There are so many factors when it comes to tyres. Coming from Southern England and now living in Scotland my awareness and knowledge of tyres has increased dramatically, why you ask, because the conditions / temperatures in Scotland can vary dramatically in the space of a single journey and we are talking under 50 miles. If anyone thinks any HP summer tyre is going to perform the same at 5 Deg compared to 20, or a tyre is going to perform the same at 7mm vs 2mm, then my recommendation is to go and look up tyrereviewer grab a large coffee and educate yourself! And a majority of the driving population need to do this, differences in braking distances in various conditions and temperature in particular!
There are so many elements in how tyres perform, for majority of road users in the UK a good AS tyre is all they need and all cars should be supplied with them from new IMO, and case in point with GR’s being fitted with them and performing well, I know as I was following one fitted on a GR meet.
If the tyre industry made a HPAS tyre that would be nirvana for Scotland and England for those that didn’t wish to track their cars.
This evening I went less than 50 miles from Scottish Boarders to Burntisland, temp fluctuated between 4-6C and roads went from dry to damp. Car is on the PS4’s (2.3k miles and no track time) and car felt good and progress was the same, but I was driving to the conditions, coming off roundabouts I was not putting the pedal down like I would when it is 15C or even 10C. In Fife, on the outskirts of Inverkeithing there is a roundabout that has negative camber and I know it can be interesting at this time of year, sure enough the back came away and traction light came on, car was not in low gear nor high in the revs. Did I think that I need to change the tyres tomorrow, no.
I do agree that you can have the same tyre on two different cars and they behave and sound different, as my other car has PS4’s on (and I prefer them on it compared to the GR), again lots of variables at play. Therefore don’t think that a car you had previous on say a particular conti set that made the car handle to your liking would make the GR feel the same.
Will I get PS4’s again, no as things have moved on and less tyre noise is what I am looking for from the next set. Yes you can go onto tyrereviewer and see what the top 3 tyres are this season and yes if you had the same car as the golf GTI they used chances are the number 1 tyre may be spot on, however may not perform the same on the GR. This is why seeing what people on this great forum are changing to and they thoughts should be put into the mix in equal measure. It’s a gamble as sadly you can try tyres before you buy on your GR.
Just my 10p worth and I am sure Sonic can agree on the roundabout in Fife
