I have a slow puncture on my rear drivers side tyre.
When I picked up my used 2019 A4 Avant 40TDI Quattro S-line in June, Audi approved had replaced the front Contisport 6 as they were under 3mm at just 10400 miles (soft as butter), but as the rears were just over, they left them.
With the puncture, it feels justifiable to replace the rears now (I assume a difference of 4-5mm fronts to backs isn't a bother to the Quattro system or Audi should've replaced all 4 tyres?).
So the A4 comes with 245/35 R19. Why Audi? Such an uncommon size, no-one keeps them in stock and they have to be ordered in. I can get Michelin PS4S in 255/35 R19 for 70% of the price of the 245s.
VW did this with the Polo GTI too, putting 215/40 R18s on instead of the common as muck 225/40 R18s. The Bridgestones that car came with are atrocious so swapped them out. The 215s are about 60% dearer than the 225s. I put 225/40s on the Polo all round as changing all 4 it wasn't a concern.
Such a PITA that VAG make poor sizing choices that bite the owner in the pocket come changing time.
I'm presuming VAG get these obscure sizes cheap or that slightly narrower tyre choices squeeze the car into a lower emissions bracket.
In Costco today and I could get 255/35 R19 Michelin PS4 for £128 each and £50 off a pair in a promo that ends today, making them marginally over £100 a corner.
In 245/40, it's £174 each.
Decided to wait until the Goodyear offer kicks in tomorrow and get some F1 Eagle Supersports for a slightly more reasonable £159 each plus £50 off a pair. (£119 in 255/35 R19s...Damn you Audi! ).
