Default Motor Oil on Bead for Tire Mount?

I went to a tire shop to get all new tires and they used motor oil on the bead to mount them. Is this acceptable? Everywhere I've read it's recommended to use soapy water or purchase special lubricant.

Depends, you selling the car soon or are you hoping the tires last a few years/40K miles?

Liquid dish/hand soap or "special tire mounting lube" (not much different than liquid soap.......) does not attack the materials n a tire.
Will motor oil kill the materials?
No clue.
Would I use it long term?
Nope.

Your choice. Maybe search on the net to see what others use/recommend.

Definitely not selling any time soon and yes, looking to get the most mileage out of these tires. I'm trying to figure out if I need to go to a different place and have them re-mount the tires and clean off the oil. I've searched and couldn't fine anything that's why I'm asking here.

​​​​​​​Second part to my question, since it isn't acceptable or safe, can I take it to a better shop within 24-48 hours and have them take off the tires, clean them, and mount correctly, or is there enough damage already that it will reduce the life of the tire?

Most likely, the damage has already been done. Oil is going to penetrate into the rubber within minutes. It may or may not affect the life of the tire, I think that depends on just how much oil was used. If it was just a trace amount (like if it was wiped on with a rag), then I wouldn't sweat it too much. I would really not bother with it unless they used a ****load of oil.

If you want the peace of mind you can take them to another shop and have them removed, SAFELY cleaned, and reinstalled correctly. You should avoid using any other chemicals (lacquer thinner, alcohol, brake cleaner, etc) on the tire aside from soap/detergent and water.

The oil was dripping thick down my rims and tires. There was a lot and certainly not just a thin layer applied with a rag. All the rims and tires needed to be cleaned after they were mounted.

Would Simple Green be a good idea to clean the tires, or just soapy water?

The tires were installed around 530pm Sunday, so if I get it cleaned within 24 hours, you're saying the oil that has absorbed into the rubber has already done damage?

Was this a hillbilly tire shop? The tires will be sliding on the wheels for the next few years. You will need to get them rebalanced every month or two.

Dismount the tires, clean the oil off with soapy water. I doubt that there will be any damage. If you squeeze a new tire with enough force, you can actually see some oil come out.

Not hillbillies, Africans that barely speak English.

So I dropped in another shop that came highly recommended, they're cleaning and remounting properly. BUT, lo and behold, these idiots at the original shop didn't use a torque stick, so one of my bolts was cross-threaded and now I have to spend money to get THAT replaced.

I called the owner of the African shop and he refused to do anything, so I told him I'll see him in court for all the repair costs. He called me back several hours later and said to bring the receipt for repairs and was suddenly very nice. We'll see if he actually reimburses me. This is exactly why I wanted to do this all myself, torque wrench in hand, but these wheels will not take a new tire with spoons, way too tight of a fit.
