OK, so everything I've read states not to use the peel and stick vinyl tiles on particle board. Not wanting to replace the subfloor, are there any tips for laying these tiles over particle board?
I'm working with Trafficmaster ceramica vinyl tiles, installing in a small bathroom.
ANY TIPS OUT THERE?

Yes, if your bent on not having a warranty or possible issues, course it is only a bathroom. You can skim coat the PB with some vct adhesive....use the back side of a trowel. Then let it dry completely so it looks clear and does not transfer to the finger. Install away. Oh...first snap a starting line prior to skimcoating. And don't walk on it!
