Don’t forget – Zipp is answering all your tire pressure related questions this week, so if you still haven’t submitted your question, do it through the link at the bottom! We should have the answers later this week!

The world of bicycle tires is changing. Not only tires, but rim design as well. Newer hookless rim profiles with high volume tubeless tires make for a better ride with improved traction, and supposedly, lower rolling resistance. But it can be hard for a rider who’s used to putting maximum pressure into their tires before every ride to get used to the idea of riding less. Sometimes a lot less. And with that comes questions. Do these new guidelines apply to just tubeless tires? Or tubes as well? What’s the ideal rim width for a given tire size? And on, and on…

That’s exactly why Zipp has stepped up for the latest AASQ installment. While they’ve gone to great lengths to illustrate their thoughts on tire pressure with their new RollingRoad, they know there are still lots of questions out there on the subject.

      About that: The Silca calculator allows your pressure to differ by surface, with rougher surfaces getting lower pressure recommendations. At my weight, Zipp’s recommended general pressure is in line with Silca’s recommendation for dirt roads or poor pavement, assuming a 28mm tire has a measured width of 32mm on those Zipps (that’s a guesstimate; narrower measured width would lead Silca to spit out a higher recommended pressure). Silca recommends significantly higher pressures for even slightly worn pavement. At my weight of 133 lbs and assuming a 20 lb bike and 5 lb gear, Silca gave me 60.5 psi front, 62 rear for moderately worn pavement, 64/65.5 for new pavement.

    Since this is Zipp I assume that the marketing department will be responding to all of these questions? Let’s hope we are not in between two of their marketing promotions. We might get two wildly different answers.

    @Jeff, few of the Q&A have been really good, Mavic (where they answered all the questions on the old hubs free-wheel bushing issue when not regularly maintained), Enve (where they acknowledge that their faster wheels in absolute were not the wider ones) had interesting, technical questions with honest answers… the bearing one on the other hand was tainted by mkting BS… impatient to read this one
