    Question for all y'all GSers who run offroad with TKC80's, do you air-down? If so, what pressure do you run offroad vs. on road?

    Jimmy Lewis says not to drop the pressure on GS's (I think).....

    Hmmm. Interesting. I'd think lower pressure would work better offroad. Maybe you run the risk of spinning the tire on the rim or something?

    Do a search for this topic...there are plenty of opinions and it's been discussed to death.
    My opinion? I'm with Jimmy....I've ridden behind him some and I think he knows these bikes pretty well...leave the pressure alone with TKCs and learn their feel.
    Just my $.02
    Cheers,

    I gotta say if that's what Jimmy says, I ain't arguin'.

    But, what did I buy this neat little electric air pump for then?

    Not to hijack this thread, but does anybody know if TKC80s have a mark or dot like some tires to indicate the lightest point on the tire?

    The only marks I've found are a "D6" stamped in yellow on the rear tire and an "A1" also stamped in yellow on the front tire. Are these the indicators or something else?

    This set of TKC80 was made in Korea, if that makes a difference.

    I'm planning to mount tonight or tomorrow.

    Thanks,
    David

    I lower the pressure to 20lbs on my 1200GS for off pavement riding. The bike handles much better...

    I have run the TKC80's (Touratech sponsored 1150GS) as low as 16psi for competition sections at speed. Never lost a bead even when crossed-up (sliding sideways). For pavement transfer sections, I'd go back to normal air pressures with a 12v pump and look for a 10% pressure increase from cold to hot.

    For two track or off-road, if there are a lot of rim-busters (embedded rocks), I either leave the pressures high to protect rims (high speed) or drop air to improve traction (low speed).

    Hope this adds something to the discussion.

    I had the pressure at 28 or so on the rear TKC80 on my F650 and tore the stem out of the tube in deep sand. I don't think I posted my Dualsport Solstice Ride Tale here. (Four flats to fix in one day.)

    I do not air down, seems to work fine.




    GSBS - Go by the yellow stampings. If the amount of weight to balance is excessive, deflate, rotate tire, and rebalance.

    I generally don't, but Hyde said to drop to 20 front and rear for his class - keeps a lot of small rocks from tweaking your handlebars around

    I'm with Ted on this one. I air my tires down. I have ridden with the air pressure up. The bike handles much easier with the tires aired down.

    I run the following air pressures with TKC80 or with Tourance....

    Riding solo with no gear loaded on the bike I run 20lbs front and rear.

    Riding solo with bags and gear loaded on the bike I run 25-30 lbs depending on how much I'm carrying.

    Once I air down, I keep the speed below 50 mph on asphalt (to keep the tires from getting too hot) and take the curves real easy (to keep the tires from slipping off the rims)..... I play it conservative....

    I generally air down to 30 or a little below that. You just have to be careful on the front as you will ding your rim easier.
