Vague steering after replacing tyres

[reeksi]

Had my MOT the other day and needed to replace the rear tyres. I went for some mid range tyres that were about £120 each (cant remember what they were called right now) but they are run flats.

Im fully aware of what tramlining feels like and this is not that.

When driving in a straight line over 50/60mph, I feel like im having to make minor corrections which i didnt have to do before.

at about 65mph, I gave the steering a gentle wiggle and the traction control went mad and felt like the car would have spun out had it not been switched on.

I've checked the tyre pressures and they were 32/33 psi which is pretty much spot on. I can see the balanced them, because there are shiny new weights stuck to the alloy.

- Is this just the run in period and they tyres are a bit greasy from the mold release?
- Is it that I've bough crap tyres and I need to live with this?
- Is it something else?

Thanks for everyone's help in advance.

Most likely the release compound on the tyres..I was shocked how bad my car was with continental winter tyres for around 25 miles...then it all came good...same issues, sliding around, traction light etc..

Thanks, Ive never had this before, but its probably because I've usually fitted part worn premium tyres that wouldnt have any release compound on!

Just feels so vague and disconnected from the road unlike before the change

did yours feel vague at higher speeds, like you were making minor corrections to the steering constantly?

Are the new tyres a different brand to the existing fronts?
I’ve had this before on a different car, some brands are very sensitive to being mixed :?

Yes, they are different brands, Michelin on the front, then budget friendly brand (will check later) on the back.

I'm assuming your fronts are non run-flats. Mixing is not a good idea and would suggest that is the root of your problem.

They use silicone on the molds which is indeed very slippy. It's caught a few people out especially bikers.....

Turn the TC off, get the revs up and scrub those bad boys in Fast n Furious style!

Im happy to do this in a quiet car park this evening, do you think this will help?

Get the wheel balance checked again too just in case it's not right.

What 'mid range' tyres did you fit and how many miles had you covered while still experiencing a problem?
Must admit, as I read the op the first thought that went through my mind was... Chinese tyres.

US, China, India, Indonesia and Thailand made apparently.

I wouldn’t personally but then I have no experience of them but even so, on a small-ish fairly lively roadster I’d want tried and tested stuff that come well recommend.

jesus at 120 quid a corner you could have done a lot better

Driving home just now, i went round a bend at 35mph (its a 40 limit and you could take it at 60!), and the traction control started flashing. even at low speed if i wobble the steering wheel, it just feels not planted like it did before.

Im going to have to get to a garage, I will update you all soon! hopefully i can find one local as the one i got my tyres changed at was a friends dads which is quite far away!

I know! it was going to be an MOT fail if i didnt change them, having just bought a house and planning on getting a new car in the new year, I made a bad choice :-(
