This is scary! Do you have an owner's manual? Do you have a shop/service manual? Have you read the side of the tire? The web's not the greatest place to get information as important as tire pressures on a M/C that can go way more than 100mph. If I told you 70psi front, 85psi rear would you believe me? I hope not! This isn't the kind of advice I would give, not knowing what tires or what kind of riding you plan to do. If you don't have one, get an owner's manual! And no, it's NOT 85/70psi!
I also have a Buell Blast. In the Buell Blast forums, there was a huge debate back and forth about tire pressure for different tires, loads, and riding. Turned out we got really good information from the likes of Avon, Pirelli, Michellen... etc.
Call them, tell them which tires on what kind of bike. They may have to get back to you while they check with a "specialist", it opinion will be from someone that knows the tires characteristics, and hopefully a little about your bike to make a good suggestion.
I wondered about this for years and I understand the thrust of Jamo's question.
I've come to understand that the pressures listed on the tires is generally a maximum pressure and generally NOT the recommended for that specific vehicle. I go with the pressures listed on the plate attached to the vehicle whether the tires are stock or not.
I do not have stock tires on the Bonneville any more but the pressures listed on the plate seems to work perfectly.
I cannot speak for what is best on Tiger though.....
Just googled Metzler and it took me to the US Tire site, chose Duel Sport and then Filtered with bike make, model and year, gives you the options on four different tires/tyres.
On the left theres a button under Products for Recommended Tire Pressures.
Wunderful thing this T`Internet thingy
My Tourances say 36/42 on the respective sidewalls. I'm sure the Annakees said the same thing. It also states that is the max pressure at the max load too. So I think it stands to reason a lower pressure works just as well. I've been keeping mine at 41.5/35.5 the last couple of weeks and can't really notice a difference from 42/36....
