ad08 or re11
 

Hello guys,

I know there have been a million threads on tires but do to my inability to find a suitable thread im throwing this out there ( pardon the searching ignorance).

After lots of track days my tires are done and want to upgrade to either re11 or ad08. I want to rid of under-steer that the car has with the stock setup ( i have the sports package).

For the re11 I am wondering what setup would be the best would running 275 square be the best bet? or run 275 fr and 285 rear?

If I can find a better price on the ad08s ( likely here in canada) I would use those as well, the tire sizes are limited and I am thinking of running 265 squared or a 265 295 combo, the latter I'm not sure if this will help eliminate understeer as it is still running the same stagger.

any advice would be greatly appreciated,

thanks in advance

If your goal is to eliminate the understeer and track, run 285/35/19 all around. As far as which compound, it's like debating between Kim Kardashian or Jennifer Aniston

I am running stock suspension will i be able to run 285 on the stock sport rim upfront?

That's what I have on the car since April

there was a comparison on tirerack.

soooo, which one's more like Kim K? :happydance:

:iagree: :D

From my bias view, I would love to say RE11 is Kim since I have it :)

but the treads are more curvy and sexy on the AD08!

me too I love my RE11!

285 square sounds great for the track but do you notice any tramlining when driving on the highway? In addition as I am new to the tire buying game what sidewall height should I get on both the front and the rear?

285 all around your car will def track the road. i run 285 all around for the track and ill usually put them on the car a couple days before just to make sure they are still balanced and what not. the car LOVES to pull. i let my buddy drive it around a parking lot and he tried convincing me my alignment was off. you have to be very alert w 285 on the front.

As for sidewall, are these going on the stock sport or base wheels?

These will go on 19 inch sport rims, so the 9 inch front rim should be able to handle the 285 width tire?. Is the pulling that bad that it makes driving difficult? The roads here in Quebec are bad so just want to make sure it's safe to drive.

its the tire compound that is causing it, thats what r comps do on the road

i ran 265 last year, it really makes no difference as far as highway drives, maybe more road noise. i would look into putting more toe in if thats what you are concerned about. i had my alignment done at 8k and i found my toe to be out. car drove loads better after.

I had problems w 275's on my firebird with tracking the road. and they were a crappy tires. Im not concerend about it. I have two sets :tup:

Alright so I will look into the 285 square set up thanks for the advice and I will see how much the car will track, will keep my hands on the wheels at all times no lazy one hand on the wheel on the long straight highway drives!

Day off so been doing further research and finally found an older thread where u commented cossie on 285 square or 265/285 combo. You said the stretch might not be as safe as 265 on the front. Have you been running 285 as a daily driver or only using your prius, as my car is my daily driver in both summer and winter( with winter rims and tires). Does this change the picture? An would you then recommend the 265/285 combo? I'm sure this will already decrease the understeer but not to the level a square setup
would.

I see also that ad08s can be had in 275/35 would this setup be safer to run square? It would also be a little cheaper.

If you care about going fast, go with the 285 all around. If you are just learning, go with the 265/285 to be more conservative. I am actually getting better wear out of the 285 in the front because my car isn't plowing as hard. I made the mistake of stagger because there weren't many people that can give good references when I first started with the car and I was trying to be too conservative, the novelty wore off after about a month of driving.

I have nothing against the AD08, I just don't like the size they offer. I like the 285/35 for the taller sidewall and a little wider footprint. Regardless, all these freaking tires are expensive and you can't go wrong either way. I think this is my last set. I have a trailer hitch now, I am going back to R comps next year. F these $340 tires.

You can check some of my track videos from this year vs. last, you will see the difference in steering input by just changing the tire size.

Where can I find your vids cossie? And your tire wear is better that's surprising but good to know and no problems running a 285. I read the re11 is less wide than other 285 widths so I guess that's why it works because my research shows that mist people ins that tire size is a bit too large for a 9 inch rim.

i will link you when i get home

285 is definitely not recommended on a 9", but you got to do what you got to do. i couldnt drive the car with the plow i had, my prius was more tossable than the z. the problem will only get worse as you wear the fronts out.

the autox guys run 295 on them, i am sure some has tried 305s

if someone wants to donate me two 19x9 wheels, i will pop the old 265 on and test the speed difference vs the 285f

It's hard to "see" the plow, but here is a video autoxing last year on 265/285 vs 285 all around.

I don't know how much you can pick up from track videos since they are different track, but here is a video from last year vs. this year.

hmm can you run square setup AD-08 295/30R19 with nismo rims? 9.5" front and 10.5" rear.

My RE-11 almost finish and thinking to try AD-08 now.

Not really a debate...

Kim!

What do u mean? Will I be alright? will it rub? :confused:

No, just do it

I would go with Kim Kardashian only because she is younger.
