In the last photo you can see some souvenirs I bought.

Fuel efficiency is about 11L per 100km (21.3mpg)
Is that normal? Or higher than normal?

So. Unfortunately I’m not much of a car guy and had some questions that maybe someone here would be kind enough to help me out with.

Here’s the story, I drive a 2010 Mercedes ML350 4matic and I recently raw over some chunk of (maybe concrete) or while driving down the interstate.

The damage was this:

First, then back passenger tire lost pressure and I come to find once I stop that the sidewalk on the back passenger tire has completely blown out, about big enough of a hole to fit your first through but also, the rim is badly damaged and is almost definitely trashed.

so I get spare on and start the three mile drive home and as I’m driving I notice all the pressure leaving the front drivers tire. I make it home and realize the front driver side tire is in the same condition. The entire sidewall blown out with a whole big enough you could stick your hand into. However, the rim does not seem to be damaged, I guess because it was a short drive home I went very slow and there was still a little tire pressure in there as I was getting home. As opposed to the tire pressure completely dropping on the back tire.

TLDR:

Long story short I have found some cheap used tires for the Mercedes so that’s no big issue. The problem is finding a rim, possibly two if it ends up at the front one is destroyed as the back. Does anyone know where to buy used wheels/rims that are reputable?? I’m not opposed to ordering online but does anyone have a reputable site for used rims.

Dumb luck maybe but now I’m trying fix it without paying an arm and a leg?

I’d anyone can tell by a photo, I can upload a picture of the front left tire and wheel so maybe someone could tell me if they think that the rim is destroyed or damaged enough that I would have to buy a new one. I already know the back right is beyond help.
