Cool. That's my thought. Here's hoping it'll make it back to the warehouse. And it's not too badly damaged.

Nothing like finding your way around a car due to your own mistakes

isthenew I could not find any information stamped on any of the replacement rims, other than the words "Chrome Tech." As such I didn't bother looking at the OEM.

In any case, I mounted the 40mm rim to a front hub. It clears the outer tie rod end by like 1 mm. And I'm not comfortable with that. So I switched, placing the 60mm on front. It was clear of the tie rod end. But the 40mm rims won't mount on the back. They don't clear the car.

So I'm done w/these. Gonna sell them (and my 60mm bolts) and buy 2 new tires for the OEM rims.

Oh, and when I drive now, I'm getting a fun and exciting grind from my left rear hub; the one where I put the 60mm bolt into the 40mm rim and I tightened into things that never should experience those bolts. Here's hoping it's not too difficult a repair....

Thanks for all the help.

tusabes there should be model numbers stamped into the back side of those rims under all the brake dust and corrosion

I had The same problem , discovering two rims I bought from the same car were 1 inch different, they sent me a front and rear instead of two rears !!

Yeah. Holy crap. I started digging into this from your suggestions. There's a lot to this.

The hole diameters are the same. I wondered about this, thinking maybe the 40mm bolt was getting stuck in the shaft, not going all the way in, and that's why the bolt wouldn't work. So I put the 40mm bolt in from the back side. It went through and I measured how much of the shaft was left. It's going all the way in. ...I also put the 60mm in from the inside as well. Just to see if there was a noticeable difference in diameter.

Now that I'm looking from the backside, it looks like these are manufactured differently.

The first rim I mounted was the thicker one. It went on perfect with the 60mm bolt. I'm really liking the look. And the other rim, I switched it from 60mm to 40mm and it mounted perfect. If there's a way, I'd like to keep these. But, this is my hurricane car. If they're unsafe, I can sell them and put 2 new tires on my OEM rims.

You do have to check your rims however!!! There should be a size (diameter and width) and ET marking on the back somewhere. If they're MB rims, there will also be a part number. Let us know what you have (check all four).
Appreciate it. These 4 rims are paired. The only difference seems to be that depth for the shank, pushing the rim and tire further away from the hub on 1 pair. Which seems weird to me. Because if I were to change that, I'd get different sized rims and go staggered sizes. Because it's not like I'll be rotating these tires now that they're paired.

I'll see if I can find any sizes and part numbers when I get back to the warehouse tomorrow.

There is no spare with these. I have my 5 original rims, 3 still with great tires. I'll keep one of those as a spare.
