5.10x18 K270 is a run-flat?

I LOVE the 5.10 K270 I have on the front. I've ridden it hard for many many miles on every kind of terrain, and it's not even showing any wear. It's almost kinda weird... But I didn't know they were this tough until today...

I knew my front tire pressure was a little low from a recent 165 mile dualsport trip through the Oregon Cascades, about a month ago... Since then, I've been riding on it around town, sweeping alleyways, doin' wheelie's, exploring parking garages and downtown passageways, etc... Well, I finally remember to check the actual tire psi this morning before heading off to work.

Hmmmm, that's strange, the tire gauge isn't moving... must have gone bad? The second tire gauge didn't read either! So I blast some compressor air into the tire for just 1-2 seconds. Now the tire gauge reads 5psi. Well, that confirms it. I've been riding around with a deflated front tire for weeks!

Now I'm not one to miss a flat or even low tire. But these tough tires don't even hint at being flat. Only reason I knew it was low is because I deflated them down to about 14psi for the trip a month ago. And for some reason, they went ahead and deflated all the way down without me knowing. So hopefully its just a leaky air valve.

Anyway, it's kinda nice to know that a flat 5.10 K270 on the front will still get you home. Heck, it will get you to and from work and let you ride for weeks without knowing! crazzzzzzy.

Thanks for the report.

Running flat has been my flat-tire plan all along. Instead of carrying all the flat tire repair tools and supplies, I was planning to ride on the rims as far as I could.

Since it's so hard to break the bead on the rear tire, riding on a flat tire, very slowly, shouldn't be a problem.

It's good to know it is possible on the front tire as well. Looks like the K270 should be my next front tire.

Wellllll, the rear tire is a different story. I got a flat on the rear last spring... part of a chain link fence poked through the tire and tube. INSTANT flat. And it wasn't rideable. It would have destroyed the rear tire to ride it. They can do 10psi easily but not zero....

Thanks, again. More good info.

I do carry a couple of cans of Fix-a-Flat type tire repair/inflator. Thankfully, I haven't had to find out if they work.
