Hi all,
I have a 2016 Alhambra with TPMS. I understand that the sort of TPMS fitted works by uses the ABS wheel speed sensors to measure the rolling radius of the wheel to detect punctures (so-called indirect TPMS), rather than measuring the actual pressure at the valve (direct TPMS).
I needed new front tyres, and given the absence of a spare or even space-saver wheel, I ordered Bridgestone DriveGuard runflats. The reputation of the pathetic puncture repair kits is notorious, and in particular don't help with sidewall damage.
But the tyre co I usually used in the past are saying they don't think they're right for the Alhambra because it doesn't have direct TPMS and they claim it is unsafe if not. I get that direct TPMS is more accurate, but from all I've read, the only requirement is that it has some form of TPMS. The tyre guy thinks that run flats hold the shape of the tyre so perfectly that the rotation speed won't change. From what I've read with people testing run flats, I'm not convinced.
The Alhambra manual even says: "If replacing tyres, make sure the new ones have an emergency ride system (Conti-Seal / Run flat)".
So is the tyre guy misguided? Can you use run flats on an Alhambra? This company is normally good, and as they said to me themselves, they could have just gone ahead and taken my money and fitted them. That's noble, but that doesn't make them right
BTW, I also rang Seat, and they said it's fine, but I'm wondering if I'm going to have to get them to put it in writing for him to believe me (his words were "Although you have contacted Seat with regards to the fitment of the tyre I do not understand how they can say that this is safe. You do not have runflat sensors on the vehicle and as such you will not know that the tyres are punctured and you will then run the risk of further damage to the wheel and vehicle. Furthermore I am still not convinced that the rim would be strong enough for the tyre either.", and when pointing out the car did have TPMS, he said indirect isn't good enough).
Anyway, any info appreciated, thanks!
