Front tires
 

In order to get my dad's 100 running again, I changed out the front tires to some spare tires that aren't the right size. I want to put back on the correct rims next time I go home and was thinking about going with tri ribs after seeing so many good looking tractors on here that have them. I want to have them by the next time I go home and I want a quality tire and not some cheap knock off.

So my first question is, is there a certain brand of tire I should look for or steer away from, and what is a repeatable place to buy them?

My second question is what size do I need to look for? I believe that they are the stock rim but I don't have them to check what size they are at the moment. I've read that they were stock 4.00x8 and elsewhere that they are 16/6.50x8. I know the first is rim size and the second is overall dimensions but how can I tell what I have? I don't have a lot of experience with tires so you help would be much appreciated. I've attached a picture if that would help.

I'd go with 4.00x8 for the front on a narrow frame tractor, the wider tires look funny on the smaller tractors. The rims you have pictured are for the wider tires and you will need narrow rims to use the 4.00x8 tires, deestones makes a nice tri rib that's fairly inexpensive.

To add what Tim has said.....the steering of the narrow tri-rib will be greatly improved and will be easier for your dad. When I put a set on my 1200, it seemed like the front end was jacked up off of the ground and no tires were even on it---it turned that freely. I buy mine from Miller Tire for about $60/pr or $70 (maybe a little more) for tubes already in them. I would tube them to decrease the corrosion of the inner rim, but there are different schools of thought for to tube or not to tube, so you decide.

I second the Deestone tri rib 4.00x 8 that's what I put on my 126 build. I ordered the 23x10.50 ags and the fronts for $216 shipped from a fella on eBay out of Missouri, don't have the receipt with me I'm on the road.Only thing I'm bummed about is their made in Thailand, everything I've put in this build has been oem equipment or NOS, US made, gonna swap the rears out on another tractor and get American made carlisles I think, can't stand knowing their foreign tires on an old IH cub that's gonna be a show tractor , but they are 6 ply as I recall, yeah sounds like you can't go wrong with Miller, you get what you pay for

I bought my tires from the guy in mo too. Morrow tire out if Marshall mo. I have ags on the front too and it makes it very easy to steer. Tri-ribs would probably do the same, others would know better than I. I like my deestones alright, I'd buy another set.
