Considering new S120 or S130 | My Tractor Forum
The S130 has 20x10-8 the S120 20x8-8. My X300 had 20x10-8 tires that I upgraded to 20x10-8 bar tires. There are more interesting tires now (a mix of turf and bar) that are only available in 20x10-8. The JD Parts site shows that they use the same rear wheels (8x7) so either could take 20x10-8 tires without issue.
