One published figure — 30 TPI — and it is the coarsest here
Kenda AMRAK 27.5×2.2, 30 TPI, wire bead
A budget all-mountain tire in 27.5 × 2.2 on a wire bead, with a 30 TPI casing and an evenly spaced knob pattern.
What you are getting
A Kenda AMRAK in 27.5 × 2.2 with a 30 TPI casing and a wire bead. $34.29.
That is the whole specification. Four bullets follow and none adds a figure.
Threads per inch counts the threads in the casing under the tread. Thirty is the coarse, cheap end: thick threads, few of them, lots of rubber between. The consequences are consistent and predictable — tough against cuts, slow to roll, heavy for its size, and cheap to make.
For comparison across the American survey for this shelf: Fincci 26-inch MTB 27 TPI, Fincci 26-inch city 30 TPI, Fincci 700×38c 60 TPI, and the Panaracer GravelKing already published here 120 TPI.
Kenda publishing it at all is to its credit. Three tires on this page publish no TPI whatever.
The tread is described, and the description is the pattern
“Evenly spaced knobs for consistent bite across the tread profile”, and “a contemporary tread pattern with evenly spaced knobs… consistent grip and confident handling across diverse terrains, from rocky descents to loose gravel”.
Evenly spaced is the opposite of the semi-slick layout on the Continental and WTB tires here, where a tight center rolls and open shoulders grip. An even pattern has no fast center — it behaves the same leant over as upright, which is predictable and slower.
That makes it an all-mountain tire rather than a mixed-surface one, and the third bullet says so: “the 27.5 × 2.2 size balances traction and speed, suitable for both mountain biking and gravel adventure riding”.
“Constructed with an affordable yet high-performance compound, the Amrak delivers long-lasting durability without compromising ride quality, ideal for budget-conscious riders.”
No compound name, no durometer, no dual-compound claim. Where Maxxis says Dual Compound and Continental says BlackChili, Kenda says affordable — which at $34.29 is at least truthful about its position.
And it publishes no ETRTO, on a size where that matters
27.5 × 2.2 on a 584 mm rim is about 56-584. The Maxxis on this page gives 61-584 for a 2.40, and the Continental 50-584 for a 2.00 — so the conversion is reliable and this tire sits between them.
The buying advice on this shelf still applies: clearance at 2.2 inches is not clearance at 2.4, and a frame is measured, not assumed.
No protection layer is named at all
Not under the tread, not in the sidewall. Compare Maxxis EXO in the sidewall, Continental’s ExtraPuncture Belt under the tread, and Fincci’s 3 mm (0.12 in) nylon. On a 30 TPI casing the thickness of the rubber is the protection, which is a real if unquantified defense.
What is not published
No ETRTO, no weight, no tread depth, no pressure range, no compound, no tubeless statement, no load rating, no puncture belt. One figure — 30 TPI — and a wire bead.
