    looking to change stock tires on my 2wd ruckus
    stock have 5" diameter

    if i switched to a tire with 4.7" will i need to adjust size of pinion?
    currently stock 24T (brushless ruckus)

    and/or do i just get spur gear with less teeth to make up for lost speed?

    I would say go up 1-2 teeth, Also the pinion will be determined by the width of the tires and how heavy they are i have a ruckus that i put duratrax sixpack sc c2 tires on and went up from 15toth to a 17tooth. I run 3s if your wondering why mine are small.

    i was also looking at proline trenchers
    but would have to gear Down for those right?
    pretty sure they are wider tire, and maybe heavier too

    Duratrax six pack tires are going to shread right away on road. Proline treanchers are great but yes you will have to grear down.

    according to duratrax they have some in 12mm hex
    not sure how they would hold up on pavement and off road

    Duratrax usually has softer compounds and probably won't last long especially on cement of any kind.

    so trenchers are a good compromise for off road while still being somewhat decent on pavement?

    Just stay below 50mph. They wont last as long on pavement no tires will. They are a little expensive but they will last a long time if maintained well enough. I also dont drive in water that much but water gets in all tires, some are affected more than others.
