Gravel Grinder News that you can check out by clicking the link, but here are a few "extra" observations on these interesting tires.
I had someone ask about whether or not I would/have run these tubeless. See, here's the thing about tubeless tires that are not really tubeless- you are pushing a product to do something it was not designed to do.
First of all, I have done exactly this, I have run a non-tubeless tire tubeless. I have friends that do this all the time. It is not at all uncommon. However; there are more than a few cautions and one should not extenuate the difficulties and risks involved here. In other words- you'd better be damn sure you know what you are getting yourself into and how to do it. That takes experience. I feel that I've gained a lot of exactly that in the several years I have been messing with this now.
So, back to the Knard 41's. I took a good long look at them when I got them. They are made by Innova Tire. Okay, that may or may not mean anything to you, but that raises a red flag in my mind for reasons I won't get into here. Let's just say it isn't a plus for going tubeless and leave it at that for now. Secondly, the Knard 41's were a loose fit on the supposedly tubeless ready HED Ardennes + rims. Looser than anything I've yet installed on those rims. Strike two......
Obviously that isn't going to be everyone's opinion, but I still feel that the Knard 41's are a bad candidate for tubeless conversion. There are other tires I would try first for that, but one other thing stops me there. I just do not want another tubeless tire set up to look after now. I have more tubeless set ups around here than I can take care of as it is. Adding another would be simply madness for me. I only do a tubeless set up now where it makes a big difference. As in big, 29"er mountain biking tires.
Well, so much for that. Tubed gravel road tires. Easy. Quick to repair. Roll along just fine. I'm good with tubes in those Knard 41's then, and I will not go try and ruin it all by going tubeless. Nosiree! The Knard 41's do really well with tubes too. I think they roll loose gravel and dirt great as I have them set up. A fine tire there, but not a tubeless tire. Not for me!
