Hi do anyone run tyre sealants in there tyres to prevent punctures,if so which ones?
On our Jeep we got 34k out of the rear tyres which for such a heavy vehicle was impressive.We used to have a Passat Executive Style Estate 2L 140TDi which had Continental 5P 235/40Y18 which had the fluid inside. I never had a puncture, but the tyres ram noticeably warm and had to be replaced at 22000 when we were on holiday in France.
By comparison I had a Xantia 2L HDI estate in 96. I didn't know the garage swapped the tyres round at each service but I got 72K out of one set!
On cars and trailer I agree with you. In case of MTBs the sealant helps keep tire airtight plus instantly seals small punctures from likes of thorns.Tyre sealants do NOT prevent punctures, what they do do is temporarily seal up any puncture. That to my mind is dangerous because if there is a hole in the tyre I would want it properly repaired with a mushroom plug rather than (unknowingly) rely on a plug of sealant that could become dislodged at any time because there is no "head" to prevent it.
Tyre strings are a useful addition to your toolkit - but you need to practice on an old tyre before you need to use them for real https://www.tyrebaydirect.com/product/tyre-string-repair-kit/On cars and trailer I agree with you.

I prefer full size spare for car as space savers only good for 80kmhrs and 500kms due to sticking rubber. Use to do lot of 700km trips after work when there was no option to fix puncture that night, with fullsize spare could complete trip at normal speeds. Still worth carrying puncture repair in can as backup.
What do you mean MTB?On cars and trailer I agree with you. In case of MTBs the sealant helps keep tire airtight plus instantly seals small punctures from likes of thorns.

I think it is because of the extra time needed to repair the puncture as the sealant will probably need to be washed out first and they probably cannot dispose of that water down the nearest drain. Also the tyre may need to be re-balanced?Apart from the above mentioned reasons why I converted my recent cars to space savers the main one is that many British tyre depots will not repair a tyre with sealant in it. They quote Health and Safety or Environmental Protection laws as their reasons. Yet Continental issue guidance procedures for repairing tyres where puncture sealant has been used.
So you may have a perfectly repairable tyre but then faced with buying a new tyre because the depot will not repair it because you have used sealant. On some 4WD such as my Subarus I would have potentially faced having all four tyres replaced as the four tyres had to be maintained within 1mm tread depth. In the case of the Scoobies I fitted a full size spare even though it would not fit perfectly in the wheel well and caused the load area floor to not sit flat.
Don’t tyres always.get rebalanced after a puncture repair. If not immediately as part of the repair but then shortly afterwards?I think it is because of the extra time needed to repair the puncture as the sealant will probably need to be washed out first and they probably cannot dispose of that water down the nearest drain.

I have heard of people using tyre strings quite successfully, but I have never seen the kit so no any idea how it would be used.
I’ve always had them rebalanced after a repair as the tyre has been removed a plug added and the tyre may not go into exactly the same place on the rim. It’s good practice.
It should be standard practice, becasue if the tyre has to be removed to make the repair, in many cases any of the balancing weights have to be removed, and as OC above points out the carcase may not go back on the wheel in the same place.
Whenever the tyre is removed from the wheel for whatever reason it is good practice, mandatory in my book to have a full rebalance. Otherwise without question there will be an imbalance
