Exmark metro 36 front tires loose bead often

[slash5bmw]

I had to use a racketing tie down a few times to get air back into the front of these wheels. The tires don't look dry rotted but there is some rust around the rim. One of the grease fitting broke on one of the wheels but I can replace that. I like have pneumatic wheels but this is become a burden and I'd rather not stick little inner tubes in the wheels.
Should I wire brush the rims and repaint? Replace the front wheels? Put the slime in the front wheels?

Any recommendations?

Thx.

Yes, yes, no yes
Remove tyres
wire brush SMOOTH & clean or sand blast back to bare metal & do a POR15 treatment
Do not powder coat
When the wheels are dry and the paint is hard refit the tyres
Do not put any goo into the tyres
Run them at 20 psi

Perfect! I can do that. What do you think about spraying a rust-oleum paint or a basic white paint on top of the por15 to lesson the break down with the suns uv rays.

Thanks,

I do see the Sun UVs getting inside the tires easily; unless, you going keep running with tire beads off the rims.

And that POR 15 needs to rinsed off after it done its job.

They actually market a range of both spraying enamel & brushing enamel under the POR 15 brand which is very hard but you can use any normal top coat paint .
I use brushing enamel over it on vintage motorcycles

I’ve used this bead sealer with great success, over the last 15 years. Clean the rim extremely well and apply sealer to both beads not rims after tire has been installed, pump up the tire. In my opinion a great product. https://www.autozone.com/sealants-g.../x-tra-seal-tire-bead-sealer-32-oz/576770_0_0

Guys,

I greatly appreciate all the feed back. I will pull the tires, wire blush the rims, paint with pot15, lightly paint with white rust-oleum spray paint and apply bead sealer to the tires.

StarTech, if you think the white spray paint is detrimental, I'll skip that step.

BTW, I thought the grease fitting broke off but it just fell out. Doesn't anyone know the thread size? I think it's SAE not metric. I am going to swing by HF and pick up a variety 50 pack of grease fittings.

Check the grease nipple hole
Some are pressed in and a lot the hole strips the thread out

I removed the grease fitting from the other wheel and was able to screw it into the wheel that lost the fitting. I was lucky that it wasn't stripped.

There are 45 degree grease fittings in this HF package that will fit perfectly in the rims.​
