I've been running K60s front and rear and for the street they are fine. I read stories of guys complaining about K60s not holding up in the twisties and to that I say if you want good tires for the twisties, take your F800 down and get some PR3s installed. They will be crap for offroad, but wonderful in the twisties. :)

As far as offroading goes, in most conditions the rear K60 is acceptable...the front doesn't inspire confidence once you get into the loose stuff...sand, DG, mud and so on. Since we're heading out this weekend for a couple of days done in BAJA, I'm going to take the advice of some here and install a front TKC80 and see how it performs.

Any recommendations for tire pressure from those who have both the TKC80 front and K60 rear...offroad?

Not sure about the K60 but I ran my front TKC-80 at 30 psi in Baja, did plenty of dirt and even crossed a few small rivers.

TKC 80 tire pressure

GP: I recommend experimenting. On my F800GS, at first I aired down my TKC's off road as I came from a WR 450 and rode that at low psi. After experimenting with different tire pressures off road, I have found that I now prefer the TKC at almost full recommended pressure. For me, I like 34-35 front 38-40 rear for most of my off-road riding. Deep gravel or sand, airing down helps. I did notice that when aired down to say 28-30 front and 34 rear, the bike felt less stable and less responsive. Like too much flex in the sidewall. On road at lower pressures, the tires heat up more and on road performance decreases substantially....especially highway speeds of 70 mph+. So I keep my tires fairly full and use a good gauge to get consistent results. I do have upgraded front suspension.

I know you asked TKC front, k60 rear and I don't run that. Still I say experiment and find your sweet spot and report back.

Cheers - Pangia

I have k60 in the back and tkc80 in the front. They are both run tubeless on custom rims. 26 front...and 28 in the rear....as I smack the snot out of them I will do rim, and or tire damage if I go lower. The above combo works very good for my 225 geared up rider weight, and offer a great compromise between handling and safety.


Ps 18 inch rear.

I have found diminishing return when you go below 25 psi. You get a chance to dent the rim or twist off the valve stem when you go too low. You can only get so big of contact patch. I've found that to be around 25 psi at my weight and load. Heavier loads and riders probably need a little more air to get the same size contact patch.

My bikes road handling really improved when I increased the front TKC-80 to 35 psi. Seems to do just fine in dirt and sand as well.

Just had a rear installed to replace a dead TKC80. I am noticing a buzz right around the 20-25mph mark that is not there above or below those speeds. Also the buzz will go away if I am turning enough to have the bike leaned a fair bit at the 20-25mph. The only posts I have seen in this mega-thread talk about a twisted tube. I had a shop install the tire (as I don't have a machine only spoons and bead breaker, etc) so I did not witness the tube install.

What advice can you give me? Should I pull the wheel off and try to break the bead and check for myself, take it back to the shop and have them check it, or some other plan of action? I have not put that many miles on the tire yet so I don't want to wait too long so the tube is damaged nor do I want to be a nervous Nellie by taking a perfectly fine wheel back to a shop that will probably charge me for checking.

Thanks.

That is normal on most bikes. I don't know why it only happens at that speed, but it does. I put up with it because of the good traction and handling as well as miles. You will get use to it.

I didn't get that buzz with only a rear but I did with the front. It made my rotors rattle. It was very annoying

We have K60's on three bikes...one F650GS twin, and two F650GS thumpers. Other than a bit of break in, the three of us have no complaints.

Going to run it down in Death Valley at the end of March and will post back how well it did for me. Probably going to run a MT21 on the front for better grip. I don't plan on going up many goat/mule trails while there, just the "main" dirt roads and some jeep trails.

For those of you running these on fire roads what pressure at you going down to?

Sizing?

Is anyone running a 130/80/17 or 140/80/17 on the stock 17 rim? Thoughts or feedback would be appreciated. The tread pattern seems preferable to the 150/70/17 for my purposes.

Apologies in advance if this topic has been addressed previously....

I'm now on my fourth 140/80/17. I prefer it to the 150, especially off pavement. No problems. But I gather that the 130 doesn't fit the rim well.
