Can I delete tar.gz files from my phone?

Hi everyone,

I have a samsung galaxy nexus running a custom ROM (slimbean Toro). Some may not know that there is no physical sim card and that the phone has 32GB of memory. I need to make space and I see that I have a lot of files that are compressed on the phone (such as com.android.chrome-20140825-052347.tar.gz). I know that these files are the seeds to programs once expanded and installed, however once the phone is up and running, I am not sure why I would want to keep these on the phone. I am running titanium backup and I suspect that these files might be generated by this application.

Any help would be appreciated in terms of removing them to make space for other stuff.

Thanks
