I can finally write a review on those cheap but very fat CST hybrid-style tires, having been riding on them for the last few months, daily, on my Six-Ten.

These are a stiff tire. I have been running low-40's psi (both road and tough-trails use) for my 140# mass with nary a single pinch-flat and only a single puncture from a fine shard of wire. Obviously their stiffness is supporting significant weight!

Since I run the low pressure for all of my riding, these heavy tires are also slow rolling of course.

I see no wear to the tread as of yet, as the contact patch at 40+psi is big.

Traction off-road is excellent based on my ability to conquer familiar steep climbs when the soil is wet or relatively dry. On-road traction has seemed very good as well.

I like that their all-black color hides the accumulation of brake wash from wet rims.

The price has only gone down a couple of Dollars since I bought them, to around $12 shipped if you can believe it.

Since the colorful sidewall label appears to be in Mandarin, I don't know what part of the Mandarin-speaking world would be riding on Imperial-sized tires, but likely the bikes are older and may have originated as late as the nineties as US market-bound overstock that ended up being "dumped" in some part of the Asian market.

So in conclusion, I am happy "getting in a better workout" riding these tires, enjoying their seemingly flat- and wear-resistant qualities while always keeping an eye out for challenging trails to explore. Luckily, around here, there are plenty of such trails that I have yet to explore or haven't visited in years.
