Yeah pretty much this!
So buy track tyres with les tread to start with if it's for the track ? Would seem utterly pointless doing it to road tyres

Again, every day is a school day.
So if 888s are 'illegal' and say, Rainsports are 'legal' how is that defined? Both are road legal tyres.
It’s in the rule book, there are separate lists defining each type of tyre which is legal for that specific class.So if 888s are 'illegal' and say, Rainsports are 'legal' how is that defined? Both are road legal tyres.

Often done for racing as the tread blocks are too deep, which causes overheating and the shaving creates a nicely scuffed and grippy surface ready to go.
When a race requires a wet tyre in rain and racing wets aren't allowed in the rules a road tyre is often the preferred choice, like Uniroyal rain sports for example, I think shaving is sometimes used here. Will be corrected no doubt.

Better off asking in uk club motorsport subforum, but your best bet is probably finding a big motorsport team local who will do tyre shaving/scraping in house, or talk to your motorsport tyre supplier - I'm pretty sure the mobile championship support trucks (Avon, Michelin, etc) used to do stuff like shaving as well as fitting.
Yeah cheers, I did start a thread there and got a couple of recommendations, posting them here incase anyone needs them in future:Cambridgeshire - http://www.midlandtyreshaving.co.uk/ (shame I didn't find these guys earlier, seem pretty good)
Staffordshire - https://bpctuning.co.uk/
Everyone's favourite Demon Tweeks also do the service, however predictably for them when I called up the chap who shaves tyres there was fully booked for the time period I required - no surprise they're busy being a massive brand.
Also spoke to these guys who said they would be able to do the job, unfortunately not available in the time period I require - https://www.iconicmotorsportservices.co.uk/tyre-sh...
At least there are some options for future reference!

Since I'm doing a school day, how much do you shave off?
I assume you buy a new tyre with 8mm of tread, how much of it do you throw away? And how long does it take to shave a tyre?
Normally shave them down to around 3mm, can do less if the customer requests. I received different information from my enquiries re: time taken, some places wanted tyres sent to them then they do a whole load at once when they have received enough, another place I enquired with offered to do 4 tyres while I waited for 30 minutes I assume you buy a new tyre with 8mm of tread, how much of it do you throw away? And how long does it take to shave a tyre?
so not a massive amount of time I don't think!FWIW said:
It’s more complicated than that. They’ll be shaved to a certain profile depending on the geometry of the car setup.
More important - new tyres are softer. This is why shaved new tyres offer better performance than part worn tyres. The more heat cycles they go through the harder they get. The problem with new tyres with a lot of tread is they're so soft they deflect a lot under load and will build up heat quickly - making them softer, so they deflect and heat up more, and so on until they destroy themselves. So you want the new soft rubber for grip, without all the tread deflection.GreenV8S said:
