20 inch wheels

I've only had the truck a few weeks and have been researching for a week and think I understand this but I would like to check before I make a very costly mistake because I am new to the truck scene. I am wanting to run 20" wheels with 285/55/r20 or 285/60/r20 tires and a 3 inch lift (only 20s because it is a prerunner and I plan on doing very minimal offroading). After all the research I have done I realize that the most common is a 4.5" backspace/-12mm offset. I have seen a few trucks on here with the 5.71" backspace/18mm offset though and this is where I feel i may be slightly confused. To get the -12mm offset I will have to get the 20x10 wheels, or to get the 18mm offset I can get the 20x9s. My question is what wheels will rub the least? I know both will rub, but I do not want to rub so much that my cab mounts have to be cut. Based on all of my searching I feel that the 20x10s will be fine with the -12mm off set. Am I correct?

 

Try 17's with 285/70/17 bfg's, these work great with no rubbing

i think he means he wants to run either a 285/55/20 or 285/60/20 tire

 

yea....thats how I should have said that.

I also feel like 20x10 would be too wide, but i have found quite a few on here running 20s. From previous knowledge I have found it is hard to find 20s in anything smaller than than a 20x9 so thats why I feel like someone on here has to be running 20x10. I have pmed several people with 20s but no one has replied so I started a thread.

Is anyone running 18x10s, maybe this would answer my question as well.

 

20x8.5 would be optimum for the truck, but 20x9 would work as well

 

thanks. thats what I kinda figured. Ive been looking at either the fuel octane wheels or xd monsters. Ive emailed one place to find out if either of those were available in the correct width and offset and i was told only 4.5 backspace is available in 20x10. may they be available in the smaller with and 4.5 backspace at other stores?

 

im using the OM 275-50-20 from tacoma TSS on my TRD SPORT double cab short bed 2008 no problem.
