i just bought a set of oem 20in wheels and tires at a deal i could not pass up.....i am wondering what size tires i can go with to give me a lil more side wall and overall height.......by the way i have an 06 lariat SCrew 2wd with a 2.5in leveling kit and the oem 4wd blocks in the rear...also what is a good brand........i am looking for an all terain tire.....thanks

 

If it were me, I would get 285/65/20's BFGoodrich A/T's like this guy's:

will those fit with no problem?.....i dont want any rubbing or have to do any more modifications to the suspension....

 

I agree with Cope. Dog'em suggested the 285/65/20s to me and they woked out well. With 5.5" backspacing on my wheels I have no rubbing and no trimming.

 

do the oem 20's have that back spacing?

 

I think the OEMs have either 5.5" or 6" of backspacing. I'm not 100% sure if they will fit on a 4x2 with 2.5" Autospring. I'm sure someone that knows for sure will chime in soon.

Nice looking setup bldr1

 

I don't think the tires will fit a 4x2. I have an 06 screw lariat 4x2 with a 2.5" and the factory 20's, I've replaced them, but the wheel will fit no problem. The problem will be the 285/65/20, that's like 34.5" diameter, no way without trimming, and probabbly a substantial amount. You can fit 33x12.50's no problem on the factory rim, however the rim width is 8.5" and a 305/55/20 requires at least a 9" rim width. I'm running 20x9 MM 951's with 30mm offset(6" backspace) with 305/50/20 tires(32x12.50), by the looks of it, I don't think I would have had a problem with the 305/55/20(33x12.50).

 

dang.....does anybody make an a/t tire for the oem 20's that will fit on a 4x2.......if i have to keep the same size then so be it.......i just want something other than the pirellis

 

You can run a 305 on the stockers, but you may get a little less tread wear in the centers. You can get BFG AT's in 285/55/20(32.3x11.2) $$$$ or Nitto dune grapplers(sick lookin, but no siping for wet conditions) In a 275/60/20(32.9X11.0) you have the Nitto Terra Grapplers(good looking tire with good on road characteristics and agressive at looks) or the Toyo Open Country AT( another good looking tire with good on road performance).

 

This is what my truck looked like leveled with the factory rims and tires. They look good, I just wanted something different.

 

I agree.
