Tires Bx1830 AG tires on a BX1500

blackmajicwoman · Mar 1, 2005

Greetings everyone. I just acquired a brand new set of AG tires that came off a BX1830. Knowing that they are slightly larger than what is called for in the BX1500 spec sheet, I not only purchased them (online), but when they came in, I had my dealer fill them with Calcium. I got the call yesterday that they we all set to be picked up. My dealer said I shouldn't have any performance issues (since the tires are slightly larger). I was quite excited to see the improved traction performance from turfs to AG's in the snow storm we had in southern NE yesterday. Before the snow started, I changed out the back tires. When I went to change out the front tires, I found the inner wheel well (rim) is deeper that the turf wheel by about an inch. With that, the tire would not fit over the front axle hub. Does anyone know if a special spacer is required (as the current BX1500 turf has a 1/4" plate space between the wheel and the hub), seeing as my BX1500 and BX1830 parts manual show the front axle on both to be identical. Or should I suck up my ignorance and purchase the BX1500 AG's for $90 each? On another note, plowing my driveway this morning of the 8" of heavy wet snow with the rear AG's installed, my traction improved by at least 100%. Any help would be greatly appreciate. Thanks.

are you certain that you weren't trying to put the rims on backward? That is what it sounds like to me. I don't have the parts book for the BX1500, but my guess is that it uses the same size rim, and only the tire changes size. Have you compared measurements between the new rim and the original rim?

Junkman,

I took a quick measurement of the "inside" of the rim. It measure at 1" deeper than that of the rim installed on the BX1500. I did not measure the outside because the valve stem is located on the "outside" and there is no way to reverse the rim as the valve stem may not fit over the hub, but I will check when I get home today. Thanks.

For front bar tires? That does not sound right, seeing that a set of four wheels/tires for the BX2200 (and I assume BX2230/1830) comes in at $296 for all four!

I don't think you would want to mix BX2200 size tires on the rear with BX1500 size on the front, if that is what you are suggesting, unless the tire size is the same, which I don't think it is, but I don't know either. The info I have is not by this computer... /forums/images/graemlins/blush.gif

The bottom line, is that you need to compare proportional sizes of the tires. If the rear BX1830 tires are larger than the BX1500 tires, then what you put on the front has to be PROPORTIONALLY larger as well, to keep the speed difference the same.

Normally, the front has a few percent overspeed when in four wheel drive. If you do something to lower this percent overspeed, or to make it negative, the results willl also be negative in the long run.

Measure the circumference of the new tires, and compare to the original tires. If the proportion is close, you are probably OK. If you are lucky, maybe they will be identical...

If the front tires work when the valve stem is on the inside, that would seem like the solution. Guess you will have to reverse the tires then. I would still do the size comparison though, to be sure I was stressing the tractor drivetrain...

If the valve stem in on the inside, then put that tire on the opposite side and it will be on the outside of the rim. I believe that you are trying to put the right front tire on the left side of the tractor and vice versa. Just call me Detective Kubota...... /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif

PS..... almost forgot to tell you to check to make sure that the tires weren't installed backwards on the rims....

Junkman and Henro,

Thanks for the advice. I spoke with Ronnie at Tractorsmart.com. First off, he charges only $39 for each front wheel/tire assembly (vice my dealer who charged $90 each). He also mentioned the same exact thing that Henro did. If I have a tire mismatch between rear and front, I run the risk of overspinning the front differential while in 4WD. Enough said, I am purchasing an entire set of AG's for the 1500 from Tractorsmart for $276. This is probably what I should have done in the first place, but I was trying to save a few bucks. Hopefully I will be able to unload this brand new set of AG's I have for a BX18xx/Bx22xx that are filled with clacium!

Thanks guys for your advice.

If you were closer I might be interested, but I'm sure shipping loaded tires isn't cost effective.

What are you in to them for? I've been toying with getting a set of bars for my BX2200 but I'm not real interested in the calcium.
