The major selling point of the Road 5 is that they claim a half worn Road 5 has better stopping distance than a brand new PR4.
yeah, they claim that, but kinda makes me say "why" did ya cut yer nose off, in saying that....
they claim it's because the grooves ar internally tapered, so as the tire wears, the groove widens, opposite of what happens between new and half worn on the 4 prior PR versions (starts wide, gets narrower)...
with that same mental note, I would have to ask them... "do they push more water, and reduce the hydroplane effect
from the start, or
do we have to wait 3000 miles to get the optimum grip?"I've always liked the PR series, and also the Macaddam series prior to that (liked them a LOT), I just hate when a manufacturer goes full circle and tells why the 'new' product is better, when the 'older product' was supposed to be superior to everything,
it really ends up being about the rubber compound, softer wears, but grips, long wearing tires get flat spots, and don't grip... dual compound tires ... well, supposedly that multi silicate compound in the originals, and also in the old Avon AV series, once wetted, and has absorbed as much H2O as it can hold, grip good... what about dry? etc., etc., and on.
then again, this applies...
I'm afraid it will last less than the PR4. It hasn't been out long enough for anyone to actually go through it and put a review up yet.
and testing on a big fat bike like a C14, with passenger and security squad sized rider, torturing it for 5k miles... well, what next.
Hell, I'm still running PR3's..
