I’ve only ran a few types of tires for long term, Ripsaws and Bighorns (or big horn knock offs) but have rode with many in various condition with multiple.
We trail ride a lot, very little pavement, some dirt road and a lot of bushwhacking going over anything and everything to make a path. A few times a year we run in deep snow both dry and wet.
My opinion on the Ripsaw is it’s a very very tough carcass and very long lasting tire. We bought our set in 2015 for our p700 at the time, they are still going after putting them on 3 different p1000 and finally on our Polaris quad, so a total of 5 machines. Still some life but they are getting hard and chunking off now. 1000’s of miles, they go forever, but again not much pavement usage. Never a flat! They are tough. Good in rock and sticks, decent on pavement and hard packed dirt but they do vibrate at high speed. Absolute crap in snow, they don’t release the packed snow and tend to spin however they don’t chatter the drivetrain as much as others because of the limited traction. Had a couple machines up when different tires were about the same tread life and they continued to be stuck with others driving around me, same in mud. Mud isn’t exactly it’s favorite either they tend to pack up and get slick in heavy clay mud. Do ok in light mud. But again no flats so I’ll give them much credit there. They are so stiff that ride is compromised but they will run in very low pressures.
I definitely prefer the Bighorn tread pattern, it’s so much better in slick conditions so that’s what I run even with the sidewall issues, I’ve noticed the aftermarket versions of those to be better. Also BH does really well on our Wolverine but it’s much lighter especially loaded up and has less power so it’s not asking as much. The 1000 is very hard on tires imho.
I have not owned Mongrels so I can’t personally say much.
