Surly

Surly are an awesome company, so looking to replace some Schwalbe, I decided to jump for these to fit on my Kona Sutra with Hunt rims - ready for doing everything touring, to gravel to commuting to shopping trips.

They roll smoothly and look good. I run tubeless at about 40 - 50 psi (I'm not heavy).

But I've had 2 fail on me now, both in the same part of the tire - at the join of a nob to the bulk of the main tire, on clear road - just crack and throw sealant everywhere. No visible road nasties caused the break, just a tire fail, as far as I could tell.

Off to look for something else...

Replacements for my Fuji Wendigo fat tire bike. Avid rider, 5 days a week on dirt, gravel and paved surfaces say 100 miles a week. Customer service was excellent, shipping was fast, product was well packaged and easy to install. I tend to wear out my rear tire faster than the front and I certainly don't baby the bike at all. Switched from Maxxis brand that was discontinued and hoping these hold up better. Going from 120 tpi to 60 tpi and hoping for improved durability. Time will tell.

I have only had these tires on for about a week's worth of commutes, but even that much has made me love them. I'm a heavier rider, so the pressure is pegged at the max recommended to help me avoid pinch flats (I run them with tubes, will try tubeless maybe next spring). My commute takes me right through the center of a city along busy roads with junk from cars, broken glass, etc. littering the streets, all of which is swept by moving cars to accumulate in the bike lanes. Not one puncture or any significant lost pressure so far despite the sharp stuff on the roads! Theyre a tough set of tires, and I wouldn't be afraid at all to take them down a dirt road or gravel trail (actually, I'd be concerned about pinch flats, but I would not be worried about the tires themselves otherwise).

The tread, although road-friendly, is substantial on them and I can hear them humming along on the pavement when my surroundings are quiet...but I put these on in place of a set of hardcore knobby tires, so on pavement these feel like I'm gliding through the air in comparison. That said, if you're looking for the slickest fastest road tire out there, these aren't them; however, if you're not worried about top speed and just want a solid set of commuting or touring tires, these are looking great for that!

I�ve tried many different tires over the last few years and with out a doubt these are the easiest to mount !! Like the tread design and hoping to get many miles out of them. Very good in deep soft dirt and loose gravel.
