OK, I'll do that work. Or some of it.
If you look through the WTCC_2006 folder at all the files, you'll find only two tyre files in the entire thing. One is for FWD cars. The other is for RWD cars. The same is true for the WTCC_2007 folder.
If you compare the differences between the 2006 and the 2007 FWD tyr files, you'll see two files that look almost identical. Look closely and you'll see what appears to be copy/paste files where one was created from the other. Even the documentation notation on the lines is identical. However, there are 3 lines where there is a very slight difference in the longitudinal numbers for the front tyres.
The 2007 front tyres have a 1.5% greater longitudinal grip than the 2006 fronts. There is an equally small difference in slip range where the former has an effect.
If there was an advantage, it'd be to the 2007 benefit.
