Worn out a set of tires on my EZ Tow dolly on the edges. This would indicate low pressure ? I run them at 75 per the users manual. But looking at the EZ tow Web two places say 90 psi and two say 75 psi ????

Now I be confused.

Our manual and the tire sidewall says 90PSI.

Never saw 75PSI except in a reference to lowering the pressure when moving the dolly unloaded.

The tires are not expensive, so no problem to replace.

Safe travels

Please send some pictures to us at this address so we can see what is happening acmetowdolly@gmail.com If the tires are wearing prematurely on the edges that means one of two things. The spindle is damaged and has been moved, or the bearing castle nut needs to be adjusted, probably tightened up a wee bit. The spindle can be be moved back to neutral by a competent collision shop with a frame machine.
Is it one tire or both? Inside or outside edges? Please advise and send pictures. We keep these tires in stock ready to ship.

Thanks

Acmedolly,

What is the correct pressure ??? Your Web site shows two pressures ? "Owners Manual" says 75 psi but "How to use" says inflate to 90 psi.

My manual states 90 psi. I bought mine last August.

I have always run them at 75 psi as I thought that was correct. They had gotten lower than that on this trip and I didn't realize that !!! My fault, didn't check them because they looked fine. One was down to 50 psi and the other 60 psi which explains the wear.

Here is a quote from EZ Tows online Owner Manual ???

Never tow with a bumper ball, use a properly designed hitch system. Make certain that the coupler is securely tightened . There should be no play at all..

Again both these quotes are direct from their webpage ???

I have inflated both tires to 90 psi now, but would still like to know what is correct. Too bad the EZ tow guy didn't answer the question when he asked for picture. Again, it would appear that my poor maintenance cause the unusual wear of the tires. At close to $100 per tire I just need to make sure I'm not the problem !!!

You can call them and ask, they have been very helpful when I have called. Please post any findings.

I hope to add TPMS to my dolly this season.

My apologies, we recommend 75 PSI which is how they ship from the factory now. However some people find that 85 works better. 90 PSI is the maximum. From anecdotal information it seems the tires last longer at 75. If they are not balanced be sure to do so, they will last longer.

Well, that's clear as mud.

Yikes, I have been running mine at 90 psi. Will correct this year.

How about saying it depends on the load being carried just like weighing your RV and then setting the tire pressures accordingly.

Scarab0088 · 03-24-2015, 10:47 AM

90PSI is the max (with tires rated at 1,650lb each - I think) so the load placed on the dolly dictates the PSI.

Best luck

vettenuts · 03-25-2015, 05:57 AM

At 1,650 lb each, that would be 3,300 lb total. That is close to the curb weight of my Malibu so I think the lower pressure should be fine in my case.

KevanRO · 06-29-2015, 04:58 PM

Thanks to all above. I had not checked my pressure(s) yet this year- When I had purchased my EZE Tow Dolly last fall, the only numbers I remember was the 90 PSI (deflate to 25 if pulling empty) I just invested in a Tire Minder A1A TPMS system, and will make sure my dolly tires are set to 75 PSI loaded...
