Runflat with a nail

Wheres Me Jumper?

Hi Guys!

Can somebody advise me please.

Took my car out for a drive. Hadnt drived her since Wed. 10 to 15 mins in and the tyre pressure monitor indicated loss of pressure.
Pullled into garage and gave it a few pounds of pressure. While doing this I noticed a nailhead in said tyre.
Drove home. Very short distance.
Car now parked up. Do not need it as I can use partners.

Driving on runflats, so I have no spare!

Will tyre stay inflated overnight as it is?

I don't know and no one can tell you.
Your best bet is to look in the morning.
Then report back to us

Just plan for it being flat, or as flat as a runflat will go. Surely a neighbour or someone will have a 12v compressor in their car you can borrow to pump it back up and get you to a garage.
Or give me a shout and I'll come fix it :pac:

Thanx guys! i realise it's a kinda of wait 'n see scenario.

BTW i sprayed the nailhead with some soapy water and its bubbling away.
I dont have a 12v compressor but might nip into Halfords in the morning in any case.
I do have a can of Holts Tyreweld which i was considering using.

The 2 rear tyres are kinda bald, so I was planning on changing both of them (front are pretty good), but not just yet. Wondering how long that Tyreweld stuff might last as I dont drive very much and i can always use the wifes car if needed in emergency.

Drive on it as little as possible. Farther you drive on it flat, more chance of damage inside.

Happened to me a while back, back wheel was flat but driven on for a few days. When I noticed the puncture and went to have it repaired, found the inside of the tire shredded, new tire needed. Expensive lesson.

point taken. done a bit of online research and it seems runflats will not fully deflate even with loss of pressure, as the sidewalls should hold firm.

i'll be driving very slowly only around town and check and reinflate on regular basis.
at least this buys me some time to buy new pair online as i originally intended.

we'll see in the morning. fingers crossed ....

Why not go to puncture repair place and have it checked out for possible repair?
If it is on flat portion perhaps it can be plugged.

well just to update, the tyre is still holding. checked the pressure and it hasn't dropped much at all.
that's perfect as i now have time to get 2 new ones without panicking.

i know they're more expensive but those runflats do what they say on the tin. apparently they can be driven 50 miles at 50mph before you need to get to your garage.
i was considering getting regular tyres and buying a 12v compressor and maybe a tyre plugging kit, but after this i deffo think runflats are worth the extra.

I'd a nail in a tyre before and while it didn't lose air when standing it did lose it after I drove. So check the air pressure before you set off as you might stop in a position that puts pressure on the nail and lets the air out.

A cheap 12V compressor is handy for keeping the tyres to the correct pressure, especially since "free" air is gone from most petrol stations.

Ok i've driven approx 10 miles since pressure warning sensor kicked in, and the tyre is still holding its' own. Looking at it you wouldn't even notice it was punctured, which leads me to wonder just how many day/weeks was that nail in there before warning light let me know pressure was down?

Anyhow I've ordered 2 new tyres online this morning. Local garage will fit them. Looks like they are being shipped from Germany, so God knows how long it'll take.

here's an update on my noflat runflat.

i've done about 50 miles since i first noticed the nail. all local journeys. none above 40 mph. the tyre looks grand. the cars' tyre pressure monitor has not detected any loss in pressure, as i keep it "topped-up".

my tyres have left the warehouse and delivery is expected on Wed.
i am a total convert.

You're hardly "running flat" if you are checking the pressure and keeping it topped up. I have done that with normal tyres with no adverse effects numerous times. My understanding of "run flats" is they allow you continue your journey to a repair shop without re-inflating.

Agreed. I've only had to top it up once since it first lost pressure.

I think the fact that you’re able to drive around with a nail in the tyre (and it staying inflated) is nothing to do with the fact that they’re runflats. I’ve done this many times with regular tyres. The nail is just embedded in such a way that it’s sealing the hole it made. You topped up the bit of air that was lost when it went in.

You seem to have new tyres on the way. You haven’t mentioned that you have any other reason to buy tyres other than the nail in one. Assuming the thread is fine, and the nail is in the threaded part of the tyre, chanced are you could get it plugged for less about a tenner, and it would be perfect.

Sorry, but unless you’re omitting some details, I don’t think runflats saved you here, and I don’t think you need new tyres.

Tyres were mentioned to be well worn out

SIlly, reckless behaviour to save a few euro.

At least the OP knows that they have a nail and are monitoring it. I had a nail in a non run flat and had to keep topping it up over a weekend before I could get to a repair place, didn't do any harm and because I have a space saver spare was the least dangerous option.

But I can guarantee that there are thousands of cars on the road with nails in their tyres that the operators know nothing about, and some could be in for a long time.

I see numerous cars daily with under inflated tyres if not completely flat toddling along without a care in the world.

I'm not even sure why run flats are mentioned here. And I don't understand why you didn't plug it immediately and carry on your way at whatever speed and distance you like.

driving around with under inflated tyres is very dangerous, as you are more likely to have a blowout.

anyone who's ever had a blowout at high speed knows just how dangerous this is!

UPDATE

Got me tyres last week. The local garage fitted and balanced both wheels for 20 Euro total.
By ordering online I managed to get 2 top of the range tyres for the same price as cheap low-end ones stocked around here.
Some of the brands they were selling I had never heard of before tbh. In fact, the local guy didn't even stock the ones I got as he said there was no demand for "expensive" tyres.

so far, very quiet. good grip on both wet and dry. not sure about fuel efficiency, or longevity yet. time will tell.

all in all very pleased.


BTW i did almost 200 (slow) miles on a worn runflat with a dirty big nail stuck in it, with only 1 top up of air!

What tyres did you buy OP?
