Hi just bought my first tractor. It is a used 4wd B1550hst. It has turf tires on the front and I'm needing to find out what size tractor lug will work with the rears. I'm guessing since it's a hydrostatic transmission the front and rear tire size needs to be matched so you dont mess up the transmission. The rear tires are 31x15.5-15 good year extra trac thay are traction tires. The fronts are 20.5x8.0-10 that are turf tires with little to no tread. I have looked online and cant find the fronts in a traction tire so I think I have to buy new wheels and go to like a r1 tread. Wondering if anyone has ran into this I dont think I'm the only person out there that has so any advice would be appreciated. Thanks
