Have you been there? Im feeling probably no .........
The surface is tarmac and will wear tyres down, but TBF the same happens in the wet anyway. There is a tyrevan on site who will supply and fit new tyres for £10 each, you dont even have to take your own drift rims if thats how you want to play it. If you want to learn there are people to help, and the "playpens" are excellent for learning slidy car control without risking proper damage.
Stress on the car is not really any different whether its wet or dry, things are going to wear out faster but its not really any different from a normal trackday, and while Oulton is great for beginners its very low speed and not particularly challenging, Pod can be 3rd gear and 50mph and without being funny, doing that with a trail of smoke is what drifting its all about. Doing 100mph+ entries in 4th is even more fun, but thats a couple of steps further on
Yes, there is stuff to hit (occasional walls and other cars mainly) but its the next step up from Oulton .......... if you are worried about tyre wear then you arent really cut out to drift TBH
