Hi,

I just mounted brand new 32mm Goodyear F1 Tubeless tires on 19mm internal rims, and they are measuring up at 26mm. This feels drastically wrong to me, but I was hoping to see if anyone had a similar experience - check if this is expected, and if I should see a huge increase come with stretching. Otherwise, take this as a warning that there may be some wakcy QA issues with Goodyear tires.

I hate to even ask, but have you verified that the tires are marked as 32mm and they weren't 25mm tires with the wrong packaging/labeling?

That was my first thought... the packaging, printing on the tire, and text moulded into the rubber are all consistent at 32. The packaing also looks reasonable, no mispellings, even has an 'Official Licensed Goodyear Product' holo sticker.

Based on articles when the tyre launched, I think there may be a couple things at play 1) the tyre is designed to be 32 mm actual width on a 21mm internal rim (not 100% this is the case but it is listed as the optimal width on the website) 2) Goodyear measures this width after period of inflation (24hrs?) to allow for the tyre to stretch.

Also, maybe send a support request to Goodyear direct.
