My thought are that these tires are junk. They are a safety hazard on the freeway. 305 12.5 17's are by far the worst tire i have ever bought. When going down the freeway my truck follows lines in the road and it drifts making it look like im drunk trying to stay in 1 lane. It's only a matter of time before I either crash or get pulled over. On the street at speeds up to 60 it's fine but after 60 it's trying to toss me from my lane. Don't buy this tire. Just don't do it. Oh they are on my 04 f150 4x4. BF's i had were far better than these. Wish i wasn't rebuilding my engine just after purchase. The time ran out for replacement before i noticed how bad they handle so they wont help me.

What drivers say about their 305/70 R17 tires
The most recent owner reviews fitted in this size, in their own words.
If you need a tire to take you anywhere your vehicle is capable of going, this is the tire that will get you there. I've driven thousands of miles on the open road across terrain from rough pot-holed city streets to mud, sand, gravel, snow and 12000 feet above sea level crossing the Rocky Mountains and exploring desolate regions of Southern Utah in winter, at times making my own road. I would have have trusted my life to these tires when help would either have taken days to reach me or not at all. I rarely run a set of mud terrain type tires more than a couple of years (averaging 15,000 miles/year) and when it's time for my next set I will be reordering these. I only wish the raised black letter outlines came in white so I wouldn't have to paint them myself.
