I put studs on my knobby (MSP) 3 on every row, on snow and ice it's fine but on asphalt it has a weird behavior where it's gravitating towards the right which means I have to constantly parry the wheel to the left, making it a pita and exhausting to ride on asphalt. Mine’s been fine. The C-186 is a perfectly symmetrical tire left to right, so it doesn’t pull to a side. Is your tire perfectly symmetrical? Which tire is it? 1 Quote Link to comment Share on other sites More sharing options...

I've got the Kenda K262, before putting on the studs it was fine, after riding a couple of days with the studs though it settled and stopped leaning and now it feels normal again. 1 Quote Link to comment Share on other sites More sharing options...
Halig Posted March 20, 2021 Share Posted March 20, 2021 I doubt between: HEIDENAU K66 or K42. K42 is more expensive (it doesn't matter much to me either), but I don't know the differences https://www.neumaticoslider.es/neumatico-moto/heidenau/k66/80-80-16-46j-786464 https://www.neumaticoslider.es/neumatico-moto/heidenau/k42/80-80-14-43j-432516 Do you have any help about this?

I have the K42 on my seated Airwheel A3, and they are quite a bit too coarse for me to even want to try them on an EUC. The K66 link points to a 80/80-16 tire though. It should be -14 to for the V11 rim. The width is something I think you just have to take a risk with though, as I haven’t heard of anyone installing any Heidenau tire on their EUC. 1 Quote Link to comment Share on other sites More sharing options...
Halig Posted March 20, 2021 Share Posted March 20, 2021 True, thanks! This os the correct link https://www.neumaticoslider.es/neumatico-moto/heidenau/k66/80-80-14-43j-739547 I do a lot of mountain riding (half of my routes), but I don't like aggressive tires very much because of their worse grip on asphalt, higher consumption and noise. I prefer a mixed one. Maybe the K66 will be more suitable for what I want. Thanks for the info 🙂👍 Quote Link to comment Share on other sites More sharing options...
mrelwood Posted March 21, 2021 Share Posted March 21, 2021 I have never tried a tire with a center slot like the K66 has, and I’ve never read any reviews on how they work on an EUC. But there is a possibility that the behavior could be the worst of both worlds. The major issue with all off-road tires is the turning behavior; it needs to be tilted much more than a street tire in order to turn. I don’t know why that is exactly, but if tires with a center ridge turn great and knobbies turn bad, a tire with a center slot could be erratic or illogical in its turning behavior. But I simply don’t know. I trust you will tell us if you end up trying! 2 Quote Link to comment Share on other sites More sharing options...
Halig Posted March 22, 2021 Share Posted March 22, 2021 I will do that . These days my distributor was testing both and he will tell me something about his behavior. I have about 500 km left before changing the original (now it has 2600 km). Thanks for your always interesting advice 1 Quote Link to comment Share on other sites More sharing options...
Halig Posted May 26, 2021 Share Posted May 26, 2021 As I had written down, I present my latest data and experience (attention, because it seems that I speak like an expert, but I am not, I just share my impressions): Finally, the anti-puncture semimousse did not fit the wheel. My dealer tried to enter it but it was impossible. It is possible that a smaller measure would have been needed. The anti-puncture band is this: https://www.amazon.es/Tannus-ARMOUR-Plus-Semi-Mousse-Antipinchazos/dp/B084H6HJY4 After 4300 km (half offroad), the original tire was quite smooth and my dealer changed it for a HEIDENAU K66 80 / 80-14 43J, with which I am SUPER HAPPY in the first 200 km (ofroad and asfalt). I have been testing 1.5 bars of pressure and it was very good, now I am with 1.7 and it is still very good and thus I have less risk of damaging the rim. I originally tested it with 2.0 bars and the difference was HUGE (for me at least) .. it went sideways a lot, especially on short turns. I still do not know the increase in consumption. I write down all the consumption data of the long routes, km, slopes, etc. so within a few long mountain routes I will be clear if it consumes more and how much. At the moment, very very approximately, it seems that it consumes the same, although slightly more. It is logical because it has more studs than the original. It is mixed and is just what I was looking for, for greater grip in slippery areas such as mud 2 Quote Link to comment Share on other sites More sharing options...
Popular Post mrelwood Posted May 27, 2021 Popular Post Share Posted May 27, 2021 I also installed the Heidenau K66, although in size 80/90-14 and in the more winter capable Snowtex version. So far I’m loving the tire more than my previous all time favorite, the ChaoYang H-666. It really is an amazing tire! For my weight of 102kg + gear, 2.3 bars is a bit much, but 2.0 handles and feels great! For deep mud, a true knobby is of course still the king, but for everything else I use my V11 for, the K66 is the new king of the block. Fast carving on pavement, very tight 180 turns, reversing, idling on a tiny footprint, and all off-road situations... the K66 is absolute joy and fun, simply better in all regards than the H-666 which was already a nice upgrade to the original. 7 Quote Link to comment Share on other sites More sharing options...

Any modifications needed to the tire or V11? I am about to put a new tire on. Does this tire have stiff sidewalls? Also, do you recommend a stiffer inner tube? I bent my rim on my v11 and while I need to be more careful on singletrack offroad, I was looking to improve the preventative with tire and tube. Thanks!

