Problem is, the PO has fitted car load rated tyres between 91 and 94. Not good.
I quite fancy steels and can get some merc ones reasonably cheaply, they are 16"x6" ET 39. I would like to put bigger tyres on to better suit the Subaru engine fitted at the same time (can't afford Aidan's gearbox services at the moment so looking for cheaper fix).
Should I go with the steels? I can get 195x75 van rated tyres pretty cheaply but will they fit? I do realise that the speedo will be wrong but can pop my phone on the windscreen and use Android speedometer instead. The van is conservatively lowered on 50mm AVOs from brickwerks

Any help greatly appreciated, if this works I'll eBay the wheels as they have great tyres and are in pretty good nick.
