I've run the Hillbilly Grid T7 up front for the last year, it's been very well suited to our Wellington NZ weather and tracks.

My local trails have very Little Rock’s and roots and this tyre digs into the soil absolutely perfectly, it grips like a mud tyre when you need it but doesn’t roll excessively slow as expected. It’s very fast for what it looks like, would roll as well as an assegai for comparison. Very happy with this product

Great traction especially on this Carolina red clay, very grippy as a front tire.

First run out with a Hillbilly on the front and a butcher on the back. They grip every where, way better than anything I've ever used before, it all in the title.

Running low pressure is like having new shocks. Great on the West Coast in the wet on rocks and roots and an excellent winter tire. Ridden them in snow and surprisingly good.

Awesome tyre, great grip. Highly recommend this product. Delivered very quickly and without any issues.

Good tire for the price.

Butch on the front, Hillbilly on the.back. Work great. Traction with the Fuel ebike going up steep in the wet NW is excellent . Work better than stock Bontranger xr5

I bought the Hillbilly (I'm Appalachian American, good thing I'm not as easily offended as some) to try out for a winter tire. Very impressed. It hooks up just as well as a Magic Mary in the muck but doesn't deflect off rocky rooty stuff like the MM does (believe me, the MM can be downright dangerous on slick roots). The new damped rubber is the real deal and while I just used it on the front, the rolling resistance wasn't as bad as I thought it would be. Out front for me now its Butcher when its hard and/or dry, Hillbilly when its damp or loose.

This thing is almost bestial in how well it grips. I run it on the rear of my single speed trail bike, and it flatly refuses to spin out, no matter how hard I try. Awesome tyre, even grips during a typical English winter ride.
