I had to be more precise... there is only TAR.GZ tarball [1].

$ cd ~/src/linux-2.6

$ tar -xf files/linux-2.6.38-rc2.tar.gz

$ tar --use-compress-program=xz -cf files/linux-2.6.38-rc2.tar.xz
linux-2.6.38-rc2/

$ ls -l linux-2.6.38-rc2.tar.*
-rw-r--r-- 1 sd sd 94091552 22. Jan 04:57 linux-2.6.38-rc2.tar.gz
-rw-r--r-- 1 sd sd 64857696 22. Jan 12:25 linux-2.6.38-rc2.tar.xz

$ du -h linux-2.6.38-rc2.tar.*
90M     linux-2.6.38-rc2.tar.gz

$ file linux-2.6.38-rc2.tar.*
linux-2.6.38-rc2.tar.gz: gzip compressed data, from Unix, last
modified: Sat Jan 22 04:33:14 2011, max compression
linux-2.6.38-rc2.tar.xz: XZ compressed data

Default compression-level of XZ is 6 (9 is best), so a 28M smaller
tarball as a number speaks for itself.
