By the lack of responses, people are happy to pay that price. Nuts
It is all about volume
The tyre companies do batches of car tyres measured in millions
They do bathes of mower tyres in batches of thousands
Car tyres wear out in 2 to 4 years so they are regularly replace.
Mower tyres will last for 30 ears if you occasionally dress the sidewalls to prevent them splitting
Thus there is next to no market for mower tyres
In 10 years I have replaced 4 rear tyres an 16 fronts
And that is stretched over 300 customers and around 400 mowers.
Of the tyres replaced all but two were for hardening & cracking of the sidewalls to the point the tyres split
Fronts that wear out so do get replaced are a reasonable price but I could still buy tyres for my van cheaper than the 10" fronts for the mowers.
I know that you have been brainwashed that the free market will provide everything you ever want and a price that is easily affordable but that economic theory belongs in Disneys Fantasy Land
If you want to order them in 200 lots you can get junk tyres from China for $ 50 a piece plus freight or buy the same tyre from Walmart for $ 200 a peice.
