I have a bit of 29er rubber fetish and ride the chase a lot so:
bonty 29-3 great in the spring and summer, absolute filth in the current slop fest that is this winter
as pop says maxxis beavers are great on the back, or a mud x if you don’t mind a bit of extra weight.
rocket ron 29ers great for 3 seasons and 2.35 nic on the front and 2.25 on the rear in a 29er format works a treat.
wouldn’t bother with a ralph these days as rons are grippier, faster and lighter
Maxxis ardents work well until you get a winter slop fest
bonty 29-4 are good, but sloooow and heavy
kenda are pants unless it’s dryer than a dry thing
maxxis ikon are good summer rubber
bonty ACX are ok ish
Pananracer rampage are not a as good as a nevegal, heavy and slow
if you want a more aggro front tyre for running with a stiff frontage the hans dampf 29er is great but a bit chunky
WTB stouts and dissents are epic in the filth and massive but weigh half a ton. You can get stouts cheap from unicycle.co.uk though
all based on tazzys tyre emporium experience of big wheels on the chase, peak district and big rocky bits of natural welsh lump, other’s may have a different take on it 😀
