Fix a flat tire fast - what I learned could help you a lot.

Our EV6 FE had a sudden loss of pressure and flat tire this last weekend on Sunday night. And to make it worse, the vehicle was being used for traveling to work, 70 miles from our home. Careful inspection of the tire (passenger rear) revealed a sharp object in the middle of the tread.
In an act of preparedness, I had the tire mobility kit, the instructions AND I purchased a tire plug kit to use. Both were in the vehicle.

WHAT I LEARNED

First off, if you do not need the car and have a way home, you can have it towed to a repair shop. But Discount Tires (AKA America's Tires in some parts) does not have a drop off system. So you will still have to go back there to initiate service if the vehicle is locked. Your tire dealer may be this way too.

Secondly, the EV6 has no jack and it is a heavy vehicle. You can purchase a small hydraulic jack to lift the car, but then there may be no space to place a jack stand if you take the tire/wheel off the car. AND it is unwise to have any vehicle held by only a hydraulic jack due to the potential for hydraulic failure. Small scissor jacks are not rated for EV weight.

Third, many Kia's no longer have the original tires on the vehicle. In our case, our rubber is Michelin Crossclimate 2 which we love. This tire in 20 inch is seldom in stock so unless your tire can be repaired, you may have a delay in installation of a new tire. In this case, it may be wise to keep one or two of your old tires to use as an emergency mount until an exact replacement for your second set is ready to install if your flat tire cannot be repaired.

FORTH, is that tires are tough stuff. If you think you can remove a foreign object from the tread and insert a reaming tool and then a tire plug all while lying on the ground, think again. You don't have the leverage and the tire has to be inflated, otherwise you just push the rubber into the wheel. Plus, you may make the tire damage worse or prevent the repair shop from working on your tire further.

FIFTH, the Kia tire mobility kit specifically states not to remove the foreign object. ON THE OTHER HAND, products like SLIME, say to remove the foreign object.

Sixth is that the vehicle to load adapter can be very useful if you have a flat tire. You can purchase a small air compressor and hose (a 2 gallon or three gallon does a great job) which will run from the vehicle to load adapter and rapidly inflate your flat tire. I used this method. So this can be left in the car or if you can get help from home, it can be brought out to the site of the flat tire.

Seventh is that SLIME makes a variety of products that are game changers, especially for the Kia EV's. THE SLIME RESCUE product directly connects to the valve stem of the flat tire and then you connect your compressor (including the Kia mobility compressor) to the Slime Rescue. Turn on the compressor and the SLIME is carried with the air into the tire. Once inflated, drive the tire slowly to distribute the Slime. The leak should hopefully be plugged. You can then drive to your destination and contact your tire dealer.

SUMMARY: In the event of a flat tire, use of the SLIME RESCUE with a Kia mobility Kit IMO is superior to the unknown Kia cannister product and also works even if the object that pierced your tire is no longer sticking into your tire or was removed. And the Slime Rescue product can be easily restocked in your car from Walmart, online, auto parts stores etc. The tires store had no problem removing the Slime and patching our tire.
The use of a 2-3 gallon compressor and the vehicle to load adapter can allow rapid inflation of the tire for use of Slime products with and without the valve stem in place. This size compressor is also useful in case of only partial success in slowing a tire leak using Slime or the mobility cannister in that you can inflate your tire, watch the pressure on the instrument cluster as you drive and when the pressure drops to say 29-30 PSI, quickly re-inflate the tire and head out again. How far you can go this way depends on the rate of leak, but at least you know you can get off any side road or highway this way.

FINAL REPORT: We removed the screw from the tread. We installed Slime (not rescue version) into a flat tire with the valve stem removed. We screwed back in the valve stem and inflated the tire with use of the vehicle to load adapter and a 2 gallon compressor. This sealed our puncture and we drove home the 70 mile distance arriving at 1:15AM. The next day the tire store plugged and patched our tire and the Slime was removed. I think this is a viable option for a punctured tire instead of a spare tire of any size unless of course the mounted tire was destroyed.

Yeah, but if you have a tire with insulation foam inside, tire shop technicians will really hate you because there is additional work involved in washing out the tire from slime.
Depending on foam insulation type, some can be washed and some will have to be removed completely out and disposed to garbage. Tire will still function but it will not have insulation foam.

Well actually the Michelin Cross Climate 2 tires are great on the vehicle. Far superior to the Continentals that came on the vehicle and which developed side wall bubbles. I don't know if these have any foam or not. But I also don't care if the tire shop technicians hate me or not. I buy my tires from them and if they do not provide me in advance with any caveat on flat tire repair, then its their problem.

