To my thinking braking and steering in the rain happens on a far more regular basis than lift of or powered oversteer!!
Doesn't this just reinforce the reasoning best tyres to the rear? Your new fronts grip well in the wet but the worn rears will let go and try and swap ends.
Who has ever had that happen?....under heavy emergency braking there is so little weight over the rear anyway. Far better to increase that slight risk rather than increase your braking distance by 20 metres (or whatever) or not be able to steer around the obstacle due to fronts worn down near the wear bands. As said each to their own.....but this gives a fairly balanced view IMO.

If you cant be bothered to read it this is the conclusion.



Cornering on a wet surface – BEST TYRES ON THE FRONT AXLE

Wet steering without ESP – BEST TYRES ON THE REAR AXLE

Wet handling with ESP – BEST TYRES ON THE REAR AXLE with large tyre difference / BEST TYRES ON THE FRONT AXLE with small tyre difference

Changing lanes on wet roads without ESP – BEST TYRES ON THE REAR AXLE

ABS dry braking – BETTER TYRES ON THE FRONT AXLE (the differences in the results were not big
Sounds like Mr. Alfa knows more about tyres than Costco, Kwik-Fit and all the major tyre manufacturers (Michelin, Continental etc!) :)

From the end of the article oponeo concludes.. (my highlights)

In our opinion
An unexpected and strong rear-end skid during braking on slippery roads and corners is a very dangerous situation to deal with, because you can quickly lose control of your car. You can also reduce the steering ability of your car, which can be improved by reducing your speed or braking. This is why car and tyre manufacturers often recommend that less worn or new tyres should always be fitted on the rear axle - regardless of whether the car is fitted with rear-wheel drive or front-wheel drive.

Aquaplaning can be felt when the wheels on the front axle of the vehicle lose contact with the surface. It cannot be felt when the rear wheels lose contact with the road surface. This is why it is dangerous to fit tyres with a smaller tread on the rear axle.

Another concern for drivers may be that they are more likely to burst a tyre that has a lower tread depth and is on the front axle. The tyres are reinforced in the tread area by strong steel belt layers. When driving into a hole or running over something at high speed, it can be enough to burst the tyre.

It is also worth remembering that you should change all your tyres when all four are heavily worn out. It's not recommended to fit two winter tyres on one axle only, due to the imbalance of the car's equilibrium. This can also lead to a loss of grip and dangerous road accidents.

Please note that under certain conditions, better tyres can be fitted on the front axle, but these are not common situations. If you don't have the time to test and analyse your tyres thoroughly, then whatever the drive system of your car, a better, safer and more versatile solution will be to fit the better tyres on the rear axle
@Will Not at said it just my view and it makes sense to me. Online you can find arguments for both POVs (see my link above).....Your car....your rules. I might be more tempted to go the other way if I was driving a high power RWD car though...not sure.

@whitenemesis I saw that...but it certainly runs contrary to the headlines I copied and pasted above from the same article....

I'll leave you to your own decisions. :) 👍

I think they (oponeo) address that in their last paragraph?
Doesn't matter what tyre's a performance Audi has on the front its still going straight on 1 of the worse cars for understeer 🤣🤣🤣 and I dont need to be a salesmane to know that
10 to 20 years ago maybe.... things have much improved in recent times..... but to be honest I'm going on recent reviews....I haven't driven a fast Audi any distance in ages.
I test driven the RS6 & RS4 before i bought the W205 C63 and tbh I didn't enjoy it ,I was also offered an RS5 as a px for the 63 which I wasn't impressed with, now the V10 R8 is a totally different story l loved it enough about Audi as for tyre's id go MPS4S any day of the week until I see feedback from the 5S when they are available in all sizes 😀
On AMGs having proper tyres in the front is mandatory , I would have thought most AMG owners are experts at controlling rear wheel spins 🤣 but front grip going suddenly feels much harder to control especially if your rears are gripping properly. The fronts should definitely not lose grip before the rears in most conditions in any case in a rwd car hopefully as the power is being applied to the rear. It so happens that before I put MP4s on the front tyres on my e63, it was on pirellis that had worn on the inside and on my favourite slopy road I gave it some juice and the nose was going everywhere but the rears had new GY eagle super sports that were gripping well. it was fun to control and I did it all week on my commute but only because I was only going around 40mph on that uphill road each time. If that happened at higher speeds I'm not so sure I'd be enjoying it that much.

On the subject of pirellis, my e93m3 has them and the rear grip is so bad that the TC light keeps going on at lower revs if I put my foot down and that car has so little torque. They are reasonably comfortable tyres but I'll change them to conti sport 7.

pilot supersports are great tyres but they're not comfortable and not great in the cold compared to most recent offerings from michellin etc
Had the Pilot 3s fitted to the rear today... they feel great at normal driving speeds.. when they are scrubbed in.. I may explore further ;)
