DHF/DHR2 EXO are my default though I have tried Contis (a PITA to go tubeless and dodgy on corners) and Schwalbe (Nobby Nics – what was I thinking ?). I did try an Aggressor earlier this year, but the sidewall split after a puncture. As this is a tyre thread I’ll leave this extract from the maxxistires.de site here:
“<span> </span>
<span>IMPORTANT</span><span>At low soil temperatures (below 6 ° C) we advise against the use of the mixtures 3C MaxxTerra & 3C MaxxGrip. The soft components in the center and outer cleats tend to harden in the cold. This can result in performance losses in the curve stop, as well as – depending on the duration of application – optical defects such as cracking of the mixing “transition” on the flanks. In the cold, our DualCompound compounds, which are insensitive to temperature and always offer the same performance, whether at -15 ° C or + 20 ° C, perform considerably better.</span>

I don’t know why this is not on the UK site and I presume that there will be similar issues with softer compounds from other makes as well. The 6 degC limit is the same point at which normal car tyres become significantly inferior to all weather or Winter tyres.
