I measured all 3 sets at multiple points at different pressures and different times throughout their lifespan. All 3 remained consistent in their width. The delta between '20/'21 28mm 5000’s and today is irrefutable.
I had the same issue, and for about six months, when I replaced the rear, I had a front tire that measured 31mm and a rear that measured 28. So the tire pressure I was running was 64/72. Now that I’ve switched both out and they measure 27.3mm/27.8mm my pressure has gone up to 76/78psi
With my 28s measuring almost 30, I was shocked at how low of pressure I can run. I’m a big dude at 210# and they feel amazing at 65-68 psi. I was initially quite concerned it would be too soft at max 73psi but I was shocked at how wrong I was!

Wait hold up, what rims are 13mm IW? That’s skinny af bro. Must be old as heck. My most narrow road rims are 19mm IW and those I consider too small for my gravel needs.

You must have meant 2020 not 2000 right? If you meant the year 2000 then damn you must only ride on New Year’s Day or something
Yeah this is interesting and all but if you don’t know the INNER RIM WIDTH of the wheel you’re mourning these on, this info is kinda useless.
We often will be mounting to older or newer rims that have significantly different rim widths. This width affects the “ballooning” or “light bulbing” of the tire as it expands under various amounts of pressure.
There is only so skinny you can go for 32mm for example and also only so wide you can go for 25mm for example (eg don’t mount a 25mm tire on a rim with IW 35mm, it just won’t make it past the rim width and will likely not seat/blow out/affect cornering in a very bad way).
2020 indeed. Only took you a year to catch my mistake lol.
Old ones, hence me saying old
