It isn't valid for mountain bike tires, except for when you're riding your mountain bike on a smooth road. The only tests which BRR does which are likely applicable to mountain bike tires mounted to mountain bikes ridden on trails are the puncture tests, as you're likely to find sharp objects even on trails. Maybe the wet grip tests matter, if you often encounter wet large rock that you ride on. |
