Default Bridgestone Potenza S03 and bad handling

OK mates... i got these since a little bit of time now, and I have to say that I'm beginning to think that my car worse handling than before is only caused by those tyres...
How can I explain... i feel my car is a lot less "biting" the road than before when cornering hard, very less precise, less attack, direction and steering seems to be floating a bit... and worse, when cornering hard, car often will feel like it's on ice, it very quickly loses 4 wheels and begins to slip everywhere... i mean VERY easily !!!!
To sum up, my Escort Cosworth is not handling at all, now, and i want to find out why.
I got S03 tyres (3000 miles approx), perfect tracking, all new urethane bushes at front, 4 x Koni adjustable dampers, and this fookin stupid car does not handle !!!
Help

The SO3's were bought out to replace the SO2's obvioursly, BUT even Bridgestone will tell you the SO2's are/were THE best tyre from there range

Get some F1's or Toyo's Pet

they are 225 / 40 / 18 and there is 2.1 bar at front and 2.3 at rear...

Thanks Tiff But do you think that this steering floating i can feel can be caused by them too ? this steering is unprecise, it almost seems like there is a play in it ! (and pretty sure there is no play at all)

oh no, there is less than 20 or 30 Escort Cossies in the whole France, and finding someone to lend me wheels going on my car will be harder than buying new ones

As discussed previously Pet, i dont think the So3's suit the chassis at all, and would be better on a softly sprung vehicle.

The So2's were without doubt the best tyre i ever had the pleasure of using Sadly, their replacement is somewhat lacking

Pet,

The SO3's were reviewed in Evo magazine in a tyre test & did pretty damn badly considering they were one of the most expensive. They actually had the best outright cornering grip but the testers felt they were VERY nervous & snappy & were particularly bad in the wet (worst of the lot).

Incidentally, the Goodyear Eagle GSD3's won the test overall, think Toyo's came 3rd or 4th.

Cheers,
Ian

Yeah Stu, remember what you said Just wanted to have other ppl experience, cause i really am disappointed lately.
When I bought it, it had Dunlops (don't remember which ones...) and handling was great. Then i fitted Falken, and it was the worse shit i ever tried.
Then i fitted S03 on my new 18" superturismos, thinking they would rule, and it's like before

I understand pet, and in 14days time, we will take your Escort to the nearest race track and beat the bitch up for all this heartache she has caused you..

Bring Your Duke.... You can take pictures from behind of the bitch squeeling and smoking her way around the Ricard track and then she will need new tyres anyway..... and we can fit F1's JOB DONE.

Hmmm just noticed the tyre pressures you're using, they MAY be a little too high. Try lowering them a touch (bit by bit) as the handling traits you're describing I have experienced when I put too much air in my 17's. I found that my car worked best at 26psi but then that was a 2wd saff (alot lighter) running 17's so I'm not sure how relevent it is but it's worth a try as it doesn't cost anything

SO3s suck big time . SO2s are still available in this country .

You have to either live with it until they wear out or replace them...

Thats that sorted then,

Pet and Stu are going to kick the living shit out of Pets Escort, ripping the shitty tyres to bits.
Then pop and get a set of F1's on it

SORTED

what i fear is that this floating in steering and sliding i feel may be a worse problem than only crap tyres.

well i can hear a kind of "woo woo woo" rotating sound... not loud at all, but still a bit there... don't know if it's a belt, or dead bearings, or anything else... this car is so noisy ROFL
Stu told me he never saw dead bearings on an Escort Cossie, so why me ?

I really love my everyday's car : a new 1.6 Duratec Fiesta '04 Handles incredibly well, very silent... this fookin Fiesta handles 100 times better than my Cossie ... and all this in a perfect comfort.

"the best handling stage 1"... this interests me a lot !!! i probably have the "worse handling stage 3" , maybe we can go one with the other ? ROFLMAO
yeah? yoko and toyos are great, so ? dunno why, but deffo hesitate to buy "exotic" tyre brands like those ones... maybe because they are too young brands, but i know this does not mean their tyres are not good !
