75 feet of 10 gauge wire might not be enough to carry 30A.
You might need 6 or 8 because of the voltage drop.
Check your local code for guidance.
If it were me, I would absolutely run 220v from the main panel to a sub-panel in the garage. It's easy to free up space for it in the main panel by replacing 2 single pole breakers with 1 tandem breaker, freeing up 1 more space so you can install a two pole breaker for 220v service. It's better to do it all now and have the service available in the future than it is to run additional wiring later to get it done.
