couple of newbie questions about tyres and rims

[lifty]

G'day, long time listner, first time caller,

got a '94 swb and it's time for new tires
this is my first fourby and i'm not too knowledgeable on the subject, i do try and search most things but computers and i aren't the best of friends.
So... here it comes, i've got a set of 16" CSA alloys on the zook atm, they look alright, but dunno how practical they are, tyres are slicks (to be honest thery're just 225/55R16 commodore tyres)
am looking for a decent set of rubber as i do intend to use the sierra for what it was designed for.....so what can i fit?

What works well and isn't a pain with a stock setup?

Will i be better off with smaller rims?

How wide a tyre?

current use 85% road

dunno exact specs of CSA's atm as their covered in mud

do have a full set of stock rims (one dented allong with my arse end courtesy of my mates front bar).....apparently a sierra can stop a 40 series landcruiser

thanks in advance for any help or advice offered

hello, have you got gears now? If you are still worried about the gear ratio like you said at the car wash, then get the 235 75 r15 these are only 50mm bigger than standard but offer you more choice in tyres. Getting decent near stock sized tyres for a zook on 16's is gonna be tough, I have a set of 2" offset sunnies (15inch) that i can swap with your standard wheels (are these the ones with circles) if your interested as i cant use them but will fit perfect with your WT.
