Ok I am going blind trying to find the proper AG tires I want for the front and rears of my 448. Does anyone have a good source and experience with this?

Some tires have 2 numbers, other's have 3, and I can't tell what is right from photos on the net.:crybaby:

For the rear, you need 8.00 X 16 or 8-16. That's the size of the turf tires your tractor came with. http://tinyurl.com/mdkaxp

On the front, you have rims that are 8 inch in diameter. These tires are often expressed with three numbers, as in 16 x 6.50 x 8. Even though the last number (rim size) remains constant, the first number expresses how wide the tire (fat) is when measured from the rim on one side to the rim on the other side. Hence, you will also see 18 x 6.50 x 8. The OEM size for your tractor is the latter. Going with fatter tires can sometimes create clearance problems. Secondly, the whole purpose of fatter tires is to provide a larger footprint (contact patch) for the tire and thusly reduce the pounds per square inch exerted on the ground under the tire. These fatter tires are often referred to as "floation tires" and are recommended when operating in really soft ground conditions.

You can use bar tread (Ag-style) tires on the front if you wish but that's normally done when the tractor has 4 wheel drive. When it's 2 wheel drive, then you run the Ag's in the opposite direction to the ones on the rear of the tractor because it's all about getting the max traction while turning the tractor as opposed to getting max traction while having both axles powering the tractor.

Manufacturer's would not put Ag tires on the front of a 2 wheel drive tractor unless the buyer demanded it and even then, it would likely arrive at the dealer with tri-rib tires and it would be up to the dealer to make the swap. The point being is there are other front tire options aside from Ag's. Either traditional tri-ribs or the Vredestein 5 rib rubber will work very well on your tractor.

The tri-ribs below would be correct for the wide rims on your Case.

You can see how fat (wide) those 16 x 6.50 x 8's are in comparison to the 4.00 x 8's shown in this link.

4.00 x 8 is the size used on many wheelbarrows and you know how skinny those are compared to what is on your Case.

Maybe you missed this discussion.

Firestone makes the proper size ag tires for the rear and any dealer should be able to get them for you if not in stock--about $140 each.

I just put a set of 16-6.50-8 Carlisle Super Lugs on the front of my 448 and 4020.
