No point throwing away money and getting your current ones changed....
I disagree. What if the ShyteMaxxes break grip, and send you sideways into a wall or hedge, or oncoming traffic. The 'apparent' cost of wasting money on buying new tyres will long be forgotten when you have to cough up an insurance excess, and the subsequent increase in premiums.
I think you're getting a little carried away here, though they may not be the best tyre they are not dangerous either.
Then we had best agree to disagree.

If you drive like a moron you will end up in a wall or hedge regardless of tyres.
Agreed. But the big problem with the ShyteMaxes is that they brake away without ANY warning when cornering. Virtually every other decent tyre will give the driver some feedback, and therefore warning when the limits of grip are being neared.
And another big problem - when the GTI was first launched, and given to all the press hacks - it was unanimously touted as being superb in its handling, and also giving good feedback on the limit too. But when Wolfsburg started to fit the ShyteMaxxes, they really spoiled the handling.

Finally, there are many 'safe' places to drive on the limit - including race tracks and private airfields.

If you drive with any tyre thats too worn for what you are asking it to do you will end up in a wall or a hedge.
Huh - who said anything about driving on a tyre 'too worn'?
The trick is to know your limits and the cars (tyres) limits.
Agreed.

Sportmaxxes are not so bad that this limit will come out of nowhere and surprise you....
Sorry, but I strongly disagree, and my POV also seems to be supported by others here.
ETTO though.
If you want a good, cheap tyre I would strongly recommend Falken FK452. I paid £101 a corner fitted and tbh I think i could have got this cheaper by buying online.
But you can get PS2s for about £130 each - so why scrimp and save £30 - especially when tyres are so 'safety critical'?
Most people will save £60 - £120, not insignificant 
So how much is your insurance excess?

Or how much does it cost to get a kerbed Monza 2 repaired?
