Should I use slime-filled inner tubes or anti-puncture lining? My outer tyres were really worn and my inner tubes had 3 patches each (and still deflating) so I decided that I had to replace both. I have found some pretty nice outer tyres but as the place I usually ride is full of spiky plants, I thought I should either use slime-filled inner tubes or anti-puncture lining. The lining is probably a bit more expensive and difficult to find but the slime-filled inner tubes have some bad reviews.
What should I use?
Edit: I made some reaserch on tubeless systems and DIY tubeless is an option if it helps.
If you have a lot of thorns around, slime is probably not going to save you. Perhaps tubeless tyres mounted in a tubeless setup could, but they are more complicated and potentially incompatible with your old rims. Tubeless also uses something like slime (most often a latex-based sealant) but it all works much better, because there is more solid rubber in a tyre so it is much easier to seal the hole in a tyre rather than in an inner tube.
Because you have a mountain bike, it might be relatively easy to mount a tubeless tyre even on a non-tubeless specific rim. The wider the rims and tyres are, the easier it is (not talking about fat bikes). However, it is a large step you might not be willing to undertake and it does require some regular maintenance.
A tyre that comes with a good solid anti-puncture lining will be much more certain than slime if you encounter many thorns.
