CST (Cheng Shin Tire) makes a whole range of tires, from the cheapest to some that are actually raced on by pros. The high end CST go by the Maxxis brand name, but made by the same company.

They also make car tires, also sold under the Maxxis name . . . but I haven't tried any of those.

So yes, agreed, stay away from the low end CST's for commuting (I use Hutchinson Intensives for commuting 700 x 25; work well for me!)
