny is especially worth it. Here is photo with and w/o a dose of the sealer.
Plus the slick tread has a fair bit of cracking. SO, I think I should sacrifice these into the bin.
Replacement choices, oddly enough, are from the same Specialized folding Turbo series. I have two mismatched pair.
Pair one is 25mm. One is very nice Turbo S. I bought this new, probably in the very early 90s. The mate is a Turbo SK4 that has a thin Kevlar belt as well as bead. Iíd probably put the Kevlar on the rear.
But, which way does the tread orient?
The label is printed on one side on one tire, the other side on the mate. That is if Iím reading the tread correctly?
The other pair is 28mm. Because I have another wheelset of low-flange campy, VO PBP rims and 23mm Vittoria Corsa tires, Iím leaning towards mounting up the 28mm first.
The mismatch here is an original 28mm Turbo and a Turbo/S, although clearly a later product from the 25mm Turbo/S. The tread here is thicker. Iím thinking this goes on the rear.
Oddly, this mismatched pair also present the curious labeling w/re: to the tread direction.
I see an outer pattern on each side that form an > shape.
Am I right to think it is pointing in the direction the tire should turn?
Open to suggestions.
