All well and good to have have tyres for track only, but if you only have one set wheels the taking on/off all the time becomes a pain, if the car is for road use too
Most people drive the cars to the track, a fair few trailer them, but most drive to track that Ive seen
I have 2 sets wheels myself, but one set for track time of year (About 6 months and used on road too) and one set for road use only in colder months.
A couple of the road use wheels n tyres come in handy for taking to the Track as back uo, as sometimes the track day tyres are illegal to drive home on. Usually the fronts obvs.
