i have the factory 18s on my 04 lariat 4x4 and am geting 35's bfgs prob. but my question is what is the exact size i need ? i guess i asking cause of the metric thing and what will fit on the factories. and i will be adding the leveling kit first . thanks for the help!

 

that's the general concesus from what I gather. 3" leveling allows 35" tires max.

 

Most people have the 2" or 2.5" and can fit 35's with the 4wd model.

 

Please note that this is for BFG All Terrains, and I found the information on www.shoptrucktires.com; the actual diameters of sizes can vary a bit from brand to brand.

325/65-18 is 34.7 inches
305/65-18 is 33.7 inches
285/65-18 is 32.8 inches

According to others on the forum, these sizes are supposed to fit on a stock rim, but the various tire manufacturers may well tell you different.

Unfortunately, I can't tell from experience, but am doing research to make the same upgrade for myself. I'm leaning toward an Autospring 2" front level and an add-a-leaf for the rear with a set of 305's.

Best of luck!

 

I prefer the 295s myself. They equate to 33.4"

 

im rolling with the 325/60/r20 and there great!

 

I don't think you can get a BFG All Terrain in 295, but I think you can get the Mud Terrain in that size.
