Tire pressure for the PR3/777 combo?

[notime2ride]

Just mounted the Metz/Shinko combo everyone's been raving about and can't what to see the difference it makes.  I have been running 42 lbs in the rear and 40 lbs in the front on the Dunlops that were on the bike when I got it last year.  What are you all running with the PR3/777 combo?  I'm 185 lbs.

Thanks.

38 front/ 42 rear.  Works very well for me and provides even tire wear on the front (no cupping).

How much adjustment would you make (if any) for a heavier rider?  Say 285 lbs.

According to the load data sticker on the bike, the standard air pressure setting is good up to a 441 lbs load.  The load rating of the PR3 (110 size) is slightly less at 520 lbs (58)(@42psi) from the original tires rating of 536 lbs (59)(@42psi).  Since the load rating was based on 36 psi front for the original tire, with the PR3 bumped up to 38 psi, it keeps the actual load rating approximately the same.  BTW, the front wet curb weight of the bike is 313 lbs.  Long story short, you should be fine from 38 psi to 42 psi.

Thanks Jim, I will give that a try.  Appreciate the quick answer!
