what kind of tire wear in general are you experiencing. I know it is based on the track but I was thinking in comparison to other cars you have owned. I am coming from driving a ntc3 and this overdrive is a whole new deal 
Having owned a FT NTC3 before the RRR, I`d say the tyre wear is quite similar, there may have been just a fraction more wear on the NTC3.
An example of tyre wear I`ve had with the RRR--
Smooth track, VHT
Starting diameters-
Front left- 59.1mm
Front right- 58.4mm
Rear left- 60.3mm
Rear right- 61.8mm
2 x 5min heats and a 15 min final took these tyres to-
Front left- 57.8mm
Front right- 58.1mm
Rear left- 58.9mm
Rear right- 60.0mm
Tyre brand- Ellegi, 40 shore front, 37 shore rear.
Cheers
