20.8-34 on 16 rims

toolz · Aug 27, 2014

I have a nice set of 20.8-34 that I'd like to mount
on a tractor with 16" rims. They should be put on
18". Anybody have problems doing this?

In general, you can go one size wider or narrower than what is meant for a given rim width. UNLESS you're going to be near the weight limit for the tires. Then they need to be on the correct size rims.

1. It will be more difficult to mount the tires because you're not only trying to stretch them over the rim, you're trying to squeeze them sideways much further than they would on a correct size rim.

2. Depending on the tire, they may look a bit "pinched" at the bead and quite rounded at the tread. The center of the tread will probably wear first.

That said, if you can manage to mount the tires without cutting the tube (a challenge regardless), they will hold air, stay round and black, keep the tractor up off the ground, and allow it to be driven and used. It's not ideal, but it will work.
