Road Wheels & Road Wheel Recommendations?

Problem I find is when I run my front tyre (Maxxis Crossmark) at a low pressure the bike starts steering itself. It feels like I'm fighting the tyre every time I turn as it wants to go in a straight line

Tyre squirm. Partly to do with have the tyre nicely bed, partly do to a flexi sidewall. Tubeless removes the first issue a fair bit, and sometimes the second one slightly.

Trial and error is the only way to find how low you can go. Just remember to note it down.
