Our review

A very capable option for dryer conditions – though they're on the hefty side

At first glance you’d be forgiven for mistaking Bontrager’s G4 Team Issue for Maxxis’s popular Minion DHF. Look a little more closely though, and you’ll notice some subtle differences to the tread pattern.


The heavily ramped centre knobs help with rolling speed, and considering the tacky 42a durometer rubber compound, the G4s certainly don’t feel sluggish on the hill.

Grip in dry conditions is consistent and predictable enough that you can carve the bike hard and deep into corners with a confident understanding of the outcome. That said, when it’s a touch moist out, a G4 works better up front than on the rear because it can get a touch skatey under braking.


We’ve yet to puncture since fitting our set of dual-ply G4s, even after some out of shape high-speed wobbles through rough rock sections. They are heavy though, at 1.3kg each.
