lifts Vs. wheels n tires

i was told by les schwab that the maximum size tire i can put on my stock 2005 tacoma pre-runner access cab is a 33/1250R-20/10 with a 20x9in rim. with a 4.5 backspacing and it shouldnt rub on the A-arm. but other sources say i need a 6in lift, other say it wont fit at all.

i only want a 3in. lift.

i need to know if that size tire is going to be a problem or not if i do the 3in. lift only, or if i really do need to get the 6in. lift.

from my understanding, i thought that no matter how high u lift it, the spacing from the tire and the A-arm doesnt change...

please help.....

 

well wut about rubbing on the A-arm?

 

I just installed a readyiift 2.5 " leveling kit on my 06' and I'm trying to decide on either a P265/70/17 or a P255/75/17 with the stock rims. I'm also curious about the A arm clearance as well. With my P265/65/17's turned completely I have about 1 inch to spare. Does anybody know if I'll need spacers or should I be ok with either tire size ????

 

I just put a 3" Revtek lift with 285/70R17 on and it rubbed a little on the fender plastic, but nothing that was easy to fix with a pair of heavy duty scissors. I'm really happy with the whole setup

 

tire size doesnt mean anything when it comes to a arm clearance I had super swamper 36x15.50 's on my taco its all about the backspacing on your wheels 4.5 sounds kinda close for a 12.5 tire ...

 

but doesnt the backspacing affect my steering? if so, by how much?

also, higgins, on you 17"s how much was your backspacing?
