- black shark mud 1.5 = maxxis medusa 1.55. great tire for deep muddy grass sections (only), bit scary on wet roads, small width makes for inferior grip on uphill gravel sections because the tire only rolls on two knobs. little volume results in poor traction in rooty sections. approx. 380 g
- i will receive a pair of panaracer fire mud pro tires today and might test them on the world cup course in schladming/AUT next WE. weight: 440 g (1.8"). i guess the overall performance will be better, esp. the grip in thick glogging mud. the small medusas and bl.sharks lack some traction when it comes to steep uphills with thick mud.
- the 1.8 medusa might be THE mud specific tire to go for, but i got a great deal on panaracers on ebay, so i had to postpone buying the medusas.
- i havent tested the michlin XLs tires yet, but i read various reviews saying that these pack up with mud pretty easily.
from what i have experienced there is no do-it-all mud tire that will handle any conditons well. as i said: medusa/bl sh 1.5 for grass-only or sandy, deep muddy races. fire mud pros for changing conditions and different sections (gravel, soil, grass, roots). in general, i'd say the thicker and deeper the mud, the thinner the tires (but find out yourself!)
