    Jake:

    I'm just shy of 1900 miles. Sitting here typing this and drying out! Just returned from a ride and got caught in a good downpour. The G-MAX handled perfectly, just as I expected. After hosing down the bike I'm leaving it sit in the rain. No water spots that way

    Your selection of the General Altimax HP is a good choice. Directional with lots of good sipes and heavy lugs along the edges. That tire is extremely popular with Yamaha Stratoliner Owners and is also used by numerous Goldwing GL1800 Owners. If you visit either the "Riding Dark Side Forum" or the "Goldwing Darkside Riders Forum" you'll find info on the mounting pressure and the most common "Sweet Spot Tire Pressure". You may have to tweek your tire pressure to your riding style and rider/cycle weight combination. Usually that pressure is within 1 to 2 pounds of what everyone else is using

    I'll do a quick check of the databases and see what info I can find.

    I love this idea. Since this is my first GW I have never heard of using a car tire on a bike before, except for the old Boss Hoss I rode back in the 90's. That was a large tire. It was still maneuverable although a little slow in the turns. No worse than a 250-300mm bike tire. How do you decide the car tire size and will anyone install them? I guess I'll check out the dark side forums too.

    bob, you are going to run what you want so there is little to debate. However you cannot get around science, even though the folks on the DS forums seem to think so. Physics states the more contact, the greater the likelihood of hydroplaning, it is SCIENCE, not opinion.
    I'll go one step further in pointing out that ALL of the tire manufacturers who produce tires that are routinely used by DS riders, have gone on record in stating it is NOT SAFE.
    You might want to have a look at the FD parts breakdown to see how the lateral force applied by running a CT is going to affect your FD, along with the additional 4lbs minimum your setup has over stock. You ARE loading the bearings in a way they were not designed to be loaded.
    Will you get away with running a DS setup? Sure, maybe, probably, not..... I sure wouldn't want to be that one fella who's FD goes, that is for sure.

    I have NO desire to fight with you about this topic, BUT I also don't want to see some newb reading this, think its a great idea, and then getting him/herself killed. You went shopping on the DS forums for reinforcement for what you wanted to do, and you found it. I can point out a dozen sites that claim the Holocaust never happened, back it up with all kinds of info, BUT we both know the reality.

    Thanks for sharing that with me!

    I "personally" do not endorse the use of a CT's on anyone's motorcycle other than my own, however I like to exercise my "freedom of choice" when it comes to my motorcycle, tires, oil, filter, paint color, options, grades of gas, tire pressure etc. etc. etc.

    I promise, you will be the first one I notify should I have a FD failure or other catastrophic event which resulted from my use of a CT. As this will be the my third "heavy cruiser" to wear a CT, I'm confident that my selection is "right for me".

    With you sincere concerns on this matter, I do hope that you take them to the Goldwing Darksiders Forum where hundreds of riders are routinely "throwing caution to the wind" and running CT's without failures of any sort, be it a tire or mechanical in nature.

    In closing I'd like to express my utmost confidence in "Mother Honda" to "overbuild" the F6B like every other machine they manufacture. I'm especially confident that the FD which is shared with the regular Wing are "bullet proof".

    In the interest of "Personal Safety" I admit that the owners manual clearly states not to use a "car tire" on the F6B. That info is amongst a host of other warnings to include not towing a trailer, overloading, speeding etc.

    Cordially

    Bob

    P.S. In regards to your statement of "loading the bearings" because of the of the additional 4lb. tire weight! Suggest you read and understand "unsprung/sprung weight".

    Just for gee-whiz I searched the net for motorcycle failures with car tires........................could not find a one, but I sure found lots of failures with motorcycle tires, I mean serious failures with fatal injuries, totaled bikes and multiple law suits. Kinda scary reading about all those failures, many low mileage tires, many with experienced riders who check tire pressure all the time and even the morning of the day of the failure. I'm not for or against any kind of tire, I believe we are all free to do what we want with our bikes, it's your call.

    I called a local bike tire shop today. All they do is install bike tires. You bring it in, on the bike or not, and they install it. I asked if they would install a car tire on a bike rim. "No we will not, it's not safe!" Well, alrighty then. Thanks for your OPINION. I know for a fact that it's only "unsafe" because if someone did get hurt, whether the fault of the tire or not, somebody is gonna get sued. I guess I'll have to invest in a tire mounting machine if I really want to do it.

    If hydroplaning was even an issue, then why would Harley, or anyone else, put wide car tires on a TRIKE? :think:

    For Your Info

    You might want to have a look at the FD parts breakdown to see how the lateral force applied by running a CT is going to affect your FD, along with the additional 4lbs minimum your setup has over stock. You ARE loading the bearings in a way they were not designed to be loaded.
    [/QUOTE]

    I simply had to return to this post and address your comment regarding "Lateral Force" and the "loading of bearings" because of the additional "4lbs minimum over the stock wheel/tire.

    After some research I was able to glean some great info on actual motorcycle tire weights from E-Tires Unlimited. I have to laugh because according to your assumption my FD bearings are in jeopardy of failure due to the increased weight of the 18lb G-MAX. Your assumption also suggest that any tire which weighs more than 15.5lbs (actual weight of the stock Bridgestone G704) is "overloading the bearings.

    As a refresher the stock F6B tire/wheel weight is 34lbs. The Bridgestone 180/60-R16 G704 weighs 15.5lbs. Quick math, 34lbs minus 15.5lbs gives a wheel weight of 18.5 lbs.

    Now the best part Your suggestion, that any wheel/tire combination exceeding 34 pounds total weight should not be used, has eliminated five of the six tire manufactures who have "recommended tires" for the Goldwing/F6B

    Bridgestone G704 180/60 R-16.......15.5lbs

    Metzeler ME880 180/60 R-16..........18lbs (same weight as G-MAX CT)

    Pirelli Night Dragon 180/65-16........20lbs
    180/70-16.......22lbs

    Shinko SE890 180/60-R16..............20lbs

    Michelin Commander II 180/65-16...21lbs

    Dunlop Elite 3 180/60-HR16............22lbs

    Wow! Guess Wing/F6B riders really have only one choice in a cycle tire, that being the 15.5lb Bridgestone G704

    In ending, I'll leave "Lateral Force" to "front steering tires"

    Then why would you even open this thread let alone post a giant tirade?


    That was a rhetorical question. Please don't write another ten paragraph post of nonsense.
