I'm new to the F-150 world (finally graduated from my second Ranger). I'm looking for tires for my '06 4x4 XLT scab with a 2.5" NCD leveling kit and 17" factory wheels. Whats the biggest tire I can go with on this setup? Thanks for any help!

 

315/70-17 (35x12.50).

 

Will I need any kind of spacers behind the wheels or not?

 

I'd stay away from wheel spacers, especially on an 04-08 F-150 (they seem to be really sensitive). The tires are going to rub the control arms very slightly at full steering lock. If you think this will bother you, go with a slightly smaller tire like a 305/70-17 (34x12.50) or a 295/70-17 (34x12.00).

 

Tire rub doesn't bother me at all. Thanks for the info. Any recommendation for a good daily driver M/T?

 

A lot of people here seem to like the BFG KM2 tires.
They do look great

However, I've read reviews at TireRack that some people get a vibration at 65-70 they can't resolve by balancing.

 

I'd also consider the Toyo MT's, Pro Comp Xtreme MT's, Mickey THompson MTZ's and the **** Cepek Mud Country tires.
