• Did you know2024

  The world's giant tire brands — Michelin, Goodyear, Bridgestone — mostly ignore the "small wheel" universe, and into that gap one company has quietly become the backbone: The Carlstar Group. The tires and wheels on a riding mower, a utility trailer, an ATV, a golf cart, a wheelbarrow and a small farm implement — completely unrelated machines to their owners — frequently come from the same firm and its brands (Carlisle, Marathon, ITP, Marastar). It's a hidden concentration in plain sight: because mass-market consumer tire makers don't bother with low-volume, high-variety specialty sizes, a single specialist ends up supplying a huge slice of everything that rolls on small or off-highway wheels. Most people never notice the brand on a mower tire, but a surprising share of those tires trace to one company.

• Substitution2024

  The airless tire that carmakers now tout as a futuristic innovation has, in the small-equipment world, been ordinary for decades — and Carlstar's Marathon brand is a reason why. Marathon popularized flat-free tires filled with polyurethane foam (or molded as solid/semi-solid) for wheelbarrows, hand trucks and mowers, eliminating flats entirely on equipment where a puncture is a maddening, frequent failure. So while "airless tires for cars" makes headlines, the humble wheelbarrow solved the no-flat problem long ago using exactly this approach. It's a reminder that supply-chain and product innovations often appear first in unglamorous, low-stakes niches — where the engineering tradeoffs (a heavier, harsher ride is fine on a wheelbarrow but not a car) are acceptable — and only later migrate, slowly, toward mainstream vehicles.

• Concentration2024

  Carlstar's corporate identity is a chain of ownership changes that consolidated specialty tires. It began as Carlisle Tire & Wheel, part of the diversified Carlisle Companies, was carved out and renamed The Carlstar Group under private-equity owner American Industrial Partners, and in 2024 was acquired by Titan International — the off-highway and agricultural tire maker (Titan, Goodyear Farm Tires). The deal stitches Carlstar's small/specialty tire breadth together with Titan's large ag and construction tires, building a more complete off-highway tire empire under one roof. For buyers it's another case where a wall of distinct brands — Carlisle, ITP, Titan, Goodyear Farm — increasingly answers to a single corporate parent, concentrating the off-highway and specialty tire market even as the brand names on the sidewalls stay the same.
