Hankook Ventus R-S4 Extreme Performance Summer Tire for Competition & High-Output Sportscars in 255/40ZR17

These tires have been an awesome addition to my car. The soft rubber creates a much smoother ride on my commute to/from work. They are much more compliant than the tires I previously had.

As for track handling, I've put one track day on them but was super impressed with their grip both wet and dry. My last track day was one where we got the first session in the dry, then it started raining for the rest of the day. I was amazed that I could go almost as fast in the wet as in the dry. Only had a small slide once in the wet. Prodigious grip all day long. Zero to no fade once they quickly heated up. Pushed them hard in the corners and brake zones and could put the car where I wanted all day long. I would definitely purchase them again.

Out of the other tires in this catagory iv tested, (Advan AD08R, Federal RSRR, Hankook RS3, Sailun R01, RE71r) these are all around easily the best. They outgrip all at the limit except the RE71r, which i was about 0.2 faster in. These also have the lowest treadwear, lasting much more than twice as long as the RE71r, and very similar to the AD08r. You can do several track sessions in a day without experiencing any over heating so they make for an amazing track/endurance racing tire, unlike the RE71r. They also perform quite well in the wet in comparison to the others as I also daily drive these tyres. They are a bit noisy but manageable. The price also places them at the cheaper end which makes it all the more worth it. In overall dry grip for this catagory they get 2nd place. But for every other catagory (wet, comfort) they top the chart

This is my third set of hankook rs4's. Very good dry traction, sticky when warm, autoX runs get better each time. I have 25 events on my last set.

I've worn these tires out in 5K+ and that's a good thing. I purchased the tires to attack curvy mountain roads and they lived up to my expectations. They were exceptionally sticky and gripped amazing. I never lost grip when they were warmed properly. I will be ordering a replacement set in the next few weeks.

I bought these tires to replace the Hankook RS3 tires that are not made size I needed for my Cayman S (with a 3.8 liter flat 6). I am a Porsche Club instructor and my car has mostly Porsche 911 GT3 RS suspension parts, and Bilstein PSS9 coil-over shocks. -2.5 degrees negative camber front, -1.7 negative camber rear. Pagid Yellow pads with stock drilled rotors. Around 300 rwhp. I drove these tires on the street all 2018 including 1366 street miles and 634 track miles. Of the track miles, 479 were on Road Atlanta where my best lap was a 1:44.30 and 85 laps were at Memphis International Raceway. Both are run clockwise and I touch 140 MPH on both tracks. I push the car and the tires about 9/10 on most laps but during the later part of the sessions I push them 10/10. I'm usually keeping up with spec boxers in the turns and leave them on the straights. The tires don't have as much grip as a full track compound but they have plenty to reach 1.2g in turns consistently and reaching 1.4g in turn 6 at RA. For all 6 track days in 2018, outside air was over 90 degrees and track temperatures were over 110 degrees. I found running with 36 psi hot was the best pressure. In the wet I found these tires entertaining. They will spin in the rain even with traction control on. I have plenty of tire of 6 more track days in 2019.

Fantastic tire for endurance racing. Great grip along with fantastic wear. For 24hr Lemons racing we can get easily 2 days (19 hours) of hard racing on a set and have actually made 2 full races on one set.

As a long-wearing "200" TW tire, this is fantastic for track day use at a significantly lower cost per day than faster tires. It is not as fast as RE71s or R-compound options, but I don't think I would have done 12 days in a 4000lb car on something faster. If you're chasing lap times, there are better options. If you want something predictable, fairly fast, and cheap to run these are great. Noise, ride quality, and road manners are as expected for the category. Watch out for availability: they arrive every spring and sell out before the following April.

I put these on the Miata early this spring and used for a full autocross season (15 cumulative events). This was my first year in the Miata, after switching from my heavier front-drive car, so I was pretty sloppy and abused the tires pretty roughly on the autocross courses. Lots of lockups, spins and post-grip revving. Given that, they have worn surprisingly evenly and never melted or hardened.
When brand new, one thing I noticed was that they didn't talk much at all at the limit. I could feel them breaking away, so it wasn't bad at all not to have to listen to the squealing. They still don't make a lot of noise, after a heavy season (it's a 2-driver car) so I'm hoping I have enough soft compound left for another season. Very pleasant to drive on them to and from the events. No harshness or roaring. I think those (the streetability and wear) are their main advantages over the time leaders (the 71R and Rival S) which are probably a tenth or two faster on identically prepared cars.
