I run 2.35 snakeskin Trailstar Dampf on the front and a Pacestar Dampf on the back of my Tracer 275; Stans tubeless. I also run 2.35 snakeskin Pacestar Dampf front AND back on my Sovereign; Stans tubeless. Here are my conclusions:
* The Trailstar on the front does not feel draggy and grip is good
* But the side knobs are all half-torn off and it now feel horribly imprecise cornering
* The Trailstar compound is too fragile for my rough-and-ready cornering style!
* The Sovereign is mostly for wet, slippery riding (limestone, roots and mud) and the Pacestar on the front (18 psi tubeless) is plenty grippy enough, as long as it doesn’t clog
A friend has constant problems running a Ralph on the rear – it rips or blows-off on most rides. Which is a shame as he really likes the feel of it.
I’m going to replace the damaged Trailstar Dampf on the Tracer 275 with a Pacestar.
