I may be wrong, but what I have been told was when you use the spray foam then the tyre is rendered unusable afterwards. Meaning it goes in the bin.
I am sure someone could clarify.
Thats correct, when my Merc had a nail in the tyre, the garage broke my wheel lock nut key whislt taking it off. They put in a Rats Tail in situ. Key cost me £36.00 from the stealers :xSmartbear said:weegeoff said:If you are going to use a kit that uses plugs you WILL need a jack and a wheel brace.
Why do you need a wheel brace? I’ve fixed punctures with the wheel in situ

Run flat tyres have to be the biggest single con going in recent years. A conspiracy between a car manufacturer and a tyre company at a huge cost to the consumer. What a complete and utter rip off. The tyres themselves are outrageously expensive and not fit for purpose, hence cracked and broken alloy wheels on a huge and very expensive scale. Ride comfort is a totally different story and on a very different level to 'normal' tyres. There simply are no real valid benefits whatsoever to these tyres and a whole host of reasons why people change to normal/standard tyres at the earliest possible convenience and actually enjoy stress free, much cheaper, less hindrance, comfortable everyday motoring.

I have to agree about the run flats on the Z4 they are utter crap and I changed them almost as soon as I purchased the car but I do think the tech has moved on. My 2016 F20 1 series came with 17" alloys and run flats from the factory and they were perfectly fine in terms of ride handling etc. It was pretty much acceptable whereas on the Z4 it isn't, although I wonder how much more quieter and better ride / handling the F20 would have had if it had normal tyres.

Whilst I fully agree with you from the enthusiastic driver point of view, I have to say that, living in deepest, darkest Norfolk, I do get a degree of comfort in knowing that, if my wife gets a puncture while out at night on her own, she can at least drive her car to somewhere safe rather than being stuck in the pitch black countryside, with all the associated issues with that scenario.
So, on her 220d convertible there is a 'real valid benefit', and the runflats stay! On my Z however, they are gone, never to return.
You're choosing the four small patches of 'rubber' that keep you on this side of the afterlife so buy the best - Michelin Pilot sport 4 or Pilot sport 4S.
They have the best reviews and are fitted as OEM by many hi performance manufacturers.
Buying the best does not make you a 'snob' it just means that your life, the lives of those you take in the car and those around you are precious, you will find people running cheaper tyres but spending more on a set of downpipes than a set of these will cost you.
What are your priorities?

So to say that the Michelin SP is the 'best' is at least one dimensional and not accurate. It is a very good tyre but to say its the best is simplistic..IMHO!!
If you read in further detail and seperate absolute performance from 'usability' quite often for Johnny Average ( where most of us exist), tyres that give greater feedback score better as they don't bite the driver when they start to let go...hurtling arounnd a track repetively is great for dissecting tyre performance but is not as much help as when a bend tightens up and you want to know how close or not you are to the edge..
In the final (for me) analysis, most drivers would be well within their limits with any of the (on average top 5 or 6 placements) under any circumstances they would encounter or if they were pressed could cope with.
Most people have a misguided view of their own skill / competence level..I had a brutal re-orientation when I climbed into a fast/fragile/aerobatic aircraft after plodding around in more pedestrian devices..couldn't wait to get back to those and never flew in an aerobatic aircraft again..others could lap it up..serveral have died trying to lap it up!

While I appreciate the effort you put into that reply, you completely missed the point. I was pointing out that there's a lot of people here who recommend the likes of the Uniroyal Rainsport tyres. You posted a load of links to tests that all say that premium tyres work best, which reinforces my point. I didn't claim that the Michelin Pilot Sport 4S is better than the Continental.
Looking at the information you found I'm going to discount that first link to "tiresvote" because it looks like absolute garbage. It bases a lot of the weighting on spurious Autobild tyre reviews. The only Autobild tyre test that matters for 2019 was the summer tyre test and Michelin won this test with the MP4S. (https://www.tyrereviews.co.uk/Article/2019-Auto-Bild-Summer-Tyre-Test.htm).
The link to the TyreReviews UHP summer test is great, AutoBild and TyreReviews are really the only two worthwhile sources of information about tyres. The Eagle F1 came out on top there because of the subjective handling scores. Again, the Eagle F1 is a premium expensive tyre comparable to the MPS4S. The MPS4S came a close second and did win the wet and dry braking category.
The rest of the links compare the MPS4, which is the less capable and cheaper version of the MPS4S.
Plenty of people use the old "I don't drive fast so I don't need good tyres" or "I don't drive to the vehicle limits" excuse. That's complete crap. Even when driving like a pensioner you may need a little extra grip on a misjudged corner or for an emergency stop.

I’ve lost the will to live on this one..my point was relative to mcbutler who implied that only the Michelin tyre was ‘acceptable’ to a possible newbie who I assume was asking for some balanced advice..it’s fine to have an opinion what I don’t like is when someone presents a supposition or opinion as a definitive fact...I think people should be clear when it’s an opinion vs a fact..
I’ve spent a lifetime always buying the best afaik when it comes to safety related matters..upsetting my wife/shareholders/banks in my pursuit of a focus on safety...with no compromise..people who know me will know I always have a back up to my back up..
Some people have a view that only the best in their perception is the minimum acceptable .. others are driven by cost, others try to balance the two..
As usual people usually believe their purchasing decisions are the best and insist others should follow..
I think some of us are trying to address that confirmation bias by highlighting the fact that many people do have options depending on their priorities..
The criteria I always use is the following scenario
I’m in a coroners court facing the family of the bereaved who have died in an accident that you had some involvement..
When the coroner asks you ‘is there anything that you could have done to avoid this death?’
I need to have a clear conscience..
So to come back to your point..
I’d struggle to say that by someone using a mid tier tyre they put their life and others in jeopardy...
If they said that they ran their tyres down to legal limit then lost it in the rain I’d say that was avoidable..
Little dissertation over..
Your opinion and others vary, I respect that, but it’s just an opinion it’s not a fact..

3 star Ncap rating is hardly impressive with or without Michelin tyres on .
Maybe look into a F10/F11 5 series
