God knows how much a front tyre for the Super 3 is... I'm frightened to ask my dealer!!
We asked about this on our factory tour last October. I think the answer was "around £230 each".
I did run a puncture prevention goop in my front tyres for a while but removed it because the front end felt a bit 'lumpy'. However, that was in the (smaller) M3W tyres fitted with inner tubes. I now run tubeless tyres and carry a puncture repair kit along with a very small compressor.
