Xc60 D5 2009 random vibration after front tyres changed

[TheExplores]

I own a Volvo XC60 D5 2009, after replacing the front two tyres the car vibrates randomly at various speeds.

The new tyres are the exact same tyre size as the rear, just a different make. At any speed over 30 miles I get a random a vibration every so often, it’s unpleasant but only lasts a few seconds.

Front tyres : Pirelli scorpion verde P 235/60R18 107V new 10mm tread (the only correct size in stock)

Rear tyres : Avon ZX7 235/60R18 107V with almost 10mm of tread

I have had both wheels balanced twice at the garage I bought the tyres from and then again at another garage to check. I also had the wheel alignment done at the same time to see if that was the issue.

This issue wasn’t there before the new tyres, the old tyres were the same as the rear, I had a un-repairable puncher so decided to replace both fronts at the same time so to not mess with unbalanced issues ironically.

It still drives straight and true apart from the shudder.
