Ok so I'm fairly new to mtb biking or well biking in general. My question is that is there a tire that's a good middle of the ground? Like for instance my rides are about half of the time on trails the other half is on pavement with my lady. So I'd like a tire that's good with pavement and dirt trails but won't slide as much in the few muddy spots on the trails that I've encountered. The tires I have now are low tread level which work well on pavement and dry compacted dirt. But in really loose stuff or mud spot (mud spots usually aren't more than ten feet in length but it can be hard to get through.) there not so great. I have tubes and like a 2.1 to 2.3 sizing tire. If I'm missing info that may help please let me know. Thanks all for your help.
