Flat run tyres or not. Pirelli Cinturato P7 91Y 225/45/R17

[Tessie Two Shoes]

Please help. Front tyre found flat with screw puncture. The above is the tyre size & I ordering online for a mobile fitting - the search for my exact registration brought up this same tyre so I ordered that. I haven't been able to work out if the tyre is, in fact run flat or not??

When it came to confirmation they said that's a "run flat" tyre not meant for this car - which clearly is not the case according their own & other websites. This same tyre keeps coming up. The tyre they've ordered is the non- runflat version apparently. Is this just bs & they want to shift other stock?

It's £12 cheaper but aren't the run flat tyres safer & better for someone who can't change their own tyre?

Please advise - should I just insist on like for like?

The rims for runflat are a different shape, you cannot safely fit a runflat to a non-runflat rime. You can fit a non-runflat tyre to a runflat rim safely.

I think the terminology is J for non-runflat and JJ for runflat. If your rim has the size and type visible it will have a J or JJ, this will tell you which sort it is.

So, was your tyre runflat or not?

Personally, I wouldn't have runflat on any car, so am biased but it certainly won't be because they "want to shift old stock" as both are made still & will be for a very long long time yet.

Have you checked the tyre sticker on the B-pillar of the car or in the manual?

Let's be honest basically nobody can change their own tyres, so not really sure why you added that.

You can fit either on either rim but if you fit a RF tyre on a non-RF wheel it will not be RF as the tyre & rim must both be RF for it to work.

Couldn't see anything saying RF or similar so I think it must be ordinary. I guess Ill go with what the man says. Thank you

Hi. Thanks, I think it's an ordinary type so I'll go with what the man advises. Thanks

When it was "punctured" did it look flat or not?

Agree. This is important.

This shows the tyre markings on different brands that identify thay are run falt.
