OK, so I had some free time today and decided to do a test fit on my 35/13.50/18's (325/65/18). I used my full size spare rim and the tire I bought for a spare (Hankook Dynapro M/T). It took 70 pounds of air to get it to pop onto the rim. It fit WAY better than expected. I have to remove the front mud flap for full front articulation. I will need to trim the body mount slightly and thats it. Plenty of room between tire and UCA and it isn't even close to the skid plate. (see pics below) Whoo Hoo!!!
As you can see, it fills the wheel well very nicely.
Not even close to the skid plate
slight rubbing on front mud flap at full lock..
Not even close to the UCA
Nice spacing when facing full ahead
It is close to body mount at full lock but not touching. Still need minor trim to be safe.
