Why Does Hyundai, Kia, & Genesis Use Michelin Pilot Sport 4s Tires?

Anyone have any thoughts on this? Have people found lesser all seasons to seriously hinder G70 handling? Does the handling performance rely too much on performance summer tires?

Why Does Hyundai, Kia, & Genesis Use Michelin Pilot Sport 4s Tires? – The Answer Will Shock You

Hyundai, Kia, & Genesis use the excellent Michelin Pilot Sport 4s tires on many of its performance cars. You may not like or even agree to the answer why, but it’s not just because the Pilot 4s is a great tire.

It's really about the market. Other sports sedans have dedicated summer tires, and when magazines like Car and Driver test a car, the tires are going to have a significant impact on road holding and braking distance.

Agree that sports cars are generally going to come with summer tires. I think the more targeted question is whether G70 handles better in reviews because it comes with (arguably) the best summer tires, and competitors come with lesser rubber. Put another way, if you put an S4/M340i on PS 4s, does the G70 still outhandle them?

I saw this article this morning. His statements are not based on any real facts and he's clearly lacking experience. Because the G70 doesn't have a double wish bone like the G80, it's not a great hanging car? Pretty sure it easily outhandles the G80. His other data is based on information he got from someone he wrote to online that swapped tires with an accord and said the accord handled better?? You can't write articles or even opinion pieces based on other people's subjective experiences and expect to be credible.

I have a 3.3T with all seasons and it's a great fun. Not in ultimate grip because they are all seasons and naturally lack grip but that is different then handling.. something that seems lost to him.The accord is a front wheel drive car. It's lighter, so the subjective feeling may be that it is more nimble and sticks better. I doubt it.. the car isn't tuned for that.

It’s not even a really aggressive summer compound. If Genesis was really trying to hide handling faults by over tiring they would have put the PS4S/cup2 on all 3.3 trims

Not sure what Audi puts on the S4 but I believe that a BMW M340i can be optioned with non-run flat 19" PS4 (which is typically the setup provided for the press for their tests). Alfa Romeo Giulia comes with Pirelli P Zeros if you select the summer performance tires. The G70 is not doing anything different than the other credible drivers' cars in the segment. Cars like the G70 are designed around specific tires to optimize their handling and overall road manners. That was one of the big points when they launched the Stinger and the G70: the fact that the car came with these tires and Brembo brakes was a first signed that they were designed with enthusiasts in mind and they did not cut corners where it matters. I don't think the narrative of the article makes sense: if you put an inferior tire on a G70 and the better tire on an Accord, the Accord does not become all the sudden RWD with a near 50/50 weight distribution. I use winter tires on my RWD G70 and the car retains all its manners and handling characteristics with the Pirelli Sotozero... I would just not hammer it on a track with my winter setup. You can feel it is inferior to my summer set but not my a lot, under "normal" driving conditions (that can include back roads taken at a decent pace)...

Haha, it's this kid again. Take his opinions with a huge grain of salt:

I saw the article with his face on it, and read up to the point where he falsely claimed that the Kia K900 had a strut suspension. I stopped reading at that moment. Going from your description, it sounds like I made the right choice.

The claim about the Accord is total rubbish. The G70 has a staggered tire setup while the Accord is squared. They're not even the same size (235/40's on the Accord vs the 225/40 and 255/35 on the G70). Dude has no awareness of basic facts.

Yeah I guess the squared G70s don't come with PS 4s... good point

To add to that, the squared versions of the G70s are 18 inch wheels- the Accord is only offered with 17 and 19 inch wheels. So there is not a single tire the two have in common.

I think it's stupid when a manufacturer makes a sporty car in RWD and AWD (like Genesis) and whichever version you get ONLY comes with summer tires. If I'm going to have to swap tires anyway, I would much rather just have the lighter, more fun RWD version. This was the case in 2019, but I think they rectified it in subsequent years and now you can get all-seasons on sports.

I will say that I had a 3.3 sport loaner with the PS4 tires and they were sticky icky and handled great.

Especially after driving that car, it really shows how woefully insufficient the 225-width all-season 18-inch tires on my 2019 3.3 prestige are. I know in 2020 they finally put the staggered setup on non-sport 3.3's, and I feel like I kinda got the shaft on that one. It really has more power than those tires can handle.

I do not own a G70, however it seems that summer tires give this car a .04 g advantage over allseason tires per Car and Driver. The G70 still handles great on all season tires per their test. .91g vs .95g; both are great numbers for a mid-sized sedan. Therefore, the G70 great handling is not solely based on summer tire compound.

The 2018+ Accords are great handling FWD cars, but not as nimble as the G70 even with both using all-season tires. The Accord is tested at .88g on all-season tires. The G70 test at .91g on all-seasons.

I have an 2015 Genesis 5.0 Ultimate with the older overly stiff active sport suspension equipped with performance summer tires and my 5.0 can barely handle as good as the base G70 on all-season tires. My car is rated at .86g on Hankook season tires per Car and Driver; so I assume that my Falken Azenis FK510 summers tires brings my 5.0 handling up to about .90/.91g. However, this information is not track tested, but I agree that the softened tuned 2017+G80 Sport will not handle as good as a non-sport G70 even with the same summer tires.

When you can’t think of any real negatives you resort to making things up about the tires. A for effort

skroonigan · Aug 18, 2020

Yeah, article is dumb.. Small part of why I bought the G70 was to try out the PS4S tires. Even if it hides deficiencies who cares? It just tells Hyundai/Kia/Genesis are serious about performance if they spec these tires, which is why you'll likely never see these tires specced on an accord.

petraman · Aug 18, 2020

My G70 has all-season Michelins and I think it handles and steers amazingly well; worlds better than the B8.5 A4 which it replaced (that, funny enough, I put PS4S tires on. I spent so much money trying to make that car handle better and nothing I did really improved things; contrary to all the beaming reviews on the parts I installed.) As said before, BMW puts PS4Ss on the 3-series and most of its other cars, do you think they're trying to hide handling deficiencies?

This is nothing but fishing for clicks.
