New Tire Installed...help!
 

Hey all,

About a month ago, I decided to go with Continental DWS tires. I got them ordered from Tire Rack and installed them. Fast forward a month, my passenger side front tire keeps losing air. I would fill it up to 40psi and leave it in the garage. 24 hours later, it would be at 12psi. I took it to a tire shop and they lifted the car and sprayed the tire to look for bubbles. They did not see any air leaks or see any nails or anything in the tire.

I'm at a lost. The tire keeps losing air and they can't seem to find any issues with it. I love the tires and ride. If there was an issue with the install, I don't understand why it would be ifne for a month and then start leaking.

Any ideas? Since the shop didn't take the tires off, I'm having someone else take the tires off tomorrow to take a look, but I was wondering if anyone might have experienced the same thing.

Thanks.

Go to another shop. If you lose that much air in 24h hours there will be a visible leak. Make sure you inspect the wheel too for cracks and maybe change out the tire valve stem.

+1 for rim fracture. Happened twice to me on my GL. Check right where the spoke meets the wheel.

if its hard to find, get a tub of water, filled about 6-8" high and rotate the wheel through it after inflating and look for the air bubbles

sounds like they're incompetent

Wheel crack

HOLY CRAP!

Wheel crack? I'll have to take a look. I didn't run over anything. Dang. I really hope it's not the rims.

Kinda had this happen once. For me my valve stem/tpms got loose. There's a little nut around the valve stem that I ended up having to tighten down. Turns out I just barely touched a curb and knocked it outta whack.

It's a loose TPMS - happened to my multiple times with OEM & aftermarket sensors. Have them check there with a water bath.

All,

I took the tires off today and it turns out there's a fracture on the back side of the rim.

I'm so pissed.

Anyone know where to get cheap rims? I only need 1.

Thanks.

Sorry to hear that

I guess its so bad that a weld is no good? Try eBay .

If you do not plan on tracking, and depending on where the crack is, it can safely be fixed. You are in VA, guessing around the DC Metro area. I will have to remember where I took mine to. I had a crack as well, cost me around $100. the crack was on the inside lip, they cut the area out, and welded new metal in place (you cannot just weld a crack). The shop was located near Annapolis, although I am sure there is probably a location closer to you (was not a chain, but there are a number of similar shops around)

Thanks.
I did hear there's a way to fix it without replacing it. I'm actually in central VA. DC's a lil far for me (2hours). I'll see if I can find someone around here.

It's not bad. Just a fracture that must go in deep for air to come out.
Picture attached.

how did the tire shop miss that the first time though....

It's a crap shop. But it was the only Conti dealer in town.

I initially thought the tire would have to be replaced under warranty, not thinking it was the rim.

I called the local Benz dealer (which is also crap) and they want the numbers off the rims. Guh.

That is exactly the same as the damage to my rim, same length as well by the looks of it.

Here is mine.

Damn...identical.

I wonder if it's a recall. Probably not. Dealer just quoted me $1K for the rims.

I would prefer buying another rim... peace of mind

Yeah that's what I meant by rim cracked, it's happening to me almost every month in nyc... lol

I agree - if why not have an OEM product on your AMG? More peace of mind at 120 on the highway. Or 60 for that matter.

Mine cracked right there too. I had it fixed. Good as new...don't waste your money buying a new one.

LOL Guilty....you certainly seem like you can afford it.

I feel for you NY/NJ folks.

I hear ya. I tried to find someone local but didn't really want to risk it since there wasn't a good source for research.

I initially called a dealer 1 hour away since that's where I purchased the vehicle. They were the ones that quoted me $1K after I gave them my VIN.

I cut out of work early and went to the local dealer who took the wheel off and looked up the number and quoted me $544 for a replacement rim.

All in all, I figured less than $600 for a new rim with install and tax isn't too bad vs. fixing the old rims by someone I have no info on.

Exact same thing on my car as well, except I know the offending pothole.

Now I'm glad I bought the wheel/tire/glass/keybob insurance. $2k for 5 years seemed high, but maybe not for us NY/NJ folk.
