tyres and mot

my insa turbo special track tyres i have noticed have some cuts to the side walls and some bits missing from the chunky bits on the tread,wots the situation with mots and tyres in this condition?..theres still massive amount of tread just bits missing as i do a lot of offroading and play days

depends if what mood the MOT man is in you should be ok i got mine though and the side wals were cut to ****
