Quick question about tire sizes

[slgrafton]

OK, i read all the posts about proper tire sizing. Here is what I have:


B7100 4x4 gear drive
I am getting some binding in 4wd. I have noticed it on snowy wet and slushy roads when in 4wd.
I have:
Fronts: fairly new Firestone All Traction Field and Road 6-12. I could net find an RC number online
Rear: Fairly new Titan High Traction Lug 8-16 RC 91.
I think these tire sizes are correct for the tractor. Are they?

The tires were on the tractor when I got it last summer.

What do you mean by "binding on snowy wet and slushy roads when in 4wd"?
Normally that would be the time that you wouldn't feel a thing wrong even it did have the wrong tires.
You have the right size tires by the way.

What exactly is it doing?
Is it fighting turning or when going strait?

This may sound weird, but check your air PSI in all 4 tires, this unusual feeling can happen when you have a tire low on air psi. The Titan 8-16 are stout and even with only 5-10psi in them when in slippery conditions can be absorbing the torque applied. Rear 8-16 should have 28psi, the front 6-12 28psi according to titantire.com. It is common manufactures do no put RC's on the small front tires because they are considered lawn and garden tires, and not commercial farm tires.

See if you can find you front tire here.

The rears seem small at 91
