I got a set of ag 18.3-16.1 tractor tires they are about the size of a 42" tire. They say mount on 16" rim. My question is has anyone on here mounted a ag tire on a vehicle rim? Do they have a different dimension for keeping the bead seated on the rim or anything like this. Any help with this question would be much appreciated. This truck will not see the highway.

you might try bggreen *(i think) on this board.

Use beadlocks or double beadlocks if they fit the rim loose.

They fit 16" wheels with no problem alot of people run them around here in FL I had a set of 16.4-16.1's and never had any problems with 16x10 american racing wheels

How much air pressure do you run?

"American Apple Farmer" offers some ag tires around that size. They actually fit a 16.1" wheel. I have seen them on a set of 16" street wheels with no problems

The 16.1 is a 16" tire. The '.1' in 16.1 designates it as a agricultural tire, thats it. I'm about to buy a 44" set and I'm gonna put them on 16 x 12's, then mount on my new rockwells.
