Tires keep deflating

[joesmith123]

How about this?

View attachment 114617

I would honestly love something like this, 99% of the time I am in mud, this would be perfect, zero maintenance, nothing to deflate

You think if I put bigger wheels/tires on the front, it wont work?

It might work for a while, till it doesn’t.
I don’t know the specifics, but the front tire rolling circumference has to be a certain percentage of the rear to not cause problems(binding) while in 4wd.

The gearing between front and rear is set up for a specific ratio of circumference between front and rear. If you're outside the normal tolerance then you "wind up" your drive shaft - you basically load it until there's enough pressure on it to force the front tires to slip a bit. That's hard on your drive train. In mud probably doesn't matter. But if you drive on hard ground (or tarmac) in 4wd you'll break something.

I'd go with tubes, I'd put in more pressure than spec (will hold the tires on the rims better / avoid them rolling), and I'd consider as others have suggested moving to R4 tires. But if you move to R4 I'd do front and rear together, I think the different tire types (R1, R4, turf) aren't supposed to be mix and matched, again you get circumference issues.

Yes I will look into R4 tires

ok plan so far:

get new wheels

get “r4” tires

also get tubes

inflate them heavy

anyone know where I can get new wheels for it? Maybe from tractor supply

It will work great for about 1 second then your going to break something!
YOU CAN NOT change the tire ratio!

Have the tires foam filled, you'll never have a flat again!

Have the tires foam filled, you'll never have a flat again!

I did this on both my tractors about 20 years ago. Never regretted it and it’s not that expensive for smaller front tires.

I think a couple years ago on my son-in-law’s BX23S, It cost about $340 to have all four tires found filled.

I seem to recall that the price from Kubota for wheels and tires was pretty good - just buying new may be very competitive with messing around. I presume they take the same size wheels/tires as a current BX.

is this a real idea? I actually thought about doing this

what kind of foam is $340? Four cans of great stuff is about $40 plus tax from Home Depot

if this is a serious idea, I will consider doing it

 

[joesmith123]

I’m gonna start off by ordering tubes

How do I find out which one fits it? Send a link on Amazon if you know of one that will work for this unit

i’ll try to salvage the factory wheels, and I do have another new tire, I’ll order two new tubes and give it a shot

Cenipar 20x8.00-8'' Inner Tubes,Tire Replacement Inner Tubes for Heavy Duty Cart,Such as Trunk, Tractor, Garden Carts,Golf Cart, Mowers, with TR13 Straight Valve Stem,Pack of 2 https://a.co/d/7SsiJB7

My tire: 16x7.5-8

this one: 20x8-8

I am assuming this one will work for my application?

Yes foaming tires is a real option
Doing it with great stuff canned foam is NOT a real option.
You need to have it professionally done.
It has to be a 2 part foam that is minimal expanding and cures without air.
And it is much heavier than normal 1 part expanding foam.

 

[North Idaho Wolfman]

Put tubes in it, and put tire sealer in the tube as a back up if your worried about it.

 

[Russell King]

Anyone READ the label ???

Lists all sorts of SLOW SPEED uses THEN specifically says ...'Use only as an emergency fix for light duty high speed tires'.

Hmm...
so... if I can ONLY use for temp fix, fast tires WHY the chart of NHS uses ?????

OK, clean tires and rims really,really well, install tubes, max out air to rating on tire sidewall.
If you decide to stay tubeless, use a good 'rim.bead sealer' and +5PSI air.

Read it this way…
If you put this in a high speed light duty tire it is only an emergency fix and can cause problems.

In slow speed tires use it as a permanent solution.

It was done by relatively large tire dealer that deals with everything up to including large farm tractors, and heavy construction equipment.

this particular place fills tires once a week and you have to leave them there for a day or two because they need to cure before you can move them.

Been there/done that!

I created my own issues when new by running over a coop frame with lots of nails and then walking off repeatedly after rim was compromised doing my first major loader project. Lot's of people have great success with foam but I was looking at cost and timing to get back up so I tubed both & check the pressures regularly - keep up at max. No issues afterward for 2+ years, but foam is my next step.

My size tubes were hard to find & $$ (non @ TSC etc. ) I used justubes.com

edit - I'm sure you can reuse the rims - I messed mine up badly moving on rocky ground to get level - not my brightest moment & had to sledge / sand a few spots

Yes I hear you -

I did order those tubes from amazon in a previous post, and I'll salvage the factory rims

Then if it keeps giving trouble, then I escalate (go the foam route)

R4's aren't all that heavy duty. Between those lugs the tire wall is very thin!

 

[Tractor Gal]

After reading this thread, an idea popped into my head. How about Slime? I have used that on one front BX tire and didn't have further problem. Slime is available everywhere and is not expensive. Might be worth a try.
