Sometimes HP will have mix match with comfort performance depending on the brands.
Entry level - Normal day to day use, Most OE tyres for production cars
HP/Comfort performance - Comfort and/or with quiet ride
UHP - These are higher performing, better grip in wet and dry
Max - These are evn higher performing than UHP with even better wet and dry grip
Extreme - Outright dry performing tyres like semi slick, road legal race/track tyres, but these are not so good in the wet
Having said that, tyre technology have improved leaps and bound, therefore you will find some qualities not found as explained above in some of the newer tyres. For example PS3 is Max performance, but now built softer for comfort.
