The '04 I had came with 18's but I ended up running 17's for a better selection of tires at the time. 20" tires are expensive compared to the 17's anyway!

I have the stock 18's, wanted to keep the stock tires on them for longer trips.

275/70/18 BFG A/T's on stock FX4 wheels. I do have the RAS which lifted the rear about 7/8". The tire is 1" taller than stock, same width, no fitment issues. Approx. 0.5 MPG loss in the city, no report on highway mileage yet.

Look's good Bucketman, ought to ride good too with the long wheelbase and the extra weight of the topper. Great for a long trip!

BucketMan

Thanks. Yeah, riding on the highway is about the only thing this POS does right, other than just sitting in my driveway.

The 157" WB with the cap is a sweet set up for long trips. Having a wife and 2 young kids (1 & 2) it was nice not having to wonder "Should we bring this?"

Took a nice long trip to the southern coast of Georgia this summer, everything came with us, lol.

Well i will write my first post here since this is looks like a good place for someone to lead me in the write direction. Recently i bought a 2012 FX4 Ecoboost and before it left the dealer I got a levelling kit from Ready Lift. 2'' in the front and 3'' in the rear. My research has led me to believe i can fit 33x12.5. I have looked around and think im going to go with the BFGoodrich All terrain's. I'm looking for idea's and comment's before i go out and spend $2,000 on tires what do you guys think?
