The Stovebolt Site Forums The Parking Lot Big Bolts Tire Size on our Big Truck... Modern Size needed

Ok, I mostly deal in the Bias ply tires.

I am setting up my coe for real work. The tire size on it now is [color:#FF0000]850x20

So, The question is. What Size or Sizes do you run one your big truck?

I am mostly interested in the 20 inch rim.

I can not locate a converter to convert the bias ply size.

thanks [/color]

You don't really need to convert if you're keeping your stock 20" rims if I'm understanding you. This Yokohama online catalog shows 20" radials for bias big truck rims. They're on page 42. Stu

Just from the breif checking I've done just now, looks like a 9.00-20 would be the closest to that size. One thing you'll want to watch for is that the tires are compatible with your rims, you won't want to try to run tubeless on split rims, you'll need tube type in that case. You might consider swapping to a modern single peice wheels.

I am running 7.52 x 20 tube tires on my '46 1-1/2 ton.

The local tire dealer can get them. As long as you don't have to worry about heavy loads or long distances, practically any manufacturer's tire will do. Just check 'em frequently and make sure the pressure is correct.

My local dealer I use did not have a cross over. but, said he would check. This truck will be a working truck transporting whatever on a gooseneck. and that trailer will have radials so. I have to have modern tires.

I would change out the rims but, they are very costly. Maybe down the road.

thanks

thanks truckdog. for that link I will call a dealer for pricing. There is no dealer where I live but there is one about 16 or so, miles away which is not bad.

Thanks for the input others have posted.

I have to keep in mind that this truck will be towing a Trailer with a max load at 14,000 pounds plus the trailer weight. so, I must have real truck tires.


Thanks again

My '53 6400 has 8.25-20 bia tires on it and they are plenty big on the front. I can see where the tires rub if the wheels are turned really tight. As long as bias ply tires are fresh they and have a proper load rating there is no reason that they are of a lesser quality than a radial tire. If you don't want to replace your wheels at this time your money is best spent on getting good bias ply tires for the rims you have.

We have a pretty good Tech Tip in the Tech Tips section (of all places ...) that Grigg wrote on just this very subject -- you could start there. He has some pretty good suggestions for further research, too.
