Yeah, setting aside people running “non-approved tires”, and just looking purely at the XPLR Goodyears, I think even if you run them per the SRAM/Zipp calculator, you’re gonna get snake bites. I think that calculator is simply too optimistic for the sidewall of that tire (optimistically low).
I’ve been running them now 2-4psi higher than the calculator recommends on the slick’s (versus the inters) on terrain that is arguably MTB at times, with sharp rocks, for about 6-8 weeks, and haven’t flatted yet. I bought a pair of Inter’s to swap back to, once I flat on the Slick’s. But…fingers crossed.
