    Over inflate your tyres?

    The Gospel according to Honda says

    38 front  42 rear

    Regardless of whether solo/with pillion/with luggage

    Surely when fully laden you need a higher pressure - then lower when you're riding solo?

    I'm not exactly "lightweight" and - god forbid she ever reads this - neither is the bride - then add in 2 x fully laden panniers

    So... has anyone ever considered putting more than 38/42 in the hoops?

    Manual says front 36, rear 42.



    Beyond that, higher pressures seem to run a lot hotter, here in Nigeria, especially the rear. I keep it at the recommended as much as possible. But then again, I never have ridden the CT, 2 up.

    36/42 is also what I see in the manual but I was tempted to inflate a touch higher since I am also jumbo-sized  :158: and often ride with full panniers and topbox.  Last rear tire wore out in less than 4K miles and right down the center which I understand an overinflated tire can cause.  Maybe just coincidence but I have since aired back down to the manufacturer recommended pressures.

    Generally the first place to go to deal with weight is suspension preload, and then damping. If you look at the bikes with "wonder suspensions" that adjust automatically (or with minimal switch inputs) for number of persons and luggage (as well as riding style) -- such as BMW, Aprilia, Triumph, Ducati, KTM -- they're adjusting suspension preload and damping settings, not tire pressure.

    I’m going to swim against the tide here, and suggest a slightly lower pressure than recommended. I’m currently on the original Bridgestone tyres, with 6000 km so far. Riding fully loaded with wifey, in Europe. Neither of us are shrinking violets, and with the tyres at recommended pressure, they are wearing ok, but don’t have a lot of ‘feel’ or help soak up the bumps.
    At home we ride an 1150gs, running Mitas E07 tyres, running 4 psi under the Manufacturers recommendation. They feel great and last long, as well as giving us some confidence off road.
    As soon as the Bridgestone are done, the CT will be wearing E07’s, and I can’t wait.
    I’d swap them now, but my Scottish heritage won’t allow it :110:

    As we are seeing there are many things that impact tire life. This conversation is similar to conversations I have seen on the ST-owners forum and here are the things that I am seeing that are commonalities. Most conversations address suspension settings and tire pressure. No one really seems to address the tires themselves.

    First we need to make the decision as to what type of riding we do and then research tire that best fit our personal needs. I have seen to many times that we follow the crowd as to choices based on someone's personal view. Which is fine to a point, but we are all different in size and weight, riding styles, single or two up, etc. What we have in common is the bike itself.

    Looking at the US owner's manual these bikes depending on model are anywhere fro 608 lbs (276kg) to 635 lbs (288 kg) with a load capacity of 397 lbs (180 KG). So I am guessing based on my wife and I that most of us riding two up would easily me or exceed that load capacity once we fill our panniers. At this point suspension settings and tire pressure will only do so much. Why because we are exceeding the limit capacities of the bike.

    What I don't see or hear about is the load rating of tires that we buy for our bikes, and if you look in the owner's manual there is absolutely no mention of load rating for tires. I suspect that tires with a higher load rating will increase tire wear. This is a very unscientific assumption. But trying to research this for specific sizes may be a challenge. But when you go to a higher load rating you will typically give up something, ride, cornering, etc.

    I do know that on my ST1300, tires that provided great all around performance and ride typically did not last as long as those with harder compounds and harder carcases. Also these tire were considered Sport tour tires and not a typical tire we would run on a CT.

    Not a good idea to ride with reduced psi. The load bearing capacity of a motorcycle is not in the actual tires but the air inside them. In effect, riding with too little pressure compromises your tires, the way your bike handles, and possibly your safety.

    For certain the best way to achieve the ride you want is to adjust the suspension.  It’s a much better and safer option than playing around with your tire pressures.

    I've read that it is wise to run tire pressures between one and two psi above the manufacturer’s recommendation. That way you take into account any changes in weather (heat and cold can affect pressures). But also if you are only going to do the bare minimum and check them just once a month, it will compensate for that too, as on average tires will lose one psi every four weeks under normal riding conditions.
