looking to buy new tires. What to get??

I need some new shoes put on car,
I drive daily on highway and when in town i like cornering fast tight turns. I do not track the car.

235/40/18 is what im looking for, due to rims i cant go wider. i normally run 225/45/18

anyone have any suggestions on a good tire? i have read alot of reviews and they all have good/bad comments, i want a quiet ride lol

hankook ventus rs3 / v12 i am tossed between these 2 tires, any other options?

I'm all over this forum praising the V12's, and I track my car.

I pumped up the psi to 46 fronts hot for the track, and then drove home with the same psi without drama, roughness or noise.

I'm running Hankook Ventus V12's in 225/40r18's, and will definitely buy the same again next time.

I considered the rs3's, but I think they might be too sticky for a street tire by maybe picking up gravel, etc.

So after I think I've found my tire, TireRack.com finally tested the Ventus V12 against the Dunlop Sport MAXX TT and the Sumitomo HTR Z III, both of which showed to be better.

The Dunlop beats all tested in dry and especially wet traction which you'll need in Florida, and it seems to be the firmer steering feel (bumps, too).

The Sumitomo was actually the fastest lap tire.

I still think I like the V12's because of the softness and I think still less noisy, and I don't think most testers are adding enough psi.

Running the V12's after running my Kumho SPT's leads me to believe that many tires need different psi even on the same car which I don't think tester's do because it's very time consuming.

For the price and performance I would definatly consider the v12s. I bought my car with the kumho spt tires on and they were a very good tire for the price, so i recomend those to people on a budget. Personally I wanted the most traction possible so I currently use the yokohama advan neova ado8.

well i have had sumitumo on one of my last cars, and they had ALOT of wheel noise. and they always became chopped as thread went down.

i think i am going to go with the v12's as well.

See? That's what I'm talking about!

That op thought he was really pumping them up, but the V12's only started working for me at 40 rear cold (80 deg) and 42 front cold (80 deg).

He's running 4 psi less in the front and 7 less in the rears.

Go see the competition tire pressure chart on TireRack.

They recommend front cold psi from 35-45, and 30-40 rear cold.

The tires can take 50 cold, but 50 hot is where I'd stop testing.

yea, it depends on what you want. im not trying to discourage people against the v12.. just pointing out that the sidewall is much softer than oem tires. as others have said.. you can increase tire pressure to somewhat counter it, but not really. fyi, i run daily at 38psi cold. still soft, but ok.. i don't see any abnormal wear so far, i guess about 2000 to 3000 miles.

hey, how many miles have you run at that pressure and do you see any abnormal tire wear? if not, ill pump them up tomorrow and have a go at it. thanks for your inputs.

I've got 7k miles on the V12's, close to a year, 3 track days, and one canyon run on a 98 deg day.

The most wear is on the inside front's where it should be with 6/32's (tire starts with 9/32's).

I'm gonna rotate before next track day in Sept., but NO ABNORMAL WEAR, and they wear way better than the SPT's that I got 20k out of with rears wearing twice as fast.

In other words the centers are not wearing too fast with the high inflation like you'd think.

Also, I realigned and picked the rears up from the -2.1 camber to -1.65, and it keeps the rear planted on acceleration.

Have Yokohama S-Drive's for a while now, and they have no problems so far. I've always wanted the look, the handling, and the performance from a tire, and i got all 3 with the Yokohama S-Drive.

Continental DW is an excellent all-around tire, with very good dry performance and excellent wet performance. They are cheap and wear well. The only downside is that they have a softer sidewall.

Goodyear Eagle F1 Assymettrics are also an excellent choice, which I run now, with a nice, stiff sidewall, good rain performance, and low noise, but they cost more than the Contis and probably won't last as long.

My next street tire will likely be the Conti DWs.

I just looked up Tireracks tests on two tires I understand: Hankook Ventus V12 and Kumho SPT's.

They were tested with the same car: 2011 Bmw, but they say the V12's will pull .90g's and Spt's .95 g's in the dry cornering.

Maybe the track surface was way different on those separate tests, but I found the V12's to immediately out grip the Spt's when cold and inflated the same, and after hot and inflated more the SPT still gives less grip.

I'd give the V12's .95 and the Spt's .90, so I'm thinking those tests are not accurate.

