I will be getting my 22" TA in summer and I need to decide which tires to go for. The choices are:

Continental 4x4 SportContact
and
Pirelli Scorpion Zero Asimmetrico

I am actually using the P-Scorpion Zero on my X5 with the 22" Hartge but I do not know the difference between the two tires. Which one should I get between this two?

thanks ^^
