I've used these in sand, gravel, mud and pavement. No punctures or ripped casing. Surprising, since they are light, thin and flexible. A good price, too, for 650's. Don't need to get more yet, I got 4. I like all black casing-look better on a white bike.
I got these tires in 42 for a Twin Six Rando. They feel the best on dry urban pavement at a low psi but with little puncture resistance they went flat within a week. Running tubeless fixed that problem. Once things get wet these tires slide more then my usual WTB Horizon or Panaracer Pasela.
I will ride these tires till they're done but won't by another.
The Pari Moto is a great tire that is easy to keep above 34kmh on both pavement and gravel. However this comes at a price of puncture protection. The tire is easily punctured by shards of gravel and goat heads. If you're going on fire roads or single tracks running with inner tubes bring a lot.
I have this set up tubeless, with sealant so that helped with the punctures. The tire itself is not advertised as tubeless compatible and you will need sealant to keep the air in. Without sealant, expect the tire to be flat in 20 minutes.
If you only plan on using this on the street the tire is great, if you're looking on riding some gravel also, look at a different tire.