So we're back to tracking our cars and/or comparing reviews and word of mouth.

^So, you did back-to-back tests, both tires brand-new (but with release compound worn off), on the same course, same day, same conditions, using the same car?

I ran with traction control off, V12's on the front with approx 500miles (new), and Spt's on the rear with approx 4/32 ( and 3 years old).

It was hanging the rear out real nice, but I didn't feel that the Spt's had degraded much from age, and they had about 37 psi hot ( like they should on rear) while the V12's had 40 psi hot.

I ran this last Feb. on a 60 deg drizzly day that didn't wash the surface ( just made summer ice ) with 44 psi hot front, and I was sliding like everyone else, but never slid off ( traction control).

I upped the V12's ( all 4 now) to 46 hot front - 43 hot rear, and they started working.

For the first time NO FAST CARS like Bmw's could get behind me for the 20 minute run, and I was one of the few that didn't plow mud.

My mind says V12's beat Spt's easily, and are softer, and quieter.

The Car and Driver test showed the V12's weakness to be dry braking, and I think the V12's and Spt's are about equal there, with maybe the Spt's slightly better .

Your test is invalid - surely you know that you can't compare 3 year old tires to fresh tires?

In fact, your testing vs. TireRack's tells me that your SPTs DID fall off, even if you didn't perceive it over the three-year window.

Most tires fall off slowly so you can't trust your butt dyno to asses changes in tires over time, particularly on the street. You need consistent courses and timing gear. Which is what TireRack has in their testing.

Yeah, sure, maybe, but answer me this.

Why did the Car and Driver test show Dunlop Star Specs to beat the Hankook V12 a little ( V12 was better on wet braking), but the TireRack test had the Dunlop Sp Sport TT flat trownce the V12?

So the Dunlop Sp Sport TT is better than the Start Specs?

Since you value valid tests, here's some raw data for ya.

C&D Wet Braking 50-0 mph : Star Specs 85.6 ft V12's 85.1 ft*

TireRAck wet brake 50-0mph: Star Specs 84.6ft* V12's 97.7ft REALLY?

C&D Dry G's: Star Specs .92 V12's .93*

TireRack Dry G's: Star Specs .97* V12's .90

C&D Wet G's: Star Specs .86 V12's .87*

TireRack Wet G's: Star Specs .84* V12's .77 I mean come on!



These data points are so far off that my test was about as valid.

Also, I still say that some of the softer tires need lots more psi which their tests don't talk about.


*Winner

It is true, that every test is different. Every surface is different, and subtle changes in car setup (if the C&D and TR tests were even done with the same make&model) will make differences as well. Then there is the small matter of driver differences (this is much more important than most people realize).

So, yes, there are differences between tests, even when both tests are reasonably well run.

For example, surface temperature can play a significant role, especially in a wet test. A tire that needs more heat (such as a Hankook RS3) will suffer more than a tire that does not (such as a Continental DW) in cool wet conditions, but as the temperature rises, so does the performance delta, with the RS3 having a plain advantage once it reaches it's target operating range. But in cool wet conditions the DW will be as fast or faster.

This could easily explain why TR & CD wet tests differ with respect to the two tires you like to compare - it's possible the ambient temperatures were different enough to skew each test in a particular direction.

However, your test of comparing a 3 year-old tire to a new tire is NOT a valid test, at least if you hope to draw conclusions about how two tires compare when new out of the box. If TR, C&D, or any other body were to allow such a discrepancy they would be instantly discredited.

I applaud you for trying to bring some RX-8 specific tests to bear, and the track is a good place to do so - at least for track users. But, if you want credibility, you need to perform tests that are fair and reasonably well thought out.

I completely agree with this. Different tires require different setups if you want to fully optimize the performance, and, as you say, most tests do not address this.

But, I do think setting all tires at at 32 psi and running the test is a pretty good indicator of what your average driver will experience - most do not have the knowledge/opportunity to fine-tune the setup, nor would they run excessively high pressures on the street.

either way, i value your test, and what looks to be a good DD tire and for price is the v12's, or any listed above.

I am not looking for the BEST tire, just looking for something that has put on the rx8 and has been liked and would buy again. or ones that or disliked and would trash them if they could.
