Note. If you are just here looking for whether you should get R14s instead of R4s the short answer is Yes, and if you can, get radials. They will far outperform any other common tire found on our small tractors. If you want the details on how I reached that conclusion, keep reading below. Hopefully this doesnt get too boring, I am an extremely information oriented person and I love sharing this information, especially if it can help someone make a better buying decision

Being as Mother nature finally provided us with some snow, I was able to complete a test that I have been wanting to do for some time. Taking the same tractor in similar snow conditions and testing, once with bias Titan ContractorT R4s and once with radial Mitas HCM(technically also an R4 but closer in style and design to an R14) to see how much of a difference there was between the tires. The tractor was my new to me MF 1233 weighing in at 2000lbs pulling a 6ft bushhog blade which weighed 500lbs. The first run was the first measurable snowfall here in Gothenburg. We had an inch of dryer snow on top of a little bit of rain, making for fairly slick conditions, but nothing too extreme. The Titan tires were struggling in 2wd but when I switched to 4, they improved and I didnt have too many major problems until I drove over a small pile of snow and was nearly unable to back out. After I got done cleaning the main areas, I went to push the piles up to the curb, and here again the R4s struggled, being only able to push small sections at a time and only then with a little momentum.
Based on this performance, I decided to upgrade to the Mitas HCMs. I also changed to fronts to a radial mud terrain pickup tire. And then... it warmed up. As it would. We averaged between 50-70 degrees for the rest of the month and into this month.:mad: On the positive side, um, it was warm I guess.? But finally, it snowed enough to complete the test. The testing conditions were a little different, but still close enough to make this test relevant. The second time we had about two inches of wet, heavy snow, on top of sleet making for very slick conditions. I was able to clear my wide to car driveway in 2wd no problem and put it in 4 for pulling the piles away from the end of the drive. In 4wd I was pulling a 3 foot high pile that came past the rear tires without any issue and I could drive all over the snow that I had piled up.
From this experience, I can say that the HCMs have well over 2x the performance than the old ones did. I was able to move piles of snow that I wouldnt even had considered with my old setup. Between that and the other major advantages of these radial tires (ride, flotation, and traction overall), I would say to anyone looking to replace or upgrade from their old tire setup to highly consider looking at these new type of tires.

If your tractor needs new tires and you move snow, absolutely go for an R14 type tire or even better get Nokian snowtires for tractors. (Same as Canadian snow contractors use). However if you're like me and have a new tractor with R4's, the best economical way is to buy an $82 USD grooving knife from Ideal and groove your tires. It adds close to the same traction as an R14 tire, I have a steep driveway where I tested it. And the "upgrade" was astonishing to me in capability.

Indeed, grooving tires does improve traction. It would be interesting to line up similar tractors with grooved R4s and R14s and see what happens. While talking with a Trelleborg rep, he told me that they are selling the HCM in Canada as a lower cost alternative to Nokians, which I found interesting. And, yes, for the pocketbooks sake, it would make the most sense to work with what you have. I was hoping to help someone looking to change to different tires, but Im new here, and still learning how to format my posts so how do you think I did in my comparison?

I for one, Caleb, really appreciate the first person comparison. You explained your experimental parameters and observations well.

Good job!

The HCM tires you linked are more like the Nokian snow tires than an R14 snow definitely will be a great snow tire just curious how they are holding up in the summer

I just got these Monday, I don't know if they have a "r xx" designation but they are similar to the Nokian. I opted out of the actual Nokian as from what little information is out there, the Nokia seems to have a softer rubber and a narrow target of snow use. I've had a pair of this style on the front for over a year and I'm very happy with them for our soils (gravelly) and winter plowing along with the road ride and expected increased tread life.

Yeah they are a great snow tire, but they are made with different rubber and a different construction than the Nokians. The tread blocks are fairly hard, so I do think that theyll hold up pretty well

Thank you. The Nokian Hakkapeliitta TRI, which seems to be the tractor tire that Nokian is known for, is a very snow oriented tire. They have recently come out with all season contractor tires, I think theyre called, but there is better priced, just as good options closer to home. If I had to guess, I would say that your tires are a R4 designation, like mine. Which brand are they?

They are BKT, a little over $1500 per copy:eek: for my size (18.4r30) The tractor came with radials and I'll never go back.

Duh me. I completely forgot that BKT had entered that market, even though, if my memory serves me correctly, they were one of the initial manufactures to that market. And, yeah, radials are the way to go. I have no clue why they only became factory on compacts within the last few years:confused3:, but there is a reason why all of the larger tractors come with them stock nowadays.

Everything is a compromise.

What works well in snow doesnt work well in soft ground and/or mud.

So likely what you gained in snow traction you sacrificed in mud traction. There is no "one size fits all" tire. Thats why the manufactures have blessed us with choices and options so we can all choose what works best for the conditions we use our tractors in

That is very true. These tires probably wouldnt do the best in mud, but they would do much better than what they replaced. IMO, this style of tires will become what the original reason of putting R4s on tractors was aiming for, a true multi-use tire.

For me it would depend on what carcass the tire is built on. If it's a modified R-4 I would steer away as I don't like their rough ride. But if it was built on an R-3 or R-1 carcass I would be very interested.

And if they are a radial then what I just said doesn't matter.

I sure wish I could get those Nokians in the size to fit the Toolcat 29x12.5-15 when the time comes.
