summer tyres

[Stinger33gt]

Hello everyone, a few days ago I became the owner of a 2018 Kia Stinger 3.3 gt awd. Islam to buy 4 new summer tires, wondering between Michelin ps4s and PIRELLI P-ZERO(PZ4). What is your opinion?

Здравейте на всички, преди няколко дни станах собственик на Kia Stinger 2018 3.3 gt awd. Ислам да си купя 4 нови летни гуми, чудя се между Michelin ps4s и PIRELLI P-ZERO(PZ4). Какво е вашето мнение?

Well, Michelin of course, since that is what I have run on my 3.3L AWD since day-one. If there is a stickier street tire out there, I haven't heard.

 

[Stinger33gt]

Thanks for the replies I ordered the Michelin PS4S next week they will arrive and I will write reviews how they behave.

Благодаря за отговорите Поръчах Michelin PS4S другата седмица ще пристигнат и ще пиша отзиви как се държат.

Other than the cost, I think you're going to love them, for as long as they last, which is the other negative, soft tires wear quickly. I've never gotten more than c. 15K miles out of my rear PS4S/PS4. Almost a ratio of two rear sets to one front set.

I came here to say a big NO to those P Zeros.
So, good job on ordering those PS4s, neighbour!

Other than a track, where are people driving where they think they need the PS4s? I have yet to slide out on the stock Michelin Primacy Tour at speeds well above the speed limit in my 23 GT2 AWD.

Not about sliding but about the steering feel and response. You'll feel the difference on any twisty road. The PS4 feels better in comfort mode than an average UHP premium tire in sport mode.

I have two AWD Stingers and currently three sets of tires.

During my first winter with the 2.0L Premium, I put my Nitto Motivo UHP A/S tires on, on the GT staggered wheels. In the spring I put the OEM A/S Bridgestone tires back on, on the OEM 8" wheels squared, and have kept them on well over a year. The Nittos went back on my 3.3L for winter driving, and I have had the Michelin PS4S back on since early spring. I push corners when the way before me is clear, I'd say pretty much every time. The A/S sets do "slide" but it is in the nature of a controlled drift, whereas the PS4S have yet to slide out. I've gotten them to squeal but not slide thus far. Ima chicken to push quite that hard yet.

Of the two A/S sets, the Nittos grip the best - I wouldn't say "close" to the PS4S, but close enough to satisfy for fun street/twisty driving. The main factor in steering feel, for me, is the Eibach sways front and rear, not the tires, but that's probably because I don't push corners hard enough to need that added feedback from the best grip that the PS4S gives.

The PS4S in front are getting worn. The RF tire is most of a year older than the LF and is worn down to the wear bars in the center tread. When I need to replace them, soon, Ima not likely to get new PS4S, and will likely get a second set of Nittos and run them on both cars year-round once the Bridgestones are shot - which could be next year, because they will be six years old by then, even if the tread isn't completely used up.

I am a true believer that a set of high-quality UHP tires is the best price/quality "tuning" you can add to a car. It immediately changes the steering feel, response and driving dynamics.

And then there's safety.
Here is a comparison in dry braking performance between summer UHP and all season UHP. Both tests were done with a Golf Mk7. The all seasons were indeed on R16 and the summers were R18, but I don't think that makes all the difference.

An emergency braking event on the highway (from 85mph) will be enough to convince you that a summer UHP is worth the money. That is, if driving enjoyment is not your thing.

 

[Snicklefritz]

I hadn't even considered the braking distance differences. smh. am rethinking this. my recent near miss probably would have been a hit if I had not been on the PS4S. it was that close.

I could get the back end to cut loose with the Primacy's if accelerating hard entering traffic. Much harder to do with the slightly sportier tires I have now.

Вече прекарах една седмица с тях и мога да кажа, че гумите са уникални. Една идея е по-меко и колата просто е заклещена на пътя. Препоръчвам ги.

I'm not disagreeing that UHPS tires will have better grip in summer conditions, and sometimes wet conditions. I just can't justify a UHPS all year around or swapping a snow tire in the winter if they don't get much snow, but it gets cold enough that UHPS tires start getting hard and losing traction.

I think UHP all seasons are a good compromise.

Now, if I lived in an area that got more than like, 2 days of snow per year, I'd absolutely have a summer and winter set.

This is where I'm conflicted. Some years at most we'll get flurries. Some years we get hammered so hard we're snowed in for almost a week or get a decent measurable snow several times during the winter (and sometimes early spring). But every year we always get below freezing temps. Thankfully I work from home 100% so if it does snow I don't really need to go anywhere.

Currently I have the DSW06+ on (they came with the wheels second hand) and they're perform pretty well. The stock PS4 summer definitely work better in the summer. I do have a set of winter tires I can put on the stock staggered wheels if needed (currently have the summer tires on them, but sitting in my basement).

I'm running Bridgestone Potenza Sport and they are done after 3 seasons @50k km. From what I read here that is a good mileage. Recently I felt some understeer and will be changing them next year, the rears are also worn out. What do you recommend for the summer?

 

[Snicklefritz]

What do you recommend for the summer?

Oddly placed question since the northern hemisphere is almost into winter now.
My comments above are going to look schizoid, because I recently ended up ditching my PS4S and had the Nitto Motivo UHP A/S put on my aftermarket "summer" wheels. They will be carrying me through the winter and into spring and summer next year - God willing, of course. I am no longer going to switch to Michelin summer tires and back again to my winter setup. A/S it is going forward. The Motivo's are pretty cool because they have that "Y" 186 MPH speed rating. They grip well. But I am going to have to remember the stopping distance I am giving up by losing the summer tires. I guess that means paying added attention to idiots who don't look where they are going and barge in front of me. I'll have to slow down earlier when entering roundabouts, for instance. Don't trust anyone.
