The V730's are a very under rated tire. I have really good luck on them!

Cool comparison, Rob 👍👍

Love this comparison, thanks for the video. I think this shows just how much value the V730s pack for the money. They've exceeded my expectations and seem pretty on par with the RT660s ive used in the past. I need to get a set of RE71RS's in the near future!

It's good to test and draw your own conclusions, but if you like the V730; I'd skip the RE71RS and try the CRS. The Nankang should have much better heat tolerance like the V730 and RT660 for that matter. If the price is a concern, try the Nexen Nfera Sport R. That's the tire I plan to test next. Supposed to be very similar to V730, just just a little fast and comes up to temp quicker, but can still handle the heat. Of course it's all subjective and opinionated. You might love the RE71RS.

Interesting runs, but woah i'm just learning about using a telemetry with go pros.. are most of these overlays subscription or paid based? I really want to explore this for once i start tracking my car!

All of the data comes from a race technology data logger and is overlayed on the video. Race Technology does have a GoPro app that will use the gopro's internal GPS and acceleration sensor. You could try that. www.race-technology.com/us/gopro

Great comparison. Whats your camber?

This is cool, but just a suggestion if compiling the data is configurable enough: it would be cool to see the Faster Slower placed between at top where times are, then it just glides to whichever side is faster atm, so essentially Faster/Faster if that makes sense but with the line drawing eyes to either side naturally. Would this be the greatest way to analyses serious info? absolutely not, but it would be super mentally satisfying from a viewing perspective, the graph at the end is still there for any serious quandaries.

Great idea.. I could make that happen for future comparisons. The Faster/Slower bar graph is a comparison of the current lap to the theoretical best lap in real time. It is only in reference to the video it is on, and is not comparing the two separate videos. I stopped using that graphic, but if you go back through some of my other videos, you'll see it shows where I was faster or slower in comparison to the best theoretical lap I could do and I think it'll make sense. These two videos were a year apart but I can totally see how that might confuse people. Lastly, since you took the time to comment.. The RE71RS is the faster tire. No question about that. The point of the video was to show that it should have been a much easier tire to drive at the limit and should have produced much larger time differential than the V730 easily. However that was not the case. I find that V730 is so consistent in the way that it reacts, the driver can make improvements that become significant. The super 200s let you get away with murder so to speak. They cover all sorts of bad driving errors and don't really allow you to get the seat time to learn how to pick up tenths. I much prefer a more consistent tire.

@@roboks2k Thanks you for the detailed breakdown, the V730 sounds like a absolute winner for what its worth. Can't argue with you on tires at all for me the best thing is having a vehicle that listens so the delayed response when corrections are needed with the 200s sounds rough

Very interesting! So same times? I really think consistent tires that have nice slip should be valued more even if they aren’t thought to have as much peak grip

@@ilanbandary4435 The S2000 steering is not very good. It's one of the cars only faults. Both tires feel direct, however the V730 maintains its level of grip for the entire session. This means that its feel is consistent every corner. Whereas the 71rs is so unpredictable after the first 2 laps that you won't know when or which axle will lose grip.

This is so strange because the V730s are about 1.5-2 seconds slower on my NC Miata vs the RE71RS

V730 likes low pressures, and far less camber due to the stiff sidewalls. 71rs is faster but that window is closer to 1 second on the 1st lap. After that it's not more than a half. When considering pace, driveability, longevity, heat tolerance, and cost... the V730 is my personal favorite tire available.

I have an NC miata and I'm starting out around 24-28 off the trailer (big split to get the rear to rotate) Car feels good the first session, and I pick up 7psi typically.

@@JNatella I run 27-28 hot. That's like 21psi cold. I'm a believer in the 1psi to 100lbs rule. So if your car is 2600lbs in race trim, you'd test all the way down to 26psi hot. Each tire will be different but you should actually be close to those numbers. It's hard to say for your specific case, you'd have to check with a pyrometer. Start first with the tires, get them into the right window. Wear and drivability will help you make other changes to improve the cars handling. Always start with the axle that has the issue. If understeer is the problem... Try to solve it at the front axle with spring/roll/alignment, before taking away rear grip. The V730 wants to be driven very precisely. So if you are seeing a lot of slip, you're throwing the lap away.

Interestingly, re71rs is 100$ more. Will v730 outlast threadwear re71rs as well?

Yes. 71rs is faster but only lasts about 4 days; 3 of which are fast. The V730 will last about 8 days; 6 of which are fast. If lap time is your goal 71rs is faster but in my opinion it's not a "better" tire.

@@BuntaTesla V730 is light-years ahead of the RS4. V730 is faster, wears longer, and has a much higher heat tolerance. Nexen sport r is slightly faster than v730 but has soft sidewalls and only lasts about 5 days. Both are priced the same. Heavier cars seem like the Nexen sport r more and lighter cars prefer the v730. The Khumo likes low hot pressures too, and much less camber than most because of the stiff sidewalls... They might be the stiffest of any track tire ever made.

The 71rs gets shredded on the first day just like the old 71r did. They do last longer though.. they even get a little faster and easier to drive on the 2nd/3rd day. As they wear into the 4th day they get more difficult to drive and lose a lot of pace.

@@roboks2k Thanks again. I was also looking at the Nexen. I have a stock power 2023 BRZ with extensive suspension mods and lots of camber (EDIT: no aero... yet). Does that count as lighter or heavier? It's kind of in between, lol. Probably about 3100lb with driver. I've so far run very used RT-660s, old Supercar 3R, and now RE-71RS. My fastest lap is on SC3R, but only by 0.1s compared to the new REs. I improved setup a lot since the last day on the Falkens, so it's hard to compare. I'm putting together a tire trailer, so I'm actually looking at "Endurance 100” grooved slick options, too.

@@grippgoat For the price they are both worth a try. The Nexen needs higher pressures cause the sidewalls are really soft.... Too soft for my liking. The V730 likes lower pressures. Like way lower than you'd think cause the sidewalls are very stiff. The Maxxis RC1 is also a great tire. It drives very similarly to the V730 and has great heat tolerance as well. These tires will not be as fast as the 71rs or the other super 200s, but they have endurance and consistency. They are so consistent that you will learn more driving on them that you will probably go faster than your times on the 71rs. They literally teach you how to drive by allowing you to make the most of every lap of the session. Every tenth gained is something you learned! The super 200s are so inconsistent after the first lap that you can't really tell what is going on.... You'll set a handful of fast laps but most of it was just the tire covering up bad driving 😂

On the left video the car was unstable under braking and I dropped the right rear tire off the track which caused an oversteer and correction just before the corner. I found the 71rs to be the most inconsistent tire I have ever driven. The first lap or two is great, but after that they are dog shit to say the least.

@@jongwoo I absolutely hated them! With that being said they were really fast. It's a 1 lap hero tire. It is not better than the A052 which is still the fastest and the most drivable tire of all time. It does everything exactly perfectly for 1 lap as well. After that both tires fall off. The 71rs becomes the most inconsistent tire I've ever driven and the A052 becomes one of the best. 71rs breakaway becomes sudden and it's impossible to tell which axle it will affect. The A052 just lets you run the biggest slip angles with ease. It feels as if it's communicating telepathically with you. It is exceptional. 71rs is like a game of chance.
