The Vitour Tempesta P1 X-01R (aka the X1) takes the already quick P1 platform and turns the aggression knob up. It uses a faster-activating compound that wakes up almost immediately, which means more bite, more grip, and more confidence right out of the gate.
This tire exists for one thing: short-format violence.
Autocross. Hillclimb. Short attack sessions where the run is over before most tires even wake up. The X-01R comes online quickly, works well in cooler temps, and gives you that sharp initial bite that makes the difference between a hero run and “almost had it.”
If you want a tire that hooks early and hits hard, this is it.
That said, not every driver is chasing a 60-second run. If you’re pounding out lap after lap in time attack, track days, or road racing, the P1 P-01R is the smarter play. It trades a little of that instant aggression for consistency, durability, and the ability to stay fast when the session gets long.
Think of it like this:
X-01R = maximum attack, right now
P-01R = speed you can lean on all session
Both come from the same proven P1 DNA that’s already been showing up at the pointy end of grids across the country.
The only question is how you plan to use it.
