Spacers needed for 12.5 tires?

I'm upgrading from the TSS standard 285/55/r20 to 33/12.5/r20. Will this require 2" (or less) spacers?

 

I just went from FN wheels and 285/75/18 to factory trd wheels and 295/70/18, I’m not sure with a factory control arm but with my Ironman offroad UCA, the tire was hitting it without spacer and couldn’t be mounted that way. I ran a 1.25” spidertrax and don’t have any rub.

 

Like stated above ^^^

Running stock wheels with 35x12.5R18" mud graps, tires clear in the rear without spacers, but in the front they hit my aftermarket UCA (Rough Country Non Adjustable tube UCA) but they do not hit my body mount

Running 1.5" spacers

 

Are you running spacers front and rear?

I bought spacers for both, but wondering if I should have skipped them on the rear

 

absolutely not, make sure you run the same thing rear as the front... I'm not sure if its dangerous not to, but it just looks silly

make sure you put red Loctite on the spacer studs before bolting them onto the hub, it'll ensure your wheel never comes off on the interstate
