Hi, ive just taken off the Wanli tyres that the previous owner had put on and replaced with Vredeatein Quatrac all season tyres, these are non run flat tyres and have absolutely transformed the car, it is now sure footed and a lot more comfortable and have had no issues with loss of grip.

Wanli? never heard of them until now, theyre Chinese rubber.
If they were the best they'd have them on F1 cars.

Hi ya

DO NOT mix and match tires run flat /non run flat and tires manufactures you need all 4 tires the same, or it will mess up the stability control which then will affect your handling. get some good quality tires all round and get the car 4 wheel aligned.

personally i do not like pirelli tires i have always found the grip poor in damp or the wet

you may also find that what you could do in your other mini you can't in the S you may have to tweak the way you drive it

If they've got decent tread depth they can still be crap if they've been on the car for years and gone hard and cracked.

I wouldn't get too hung up on mixing and matching brands provided you have a matching pair on the same axle. But if you are swapping them all out then this isn't a problem.

I've just fitted non run flat Hankooks all round, the difference is very noticeable, much more compliant ride. Though the ones on before were old and cracked so anything new would have been an improvement.

Cheers Nige, would love a softer ride and know how I should be able to put it round corners and it just starts drifting , think I will go for non run flat vredestein quatracs

Throw the Wanlis in the bin. Cheap tyres are cheap for a reason. Autocar magazine did a comparison test of Chinese brands a few years ago. The wet grip offered fell well below that of a premium European tyre. And when do you need the grip most... Yes, in the wet.
All tyres homologated for figment to BMW/Mini have the star symbol on the outer sidewall. They're designed for the car.
As for Big Nige saying you can mix brands per axle. Don't, as you'll get an imbalance of available grip.
If you want to stay on the black stuff on a sweeping right hander in the wet, and not exit stage left into that big oak tree, then take a good hard think over your tyre choice.
I investigate fatal collisions, so I know what I'm talking about.

You may investigate fatal collisions but you obviously didn't investigate my comment correctly. I said a matching pair (i.e. brand) per axle.

Now where is that Oak Tree?

I switched my Pirelli Euphoria runflats to Khumo Ecstas last year and they have been very good in all conditions.

The new tyre labelling system will point you in the right direction for good wet weather grip (and stopping).

The Khumo's have a higher wet weather rating than many of the 'premium' european options, which is why I eventually chose them.......their not too expensive either.

Beware - the EU wet tyre rating isonly for wet braking, not wet cornering, which was the OP's concern. For example, anyone who has driven on wet roads with winter tyres will know that they have spectacularly good wet braking but mediocre wet cornering, at best.

In general it pays to avoid getting 'specification-itis" where the quality of anything can be measured by one or two parameters, as that doesn't often say whether the item works well or not. Americans tend to focus about cornering g measured on a skid pan, which is a measure of ultimate grip and tells you nothing at all about handling. Ditto those folk who buy a camera with a high megapixel count that tells you nothing about the lens in front of it.
