Post Yokohama AVS Sports

OK, I am gonna take my Marlboro $$$ and buy myself a set of AVS Sports for the RS. I gotta get rid of those stock tires!

Anyway, I have pretty much made up my mind concerning which tires to get... But before I do, does anyone out there have any experience with them?

I would be using the car for just "normal" driving, not racing or auto-x. I have the extra $$$ and want some damn good go-fast tires.

So if anyone can offer some advice and/or experience..I would appreciate it. Oh yeah, I am getting an adjustable rear sway bar from Rallispec too.

I think the AVS Sports are great tires. I run them on my RX-7. Very predictable and quite grippy. None of the tread squirm like the SO-2s. However, I'm not quites sure that such a stiff sidewall'd tire is the best thing for the Impreza's strut suspension. Esp. in low profile sizes. My experience with the 215/40/17 SO-2s was that the car would ride on the shoulders under hard cornering. This would make the car's break away characteristics rather strange. I think the same would apply with the AVS Sports.

I have run both the SO-2 PP and now the AVS Sport and right now the AVS sport has more squirm than the SO-2 ever had. But I run 215-45-17.

So you would really (if you were in the market for new tires) run the AVS Sport ahead of the S02 Pole Positions?

Care to elaborate Im buying new tires in the next few weeks

thanks

I've got the SO-2 PPs on my 951S (944 Turbo S, second set too) and TTOversteer has the AVS Sports on his RS, guess what the Porsche is getting for Xmas? Yep AVS Sports, they are IMO equal to the Michelin Pilot SX MXX3s in the dry (I had those on the Porsche Last) but they will last longer and be much better in the rain. The stiff sidewall does wonders for the RS handling especially with stock suspension. RS Drives like a completely different car.

The SO-2s are great for the street but the sidewall is too soft and the tread squirm when new is quite a bummer. The AVS Sports have NO TREAD SQUIRM (WRX-STi your commment comfounds me) This was in evidence in an Autocross where I took first in TToversteer's car when the AVS Sports were 2 days old, oh I was in STS.

Suffice it to say the AVS sports are VERY impressive and I have had the lot of the expensive impressive tires. These are the best yet.

For more info do a search on "tire question?" and see my review of the AVS sports there.

Pilot - What sized tires are you running. The SO-2 PP Sidewalls are very stiff if not one of the stiffest. They had a hell of a time getting the tire to seat in the rim. The squirm I got with the AVS was on a turn I usually take at about 70mph where the SO-2 held steady the AVS started squirming. I'll see and get a good feel for them at the next autocross. But too bad at autocross I'll be lucky to hit 50 mph.

Both good tires. One nearly double the price of the other (17s). For the money, you get a wheel protector on the SO2 but thats it. AVS sports are great, I've been running them in 225/45-17 for 8 months or so. Now I switched back to 16" and pilots. But, I also just got SO2s form my M3. From what I've run on my brother's rx7 with them, they are great (he has 18s though). Really quick response and comfy enough for bad road use.

So FWIW, nearly all the tires have comprable limits, the SO2s are just better at telling you how close you are at the limit. As Shiv said though, once you reach the limit, the behaviour is a little odd. This I also found is true of the AVS sports except that they would slide more smoothly out of grip than the SO2s.

WRX-STi,
I run 225/45/17 front and 255/40/17 rear on my 944TS. TToversteer is running the AVS Sports in 205/55/16 on his RS.

Anyway I find that the SO-2 PPs are not as stiff as the Pilot SX MXX3s I had last but since they are superior in the rain I bought another set, also I bought race tires for AutoX so I was able to sacrifice some all out performance for street livability and bad wether perofrmance. With the AVS Sports I don't have to do that. That is why I am putting them on next.

Also I find with the SO-2s that the steering weights up in an unaturaly heavy way as steering angle is increased. The response is not linear, rather annoying trait.

Also how many mile were on your AVS Sports before you did your test on the turn? Tires take a few hundred miles to get all the mold release out of them. Also the SO-2s when they get past half tread really start to get sticky cause you have uncovered most of the sticky rubber by then, and the tread is very stable when it is half worn. I don't think even the AVS SPORT when it is brand new is totally devoid of squirm (contrarty to previous exageration) but comparably they are very stable when new.

Lastly what tire pressure are you using? Different tires have a different "sweet" pressure.

