Title says it all really. 2 days before we start our journey home and I pick up a slow puncture in the near side front tyre . I have 235/40 R19 Pirelli P7s fitted (factory fit from new) and it’s not easy to get replacements as so few dealers stock that size. Have looked the tyre over and can’t see anything in it or any obvious damage. Am thinking about using the sealant gunk to get us home without having to stop every 200 miles or so to pump the tyre back up. Has anybody used the stuff themselves and if so, how effective was it?

How much tread is left on the tyre?

 

Using a sealant, usually means the tyre cannot then be repaired, so I would be reluctant to use it. 

Norauto seem to stock a few

Tyre weld works, and you can clean it out if a tyre repair operative does not want to after they take the tyre off for you.  You take the tyre outside and clean out the rubbery mess that might or might not still be liquid.

 It does not ruin a tyre.

 

Why not go now to a Tyre Fitting centre and let them find the leak, valve, rim or puncture if water and washing up liquid does not show you where it is.

If you do not know where the leak is then tyre weld might get you home ok, but if you are missing if something is in the tyre it is not that safe really.

The tyres are coming up for replacement and was planning to do that in July after we get back. We have to drive about 900 miles in 3 x 300 mile legs to get home so was hoping that the sealant would do the trick for us. Sounds like it might though I’ll have another look at the tyre first in case I missed something.

Had two tyre incidents in France, one repaired for 20 Euros IIRC at First Stop.  Face of the guy who drove it round to the bay was a picture when he realized the steering wheel wasn't there.

 

Second was a new tyre having touched one of the sharp kerbs they have in Metz which meant a new tyre, they will only fit matching tyres so you may need 2 if you can't get one the same.

Don't waste your time with sealant and find yourself some French tyre shop who would fix the tyre. 

Sometimes those tyre sealants can cause a bad vibration on high speeds and I sincerely doubt that you want to drive home like that.

replace stock Pirelli P7 by any other brand

and before install new tires order dTPMS set

High speeds won’t be an issue as we have our caravan in tow. Anyway, I’ve done the deed now. The gunk is in and we’ve driven around in 33 degrees of heat. Checked the tyre pressure when we got back and it had increased to 3.9 bar, same as the other side (am running 2.8 cold on the front due to towing). Will check again in the morning but fingers crossed it’ll see us home. Anybody got any recommendations for new tyres. I’ve no problems with the P7s other than they’re on the expensive side

@Albourneboy - No experience of that size, but Pirelli usually prop up the "known brand" end of tyre test tables.

We had similar in Trieste, Italy in our SI Superb a number of years ago.  He opened the front left door and wondered why there's no steering wheel!

Missed Italy - maybe not everyone knows where Trieste is.
