Same with the KM2's...you can hear something, and they 'rumble' briefly just before you stop or as you take off from a stop. But its certainly not a 'turn up the radio to drown the tyre noise out' type thing. But different to AT tyres, that's for sure.
Collected a cheap Rhinorack AT1812 (1800mm x 1280mm) as I thought the little 800mm x 900mm Prorack off the XTrail was going to look like a pimple on the KK roof. And I got this Rhino rack cheap enough that I will be able to get my money back if I ever want to change in the future, no problems. Definately need to do the track conversion now! It a 3 mount per side rack.
Still really want a
Rhino Alloy Pioneer rack, but $1200 is more than 4x what I paid for this rack!