I've autoXed both tires and by my experience the AVS Sport is definetly the better tire for competition use.

EDIT: Bassem The AVS Sport also has a rim protector.

Pilot,

I am not sure about the rim protector. I had mine in 225/45-17s with no protector. Perhaps select model sizes do indeed come with a protector, but mine did not. I even had a pic of them in the members section, which I guess is gone now. I guess all one needs to do is ask wehn they order anyway!

I love yokos in general anyway. I probly would have picked hem up for my M except that I just needed to get a good rain tire with good dry grip and comfort that had a rim protector (each of my M3 wheels costs nearly double what an RS wheel does). Which is basically what he AVSsports are except for the sidewall strength and rim protection.

Pilot - Your probably right, my AVS Sports are brand new with about 500 miles on them, not autocrossed yet, and my SO-2 went to the autocross the day after I put them on so that wore them down to the sticky part pretty fast. Well we shall see in one week.

I am running 50 psi.

I have autocrossed all my tires, I haven't missed an event since I got my car in Dec. 98'. So right not I'm in the process of trying out all the tires available and sorting out the best from the worst.

For everything, from what one of the Autocross experts out here said that all the ratings on a tire are made at the MAX psi on the tire and he runs all his tires at this level so I figured that I try this out.

That's not a good idea IMO. Mark the shoulders and if you're not past the edge of tread, lower the pressure.

The ratings on a tire on not made at MAX pressure. They are made at roughly 36 Psi.

(See I did get some useful info out of that Michelin engineer)

Do as Colin says, chalk the tires and bring down the pressure until you are using all of the tread.

36 psi??? thats way too low.. the tires look flat with only that much pressure in them. The wear indicaters are almost perfect right now. Anyless air and I will be rolling over.

It depends on the tires, I ran 36's all around with my Nexuses & there was no wear on the sidewalls whatsoever.

And yes, I was pushing it!

WRX-STi, maybe you should invest in a better pressure gauge? At least borrow someone else's for a second reading. 50 psi is a bit too high! Even for the auto-x! I'd drop down to about 38F/36R if I were you.

I'm not saying to run with 36psi I'm just saying that the MAX load capacity is reached at 36psi. More pressure will stiffen the carcass but won't increase the load capacity, so same load capacity and better handling.

However at too high a pressure the handling goes away because you are decreasing the contact patch area. IMO 50 psi is too high for proper performance.

Question

Anyone consider running 205/50 Pirelli Asymetrical (sp?) tires on RS? I spent some time looking at the Tirerack online reviews. It appears that the Y rated tire is as good as the 02 or AVS Sport. And better than the XX3. The upside of the Pirelli is the sizing 205/50 as opposed to 205/55.

Any thoughts?

Joe

I've considered them, but perusing some of the other car clubs online *ahem*, I couldn't find anyone that thought of the Pzero as the MXX3's better. Most didn't even think it was equal. Additionally, I don't know of any national-level STS competitors using the PZero, they run mostly the MXX3 and some have the BFG KD.

...But I personally haven't written off the Pzero just yet. Not quite time for me to buy tires yet, so I'm sitting on the fence.

Bringing the question back about Yoko AVS Sport, I just ordered a set of 205/55/16's for my RS.

Does anyone know how they will hold up on the track? Im going to my first race at the road track in July, and rather not drive these tires on the track if im just going to trash them. I kind of payed a lot of money for them and would like them to last as long as possible :-)

I was thinking of just running my RE92's on the track and just killing them. That way I can mount a set of slicks on the stock rims for the summer and winter tires for the winter.

Thanks.

I just got back from running the Mirrorkhana and finished 2nd in STS on the Nexus. I ran 47/37. To give you an idea how fast the course was, I glanced at the tach as I crossed the finishing line, 6,000 rpm in 3rd gear, roughly 74 mph! I think a dedicated set of R compound tires and rims would be the ticket for the track. My Nexus is suffering from blisters on the outer tread blocks. I don't think I will get 5,000 miles out of the set with roughly 10-12 autox's.

You got it Colin. I was going to say the same thing. If you guys look at some of the Pro Solo results. You will see that most people run the Pilot MXX3.

Gary, you're just brutal on tires. I think no matter what you were running they wouldn't have lasted more than 5k miles and 12 autocrosses.

Were the front and rear blistered or just the front?
