What drivers say about their 225/40 R20 tyres
The most recent owner reviews fitted in this size, in their own words.
EVERY SINGLE SIDEWALL HAD CRACKS which prompted me to replace them immediately. Dry grip was OK but wet grip was non existent with constant wheel spin under light acceleration.
Braking was a different story. It would cause the steering to snatch violently in the dry (I've had replacement discs, pads and calipers)
I've noticed that some others have mentioned that they thought their wheel bearings were failing - I had exactly the same issue and since replacing the tyres, this has completely gone away.
If you value your life or anyone else's in your car, avoid these tyres at all costs.
The only reason I have given these tyres a 1 for wear rating is due to the sidewalls. There was still around 5mm of tread left on each Tyre at replacement.
Only changing tyres early as down to 2.5mm and it's the rainy winter season.