All good points and advice. (y) Glad you were able to resolve everything.

We have AAA and I'd probably opt for a rollback tow rather than tackling a flat tire on my own anymore. We have Michelin CC2s on two of our vehicles and our EV6 will be next. Terrific tires, but like any tire, subject to road hazards. We bought ours at Costco so that's covered, but you're right, they probably won't have one in stock.

We've had other cars and trucks that did not have a spare tire. I have this DeWALT tire inflator so that I don't have to visit local gas stations to keep our tires at the proper pressure. I take it with me on trips just in case since it takes up very little room. If the puncture is small enough it can get us to somewhere safe. Otherwise, AAA is in my phone's speed dial.

...Small scissor jacks are not rated for EV weight....
I’ve noticed there are plenty of scissor jacks that work on an EV6. And they store in the back cubby hole along with the EV6 air compressor and a couple of rubber chocks.

Keep on rolling,

Last June I lost air in my left rear tire. It started with a flat tire sound but go no warning light nor did the tire look flat after about an hour of driving around the noise sound changed and low tire pressure light come on sure enough the tire was going flat. I had to finish driving to drop something off . I used the tire kit that KIA included with the car and inflated the tire enough to drive. went to a serivce station and inflated it more. 5 days later I took it to the dealer . they checked out the tire couldn't find anything in the tire. The tire was maintaining pressure . Here it is Oct 2nd and the tire continues to maintain pressure. They Dealer said keep driving as normal as long as the tire pressure holds ( I lease btw) so the white stuff does work that is in the kit. I do need to go buy a new bottle still.

Slime's website - We do not recommend installing Slime sealant into quiet tires. The tread area of a quiet tire is coated with a layer of foam. If the sealant is installed, it will be instantly absorbed into the foam, rendering it unable to reach and treat the puncture. The sealant will also likely result in tire vibrations. Additionally, there is no way to remove the sealant from the foam and the tire will likely need to be replaced.

I guess the sealant will still work in the OE EV6 tires which have the foam inserts or KIA wouldn't have included it, but headaches could ensue.

I posted this video on this thread discussing if foam inserts are really worth it. Unfortunately the CC2 foam video "comparison" isn't really apples-to-apples since they're simply adding foam to a conventional tire. Ideally they should have tested an EV-rated tire, with and without the foam insert. Still interesting.

Wife had a nail in the tire when in town. She called me and I went to meet her at the car park of the food store. I already had purchased multiple items for this probability that were in the car. We found a nail in it, but it looked like the leak was small and it had been going down very slow over days, so we pumped up the tire and with me following drove all the way home which is a 30km trip. There is used the kit that I put in the car to remove the tire, plug the hole and put it back on. We then went ahead to order a spare rim (which we were going to do anyway, but never got around to it) and ordered 2 new tires. And yes, it was a fair amount of money. The Rim was AUS $1,600,- and the tires were another AUS $600,- each. It's a fair amount of money spend, but we are keeping the car for the long term. Now we have a spare in the garage with one of the old tires (the one without the repair) mounted on the new rim, while the other repaired one is another spare. Should we go for longer distance travel, I will throw the spare in the back.
Now the items I have purchased ...and yes from eBay all have worked out great.

1) This Vevor kit worked surprisingly well. VEVOR 3/5Ton 12V Electric Hydraulic Floor Jack Car Lift & Impact Wrench Kit | eBay
With the remote, you can actually lay under the car while moving the hydraulic/electric lift in the proper position as it comes up. The car electric gun will undue and remove the nuts, but be aware, it spins up and then engages a clutch violently, which makes behave like an impact gun...but more violent. So I do not recommend it for putting the nuts back on and tightening...do that by hand.
2) I used this portable wrench to put the tire back on: 17 19 21 23mm Portable rapid Cross L Wheel brace car Tyre Nut Wrench Spanner | eBay
3) and this was used to repair the tire: 67PCS Tyre Puncture Repair Recovery Kit Heavy Duty 4WD Offroad Plugs Tubeless | eBay

The link you've posted is to a Continental Tire site overseas. Unfortunately (or some would argue fortunately) the Conti's on the North American EV6s don't have "self sealing"/"run flat" technology.


There are two types of "run flat" tires and both have symbols on the sidewall. One actually says "Run Flat" or has something that looks like a snail (or a combination) and the other has an "RSC" in a circle.

IIRC the only run flats available for the EV6 are the Goodyear Eagle Sport All Season "Run on Flat" tires.

There are a few threads on the topic. Here's one...
