John deere g tire ballast weight

Schewe · Apr 2, 2015

Hi everyone, I've posted questions here before and everyone was very kind and helpful so I thought I'd ask another question regarding the rear tires on my tractor. I have a 48 John deere g, it had 13.6 on 13" rims ballasted with cc. The tires were shot and I got some nice 15.5 38 fire stones and put them on there unballasted, and I swear it's half the tractor it used to be with the 13.6s as far as pulling stuff around the farm. I looked up the weight for ballasting the 15.5s with cc, and it said 700 pounds each! Is this going to be too much weight? What do you guys think? They are bias tires with tubes as well

I will also add it's strictly a work tractor, not plowing, but pretty much everything else. It spins out very easy, won't bust out trees or stumps as well as it used to. Etc. It has cast centers on the back and the power tool but just doesn't seem like enough weight to get a lot of stuff done. I realize the additional 1400 pounds isn't on the tractor itself but could the additional weight have negative effects? I don't know how much weight were in the 13.6s but I think it was considerably less

I think you'll be fine filling tires to 75% but if you concerned about too much weight only fill them to 50% or in lieu of CaCl use
Propylene glycol antifreeze for less overall weight

It's pretty hard to hurt a G, unless you are trying to work it in the field with some fancy pulling motor.

My G has loaded 13.6's, and could use a little more ballast. My 70 loaded 15.5s, and seems about right.

Sir they never made 13 in rims you measure from inside of rim in the bead area you need to put 14 in rims on the tractor to get full use of 15.5 tires they round up to much on small rims and don"t make full contact with the ground get some wheel weight and forget the fluid

I had a model 50 that someone stuck 15.5-38 wide tires on it. Great for mowing swampy ground worthless for trying to pull anything ! Got some normal size rims and tires for it and it really pulled like it should. You have to have the width matched to the tractor weight. So either find something narrower or go ahead and weight it down.

Thanks for the replys everyone! Kent you are right I think they are 12" rims, if thats that factory size then i bet thats what they are. The tire has some round on it but it honestly doesn't look oversized for the rim, its strange. Anyhow, I think ill go ahead and try ballasting them full. The guy i talked to today who does it says that 13.6s should only hold about 100 pounds less each than the 15.5s, he thinks about 600 pounds full for each 13.6 and 700 for 15.5s with the heaviest CC. If it still doesn't pull well I will probably end up getting 14" rims or narrower tires. Thanks again everyone!

Weight it to whatever weight you want, but don't use Cacl, use Rim Guard or cast iron weights, you might get a puncture and you'll hate that Cacl slop then. The 13.6's loaded "bit in" good, the wide tires not loaded don't except in sand or mud. I use 14.9's on my G's and like then better than 13.6's that were on them. I didn't want to have to buy wider rims too at the time. 14.9's actually have a bigger diameter and footprint than 15.5's and are useable on the stock 12 inch rims, they were actually a factory option as 13-38's on the later G's. They just barely clear the older curved top fenders though, I use the later clamshell style anyway.
