I have a Ford 1210 with very dry rotted tires. I want to change to Ag tires. This little tractor is a 4x4 and I know keeping the front to rear Ratio correct is a must. The tire sizes are: Front- 20x8x10 with a 63" ground travel to make one complete rotation. Rear-29x12x15 with a 93" ground travel to make a complete rotation. I want to change to 31x12x15 on rear but what size would I need for the front. I think the ratio would be 1.476. I need the ground clearance for what I'm using this tractor for. Thanks
