I've always thought it daft to have a car that will destroy its tyres too quickly - I'm not rich/stupid enough to be prepared to trash a set in short order, but it does seem as though there's a growing subset of cars whose handling/performance is very much led by their tyres, and seems well beyond that I'd consider acceptable. The latest Focus RS seems to be a tyre-eater according to the magazines, and I noticed that Autocar's Giulia Quadrifoglio is on its 2nd set in pretty short order.
evo is running one too, and this month's entry in Fast Fleet is interesting. In filming they managed to shred the tyres in four laps. These were also laps which weren't at the ragged edge, and cooling down laps were used. Oh, and they were the fronts...
Seems that the car's turn-in is bought at the considerable expense of longevity. The treadwear rating is (what they describe as 'unbelievably') low, at 60, meaning a theoretical life of less than a fifth of the likes of Michelin PS or Goodyear Eagles, which are both in the 300 range.
That's silly, to my mind. |

Agreed. The front tyres on the Benz generally last around 35,000miles, with rears about 25,000. I assume that is partly thanks to the Airmatic suspension keeping everything well under control.
I remember my dad got 45,000 miles of motorway driving out of the tyres on his Peugeot 405.

I agree, doesn’t make sense to me at all. The P Zeros on the Boxster are bad enough, 10-12k max for the rears, but at least they last a year thanks to them only being on for 9 months.

It is interesting and I'm sure that an average driver on the road (where 99.9% of these will spend their whole life) wouldn't notice if the treads were a bit harder for added longevity.
I keep meaning to check the Pirellis on the rear of the Nissan but forget!

My wife's old A5 Quattro used to eat its way through a whole set in about 12,000 miles

The X4 will undoubtedly chew through outer front shoulders in fairly short order.

My tyres are nearing change point but that's 25,000 miles which I think is great. Front outer shoulder is certainly more worn than the rest of the tyre.

I think all the BMs I've had have done that to the front tyres.

The Civic has had a new set of both summer and winter tyres, the originals lasting an accumulated 180 000km, so 55 000 miles each.

I have had un-driven tyres which lasted that long but never driven wheels.

I drive conservatively but I do not drive like a saint. Maybe it is the lack of low-down torque that helps. I very rarely break traction or provoke a skid. |

The summer rears on the BMW lasted 33,500 miles and the fronts 55,420, which I think is pretty good. The winters haven’t lasted anywhere near as long, they obviously need to be replaced earlier, but the rears have just been changed after 16,000 miles.
The Boxster wear is at the other end of the scale, 11,000 miles for the rear and 20,500 for the fronts. The winters have done about 7,000 miles, but have barely worn at all, no more than 1mm.

That's not good, it's incredible!

Unfortunately I spend the vast majority of my time on dual carriageways and motorways.... Maybe not having them on in the winter helps as well? |

I expect they would wear slower in cold weather?

I was thinking colder temperatures = less grip = more wheelspin = more wear? I could easily be completely wrong.

I was thinking of the fronts rather than the back.
Have you looked at the treadwear number?
I'm thinking it might be in the 000s!

All that torque and still lasting that well is pretty damn impressive! |

I don’t know what the scale is, but it looks like the tyrewear indicator is about as useful and manufacturers fuel consumption figures. BMW summer tyres  Porsche summer tyres as a comparison, which last about 25% as long.  |

I got rid of my Clio at around 28,000 miles and had just put on its fourth set of front tyres!

I expect the soft modern tyres are a factor, but I suspect the driving is the main one! If I was half my age and not having to pay the bills for it, I doubt my rear tyres would last much longer. But in fact in 50k miles I have changed one pair of summer rears (about to do the fronts, and a bit weirdly they inside edges are bald) and the winter tyres still have 6mm all round. I only use the winters for about 5-6k miles a year so it looks like my summer tyres last about 20k for the rears and 30k for the fronts.
I can't believe the winter tyre wear as I quite frequently slide the rear round a bit to help go round corners at low speed (on wet surfaces). I think it just shows you can hoon a bit and your brakes and tyres still last well - but hoon all the bloody time like a journo and they do not!
I also think there is something in the "summer tyres wear faster in the winter" argument, it is supposed to be because summer rubber gets hard and wears faster in cold conditions. I definitely see my summer tyres lasting for a lot more miles on all cars since doing the winter/summer thing.

The Calibra 16v I had went through front tyres at an alarming rate. 8000 miles off the first two sets. Which in line with Clio's, RS Fords etc, probably confirms that FWD and any power = crap tyre wear.
On the other end of the scale, our Shogun did over 60,000 miles on a set of all terrain tyres.
I expected the XFR to wear tyres quicker then it actually does, but as Alf says, not hooning it everywhere and sensible braking (probably as important for tyre wear) is one financial benefit of older age and it being your own car.

The R1 has tyres that have a different compound round the centre to the edges, so it sticks when you need it to and wears better when you're in a straight line. On the basis I'm old and sensible and very rarely (almost never) put all 172 horses through the back wheel and commute on it my tyres last an inordinate length of time for a superbike: I'm more aggressive on the front with turn in.
