I believe the car ran with them in 1965 since it was advertised for sale at that time with knock off Alloys. Wheel usage in the US on production cars was drivin in part by SCCA rules. In the US the SCCA didn't allow aftermarket wheels on production cars until 1964. So, most production cars were running the steel disc or wires prior to 1964. The most popular alloy wheels in 1964 were the American racing Silverstones, JAPs, and other - Minilites soon followed.
Maybe some sport racers were running Mini-lites prior to the 1964 rule change? I think it was 1967 (or so) the SCCA limited the use of wire wheels on the track.

I am not an authority but I would be surprised if Minilite were making much other than wheels for Minis in 65, according to their website that is what they started out with; they would be Magnesium, Alluminium coming later.
Cooper seems to have been making the rose-petal design since at least 1956 (source: photos in John Cooper, Grand Prix Carpet-Bagger), from which design the Minilite was copied.
Mini-lite was, I think, one of the very many copies of the Cooper style.
Attached is a link to the modern Minilite company (it has been thro' many incarnations), the yellow and white car with the tree growing out of it looks very familiar.
