yo what the fuck, spitfire doesnt sell any 60 mm (non classic shape) wheels anymore? went on their website and they had nothing
So I guess if you were looking only at the current catalog release directly on their site, I can easily understand how you might think the wheel sizes are a bit limited.
https://www.spitfirewheels.com/If you look at the options for all the wheel shapes and sizes, you might see there are other options that are just not currently in this release catalog, which even then is by no means everything that is released or available.
https://www.spitfirewheels.com/wheel-shapes/From this and from what I have looked for and found online in shops, there are still Conical Full 60mm in both 99 and 97 duro options, OG Classic wheels in 60 mm 99 duro and what might not be currently available right this minute, but the Radial Full 60 mm wheels.
That is besides the Classic 60 mm which have come out in 99 and 101 duros, or the original urethane 60 mm Classic which is a big squared off wheel, not round at all in shape.
As others had said there is also currently the Kader Radial Full 59 mm and quite a few in 58 mm, which is not far off, but all up I think the interest in wider wheels of more moderate diameters is what is trending, not so much the bigger diameter wheels, so more so the 54 through 56 sizes, than 60 mm sizes.
Thinking about past releases of Spitfire wheels, there never really have been that many options in the more recent past (think last decade or so) anyway in 60 mm size or bigger, mainly the rounder Classics, the thin square OG Classics, then the original formula wider Conical shaped Classics and once there were Big head and Multiball graphics on 59, 61 and 63 mm sizes, but that might even pre date the Formula Four wheel completely, along with the Street burners and Park burners.
I feel like there always have been more options in 60 mm wheel sizes from other brands like Bones / Powell and Santa Cruz / OJ / Slimeballs in particular, but most more diverse wheel brands have a 60 mm wheel here or there in the lineup, in much the same way that most deck brands had a token vert skater in their lineup over the years too. Not to say that only vert dudes ride 60 mm wheels either, but that is just one observation.
* Not trying to sound like a dick or anything either, just looking at all the options in wheels and there don't seem to have been that many 60 mm over the years anyway.
