Those 19" rims won't fit but D4 19" rims will fit over the brakes. There's a few 19" AT tyres that are half reasonable for outback travel but a set of after-market 18" rims that fit over the brakes in either alloy or steel would provide a far greater range of tyres either standard overall size or slightly larger. However AT tyres in 265/50R20 are available which might be a reasonable, low cost option that is satisfactory for your use.
Have a look at this thread..20" AT tyres - anyone have long term review?
