my 01 sr5 4x4 has oem 16" rims. I have a set of blizzaks I wish to mount, but they are 15". I have gathered various info on wether I can use 15" rims or not. my local yota dealer isn't helpful either. can anyone give me some info here?

 

If your truck originally came with 16" rims, that means you have the larger brakes, so you cannot fit 15" rims. Some trucks came with 15" rims and smaller brakes. All Limited models came with 16's and bigger brakes.
