There's a few problems with these posts. Proto:87 wheels and Code 88 wheels are NOT the same thing. Code 88 are "semi-scale" Proto:87 are scale (around code 75 IIRC).
I use Semi-scale wheels and prefer Branchline, as they come in 100 & 300 packs, however they only make 33" & 36" smooth back wheels. NWSL is my back-up supplier, supplying 28" & 38" wheels, plus wheels for locomotives.
As long as your track work is up to current RP's you'll be fine. If you have any issues, might I suggest buying some of the suspension o-rings from
http://www.proto87.com/ they'll help cushion the blows. Also I'd recommend foam roadbed, as its more forgiving with the semi-scale wheels, and solder all track joints possible, or make sure they line up perfect.
Now, if your post is correct, no, Proto:87 will not work well on standard HO track. The clearances in P:87 are much tighter. again, check out all the stuff
http://www.proto87.com/ has to offer (track, switch frogs, ect).
