its been a while, it all happened after the mess i had with my tire change (see old post). Now im running the Pirelli P7000 (ultra high performance tires), 195/50/15 front and 205/50/15 rear.
i dont know if this was caused from the tires, but, the car behaves funnily, when i turn the steering wheel there is a delay in the car to follow, it feels like im driving in the wavy sea. it does not feel like the car i used to have, and i tend to forget those good old days i had an excellent handling car.
in answer to your questions, yes, the tire pressures are correct, as recommended by Toyota, wheel alligment is good, and the tires as i said are new. Plus the shocks were checked as well and were all found to be good.
help me get my car back.... s:cry: :cry: s:cry:
*UPDATE*
i went and had an MOT check yesterday, so they checked the shocks as well. i was surprised to see that my shocks, the front left was found to be 30% and the right 43%. The rears were found 50% left and 53% right. I f you noticed in my old post, the shocks were found to be OK a couple of moths ago...
The guy at the shop said that t plays a big role that it is a light weight car, thats why the shock results were so low, but the 30% shock was more than likely the problem.
The thing is that i never noticed that problem, only after the tyre change. Is that a coincidence or its both now, crappy P7000 tyre choice and the shocks as well.
The car is becoming undrivable day after day, and i would consider it as dangerous to drive on speeds above 70km/h or even worse on trying to change lanes or overtake a car.
Any suggestions welcome. Mind you that i dont wanna spend more money on a car that im planning to sell as soon as possible...
Thanks
btw, im planning to sell it soon and get the S2000, but seriously, i cant sell a car that behaves like that on the road
it's your tyres
Quote from: "markiii"it's your tyres
so markiii, you reckon its them? s:shock: :shock: s:shock:
how come? it cant be that crappy tires and be sold that expensive in the market.. i got them for £85 in our market each,( dont ask me why ive chosen those) at the time that Potenza or Michelin are cheaper s:roll: :roll: s:roll:
Jesus that means that i will ave to spend another fortune now in buying 4 new tires again?.....
i just hope you are wrong and its something else... s:( :( s:(
exactly teh same issue I had when I tried Eagel Venturas
they may have realy soft sidewals, I'd try increassing you pressures and see if it helps

Are you sure about that...? Last time I looked at Pirelli's, the P6000 was the grocery getter tyre, P7000 just a bit better, P8000 was supposed to be good and P9000 a high performance tyre s:? :? s:?
thanks a lot mate s:wink: :wink: s:wink:
Pirelli UK list the P7000 in their ultra high performance category alongside the P Zero's.
I'd go with mark's theory about soft sidewalls.
Soft sidewalls sounds about right and trying different tyre pressures sounds worth a try to me.
If you're planning to change the car, no problems wtih part-ex!
Also just found on the Pirelli site that P7000's are directional. Have you checked that you've got the correct tyres on the correct wheels???
Also from Pirelli's site. I tried seeing what tyres they recommend for the Roadster. They recommend P6000 or P7. But they also seem to recommend the same tyre for all Toyotas I tried!
based on teh proxies which also have softer than stock sidewalls, try adding 2 PSI to each corner.
If they are as bad as teh venturas you may need to go as high as 40 on the rear.
oh and one other thing that may be a cause if your local tyre place/MrT are really stupid, (They were for me)
check that you have teh correct wheels front and rear
front should have 185/55/15 tyres on 6" rims rear shoudl be 205/50/15 on 6.5"
look on teh inside of teh wheel spokes (you'll need to take teh wheel off) to check,
205 tyres on a 6" rim at the back will defo cause thsi feeling.
correct tyres are on the correct rims, and with the correct directions. That was one of the first things ive checked s:wink: :wink: s:wink:
whats left is to give a try at different pressures....
thanks s:wink: :wink: s:wink:
bump
? did teh pressures thing not help?
Quote from: "markiii"? did the pressures thing not help?
nope, by adding pressure the problem got worse..
anyways i will more than likely go on the changing the shocks way. And it costs s:evil: :evil: s:evil: the Toyota dealer asked me 140 GBP for each shock s:shock: :shock: s:shock: i remember i replaced my MX5's shocks couple of years ago, i bought the KYB (Kayaba), all 4 costed me 180 GBP.
How did they check the shocks, to get the percentages? Last time I knew, the MoT test was just a simple bounce-the-corner and see if it stops bouncing.

exact pressures can be determined with a special equipment,this specific one was BOSCH ,FWA 515, Battery-powered chassis and suspension tester for cordless operation. You just put your car having the tires sitting on the sensor, it vibrates and gives you the exact percentage of wear.

TBH bud all this testing will prob be costing you more than a set of tyres and even if it isn't the tyres you'll have a good base to start from!
Silly question but if its a road you drive every day have you tried it on other road surfaces, it makes a HOOOGE difference to my '2 anyway!
