Moving from 15" to 16" and differnt tire size, is my logic sound?

I have a 2000 SR5 4x4 ext cab. The truck came with I think 15x7 rims, I have 31x10.5 tires on the truck now. I just purchased a OME suspension kit with Dakar leafs. I was told it will give me about a 2.5" lift, the kit came with 10mm spacers for the front. I just got some 2013 TRD stock rims. From the research I've found the 15's have a 4.5" BS and the 16" have 5.25" BS. This will bring the rims in 3/4". I want to run 235x85x16. Since the 235's are about 9" wide I should have no clearance issues? Is this correct? Thanks in advance.

 

i would keep with 15 inch rims. Tires are cheaper.

 

I will keep that note in mind, since don't like to spend extra unnecessarily.... good point , tks
