Might be a dumb question, but couldn't find what I was looking for. I have an 06 rcsb sierra with stock 17's. I want to go with nnbs sierra 20's, the polished ones. My truck doesn't have tpms, so if I get the nnbs wheels would there be any issues. Do the nnbs HAVE to have the tpms monitors or can they just have standard valve stems? I've never seen nnbs wheels with tpms in person so I have nothing to go by. Thanks.
