You might double check that size. I can find the 12.4-24 and the 12.4-28 but not a 26. It appears the L3301 took a 12.4 -24. You're right, they are expensive. Check car tire dealers who may sell farm tires as well. We have a chain out west called Les Schwab. They sold me a pair of rear tires for a Mitsubishi tractor for about the price of what most places wanted for one. It may even be possible to contact them for purchase on line depending on shipping charges.
