Castellated / Sawtooth rear tyres mk7 GTI

[m4t_lee]

Hey all, has anyone experienced this on a mk7 GTI at all please?

My mechanic says it's fairly common and caused by the rear bushings on the MK7 getting soft causing the rear of the car to sag, the wheels to toe out and causing the tyres to castellate.

It could just be as simple as the geometry is out and needs sorting. I bought the car last year and put a fresh set of PS5's on

Yeah, I've got this on my 7.5 GTI, which I bought it at the end of June with 26k miles. I paid for an AA inspection before buying, and the report said it sounds like a rear wheel bearing needs replacing, so I thought no bother, I'll get that replaced under the warranty. Since I've had it though I've looked at the rear tyres and the noise if definitely from sawtooth on the inside edge of the tread. My rears are Bridgestones and about 50% worn, tempted to get a wheel alignment when I need to change them.

Usually caused by wheel alignment rather than bushes unless high mileages. 4 wheel hunter system alignment sorts it.

your Bridgestones will go off before you get the other 50% worn down. Had my original factory Bridgestones on for three years and they still had 5.5mm left but they'd gone rock hard and were noisy. Replaced all 4 with new Asymmetric 6s and it's like driving a different car.

Interesting, glad it's not just me then. I'm going for a free hunter check next week. My mechanic who's next level brilliant says if it's the bushings then it'll just go again but worth a check just in case it's just out.
Was thinking of popping the fronts on the rear, replacing the rears with new on the front and if it happens again at least it'll take a while and the old fronts will almost be ready to throw by then

Thanks, hopefully that's the case, will see how out it is next week, they said they can check over the bushings too

Both my mk7's that I had from new did it.

Replace the tyres, job done.

Good idea to swap rears with fronts when you eat up your fronts (fronts last about 14k, rears get sawtooth before they are worn out). So put new tyres on the rear, old rears on the front.

^ What he said. Stick them on the front and wear them out.

Mine also castellated on the rears, replaced all 4 rather than swap rear to front as the rear side walls were beginning to show early signs of age cracking (just over 4 years old). Replaced the Potenza’s with PS5’s - big improvement in ride and noise.

My 2019 GTI pp also had this on the rears,sounded like the rear wheel bearings needed replacing. was on the original Bridgestone tyres at 25000 miles. I replaced all four tyres for PS4s and it now feels like a completly different car
