I destroyed two Trailblazers at normal speed in the Peak, sidewalls made of tissue paper. I’ve now fitted a 2.8 NN SS up front and a 2.8 SS Rocket Ron at the back. The latter actually has more pronounced side-knobs than the Trailblazer, but just fits with a little clearance.
So far they’ve been fine in the Peak and work well as a combination – pretty quick, decently grippy. I’d prefer Maxxis – the rubber compounds are better ime – but the prices are just ridiculous. I can’t guarantee they won’t die, but they seem, so far, to be significantly more robust than the Trailblazer.
I run around 15psi front and 16psi rear, though I think my track pump over-reads slightly. I reckon a Rekon+ front and 2.8 Rocket Ron rear would work quite nicely.
