I remember when I bought my first 145 QV and took her to a garage as I had a slow puncture. The tyre bloke checked my tyres and said that the front two tyres would need changing soon anyhow, so you might as well change the tyres while you're here.
I looked at the tyres and they looked pretty crap, so went ahead. I was sitting in the waiting room drinking a coffee waiting for the all the clear, when I chap came in and said he couldn't get my wheels back on as the nuts that we're on were the wrong size.
The nuts had been forced on and were way to short in length. In total, only 4 nuts were the correct size on the front wheels. When I changed my wheels to Teledials, I also discovered that 2 of the nuts were the incorrect size on the back wheels.
I had to drive about 2 miles from the garage with most of the wheels having 3 nuts, so you should be cool, but I'd get it sorted.
