R 14 tires on a MX6000, Problem with vibration

[jyoutz]

Jeff it is almost like a shaking in the rear. Both rear tires seem to be running true as it almost feels like loose wheel nuts but it is not.The left outside mirror doesn't vibrate it is more of a shaking. I am considering having the dealer take out the juice in the rear tires if that would help.

Sure have never heard of liquid tire ballast doing what you describe.

I have 775# of RimGuard in each of my rear R1 tires. At a certain speed - going down my gravel driveway - there will be a minor vibration in my canopy. On the asphalt county road - smooooth.

Mine don’t vibrate on my very short dirt road trips around the corner.

Are your rear tires loaded?

 

[Midniteoyl]

It is the lug tread on the R14 tires which is the primary cause of the vibration you feel.

No..

Are your rear tires loaded?

Yes.

Are you sure it’s coming out of four wheel drive properly ? Mine will vibrate like you described on pavement but only if it’s locked in four wheel drive, no noticeable vibration in two wheel drive.

It definitely is not in 4wd., I did lower the air pressure on rears some and that did help so it isn't to bad now.

I don't know what tire pressure you are running, you did say you lowered it some,
that weight tractor with 17.5-24's doesn't need much pressure at all.
At 12 psi and 15 mph each tire is rated over 3000 pounds or 6000 pounds for the pair.
This is the pressure load chart from Goodyear.

Thanks, as I did lower them to 15-16 lbs.
Thanks for that info. I did lower the pressure on my B2650 to around 13 lbs. on R4 tires back along and the rim guard started to leak out on one tire around the rim, so I had to put more pressure back in.
