The Foz STi has arrived with some pirreli p7 which I think are a part of the issue with the cars tendency to understeer and the steering to feel a little light/loose so think a starting point would be to fit a fresh set of tires all round.

So what are people running?

It's not a like-for-like comparison but I have Pirelli P Zero Neros on the Impreza, and they've always been perfectly suitable.

Yokohama Parada Spec 2 tyres are also a good choice.

Goodyear Eagle F1 Asymmetric 3. Had earlier versions on other cars previous to the FSTi and can't fault them.

But then I have replaced the suspension, and fitted a larger anti-roll bar (which made the most noticeable difference), plus the drop links, and replaced the bushes...tyres were the last thing I replaced. Previous to that were some Hankooks which were OK. nothing special IMO.

I might need to do this too, I was pleased that the place I got the car fitted Bridgestone Potenzas but man they are so noisy I thought. Upon closer inspection they have the dreaded letters "RFT" on them... :shake:

So yeah, it has runflat tyres which not only are noisy as sh*t, but make for a hard ride too. The worst part is as the car is not fitted with tyre pressure sensors like RFT cars generally are. I will be having to constantly keep an eye on the tyre pressures incase I get a puncture as there is no warning.

I have Dunlop blue sport response on the mazda which are great in the wet and very quiet, I would maybe opt for the Sport Maxx RT2s on the fSTi. Everyone raves about Goodyear Eagle F1 Asymmetric 2's but having driven on the non Asymmetric's years ago on a previous car and I found them very squishy and felt the tread roll and meant there was usually initial nervous turn in and under-steer. They have probably sorted that now so probably worth a try.

The tyres I've enjoyed the most were Yokohama AD08Rs, brilliant on the track and dry road, even in cold (above 5C) weather but sketchy in standing water, been in plenty of R888 equipped cars and they are also mega in the dry.

Really there isn't much in it between most of the top brands main "all round/season" tyre so look for a decent deal, if you really want something specific in terms of performance (ie. dry or wet specific) then prepare to compromise in certain areas.

I have a set of Hankook Ventus ready to go on the Cross Sports when it arrives, due to good reviews. Ideal would be Michelin PS4, but £££s

Cheers for all the feedback. Goodyear eagle f1 asymmetric 3 and piolet sport 4 seem to be the common ones to go for.

Can someone confirm the correct size tire? And has anyone opted for something a little different

look at some fpans stuff on handling and tyres hes most informative .
just a word more about the goodyear tyres , if you have aggressive camber on the front and then do a few motorway trips they will scrub the inside also the wet grip is astonishing imo . 225/45/18 is the fsti way

Cheers mate I'll take a look. Camber settings are all standard same as the suspension. Before uprating anything I thought it best to start with the tires as I'm not to sure the tires I've got fitted are doing any good.
The Goodyear asymmetric 3's are coming in just on £100 a corner which I didn't think was to bad.
225/45/18, how about speed and load rating do I need Y's and XL's?

I know this is probably a way away from the performance tyres you are looking at, but I am a great fan of Cross Climates. I use my cars all year round and the wet/cold grip on them is astonishing. No real downside in summer either. Bit more costly though (around £550 a set from memory).

It seams that most people here are posting high performance tires. I use my Forester for commuting and road trips as a majority. Having been putting between 20 & 30 thousand Miles (not K) on a year I needed something with decent grip but didn't wear out every year.

I use Contenentals. I believe that the version I have is the True Contact and they are working very well for me. Of course I have a 2.5i so I won't be winning any land speed records but I am happy with the performance.

The reality is that any of the well known brands will be perfectly fine. The Continental Contact 3s on my Impreza 8-9 years ago were fantastic, but no doubt reviewers would say they are rubbish compared to new models.

yup definitely y 's
the only down side is their not great for fuel usage , but hell you got a Subaru if you were worried about that you would be on the green planet forum .
Thanks for that. I assume that due to the weight of the Foz a load rating of XL is also needed

Appreciate everyones help so far. Hoping that replacing the tires will help irradicate some of the light steering and understeer that the car is suffering from. After it'll be arb's and associated bits

Thanks again

Load index and speed rating is the maximum speed at which each tyre can carry a load. So unless each tyre needs to support 750kg at 186mph then do you really need a 98Y?

A fSTi weighs what 1500kg and has a top speed of what 140-155mph? Lets say the forester was 50/50 front to back your looking at 375kg per corner, a 98Y would allow you to carry the entire cars body weight plus another one on top...

Okay so lets say your hitting a corner at 186mph with two concrete filled washing machines in the boot and the car is leaning heavily on one side of the car throughout the turn, then maybe you should be thinking "maybe I should have gone with the 98Y XL's..." :lol::lol::lol:

Anything from 91V (150mph/615kg) upwards will be absolutely fine.
