ok... I have the

Pirelli
P 265/45 R17 84V

^no idea what that means BUTTTTTT

I was doing some spirited driving... and didn't here any skreeching from the tires.... is this normal?

-Josh

 

That's probably because you weren't moving! The width of the tire would probably contact the suspension and the outer fender well. I hope the 265 was a typo. :smile:

 

on your cooper-s?

you can't fit that, can you?

P 265/45 R17 84V

 

Maybe you should try driving a bit more spirited. . . ?

 

absolutely no way! , unless you do a widebody :D

 

i will go check again... and bring a flashlight...

hrmmmm
ok ok ok

its 205.... not 265

and my def of "spirited drive" is spinning wheels through 1st gear and then a bit into second gear.... and no skreechin just the sound of the tires spinning too fast without moving...

-Josh

 

Let's start a pool. What does he really have? I guest 205/45-17. :smile:

Steve

 

Just go faster and turn tighter, they'll screech. :smile:

Steve

 

Get off the dirt road and onto some pavement

 

So i am guessing from the semi-smart/funny replies... that this isn't normal... I am not new with spirited driving in higher performance cars. Its just that I feel like something is wrong since they don't make a sound I just get to a point and boom... my rear end is sliding without any real warning

-Josh

 

Maybe you have lightened up the rearend too much and it's breaking loose for lack of traction? No suspension mods?

Steve

 

all stock except for no rear seat... and new dial faces... but I do have a 1/4in sheet of AL inplace of the seats weighing in at about...10lbs...maybe 15ish..

Its just a bit scary when your sideways on a city street... like WTF!

-Josh

 

The front end doesn't slide? Are you braking when the rear gets loose? Or does it come loose under power? I'm no expert with front drive, but I have had a lot of experience with rear engine, rear drive. My guess is if you are losing the rearend and have plenty of grip in the front, you could gas it and pull the rear around behind you.

Steve

 

The sliding is the least of my concern...its the no warning sliding... does the no noise coming from tires mean something wrong or something that I will have to get use to? I just don't want something wrong with my tires and continue to drive spirited and have something majorly wrong happen to them or the car.

-Josh

 

Well, I don't know how you drive or if those are the stock runflats, but there is usually some indication (feel) that they are about to go. Or if you run on the hairy edge all the time, then anything like a little sand, oil or water on the road is going to get you. City streets are not perfectly clean surfaces so you have to watch out.

Steve

 

Make sure they are not over-inflated. That will definitely make them slide easier.

Steve

 

Being my last post for tonight... its WAY to late...

I drive with ASC off all the time (that should tell you something)... and even the tires are stock. If tire won't give me any sound feedback I will have to adjust; if it sounds like something is wrong with them... PLEASE let me know.

-Josh

 

Josh,

I hope you are not driving on public highways when you are spinning your wheels thru 1st and 2nd gears and getting sideways.

Is this your first front wheel drive preformance car? When you say the rear end slides without warning just what are you doing when this happens? Are you accelerating thru a corner or are you coasting or on the brakes or a sudden lifting off the gas when it happens?

If you are lifting, you are the cause of the slide. DON'T DO THAT!

If you are on the brakes in a corner, you are the cause. DON'T DO THAT!

Some tire are more communicative than others. If you are waiting for audible signals from the tires I think you need to make an adjustment and learn to feel the car and what it is telling you thru the steering wheel and the drivers seat about what is happening. The signals are there, you just may be looking in the wrong spots for them.

Have you checked the air pressure in the tires? With run-flats this needs to be done with a pressure gauge at least once a month. You can not see underinflation in the sidewalls as you can with conventional tires. Make sure the pressure is set to factory specs.

Better yet, enroll yourself in a driving school at the nearest local track or find an auto-X club in the area and do you "spirited driving" someplace safe for the rest of the population.

 

You sound like you were sitting in the passenger seat with me... I must be doing EVERYTHING wrong... time to go to driving school! But I am really happy its not a mechanical or tire problem... and that its me!!!!

-Josh

 

you might want to double check your tire pressure... could also be a cuplrit... may not be the reason, but may have helped it
