If it's thorns that are doing it, have you tried tubeless? That sealant stuff will seal a pretty sizeable thorn hole pretty much almost instantly. I've had rides where you look at it after, and you can see all these little pinholes of sealant poking through, but you haven't had a noticeable loss of air. I've only ever had one flat on tubeless so far, in the decade or so that I've been running it, and it was because I was being arrogant and running my tires at basically 10psi. Got it caught between two sharp rocks that basically did a snakebite on the sidewall. Still got it plugged and blown back up on the trail in under 5 minutes (which is my opinion the best part of tubeless). The cons are your tires go flat if it sits for a period of time, and you have to top them up fairly regularly, but it's worth it IMO.
