Default Azenis 205/55/16 AutoX Pressures?

Tried to search, but I could only find pressures for 17's.

I'm new to autocrossing, and I just got some new Azenis Sports, (because it MUST be the tires that are slowing me down) and was wondering what sort of tire pressures people are running for AutoX?

Also what changes do you guys make for rain/wet conditions?

I'm running DS in an 03 WRX sedan.
Thanks for the advice!

I'd start out around 38 psi.

Mark your sidewalls with some chalk, and see how much you're rolling onto the sidewalls. Up the pressure if needed.

With autocross, you never get the tires hot enough to be worried about percentage increases between hot/cold tires. What you're really concerned with is making sure you're not rolling over onto the sidewalls.

Have you ever driven on Azenis? Cause I sure can get them hot enough to need pressure changes. On a hot day I can be 7+ PSi higher then cold. And I have seen noticeable performance changes at test-n-tunes with 2 PSi differences.

As far as a starting point, I usually start with 46F and 42R. That is with 215/45/16s however. I have run as high as 52PSi and as low as 30PSi.

Start at some point around 40 with about two PSi less in the rear. Use the chalk to figure what you need.

Someone who know alot more about this then I do once told me to start with the max rating of the tire and use that as the low tire pressure. Then use the Factory difference and figure the high tire pressure.

You cannot run 17 inch wheels in DS. You say both 16 and 17 in your post so I'm not sure which you really meant.

I start w/ 42 fr, 40 rr. I am still experimenting though. And autox in TX will get your tires pretty warm. Azenis will get a little greasy if they get too hot.

Question

Anymore updates on this ? I ran the first race of my 205/55-16 Azenis last weekend with 41/40 and let me tell you,they felt worse than my RE92's ! Howling and pushing like crazy.Car is a WRX sedan,weather was hovering around 65-70 cloudy. Didn't really see that much sidewall rollover but then again I didn't use chalk.
I probably have to bump the pressure up.

Were they completely new? Tires can be slippery for a couple hundred miles because there's mold compound on them. They will also get slightly better once they're partially worn. Your pressures sound very reasonable. But in any case, they are worlds better than RE-92's. If they're pushing like crazy, you're going too fast.

Not exactly on topic because I have never used Azeni's, but I run 38.5f/53r using Toyo RA-1's. The front pressures worked for all weather conditions, whereas I would lower rear pressure to gain more grip in the rain.

They were brand new. I drove them to the event ( to try to break them in) which was about 90mi. one way.
That and I may have been going too fast.
Thanks !

I run 46/43 ... with 225/17/45 Azenis ... when I tried lowering my pressures ... to the low 40's, high 30's I had roll over ... with 17X7.5 wheels. Lately I've been the fastest Suby in our area ...

If you are plowing ... you aren't using your brakes well ... slow down! Then you can get on the gas earlier ... and your times will improve dramatically!

In very wet conditions ... you need to INCREASE your air pressure ... to crown the tire ... so you get more pressure on the center of the tire. Azenis are O.K. in the wet when fairly new ... but as they wear ... they aren't doing to be great compared to a good high performance street tire ...

50F, 45R with stock camber bolts maxed and 205/55-16 and the biggest front swaybar that Whiteline makes. Now I've got Cusco camber plates (set up for castor and camber) and suspect I'll be able to drop the pressures by up to 10psi. I'll know in a week-and-a-half.

Larry found the magic ticket; the big front sway.

I run 40,42 daily.... If I'm doing autox or hitting the canyons I START at 42,46.

- Just so you know... RE92s w/20lbs of air on a 2.2lOBS wagon in the RAIN will own you on the down/up hill.... Especially on Ortega Hwy. Unit91's old car...

I have had luck with 38-41 up front and 34-36 on the rears. 16" Azenis. I can't remember, the exact tire size, but they are the ones with the larger sidewall #. I felt I was plowing more when the tire pressures in back were higher. No roll over...checked it w/ chalk.

The slalom becomes a bit trickier, but I feel I can carry more speed around the corners. FSB will be key next season. Oh and take advantage of the "street tire" Pax and classing if you have that available. It will make you feel better.
