I'm a bad boy...

[Mark The Cabby]

Fair enough!

I prefer Michelins in the wet, because even though grip is marginally less I am far quicker on the Michelins than I am the Goodyears, simply because the Michelin has better subjective feel and better progression and on the limit handling characteristics. I prefer to be able to feel where the grip is and when its running low instead of having more grip but less feel.

F1AS3 is available should be exceptional. Also Conti 5P/6P are superb wet tyres as well and the best wet tyre by miles is the Rainsport 3, it completely destroys the F1AS2, 7s a lap faster on track in E46 M3 compared to F1AS2 in wet conditions. Infact the rainsport 3 is literally just 2-3s a lap slower than wet slicks, hugely impressive wet tyre.

On checking the good year website I seem to remember that the rears were not yet available in as3's but the front were so I might look for them...

Agree on both MPSS and Rainsport 3 fronts Gibbo!

Speaking of which, are you still on standard rubber on the GT for the moment?

May strip and replace from the get-go and sell the Pirelli's.

Drop Goodyear an email, ask if the rear size is available or available in any other regions. Better to get AS3 all round if you can.

Yes I dislike the Pzero but I am not gonna throw new tyres away, in the dry they OK and in the wet/cold as long as your smooth and expect them to be poor you will be OK.

Remember this when you get your car it shall be warmer, the Pzero's weakest point is traction in cold wet weather. In warmer wet weather and with a bit of heat in them (31-32psi cold, get them upto 35psi) they are more predictable and work a bit better.

Survive the Pzero's and then when you change to Michelins be like a handling upgrade.

DO NOT MIX TYRES, you'd be better off just sticking with Pzero's rather than mixing brands front to rear, it will handle aweful and be a potential nightmare in the wet.

I dont get that. If the main problem is the P zeros losing grip, what would changing the rears only mess that up. Dont make sense to me.

You really don't get why it is a bad idea to run different brand/model tyre on front and rear axles?

Come on it is just common sense.

Think about it, he wants to change the Pzero, due to lack of grip in the wet, that lack of grip in the wet is present on all 4 axles, people are losing the rear because they are being to heavy footed with power application.

So now you have MPSS or F1AS2 *ONLY* on the rear, so now new found confidence to push the car harder on corner exit, especially in wet conditions. Your getting faster and faster due to how well the car is putting power down, you come to brake, instead of spinning, you simply understeer into the ditch instead because they are still the same Pzero's with lacking wet grip. The difference is the better wet tyres in the back gave you confidence to go faster and instead you lose the front-end.


When it comes to feedback running mixed tyres gives odd signals, when you have crap tyres all round (Pzero) you drive slow, particular in wet conditions. The moment you mix tyres subjective feedback is at best odd.

Then I ask the question its a 35-40k sports car, seriously why are people trying to skimp by mixing tyres, either drive slower and more carefully putting up with the Pzero's or buy better tyres all round.

NEVER MIX TYRES! :frusty: :frusty: :frusty: :frusty:

Ekona (I think it was you who knew him, Dan Morgan) would be so proud of you right now :lol:

Yeh, I understand what you are saying but I also feel that you deal with each issue. If a race car is getting loose on the rear end, they try to dial out that issue. You ofter hear them talking about sorting out over-steer or under-steer.

I am not sure that sorting out a traction at the rear issue would make me want to corner faster. I am pretty sure I corner well within the limits of this car anyway.

Having said that. I would change them all round anyway. I don't like mismatched tyres and I agree if I am going to improve the rear I may as well improve the front. I am just not convinced it would be dangerous unless you are someone that drives at the limits.

The wheel spin people are experiencing with these cars is just normal driving, not 'spirited driving'

I think you're over-thinking this a bit where the average Mustang owner is concerned.

Ooh boy I'm in for it now...

Not really its a sports car, its not the 1.0l run to the shops car.

But hey if owners are happy to compromise the handling balance by miss-matching tyres it is upto them, but its absolute stupidity, sorry to be blunt but its true.

Agreed some owners who just potter, never push the car may not notice, but you want equal grip, equal handling characteristics at all four corners.

Then if you want to talk about balancing a car you do it the right way, just like a race team, anti-roll bar settings, tyre pressures, ride height settings, alignment settings.

Not one race team on this planet runs miss-matched tyres, if there were gains by doing so for balance reasons and lap times they would, the fact they don't explains why.

Sorry if OT but we all have 30k+ sports cars, its not a 1.0l shopping cart, its a powerful RWD car and the last thing you want is to upset the balance or get odd handling characteristics due to poor tyres or miss-matching.

I just wish Ford had fitted these cars with Michelin Super Sports, like they did with the 350.


End of the day if your really worried about the handling/grip in wet/cold don't drive the car. If you have to drive the car and want to be as safe as possible put it in wet mode and treat the accelerator pedal like it has an egg under it and you must not crack it and make steering inputs smooth.

 

[Centurion07]

the last thing you want is to upset the balance.

My point was that for the average Mustang owner, the throttle pedal is likely to be the biggest factor in this.

Haha! That's how I broke the news at home. "Are you building it?" was the question.

 

[Wobs]

It also depends on the competence of the driver, I've got THREE different tyres on my car (long story) I've got more power than the Mustang and I don't hang around. The back end jumps sideways rather violently at times, but no major problems

Two of them are MPSS though......

Very good, I might try that...
