Re: well manered 38\" Tire?? Street use...
If you plan on mild to occasional offroading, buy a radial. If you want to use your blazer a lot offroad, and want an awesome offroad tire, buy a bias ply. Radials will also, generally, have weaker sidewalls, which could be torn by a rock easier than a bias ply. But, the radials will last longer than the bias plys, and they won't develop the flat spots like bias plys.
I bought a set of 38 TSL's and just learned to live with their bad road manners. But, it's not my daily driver, so I don't drive it much anyway. I knew a guy who had a set of 38" TSL radials and they didn't last very long in his daily driver. Have you considered the Goodyear MTR 37x12.5x15? From what I have seen, it is a tough radial, and does really well offroad, and doesn't cost $$$.
