The Panaracer Extreme Jet Tubular is worth 10 out of 10 in the dry but realistically only seven due to the wet grip and high cost.
Reduced contact patch
Sketchy in the wet

First things first – the Panaracer Extreme Jet Tubular is an expensive tubular tyre.
With that out of the way it’s worth considering what it’s designed for. As a sponsor of Alessandro Petacchi’s former team, Milram, the Japanese tyre manufacturer put all its tyre technology into the Jet. It has used a dual compound; normally I’m not a fan of dual compound tyres but the combination of ZSG Natural in the centre and grippier ZSG Ultima works well and provides a good dry weather ride.
In wet and greasy conditions it was a different story but I’d suggest more to do with the profile of the tyre than the compound. Panaracer has given the tyre a roughly triangular profile for less contact in a straight line and less friction. The trouble comes on off-camber roads, when grip is noticeably lacking. Bank the tyre over and it still corners but on off-camber it’s not confidence-inspiring.
A supple yet durable tyre with 290 TPI I don’t think it’s unreasonable to suggest you’ll only want to run it in the dry and at this price it’s not a bad idea.
