I agree that if you are getting lots of flats then you need a tougher tires. I don’t agree with riding a cheaper tire just because of miles and saving money. I’m amazed at the mileage I get out GP4000/5000 tires.
You must live in an area with flint on the road. You UK guys often talk about cutting tires. I’m lucky that that has been a non-issue for me.
When I road in real winter conditions (sand, snow, ice, slippery leaves) I just rode my gravel bike for 4-5 months until spring. It just felt a lot safer and knowing the tires were filled with sealant meant that I probably wouldn’t have to fix a flat in cold conditions.
