Tyre pressure for FXDWG
Can you tell me what the correct pressures for the tyres on my FXDWG, the bike is year 2000, and I have changed front and rear recently, I bought Dunlops, tthe service book states 30psi front and 36psi rear for solo riding, but the garage that fitted these new tyres say that because the tyre technology is now much different to 18 years ago I should put 40psi in both front and rear. Is this correct

Welcome to the forum, the respectful thing for new members is do an introduction in the proper section before asking for assistance.
i had the same question for my 1984, I ended up using recommended tire pressure for modern similar bikes with same tires as what I was buying. I don’t like when tire stores just go by max rated tire pressure, I believe it should go by the weight of the vehicle on the tire.
What are your new tires rated for max psi?

Thanks grbrown, nice to hear from someone this side of the pond, after reading your reply I phoned my dealer, he diagrees, says tyre presures are governed by weight and style (to some degree) of bike model, but pressures must complement the suspension, he also said that running tyres at lower pressures can affect steering (particularly on bikes like FXDWG) and can lead to dwelling at corners / roundabouts aswell as excessive wear. It appears there are many opinions, I think I'll try 36 front 40 rear and see how it feels. Many thanksfor your imput.

There are some mixed messages in those words! As I suggested, check the Dunlop website - you may have to search for the Dunlop USA site, to get Harley pressures. Any figures they supply will be for your older bike with their newer tyres.
As an aside, I visited a suspension specialist at Silverstone last week, to have my 2007 Buell suspension checked and adjusted. He actually recommended reducing my tyre pressures by 2psi per wheel from the recommended levels, which is the opposite of your dealer's suggestion. One of the bikes I saw being race-prepped is a Tyco BMW BSB racer.
