Hoosier A6's...

sixpax · 07-09-2012, 06:19 PM

... I know you can fit 245 front and 275 rear on the 18" stock rims in streetable tires, but would Hoosier A6's fit on the stock rims alright safely ? Be 245/35/18 front and 275/35/18 rears ... I am fairly poor so was hoping to just use two sets of stock 18 rims with some A6's on one set and a street/track tire on the other set to keep costs down.

With Hoosiers I would push the front tire up a bit more. Is this for track or auto-x? I would try and go more towards a 265 or 275 on the front maybe as much as 285. Definitely 285 on the rear min.

I hear you on the fatter rubber ... but would have to buy two sets of aftermarket wheels to handle the wider tires size. Was trying to keep two sets of stock 18 rims and run as fat as I can, safely, on them. I think Doran is running 245f/275r and they go pretty fast.

But because this would be a few sizes up from stock tire size, was wondering if under track stress, if they would be safe.

Correct we run 245 f and 275r
I know some teams sell their used tires after weekends but they are not as sticky as the As or Rs..... But more durable.
If you gotta stick to those sizes .... You gotta do what you gotta do.
Keep in mind we Are also 2900 lbs.
Once the cars get above 3000 lbs there wear rate increases pretty fast.
Auto x or track?

Track ... right now I am just running the stock 225f/245r tires on stock 18 inch rims ... BJ do you guys have 19 inch rims or 18 ?

you would want R6, not A6

M.Bonanni · 07-09-2012, 09:38 PM

^^^What he said. You will probably have to replace A6s every track day. Not to mention their performance will fall off after the 3rd lap each time out. They really should only be used for autocross or time attack. Another thing to think about, unless you are on upgraded coilovers with really stiff spring rates, slicks aren't going to be your best bet. Your suspension will be too soft to really take advantage of them. I would honestly go with a sticky street tire like the Hankook RS-3. They will last longer and will be better matched for stock and/or most off the shelf coilovers. Just my $0.02.

cossie1600 · 07-09-2012, 10:34 PM

I agree. Except R comps always helps, even on my Prius.

Keeping costs down and going to Hoosier seem like an oxymoron

... and a great .02 it is

Ark DT-P coilovers are pretty firm as compared to most. 12 front/11 rear

...not having to buy two sets of aftermarket wheels would be a significant cost savings in my book.

Couple of things

You have no worries getting 275 to work safely and properly upfront and 295 in rear.

Let's talk about proper tire for track days. I'm a huge fan of Nitto Nto1 DOTR tire. They will last longer than true slick and give great performance.

Let's bust some myths. Hoosier a6 while an AX tire compound holds up remarkably well on track. And while I wouldn't use on a hot day perform very well on days when temps are below 75 degrees. I get 3 track days from mine. However unless you're doing time trail on cool day I'd go with R6. But frankly even r6 is overkill. Don't forget if you are determined to run a dot r slick GoodYear and BFG make Tires that offer similar or even better performance to Hoosiers . A6 falling off after 3 laps? Well yes but that's falling off from crazy stick to just awesome stick. We ran my car with A6 with grand am driver driving and me in passenger seat 3700 lbs of car and people and the tires performed remarkably well entire session. But having said this I was there doing time trial so and wanted very fastest DOTR tire I could run .

If you want cheap race slick go to used race tire sellers and pick up take off slicks. That's the ticket to budget track day fun! Hey get continental (hoosier) slicks that's the ticket!

But truly look at Nitto Nto1 or Hankook RS3 they will last the longest and are less likely to puncture.

But we all have offered lots of advice without really understanding your intended use or car setup? That's where we need to start to have productive conversation. What track when do you typically run (weather) Remember a6 isn't any good in the rain! Lol! Autocross? Time trails? Suspension setup? These are some of variables to consider. Hoosiers love a ton of negative camber is your car setup to make this adjustment?

And to be real honest forums are often worse place to ask tire related question. Call a reputable race tire shop and talk to person about your application. In fact talk to a couple and you will learn a lot. Hey I even talk to technical people at tire manufactures sometimes

Some great input...thanks.

I am not the greatest communicator, so my question could probably been written better.

1. I want to keep the 18" stock rims.

2. I know for the street the biggest tire you can get on those rims is 245 F and 275 R.

3. Driving on the track puts more stress on tires than driving around on the street, so basically my question was are those sizes safe for the rims in question being they are upsized a couple sizes.

ChrisSlicks · 07-10-2012, 10:50 AM

245/275 with NT-01's should be fine. I also second my recommendation for these tires, they wear well, have predictable grip and the handling characteristics are somewhere between a street tire and a race tire. Just remember that they take a little longer to warm up than a street tire, and in this warm up phase they have less grip than a street tire, especially in lower track temperatures. I run 275/315 NT-01's on 9.5/10.5 18" inch rims.

cossie1600 · 07-10-2012, 11:21 AM

are you planning to drive to and from event on a6's? how are you not buying two set of wheels to start?
