You're correct. The name I remembered was Adven Neova, never noticed the AD07 designation. I looked up the specs and see they don't come in 255 (the reason I suppose you didn't list that option). The next best size I see is 285/30, but as we discussed there may be an aesthetic downside to that one (fender gap). Otherwise, I'd rule that option out and try to find something that comes in 255.

 

Hey Kyle,

good point. I'm not looking for traction from a launch, moreso looking for traction around turns and at wide open throttle in the lower gears. The BFG KDs pretty much fit the bill (esp when brand new) but I'm looking to try something different. Besides the prices on the KDs are not exactly cheap, I figure I might as well run something with newer technology.

 

Even that is still almost "launching" to an extent (i.e. trying to have traction for full throttle in low gears). When I'm on a road course, even with r-compounds I have to "roll on" the throttle. I just can't stab it coming out of the corners. IMO, I would get a decent all around tire for the street, and then tailor your driving accordingly.

 

Yeah, I never really considered DRs because I don't launch on the street, and also I always run matched tires.

If the 295/30s will fit in the rear with no problems, I'll probably go with the PS2s. Top of the line tires (at a top of the line price), in proper sizes that'll minimize chances of damaging a fender, with a close to stock rolling diameter of 25 inches. Anything larger affects the gearing and slows the car down.

Merry Christmas, btw

 

Been spending some time on the tirerack, and I have some interesting comparisons. It's no surprise that each tire company has different sized tires, ie all 285/30/18 tires are not created equal

Seems like the Goodyears are the lightest, but not lots of tread width. The Potenzas are heavy, but offer lots of treadwidth for their rated sizes. Despite the price, the AD07s are looking pretty good, I thought a 235 was too skinny in front, but look at that massive treadwidth (more than the Goodyear 275 width)!

data below is in the fomat: tread width/weight/rolling diameter

Potenze RE-01R:
235/40-------8.5 inch/27 lbs/ 25.4 inch
265/35 ------9.6 inch/29 lbs/25.3 inch

Goodyear GS-D3:
245/35-------8.2 inch/24 lbs/24.7 inch
275/35-------9 inch/27 lbs/25.3 inch

Yoko Advan AD07s:
235/40-------9.1 inch/26 lbs/25.3 inch
285/30-------11 inch/28 lbs/24.8 inch

Unfortunately, Tire Rack doesnt list tread widths for Michelin PS2s, Kumho MX and Dunlop Direzza Z1.

 

IMO Rich, you are WAY over thinking this decision. If you were in the battle for the title in the ALMS series, it might be a bigger deal. Simply put, I doubt you'll notice the difference between any of these tires unless you are competing and/or logging (i.e. logging lap times on a road course).

 

right on.

neova or re01r

 

Well, the Profil 5s arent ready to mount yet, so I have nothing but time to research

I do agree with you though. Basically I'm trying to find a top quality street tire that will maximize my contact patch. It's damn hard finding something that comes in ideal sizes front and rear for an 18x9,10 setup. And it's compounded by the fact that the measured treadwidth doesnt necessarily correlate with the rated sizing.

What can I say, I was a Mathematics major

 

Rich,

I'm no track person.. but I had PS2 at the dragon and was pretty happy with them.. I was running kind of big/tall 265/40/18s. But it sticked to the road and fitment wasn't too bad. But the tire didn't last too long..

However, I'm also going to go with 295/30/18 PS2s and they are arriving in next week or so. I also have 315/30/18 Pirelli Assmo and once the blk FD is ready, I'll let you know how they feel. But just by weight, Pirelli's are SUPER light! I think it weighs less than the 265/40 PS2s I had. I also have 285/35/18 Bridgestone RE050A, And these are heavy as ****!... I'm just trying to see what will work the best on my FD.. Luckily all the wheels and tires will work with RX8 and the FDs.

