Regarding durability and potential sidewall cuts, plus sized tires, by design, have wider sidewalls that allow for fewer possible line choices to pick than narrower tires would when navigating tight rocky singletrack. Its in these situations where precise tire placement may be preferred more than the increased traction, rollover, and compliance that a plus tire provides. The issue becomes when a plus tire either is so well reinforced that it is incredibly heavy or the tire is made so attractively lightweight that the sidewalls are too thin to depend upon in all trail sceanarios.
Price of course comes into play here and yet again we see a place for the bicycle industry to focus it’s efforts on achieving highest possible durability, with lowest possible weight, while providing it to the consumer at the lowest possible cost. As the saying goes, however, “Light, strong, and cheap: pick two.”
What are your thoughts?
When would Plus-sized tires be too fat?
For that matter, when are 3.0, Plus-sized tires too skinny?
When are 4.0, fatbike tires optimal? What about 4.8’s?
When are 2.2 or 2.4 width tires too skinny?
Can it be quantified? (E.g., for snow greater than 3 inches deep, a 3.0 tire is too skinny to be efficient enough, etc.)
Let us know your thoughts in the comments below. We would love to carry on a discussion for which tire size you would choose and which conditions you would prefer it.
