Well, full disclosure: I’m asking for my daughter (soon to be 13). I just bought her a (new to us) bike to get started racing and it came with 27.5 x 3.0’s. Wondering if it’s worth it to get a 2.6 or 2.4 set up to have options for various trail conditions?? The wheel set is wtb st i40’s. The rim seems pretty wide for a 2.4 or 2.6 tire. Definitely on the heavy side. Am I over-thinking it? I raced BMX in blue jeans in the 80’s and won a shit load of races. Sent from my iPhone using Tapatalk
