my 2p
I’ve used 2.4 Mountain King Supersonic Black Chili’s for a couple of years now. Avoiding discussing their merits as an all-round tyre, they’ve lasted about a year each before the rear wore down enough that the knobs had haled in height. Hardly ‘worn out’ but I was also getting throughs ealant quickly due to the thin sidewalls. Basically, 2 pairs of the tyres were only just outlived by drivechain.
I used Rubebr queens for a week in Spain with Switch-Backs on my 456. 2.4 UST BC on the front, 2.2 UST non BC on the rear. After a week riding the front still had lots of the little injection moulding spikes left. The rear was more worn, difficult to say if it was proportionally more worn considering the usual wear differences. Wasn’t particularly impressed with the grip of either tyre TBH, I think I was expecting far too much and I was running too low pressures to compensate!
13th fl monk – you can currently get 2.2 RQ’s with Black Chili, only they’re normal (paper) sidewall instead of UST. Pretty sure I had one.
