    The stock Battle Wings are great for asphalt and hard pack gravel roads...but that's not adventure riding !!!!

    What's everyone doing to find that in the "middle place" where your tires will work well everywhere (not great obviously). Trail riding, soft road conditions, moderate hill climbs and some went conditions.

    I will probably ride 70/30 (asphalt to gravel/off road) this season. Any suggestions..????

    Tough and inexpensive. Ran a front on my 950 KTM and was impressed. Not sure if their largest back tire is big enough fir the GS800 rim. Sure worth a try though.

    The Kenda's are kind of a FAN Favorite of the KLR Boy's.... but you may be right on the sizes....

    A 150 fits the KLR... 170 on the GS

    Thanks for the input

    I run a Mitas rear, either an E07 or E09 with a Dunlop 606 or 908F front.

    The tires that Pirelli provides for 17" rims have the wrong width and aspect ratio for the F800GS. The rear on the F800GS is 150 (width) 70 (aspect ratio) 17 (rim diameter). The F800GS has a very wide rear rim.

    IMHO I'd try to stick with a 150/70-17.

    If you must go smaller than 150 in the rear, the smallest I would go is 140/80-17. Any smaller and you're going to have problems with the bead breaking off the rim while riding.

    A few tires available in 150/70-17 and 90/90-21 are:

    Metzeler Tourance
    Metzeler Tourance EXP
    Metzeler Karoo
    Metzeler Karoo T
    Continental Trail Attack
    Continental TKC-80
    AVON Distanzia
    Michelin Anakee
    Bridgestone BattleWing
    Dunlop 607
    Shinko 705
    Heidenau K60 (not in the States yet, hopefully this Summer)

    etc...

    F800GS Rear ONLY:

    Kenda K270

    IMO there really is no "compromise" tire choice. Tires and suspension are the most important parts of motorcycle setup. You cannot have your cake and eat it too. My philosophy is to set up bikes with a narrow focus. I have my F8 setup optimally for the dirt, and live with it on the tarmac. I have my 998 setup optimally for the tarmac, and I don't take it in the dirt.

    I have two sets of wheels for my 12GS.

    Funny you should mention these tires;
    I put them on my KLX250 for a trip to Deal's Gap last year and LOVED them. they aren't any good in grass or soft fields, but are sweet on Gravel and dry dirt. And in my opinion, if you can drag the footpegs on a KLX, your tires are sticking pretty damn good! So when I got the F800 I went straight to the Pirellis and was dissappointed to find that there is no size that will work. If, however, they come out with the right size I will be first in line.

    Saw your rig, very nice. What sizes do you run for the rears and fronts? The Mitas rear with a Rally Raid front sounds delightful.

    What has your experience been so far with this set up?

    I am running superlaced rims from Woody on the 1200gsa and run standard rims on the F800, though I am thinking of getting Woody to run me off a pair of Excel rims in an 18/21" combo so I have more tyre choice.

    I find the Mitas is a really good wearing tyre if doing large miles... and I am not so fussed about running a full knobby on the rear for the most part, especially where the mix of road is 50/50 tar and dirt. Running a knobby on the front is more important. The Dunlop 908 is a pretty hard wearing knobby. It doesn't behave as well on the tar as the 606 but is a better off road tyre. If I was doing more sand and dirt and less tarseal I would opt for the Mitas E-09 or TKC or Rally Raid for our Aussie outback.

    Cheers :1drink

    Thanks SteveRed. On the original F*8 rims, are you running a 130/80 R17 Mitas rear? Here in Canada I seem to only be able to find that size and I'm concerned about slip of the tire on the rim during acceleration.

    Thanks man. :freaky

    Ye 130/80 R17 works ok. I am going to try the Heidenau 140 though!

    There's a 140 rear, but they're currently unobtanium (after a run on the product due to discussions here). Reportedly will be back in North America with a shipment some time this month.

    I'd guess you go a lower profile rear then, to keep the ride height the same? Or would that not matter? Lower profile = less rim protection and harsher ride, no? (Don't know, just extrapolating from experience with our Mini...)
