From what i have read there are various issues from what i can see. If someone said to me you can go and race on 1 set of tyres all day i would see that as super cheap. £25 on tyres aint too bad.when you have to put new boots on every run to be competitive it gets expensive. But like sosidge says it is peoples competitiveness that makes it expensive along with the brca rules.
If the brca made a rule of 1 dry set of tyres and a wet combo per track per day and mark them up at booking in then with round by round qualifying everyone would be in the same boat. Plus it would be cheap racing.
I have been racing touring cars for years and my tyre bill most years has been well over £1500 for a summer series, you boys should count your self lucky
