Why not just use the rename command with the group syntax?  Additionally, Nick Cox wrote an amazingly helpful command for performing a variety of renaming tasks that may be helpful in other situations (-findit renvars-).

This is completely untested but maybe you could try something like:

forv i=2/10{
loc val = 1990+(2*`i')
rename r`i'mobila mobila_`val'
}

HTH,
Billy
