Great site! Brand new member and I've been perusing info and topics. Excellent! My first post, I hope I'm in the right spot. I've got a few Bolens walk behind garden tractors, a Power Ho and Versa Matic models. My question is on wheel/tire size compatability. Here's the deal. Bolens filled some of their wheels with calcium chloride from the factory back in the 50's for weight, and over time, once the valves leaked, it just ate up those wheels/rims. So many Bolens wheels on the walk behinds are shot. The tire size on some of these was a 5-12, so 12" rim but 5" width, pretty narrow. I measured the wheel width, and from outside edge to edge it looks like 5". Now I have a few of the 6" width garden tractor wheels, for a 6" width tire. My question is, can you mount a 5" width tire on a 6" rim/wheel? The 5" width narrow wheels are nearly impossible to find, I've tried. I'm just curious if I could mount my 5" tire (they're in good shape, tube tires) on the 6" wheel? Thanks in advance for any help or info! Much appreciated!

Welcome to GTT :wave:

Lots of friendly folks here

We would love to see pictures of your Bolens!

Early Power-Ho's normally used the 5-12 and the Versa-Matic models used the 6-12

Both are still available on ebay.

EDIT:

I wouldn't think the 5 and 6'' tries would interchange on the rims.....

Doc he has the tires but either needs new rims or was wondering if the 5" tires will work on a 6" wide rim?

Doc / Tractorholic - Thanks for the replies. Yep, exactly, I have good 5-12 tires and wanted to try to shoe horn them onto rims/wheels that are for 6" tires. I'm starting to gather the feeling this won't work. Appreciate the responses.

I'll try to get some pics on here of my herd!

Oh and by the way the 5" tires are tube tires, so not sure if that'd make it any easier or any difference. They're tube tires, not tubeless.

Mounting 5 inch wide tires on a 6 inch wide rim will simply pull the beads apart to the width of the six inch wheel. The tubes will need to stretch more and the side walls of the tires will sit differently. try pulling the tires beads apart to the width of the 6 inch wheel and then picture how this would look with a wheel in the middle. My guess is that it should work but it may look a little strange. Hope this helps. I went through the same question when I wanted wider tires on my truck but wanted to use the original wheels. The tires should ideally be mounted on wider wheels but it works fine on narrower ones too. The side wall shape just has a slightly different shape/appearance. Now you are going the other way. (narrow tire on wider wheel) So you simply need to determine if the tire will stretch that far properly and if its appearance and function would be acceptable to you.
