I have a 2005 Ford F150 FX4 Supercab 4 door (extended cab) and I am wanting to put new tires and rims on it. For some reason most tire companies don't seem to have the size tire I want in an Mud Terrain. Does anyone know where I can find a 285 70R18 tire that looks good or how can I determine which tire will fit my truck. I know it needs to be no smaller than an 17 I think (correct me if I am wrong). The American Outlaw Buckshot is my favorite rim so far but on there site I dont know which 17" rim will fit my truck cause I am unsure of how the bolt pattern is labeled. They give alot of numbers and I just have no idea what I am doing any help would be helpful. Here is a link to the rim.

One advise. Stay away from the 18's. Tires are expensive and hard to find.

 

Use a site like Tirerack.com to find tires that fit. Then make sure you shop around and ask your local mom n pop tire shops for prices on what you're looking for. You'll be surprised at the prices the locals give you.

I have General Grabber LT275/65 R18 tires on my F150.

 

Compared to what? 15s?

 

I'm curious here too. I was just going to get 18's since my truck currently has 18's. Would I be better off to look at 20's? I may eventually tow my Shelby so I don't want to do anything that would harm that. May go light off road.
