Tyres From 215 to 225 tires

As said if you really want to optimize it, you'd change rims as well. But there shouldn't be a lot of difference between 215 and 225. Except 225 tends to be a lot cheaper and your choices aren't as limited.
Rims are allready here TEC Race 8,4kg, today I ordered PZ5's maybe a failure, we will see.

And yes I read your review but I did some research, the rubber blend was changed on the SC7 (from D to C on rolling resistance) and read other reviews. So I decided to go for the PZ5 instead of the SC7.
 
I run 32psi
Thanks Spilner I'm starting to think that going with what's suggested on the door shut
Should be fine. That's if you don't start changing thing's. I'm not that brave.or wealthy to be fair.
Thanks for your imput I appreciate it so like you I'll stick with 32psi also.
 
The 225 PZ5's arrived today, the rubber blend is softer compared to the 215 PZ4 HN.

The shoulders are softer so the carcass in the HN is specialized, altough the carcass of the PZ5 should be more rigid through its higher load index 92XL instead of 89XL. This tells the HN is super ordinary reinforced.

Another Proof is the weights I measured!

PZ4 HN 215/40 R18 = 9,4kg
PZ5 225/40 R18 = 9,4kg

The PZ5 is Just a Bit wider not 1cm at all, Overall diameter about 7mm.

So could maybe only Michelin's Super Sport as 225/40 R18 HN the answer.

Hello!

I agree with p_b82, concerning the different height of the side wall. It has to be softer and maybe, in addition, the side-wall-construction of the P Z 5 is softer generally. So you have to drive with 2.6 bar to compensate this difference and to achieve a similar handling, compared to the P Zero HN.

I agree too, that the tires (and setup) has to suit your driving style.

By the end of this week, i will change from the P Zeros HN to Hankook Ventus Evo (K137) in the same dimension. Let's see, how it works for me.

Bye, Gerhard

How are the Hankooks going?

or maybe continental sport contact 7 225/40/18?
 
I don't think so as the Conti SC7 also isn't extra reinforced, as the HN labeled ones.

I worte it already in the german section I think. I will made a tire review when the N was on dealers recall and a couple of 100 kilometres are done with the PZ5.

Yes we bought the PZ5 and they are mounted, before that I saw an explaination on both tires sidewall, 215 PZ4 HN & 225 PZ5.

The HN got 1 layer on the carcass and the running surface more than the PZ5, I think similar to every other UHP & UUHP tire which don't got HN labeling.

The PZ5 is a bit more comfy, in corners it is softer vs zero mm on the old PZ4 HN.

But it is getting better and better not even 1000km done. Had a little blast already, driving has to be suited to new few mm thread, of course there is more delay and the tire is right now less sharp! Steering has to be more predicted before you enter apex.

If you enter apex with full throttle the build up of crip is even now immense. In my opinion the softer carcass will allow more surface contact with the tarmac.

On the rears the less rigid carcass will suit fine the less weight on the rear axle. So less tendance for lift-off oversteer, which I prefer.

I have the feeling that the PZ5 after 3000-5000km will totally outperform the PZ4 HN handling characteristics.

On Furka Pass we had a lot controlled understeer on both front wheels while LSD was fully working, there was the PZ4 HN limits reached.




What me also decided to get the PZ5's

A friend of mine mounted the Hankooks Evo (K137) onto the rims and when driving home, i drove some big circuits to test the new tires. When mounting, we agreed, that the sidewall is less stiff compared to the P4 HN. So we increased the tire pressure. But that was no good idea. After i drove about 40 km of twisty roads, the tires became sticky. But the behavior of the car wasn't really satisfying. So i reduced the pressure in little steps and i felt, that 2.2 bar is optimal for the Hankooks too.

On my way back home i enjoyed about 220 km of twisty roads over some little mountain passes. The Hankook does not have the initial turn in bite of the P4, but during the curves, i feel they are more accurate. Although they are more comfortable over short bumps. Maybe, because of the amount and softness of the fresh rubber on a new tire. The rear is more agile compared to the P4 HN. In some turns i had the optimal turn in speed and the rear was really light until the car came into a four wheel drift, which was smooth an very easy to handle (by accellerating and minor steering correction). The P4 HN feels in this situation more nervous, like a race horse in the starting box.

At home i watched the video, i make on every drive. The G-forces of 1.04 were the same, as with the P4 HN, although the weather was cooler than the last few drives with the pirelli, which produced more grip, the less rubber was on it. On the front remained 1.6 mm, in the rear a litte bit more.

The Hankook suits better to my driving style, than the Pirelli. They have less wear, but not so less, like expected. The last difference i noticed, is the Hankook has less rolling resistance.

Gerhard!

What me also decided to get the PZ5's


Also looking to replace my HN's with PZ5's as the wet grip seems to be quite impressive based on reviews and outperforms some competitors in the UHP tyre range.

How have they been holding up since your post? Do you still recommend them? Found a good deal on them in the UK and as it rains a lot over here, a tyre that performs well in the wet seems like an easy choice!
 
Still happy with the PZ5, all I can say is they are still getting better. They are a bit laggy, or let's say progressive, yes they work/move more on the rim. Therefore they can build up more grip. And yes the car is about 2-3 seconds slower on 100-200.

The compound is softer so more resistance, also more width and diameter.

If you want to keep that initial harsh directness on the steering wheel, don't buy these or any other contender.
Stay with the PZ4 HN or by the frist to try 225/40 R18 Michelin Super Sport HN.

Otherwise step up to semi slicks!

But in my experience

Everything else is better with the PZ5, grip from cold & in the heat, and on the brakes.
It is more comfortable and forgiving, plus it is a lot better in rainy conditions. Of course the ride is more gentle, this extreme harshness with the PZ4 HN ist gone.

At the end of the day the PZ5 is quicker on a extreme b-road blast, although it is not as direct and sporty in feel.

Did you change the width to 225 without TĂśV Abnahme?
I fear that the origin pz4 HN will not be produced for a long time after canceling the i20N on europe.

My last idea was going to Conti sc7 before reading the news about the rolling resistance...

And I never heard about these Michelin with HN spec.
