Iseki Tx2140 Bolens G154 Tires

[goeduck]

The best that I can tell is that the stock rear 16-inch wheels are approx. 5.5 inches (140mm) wide and the 12-inch front wheels are approx. 3.14 inches (80mm) wide. The tractor comes with 8-16 and 5-12 tires. Does anyone know if 9.5-16 tires would fit the rear rims and 6-12 tires the front rims? The 1.44 R/F ratio would be the same.

They would fit. Usually the rim width is an inch narrower than the tire size.

That is encouraging, but with a
Rear 9.5 tread on a 5.5 wheel = 4 inch difference
Front 6 tread on a 3.14 wheel = 2.86 difference

Is more than 1"

However, the stock setup is
Rear 8 tread on a 5.5 wheel = 2.5 inch difference
Front 5 tread on a 3.14 wheel = 1.86 difference
