Tubeless Tire Question

I bought used tubeless wheels several months ago with tires mounted. The tires are WTB Resolute 700x42. The seller disclosed that the rear tire had developed a pinhole leak in the sidewall that he had patched from the inside. The spot was marked with a ball point pen. Ive been riding those wheels but during the last ride that same tire developed another pinhole leak in a different spot in the side wall. I broke the bead to check the sealant level. The sealant had dried and the internal patch from the previous leak was there but barely. I think the sealant had sealed that previous hole, not the patch. I finished the ride by installing a borrowed road bike tube.

At home I removed the tire, cleaned things up and Im ready to reinstall it with fresh sealant. I wonder if Im wasting my time with a faulty tire.

im obviously new to tubeless tires so I need some advice. Are side wall leaks common and is sealant okay at sealing them? Should I continue to use that tire or will it become too unreliable? How often should I check the sealant in my tires?

im guessing its good to carry an emergency tube with a tubeless tire but I can imagine the mess Id make if the sealant wasnt all dried up.

any instruction would be appreciated.

Sealant should work, even on a sidewall pinhole--larger holes will keep opening due to flex. My friend's just did this on a recent ride and he even used a DynaPlug to help plug it--his tire started spraying Stans 3 separate times during the ride. I think it's new tire time for him because a patch is going to keep flexing too. Sealant should be checked every 4-5 months.

If I were getting sidewall leaks riding on road, Id replace the tire.
if getting the same off-road, Id evaluate the trails for sharp spines.
No spines, new tire.
