Can you make a set of 24.5 work? If so, this may be of interest to you, has like new Firestones all around, something I've had in my fav list for a while now....https://www.kijiji.ca/v-view-details...equestSource=b
I did have a tractor that came with one Samson on it, was only few years old and was getting some cracks when it found a new owner. Otherwise seemed like ok enough tire, was partnered with an Armstrong on the other side.
Something that I have heard mostly that is concerning, and that is warranty and how it gets dealt with. More than once, it basically comes down to you are on your own. In bias ply rear tires, for example 18.4 34, the price diff is just over $100 a piece more for something like a Goodyear Dyna Torque II over any of the Chinese brands and it is a tire the dealers will stand behind at least. I have also found many dealers will no longer deal in Chinese tires anymore, just been way too many issues.
But I know the price diff can add up on the larger ones, so be prepared to maybe eat one or two on your own, still probably cheaper than going brand name. And remember, they can have some lasting effect on resale of the tractor as well.
But no matter what you put on, do yourself a huge favor and no matter what you put on, make dam sure to have Firestone tubes in them, they are the only decent tubes left, even the natural rubber ones from Hungary quality has gone for crap. I've seen where the cheap tubes split apart in less than a couple hundred hours use, the Chinese tube are beyond total garbage.