BlckRck2014 Posted May 27, 2021 Share Posted May 27, 2021 (edited) Is the model you both installing "80/80 – 14 M/C 43J TL" ? Also, since I sometimes ride somewhat sandy mountain trails (granite sand of about 4-6 inches deep), how would the Heidenau K66 compare to the CST C-186? Thanks!

Mine is 80/90-14 Snowtex. They only make two versions of each size, Snowtex and regular, so you don’t need to worry about the speed and load ratings. 13 hours ago, BlckRck2014 said: Also, since I sometimes ride somewhat sandy mountain trails (granite sand of about 4-6 inches deep), how would the Heidenau K66 compare to the CST C-186? Regarding grip, I don’t know if the C-186 would add anything. But the major difference in other than deep mud is the tilting behavior. The C-186 needs to be tilted much more for making a turn, which might be problematic in some tight banked spots. But it might also be useful when riding straight on banked cliffs for example, since the K66 will follow the banked surface much more. For me the K66 turning behavior is so much better that I’d be drawn into choosing it over the C-186, unless you are indeed riding a lot on deep mud, snow and the like. 2 Quote Link to comment Share on other sites More sharing options...
BlckRck2014 Posted May 29, 2021 Share Posted May 29, 2021 mrelwood, thanks for answering all my questions. I'm pretty excited to get the K66 now. Im curious why you went with the 80/90-14 over the 80/80-14? Since I won't be riding snow, I assume it makes sense to not get the snowtex version. 1 Quote Link to comment Share on other sites More sharing options...
Popular Post pkinpdx Posted May 29, 2021 Popular Post Share Posted May 29, 2021 I have the k66 80/80 on my S18 and I agree its an amazing all season tire. There are a few street tires with a smoother turn profile but after a few miles I was totally used to the extra nimbleness and throw myself into turns with abandon. I would guess he chose the 80/90 because it adds a bit of tire height and keeps a similar tire circumference to his stock. Without that height he would lose a little overall top speed. I wanted a little more torque on the S18 so i was completely ok with the 80/80 being a little smaller. 4 Quote Link to comment Share on other sites More sharing options...

The speed of the V11 is easily sufficient for me as is, so I wasn’t looking for any extra. But larger is larger, and more rubber holds more air for comfort. I didn’t feel a difference between 80/80 and 80/90 on the IRC SN-26, but I still wanted to maximize the possible potential comfort aspect of the tire. I’m also under the impression that the factory installed tires are closer to having 100% height profile.

macgyvercanada Posted June 16, 2021 Share Posted June 16, 2021 Quote P.S. I will never, ever ride one of my wheels with a child's bicycle tire fitted in future! They just cannot compare to a proper MC tire for grip, stability, carving, cornering and longevity! Truth, the "kids bike" dirt tire on my V8F is nearly worn out after only a few hundred km's!

Unventor Posted June 16, 2021 Share Posted June 16, 2021 Today I got 2 different K66 tires. I am waiting for parts for my 1st batch V11. Once I got these I start to chang my control board and BT module. I fiddled with connectors on control board so they cracked. My bad. So the Master plan is to fit a K66 80/80-14 Snowtex tire on 1st batch And ...if I like it I will move on to... K66 80/80-14 all season tire on my "4th" batch (build April 2021). It is hard to tell them apart. The all season has the while line. The other is the snowtex version. I guess it is easier once it is cold to feel the difference of the rubber. 3 Quote Link to comment Share on other sites More sharing options...

The 2.75-14 size on the K262/C-186 doesn’t leave much extra clearance, but it runs fine on the V11. Edited June 30, 2021 by mrelwood Quote Link to comment Share on other sites More sharing options...

Sadly the K262 and the C-186 has zero stock anywhere in the USA. I am considering the SHINKO SR241, since there is stock, but I worry about it fitting/rubbing. I have searched heaven and earth to see if someone else has put this on the v11 and the result (fit, shave, no fit). 1 Quote Link to comment Share on other sites More sharing options...

GPSchile Posted July 2, 2021 Share Posted July 2, 2021 (edited) Mrelwood you are convincing me with the K66. I just wanted the Shinko 244 but you already confirmed it does not fit. Therefore the K66 is now my interest. The Kenda and Shinko 241, I worry about the standing leg and limiting sharp turns. However, 80/90 or 80/80? Here is my issue: where we ride we have a huge diversity of terrains. From sand to dust, hard pavement or dirt roads, snow etc. An all around would be awesome. On cars we just use the old technique of decreasing the tire pressure when riding on soft terrain (snow/sand/gravel). Then adjusting it back to normal when reaching hard floor terrain to not harm the rim. No need to change tires and quite useful on EUC. Just check the stock tire on sand with normal pressure vs 6 PSI lesser. I wonder if the K66 80/90 would be a too close fit on the sides to be able to ride with lower pressure ?

I don’t think it would. It must be deflated when removing or inserting the motor to the shell, but after that the 80/90-14 K66 fits just fine. If you don’t mind the hairs of the new tire brushing the wheel well that is. The 80/80-14 K66 is tiny enough to lower the ground clearance, so I’d have to recommend the 80/90-14 for the K66.

I totally agree about the safety of having more pneumatic cushion, specially for the rim. I am not interested on speed. So the 80/90 it is.
