**Unofficial Tyre Thread**

Hi all,

So my Mum has tasked me with getting new tyres sorted for her SUV. 235/55R18.

I want to get something decent (she can afford it) and was looking primarily at the Michelin Primacy 4 as it's well-reviewed but I see there's a Primacy 5 out now. Worth just going for the 5?

The tyres are splitting, and as I said previously, when those splits are opened up the cords are visible, which I failed on the MOT.

Have to check mine carefully tomorrow. Haven't noticed anything but two of them are coming up to 3 years old with 20k miles on them.

Might be time to bite the bullet and just chuck four new SC7s on.
 
FWIW I don't profess to be up to date on tyre technology, but over the last 5 years or so I'm failing (MOT) more and more tyres due to splitting/cracking than any other time in the last 20+ years.
No idea if it's the extra weight, aggressive camber, profile or whatnot, but it's writing off tyres that should in an ideal world last quite a bit longer.
Avon's especially, awful things, don't buy them.

I'm seeing that a lot with some models of Bridgestone tyres - I was putting it down to the lateral forces of SUVs but then encountered several instances on things like Minis and small Fiats, etc.

Obviously the state of the roads isn't helping.
 
Well I just checked my Supersports and they're all fine, no signs of cracking thankfully.
However, I also checked the tread depths which has left me with a bit of a dilemma.

For complicated reasons including rotation and puncture replacements by the previous owner, the fronts are almost new. One has 6mm centre and and 5mm edge whilst the other is around 6.5mm & 5.5mm.
The rears however are getting there. Both are around 3.5mm centre and 2.5mm edge.

The obvious thing to do would be to put a new pair of Supersports on the rear. Thing is I was planning on replacing all of them with SC7s when the time came.

My options would appear to be:

1. Replace the rears with new Supersports
2. Replace all four with SC7s
3. Do nothing for now

Out of interest, if I replaced all of them, I guess I could keep the fronts and sell them on used? How practical is that?
 
I'd just replace the rears with the SC7s and leave the SuperSports on the front to wear out before replacing them too. I know social media will tell you that having mismatched tyres on the front and back will immediately put you in a hedge and set fire to your dog, but in reality you'll be absolutely fine.

*Edit* - caveat here being unless you're planning on selling the car soon. In that case I'd get them all replaced

Guess that's another option, although tbh I don't like mismatched tyres, even front-to-back so I'd be more likely to replace all of them and try to flog the front Supersports.
 
One of my clients has bought their son a Mk5 Polo as he's learning to drive. I noticed it's got ditchfinders on the rear. Plenty of tread but you know that he'll spin it if he goes round a wet corner too fast.
Would you say anything, or just mind your own business?

The car came with SC6 and they lasted roughly 8k miles of hard driving. The SC7s are a much better tyre IMO

I had hoped mine would last well, checked yesterday and the front left has around 2mm left, it's only done 4.2k since I got it. The roads around here are in rather poor condition! looks like some SC7 will be required in the next week or so and maybe having the tracking checked as the front right had more.

Need a full set of new tyres for the F-type. P-zero's on it at the moment but the handling feels really twitchy and had a bit of a moment this morning in cold and damp conditions.

Looking at reviews there doesn't seem to be a huge difference between decent tyres and getting a reasonable deal on Continental SportContact 7's. Anyone got any other recommendations before I throw out a heap of cash?

this review seems to look at them pretty well but I don't have the experience to know any better

I ended up going for a set of potenza sport evo. Car is transformed from the P-zeros. Much more stable and planted, actually able to enjoy it again.

I detest PZ4s

Only time I’ve ever spun a car was with PZ4s on it.


I took a gamble on the new PZ5s and I must say, they’re phenomenal. Like, really good.



They feel like a blend of Asy 6 and PS4S - and the best of both.



If they last, they’ll be my go to tyre. I can’t get them to break traction in my RWD 435i at all.
