Obviously a man of great discernment. An Alfa Montreal AND an M8 😀😁

I prefer the original wheels on a Montreal, those just don't look right to me, but I suppose they are practical.

Original 1974 wheels (48 years young) are in storage ... ... Replacement wheels fitted for safety reasons

You possibly can´t run this kind of modern rubber on the old wheels. All depends on how you drive the car. I´d prefer the classic style and wouldn´t push the car too the extreme. Aren´t there any period looking replacements available? I saw at least three different styles on Montreals although only one seems to be the most original/common.

That's a good point, however if anybody is in the market you can buy off the shelf brand new wheels for the Montreal in the UK for £225 each. I can see the resemblance with the fitted wheels with the modern Alfa Romeo 'telephone dial' wheels, which in turn give a nod to the older 'pepper pot' style wheels. But low profile tyres on larger diameter wheels may need the suspension geometry changing, and almost certainly the steering geometry for safety (which I'm sure he will have done), and stickier modern rubber will wear out older suspension and driveline components (such as the differential) faster because they weren't designed for the loads, so it's not a straight swap whichever way you look at it.

As per owner RM: "Montreal's  original wheels are stored to retain originality if and when the car is sold. The originals are in a Magnesium/alloy from 1970 and the very early days of cast wheels. They were made by Campagnolo and there are known cracking incidents especially on those made for Abaths using similar formula. "

I’m with Rona!d on this - plenty of much more appropriate modern repo alloys based on the original pattern and sizing if you need them for “safety” reasons.

Much more likely IMHO that under hard use that the (70s Italian) suspension mounts etc are more likely to give way due to (possibly unseen) tin-worm than the wheels…

Montreal underwent professional restoration c.2015 after 20 years dry storage ... during storage period the engine was turned over regularly ...  restoration included new brakes / fuel lines / filters / fuel tank wash-out / dry sump lube system examination & cleaning ... subsequently followed by body refinish ... Likely that any 'tin-worm' would have been identified during both phases.
