Tire Thread Separation

sad Tire Thread Separation
Driving down the N3 and all of a sudden the car feels bouncy around 130kph. If I go faster then it goes away but below 120kph the car felt "off"

My mind went straight to balancing, Pull in to Super Quick Harrismith to do balancing. Guys take off the back tires first and nothing is wrong then the front tires and they call me in to have a look. They can't do balancing because the tire surface is uneven and I have been a victim of tire separation. Tires have less than 5000 kms on them dunno anymore

So one of the man there suggests I get two new tires, Run flats because apparently there has never been an issue of separating since they are heavily reinforced.

Questions:

Can I run two run flats (front) and two normal (rear) at the same time? atleast for the holidays until I get back to Joburg. Because I don't have a place to put the rear tires if I change them all.

How true is it that there has never been separation on run flats?

I have never heard of an AUDI with run flats, is there a specific reason they shy away from them?

I dipped into the holiday budget deeply and got two Continental ContiSportContact 2 SSR Run Flat 225/50r17 W at R3300 each. My drinking budget has been officially cut this this December. BlueCry

Made it safely to Hibberdene Tiptoe

RE: Tire Thread Separation
Dammit.. You must take them back to where you got them. or if the same dealer has a branch where ever you are going, if they new then they should replace.
They should not delaminate in My opinion, fight it.
But if need be you can run non Rf on the back but not one Left / one Right

I tried to swap them, called the company I bought from which I am not mentioning by name at the moment and they said they want to see them first before they agree to anything. The branches straight up refused to even look at them even though I have receipt

You can contact Dunlop and take the tyres to them, they up in jet park. I had similar issues with their tyres, they did some tests and replaced the tyres no charge. Can't remember the exact details or contact info as this was a few years ago.. Thumbs

Thanks for the info, the guys had said they don't do exchanges but they send them to Dunlop I thought it was out of the country. Will look for their details

RE: Tire Thread Separation
Thumbs good luck man - and as soon as you are sorted out - then name and shame those companies - especially the dealers down at the coast (where you went) so we can all boycott them.

Tire Thread Separation
Correct they are in Jet Park.
Had issues with some SP sport 7000s in the day and they eventually replaced them

RE: Tire Thread Separation
as a previous Tyre shop owner

1) go to the tyre dealer from which you bought the Dun"FLOPS"...WITH THE PURCHASE RECEIPT NB !!!
2) They will engage directly with the distributor
3) Dunlop will send out an assessor to the dealer, and make his "verdict"
4) If the Tyre manufacturer is at fault, they will replace the tyres - (minus) the amount of thread already used

5) Dunlops are known for their soft sidewalls, developing bulges with only lite pot hole impacts
6) Run flats are only stronger on the sidewalls, but not on the actually running surface, thus they remain more rigid and upright even when the internal air pressure is low.
7) You can easily run different tyres between front and back, except the front is way more sensitive, and needs two identical tyres (brand/wear rate/etc) on the front left and right.....between back and front is not an issue

RE: Tire Thread Separation
Good luck getting it sorted. May as well buy budget tyres instead of crap Dunlop and Continental

Doesn't matter whether it is runflat or not, a well made tyre should never do that

RE: Tire Thread Separation
Update...

Went to the dealer, They were very cool and understanding. Asked me to leave the tires so they can do their tests. Called me a few days they were going to refund me.

While at the shop I saw they were running a special on some type of Nexen branded tires. Called my buddy who has some experience with these things and he vouched for the tires. Said he is currently using them on his MK7 GTi and he has never had a days problem.

After negotiating for a bit I managed to get 4 brand new NEXEN (Fera something) 225/45R17 for the price of 2 Dunlops + R400. Going to slap them on to mom's car.

The irony is that Dunlop's top pro level tennis ball is called the Grand Prix, which is exceptionally good... go figure.
