For the life of me I cannot understand why you would NOT want to put bigger rims on an old P38 :)
my speedo is spot on to the gps
kept the old rims but will probably never use them, don't have time to go 4 wheel driving....

Probably ride quality and that fact that anything over 18" on a P38a looks stupidly out of proportion as the car was designed in the 90's, anything over 18" looks bad on a D2 aswell, they weren't designed for them, so they look crap IMO, like when people put 18's on a HQ Holden, looks rubbish as they were designed for 14's.
Just my $0.02
It's all about 'period' modifications, once you start mixing styles the result is blurgh :p
Not to mention anything over 18 inch actually reduces the grip level on Tarmac on live axelled vehicles. Most people do not realise that you need a little bit of flex in the tyre wall to provide the optimum grip, too little and your tyres will skate in the wet. I'm personally not a fan of low profile tyres, as I recently found out from my cape trip that even the 18 inch rims cannot withstand a blow from a smallish rock or pothole.
Getting back on topic, if you keep your original 16" spare, make sure you also keep a set of wheel nuts and the original brace in the car otherwise you will not be able to fit it in case of a blow out.

That is a very good point
Its not the rim diameter with the axle type that reduces grip, it's the aspect/profile ratio of the tyre. I'm pretty sure Becca webster even beat the aussies offroad rock crawling using 20" wheels and live axles. The key number I think is either 50% or 45% in the profile for generating handling on the road - I think it was 50% but may stand corrected.Quote:

That is correct but you have to get home somehow. Keep the speed down and the distance short and it should be OK. Anyhow, rolling diameter of a 16" P38 alloy with stock rubber and a 19" L322 alloy with stock rubber are almost identical.Quote:
