Winter tyre without studs
Posted: February 16th, 2013, 8:09 am
Because of legendary tyre MATADOR SM7 tyre from compound Z1 (shore is about 40 when is -10°C ...)is now wery rare (and even twice expensive than new 6years ago) in central europe and even in eastern countries like Russia, I would like to know, what tyres is used in motorsport competition in winter in another countries , when the tyres with studs are prohibited..
Here in czech are wery popular sports like Autoskijöring and hill climbing on the snow, but studs in tyres are prohibited.. the road legal tyres like Nokian Q or RSI were excelent, but now they are like ordinary winter tyre due to the age of compound (6-8years) and status "NLA" so you cannot purchase new with their excelent properities. I had their replacement Nokian R and they were wery good, but not so like RSI...
I looked for some replacement for mentioned Matadors and I´ve found Advan A034 and Dunlop SP sport 56R..but info was mostly in Japanese...
do somebody know these tyres? or another simmilar? We tried some Fedimas FM7 (same thread lime matador) but even the manufacture claims Shore about 45, it isn´t the rigt compoud for winter competition on the snow...because when we put them to the freezer their Shore rapidly increased...
