I put IRC's on, the tyres that come OEM with CRF300L's, for winter riding while the lanes are all TRO'd. They are a fine road-cum-gravel tyre. Unfortunately due to all the experiences (like the bike now needing repair) there's been little or no option to push them to low pressure sloppy conditions.
That's my current set-up and has been working well with no punctures for about a year. This includes motorway riding as well as MX and enduro.