 

Don't know if they have the sizes that you would want, but I almost bought Dunlop Max Sports. I think for a general street tire it would work very well and it isn't terribly expensive. Supposedly (depending on the review you read) it is pretty well balanced with wet and dry traction, good hydroplane resistance, as well as decent noise and tread life.

 

Toyo Proxes R888's 255/35/18 285/30/18 <<<<Best dry weather tire on the market.

Maybe some Dunlop Z1's, they've done very well in testing against the RE-01R's and AD07's, but are considerably cheaper. They're available in 235/40, 245/40, or 255/35 for the front, and 275/35 for the rear.

Its a street car so the closest he'll get to an r888 is with the Advan AD07 and still worlds apart in the dry.

 

I may actually end up getting these, I'm seriously considering it. Thanks for the pointer

 

Glad I could help. I'd just learnt of them recently too, and hadn't seen much/any talk of them on the forums, so I figured it's probably not well known that they're out there and that they're that good.

 

Hey Rich,

Can't really help with Tire choice because it's just too darn relative. For your purposes I'd go for a good value tire that meets your minimum requirements for "performance street driving".

I can however offer how i would run this setup:

Here's priorities for me:
1. Tire Rolling Diameter = Stock

2. Retain some sort of balance front to rear without having to adjust suspension and alignment to force its behavior. Yes this means either going symmetrical or getting as close to this as possible.

3. This might be lame to some people but it is another factor. Retaining symmetrical tire shapes from front to rear. I don't like seeing a stretched tire up front and a bulgier look in the rear. just not for me and I want the tires to react similarily.

So here's my logic:

1. Because you're like 7mm off the "ideal" 9" offset, you need to compensate by running that much thinner of a tire. You are acheiving that with the 235/40, very minor stretch on the 9.

2. Since you're limited to the 235 up front i'd go with a 265 in the rear to retain equal tire diameters and tire shape. A 265 over the 10 will look very similar to the 235 over the 9. I've run this setup on my E34 M-Sport.

Now, why hesitate against the 265? Too much power? Well then just get a stickier tire. I still think it will be "faster" per say because it should be a better balance.

On a side note, I am confident you will have to roll the rear fenders with anything larger than a 275 width. Please keep that in mind.

If you wanna go wide in the rear then get a small wide fender for the front and roll the rear fenders normal style. Then run a 255/35 and 295/30.

Remember wider = more gas. ...... lolz.... Wider used to be better, now wider can make ya go broke. damn fuel conscience, didn't even know i had one before.

BOL,

Rishie

 

how about the new Yokohama S.Drive's they seem ok and prob what i will go with but still not shure

http://www.yokohamatire.com/TireSizes.asp?TireID=900

 

It's a 300 wear rating tire, so it's in a lower class than the tires being discussed here.

 

In my opinion, won't give the traction I'm looking for.

 

I'm a little late chiming in

I have a set of Toyo T1R tires. 245/45/16 on stock FD 8" rims. They just don't seem very sticky to me, and they are lasting too long. I don't think they would satisfy you, since they aren't really satisfying me

 

I pointed these out at the start of this thread...

 

That you did, thanks to you as well

 

Federal 595RS 235/40/18 and 265/35/18 put you at 25.1" all around, 140 treadwear and run $606 from citytireonline.com

 

Okay I got all this. However my quest is given the fact that my R2 is a stock suspension all the way around and I got these Ramy rims....(see thread) 8by17 and 8.5by17 what size tire would you guys go with. The brand is pretty striaght forward given this disscussion. I am an old man and I drive like one but I am going to the Dragon Tail that Phil is doing this year and wanted to get something that supports that event and will do well in the rain. I am thinking that 255/40 and 245/40 maybe a bit much.

what would be your suggestions??????

 

Doc, why do you think the tire sizes I recommended in your other thread are a bit much? Those are the proper sized tires for those sized rims, period. Those are the exact size tires that Mazda mounts on those rims from the factory .

You're in luck, this is a phenomenal tire and it comes in the sizes you need:

See ya at the Dragon!
