Is it possible for a rim to spin inside the tyre?

Mar 07, 2005 40 Replies

Hi all,



Never noticed anything like this before so I thought I'd ask...



I've just had the front tyres replaced on my '01 Saab 9-3 Aero. It had the standard Pirelli P6000s on before but I pushed the boat out this time and bought P ZERO NERO instead. They're 215/45 ZR 17.



On the way home, there seemed to be a lot more wheelspin than I would have expected when accelerating moderately hard in second gear. It's quite a powerful car, and it's always been apt to light up the tyres in second if I wasn't careful, but this seemed a lot worse than normal and I'm sure it didn't come accompanied with the tyre-against-road sound that it used to.



I can only think of three explanations for it:-


  1. P ZERO NEROs have crap grip on damp roads.
  2. They need to get roughened up a bit before they'll grip well.
  3. A rim really is spinning inside a tyre.

They used some white liquid when they fitted the tyres. Not sure if that's a sealant or a lubricant.



Any thoughts?



Cheers,



Colin.


New tyres need running in, any good tyre place would have warned you of that. it is extremely unlikely/(impossible in practical terms) that the tyre has moved in relation to the rim. they may have the wrong pressures in.

That's favourite i'd have thought - brand new, cold tyres and greasy winter roads.

forgot to add that good practice (very recommended) is to put the new tyres on the back (unless they are different sizes front to rear)

Don't go there again. Can we just agree that is not universally accepted?

Colin Stamp ( snipped-for-privacy@stamp.plus.com) gurgled happily, sounding much like they were saying :

Sometimes tyres have "mould release agent" - motorbike tyres are notoriously lethal when brand spankin'.

It's about as likely as the driveshaft spinning in the hub.

It's a lubricant to get the tyre onto the rim, and a sealant to stop the air getting out. "Tyre soap".

I've seen it on a s**te old cav driving through Leeds. May well have been the wrong size tyre for the rim or somethign stupid given the s*it driving around that place.

The message from Colin Stamp contains these words:

That's normal. It's a water-based lubricant without which fitting tyres would be a right bastard.

I was going to say are you sure about that but realized it is until the air pressure seals the tyre rubber onto the rim.

There was a telly program on a while back and it was filmed at Goodyears factory, they recomended new tyre go on the rear always, this means you always have relative control of the vehicle.

Or was that the other way round??? - S*it I have... forgoton! Andy

Where on a car should a pair of replacement tyres be fitted?

In general, they should be fitted on the rear axle, irrespective of whether the car is front or rear wheel drive. This will help to keep the car more stable, particularly in wet conditions.

I know when i fit new tyres on my RWD i have to wear them in, too green and cos of the release agent IIRC. New fronts i get more understeer.

Thought they drove like that everywhere! :o)

Mind you, given the pisspoor traffic 'management' and the rutted, pothole-ridden dirt tracks they have the audacity to call roads round here, no wonder motorists get wound up.

The message from "Carl Bowman" contains these words:

Wonder how Carlisle got on with their experiment of switching off the traffic lights to improve traffic flow went.

You listen to the tyre companies. I'll listen to the wear on the car.

The end that works 'em harder gets the better ones.

End of story. If you want more, Google's got it all.

Over simplification.
