fyi, I'm running the 170/80-15 in the rear and still have 5mm (that's 1/5th") after 4000k's and the fronts were replaced at the same time and have the same depth of tread.
I've been inflating them at 31F and 33R with no grip issues so far in the dry or wet.
So, do we listen to Triumph's or Metzeler's recommendations. For instance Triumph know what bike the tyres are on but Metzeler has a generic for "Touring/Cruising" table with my tyre listed.
I'm more confused now than I was before, that's for sure. Maybe it gets down to a compromise between the both. Comfort wise for me, lower pressures as suggested by fogle makes sense but will the handling be less optimum for the sake of a spongier ride so to speak (boing boing - LOL).
There has to be a definitive answer or isn't it that simple cos I can understand a few psi's difference but holey dooley,
for solo riding here are the comparisons:
31psi (Triumph Recommendation for front) v 38psi (Metz) and,
33/4psi (Triumph for Rear) v 44/46 psi (Metz for Rear).
That is just a huge difference, and a whopping 10+ psi diff in the rear.
This isn't adding up (sorry) in my book.
At least I'm getting some descent wear out of the Marathons compared to the Lazertechs though. Geez, I'd probably be thinking about whether I had enough tread to go north again in a few weeks if I still had the Lazers.
