Wouldn’t recommend Bonty XR4s with Rebas, is a bit tight. Think they are only 2.2s, but do come up big. Compared the the Panaracer XC Fire 2.1s on Mrs TWTF’s bike they are huge.
Seem like an ok tyre, grip ok, roll ok and luckily seem to shed mud!, but once they wear out* will be getting something a bit lower profile.
Got the same fork (Reba Team with 20mm Maxle light) and run the same XR4 2.2″ tyre up front on my bike as you do. It’s a very close fit isn’t it!
I love the tyres, fast, grippy, predictable but they are too high a profile really for their stated size. I can’t fit on one the back of either of my bikes oddly enough, but run one on the front of both. Rebas also have less tyre clearance than they used to have…
Run mine at about 32psi up front, any softer and I find it a bit squirmy, and it is BIG! Certainly a lot bigger than a 2.35 Maxxis HR or minion.
