I have a 2006 F-150 4x4 Supercrew. Right now it has Perelli 275x55x20's on it. I would like to change to a more aggressive all terrain tire. Any suggestions on what brands wear the best. Also, what is the largest size I can go to without causing problems or rubbing since the vehicle is not lifted.

 

I have an 07 4x4 with the factory 20's, my truck is stock height also. I recently installed a set of Cooper Zeon LTZ's 305/55/20, there is very minor rubbing at FULL lock, I mean cranked all the way to stop, once backed off just a tad the rub is gone. This tire is 33.2" diameter and 12" wide. I have been driving on the tires for about a month now and they have not rubbed yet, its like I have to try and make them rub. You definately do not want a tire any larger than this. I compared the Cooper with the Nitto Terra Grappler and the Toyo Open Country A/T, in my opinion the Cooper looked 10 times better than the other 2
The Cooper also has a better tread rating and was several hundred dollars cheaper than the others. They look and ride awsome, I would not trade them for any other tire that is out now.

 

Bfgoodrich TA Ko's. i love em

 

Yep, and you can easily get 60,000 miles out of a set of BFG AT KO's.

 

BFG's are good but in the size that you will need, expect to pay about $1500. I paid $890 for my Coopers and to me, they look alot better than the BFG's. Its all about personal preference, everyone will have a different one. What it comes down to is what you like, because in the end you will be the one driving and looking at the truck. Other peoples input is great but you have to make #1 happy.

 

Thanks everyone. I had BFG's on my 2002 Lariat and loved them. I like the looks of both tires and will have to do a little more research on the Coopers. I need to be sure I'll be able to get around off road and in the snow. Especially since I hunt a lot of waterfowl and need to be able to pull my boat out of the river in horrible conditions.
