Question: Colorado goatheads?
Document: In addition I have used these tires off road on maintained bike paths.Overall impressionsThese tires are very well made and high quality. They wear very well and are incredibly durable. I can ride through any amount of goatheads and simply remove the remaining thorns with needle nose pliers. I have yet to have a flat with these tires.SizingMy 32mm tires measure only 30mm when mounted on Alexrims DA16 rims.
Still running the tires with normal tubes. No flats or any punctures. Have used tires off road and works well for dirt/gravel paths. Of course a wider tire would be helpful but on a road bike this offers the ability to cross dirt/grass areas without fear. Goatheads are unable to puncture the tires. I believe the combination of high density/durability rubber as well as the smartguard layer basically ensures that nothing can penetrate.
Schwalbe Marathons paired with Sunlite Thorn Resistant inner tubes are how my wife and I stopped having flats every month. We both commute on our bikes. Goatheads and other evil Sonoran desert thorns are everywhere in Phoenix. Slime filled inner tubes work until the Slime degrades in the July and August heat.Until I started using the Schwalbe/Sunlite combination, I was constantly replacing inner tubes on two bikes, fixing flats, and removing tires to pull thorn remnants from the inside.No more!
These tires are impervious to flats. I recently finished a 3500 mile solo tour through Eastern Europe on a set of the Marathon Plus 700x35 tires that I used on my Surly LHT fully loaded. That's after these same tires had been used on two 2500+ tours through SE Asia (I leave the Colorado winters every year to cycle tour through SE Asia) and have yet to have a flat on these tires. They now have about 10000 miles on them and there is still good tread although wearing in the middle.
very good tires,not particularly hard but very robust to travel on bad roads and I am very confidently do because they don't really blend with a nail or a glass -- they trusted in a long journey....super
tire provides good protection against punctures. i have the 700x32 and it fit my rim fine, tho was a little harder than normal to get on. does have a little more vibration than i used to. this is because of the somewhat aggressive tread for a road tire. I do go thru some gravel on my commute and it does great.
these tires laugh at glassthey sneer at thornsthey go thru water like uh . . . uhseriously i've only had them for 2 weeks but no flats so farno wipe outs riding in a thunderstorm no skid outs onthe corners - maybe it's just me but they feel solid a littlenarrower than i expected - what's with theobfuscatory nature of tire dimensions ?? my original tires were 29" x 1.6" and these are 700 x 35does anybody know what this means ??
rider.) Since then, I've been running 65 psi/rear & 45 psi/front for a much more satisfying ride and believe that it will have to be a pretty catastrophic moment to be concerned about a tube-pinch flat.Should I encounter any operational issues, I'll amend this review - Otherwise, consider it all good!
really durable tires, will ride over almost anything without puncturing. My only caveat is that they have such high pressure that they don't do well on gravel roads, which I encounter frequently here in Alaska
quit being a weak weight weenie. ride like you mean it.
Answer: yes
