Hybrid tires (term used by Cooper, it's subsidiary companies, and some other brands) and Agressive AT (term used by Goodyear) mean the same thing.
A tire more aggressive than an AT, but less aggressive than MT. Can also mean a tire that's a crossbreed of AT & MT - typically with AT center treads and MT outer treads like Duratrac and others, but could also have AT treads on one half the tire and MT on the other like MTR-K.
Does the term Commercial Traction tire mean the same thing as Hybrid or Aggressive AT? The answer is merky and subject to opinion.
In my opinion, Commercial Traction used to mean the same thing since the CT tires were the original hybrids aka agressive ATs.
However, true CT tires have hard rubber to give long wear on heavy 3/4 ton and 1 ton trucks. That reduces traction on ice and snow, especially when used on a 1/4 ton SUV. Also, commercial traction tires were traditionally available mostly in R16 load D or E because they were intended for large work trucks, not small SUVs.
However, in recent years Goodyear, Mastercraft (Cooper), Procomp (Cooper), Dick Cepek (Cooper), and possibly others have realized SUV owners would like to use these tires on small and medium size SUVs. So now there are more load C & D choices in R16 and also now some R15 load C choices now too.
Also, as tire manufacturers have begun realizing there is demand for these tires on small, medium, and large SUVs, they've begun offering rubber compound on some of these tires that isn't as hard as a traditional CT tire. This improves snow and ice traction. Duratrac is the perfect example.
So now there are still Commercial Traction tires that fit only that category (hard rubber, mostly R16 sizes in load D or E), but there are also tires that are both CT and true hybrids (rubber not as hard as CT, and offering load C tires in R15 &/or R16.
Duratrac is a good example of a tire that is both CT and a true hybrid. This expands Goodyears market for Duratrac from CT for big work trucks only to also include small and medium size SUVs.
Procomp and Dick Cepek, and maybe Mickey Thompson, also offer tires that are both CT and true hybrid, but they don't market them as CT. They market them to light trucks and SUVs. However, I don't think they've made as good a hybrid as Goodyear has in the Duratrac and MTR-K. Though the Dick Cepek FC2 is reputedly a good hybrid.
