ah ok. here is the low down
1) make a signature with stats for your truck...you lucky i am in a good mood tonight and just checked your profile just incase its states
Year, Make, and Model:
2001 Ford Ranger
Truck Specs:4.0l SoHC, 4dr 4x4
ok now if this is true.. lets move on..if not stop reading lol...
being you have a torsion bar truck you can "lift" in thoery your front end a little if needed. BUT with a 265x75x16 tire you 999.9% will not if you are affraid. guys have installed 285x75x16 tires WITH OUT rubbing yes crazy but true. now here is pics of a few trucks with 265x75x16, honistly there not that big...
here is Zach's truck mild t-bar crank(which you dont need but he did to leave out) no rubbing
Mikes old 04 265x75x16 BFG's no t-bar crank NO rubbing
here is waynes 285
x75x16 T-bar crank no rubbing
the list goes on...
my 100% gods honist suggestion... BUY 15" RIMS INSTEAD THE FIRST TIME
a set of 265x75x16(32x10.5x16) BFG a/t will run you around $700...yes that much... a set of 33x12.5x15 BFG a/t will run you $650....honistly which sounds better....a set of 15x8 rims will fit 100% fine on your truck with out any problems...and DO NOT put spacers on thats like putting a bandaid over a rock chip its stupid...yes i went there deal with it...
get a set of 15x8 with like a 4"-3.75" BS somewhere in there. with a set of 32x11.5x15 BFG a/t's and MAYBE just maybe a slight 2 turns of the T-bars to level the truck out really with the new bigger tires you wont notice that much ride change in the truck. these will fit with out trimming, without a lift. and will still look good if you get a body lift in time..plus these tires have great road manors and get an easy 60000mile + out of them...
anymore questions ask....
edit another thing here is a tire size chart i made a while ago use it, it will help you answer some questions
