i just bought this 94 blazer s10 tahoe,it has the orignal alloy rims and sits a pretty good hiegth,just wonder what size tires would be good for it to get through some mudd?...

 

Mud terrains?! LOL. Sorry man, I am experimenting with the image code in my signature, your post was my guinea pig!

 

But your right. The only thing you need to do is put on some decent tires. The trucks alreay capable. Its not a extreme machine by any means, but it will sufice for 90% of the stuff you will encounter.
Stock 4x4= 30" tires.
2" lift 31" tires.

Tow strap. That will get you out there, you'll see and learn where your next mod will be.
