What type of truck do you have?
What type of driving do you do?
What do you want to spend?
What do you expect from the tire?
Truck - Like with me, I have a 2500 HD 4x4
Driving - Most of my fdriving is on pavement so buying a nice offroad tire is stupid... the amount of time I spend off road they work just fine.
Cost - I couldn't afford a "brand name" like Good Year, Michelen, Goodrich, etc. so I went wioth the best rated "off brand" suggested by my sons shop. So far pretty sure I've put on close to if not 40k+... they are showing an odd wear pattern (rear) but that's the truck, not the tire.
Expectations - Something that would hold up even though they were "inexpensive" (not to be confused with "cheap")
The tire I have is the Yokahama Geolandar... it was the tire that had the most aggresive tread yet was not considered an offroad tire... no hum, not vibration, good tracfvtion when wet, turning, etc.
I've had brand names before and haven't proven any better than this. Just sayin...
Good Luck
