Widest (wider) R-1 Tires?

[woodlandfarms]

Can you get wider R-1's without changing out the rim? Would love to pressure my dealer if possible. The R1 tires seemed skinnier than other tractors I have looked at, but not sure if it is just and optical illusion.

Probably not, the R4's I was looking at were 17" on a 15" wheel and the widest Ag's were 14.9" so the mating wheel was 13" wide. Now I may be off a little on the exact width but the results would be the same.

Wider than????? What size are the ones you're looking at now? Generally tires will come mounted on a rim sized for that tire. Wider tire will need wider rim. Tractor tires don't just "get wider". As the width changes, USUALLY the height changes too. If the tractor you're looking at is 4WD, fronts and rears need to be "matched" in diameter required for gearing. (i.e. Taller rear/same sized front won't work) Wider tire that happens to be taller will change over-all gearing, hitch geometry, center of gravity, ect. Same for the rare instances when wider is SHORTER than original.

Radial R1s tend to "flatten" out at the tread, as opposed to the standard bias ply R1s. This may give a slight wider footprint on the ground. They are more expensive, and are usually standard equipment on the higher end full ag machines.

Michelin has a wide radial that fits on a normal rim, the XM108. It gives you a larger footprint but lightens your wallet a lot. Michelin AG - Products - XM108™

So what you might gain in traction from the radial you lose because your wallet is lighter? Sounds like a good reason to not buy radials!

The width of the tire is definitely going to be limited by rim width. In ag applications, generally the tire cross section width is APPROXIMATELY 2 inches more than the wheel width. IOW, a 18.4" tire cross section width goes on a 16 inch wheel. A 15.5" tire cross section width tire goes on a 13 inch wheel.

You cannot gain MUCH tire width without changing wheels.

See if Titan has a tire also.

The idea behind radials is that they increase traction and don't compact the ground as much which leads to better fuel economy and higher yields. They also ride a lot nicer. So they are worth it if you do a lot of farming but there is a reason they don't come standard on compacts and that is because they are not really needed and cost too much. But the XM108 does give a larger foot print without having to change rims.

Also, regardless of brand, Radial tires are a lot more money then bias. But Michelin is considered the best in farm tires.

The thing I would be concerned with is that your land is hilly and it rains alot. As you know, I've got the same problems because I'm only about 15 miles away. I personally didn't get R4's because from what I've read, you'll slide a lot more, especially on the areas slightly down hill when running across the slope. For regular hills, I only go up and down. The AGs are great for that but when it's wet, going down hill, R1's wont stop you as quick as AGs. Do you experts agree with me or have I been misunderstanding the posts on tires?

When we get together I'll show you where I put my tractor on it's side and the compound hillside that did it. You'll have a larger tractor but the theory of CG is the same.
