Tires RIKEN or LANDSAIL

I’ve been using them for a few years now and we’ve currently got them on a Mazda 6 and a Saab 9-3 and they’re fine. Mine are rated B in the wet and I’ve had zero problems with them.

Rikens are fine. They're quite a soft tyre, probably because like you said Michelin make them butbthat does meant the grip is decent.

Speaking of cheap tires, I recently switched my tired old 41k mile Sumitomo ZIII with these $43 in 225/45 17 Riken raptor ZR and quite surprised how well they are. They grip as good as my ZIII did, way quieter and rain performance was fantastic. I was hesitant at first until I read reviews on tirerack phrasing these are great tires and they are definitely good. I also learned Riken is part of the Michelin tires company so its probably of decent build quality.

They have an aggressive tread pattern and I have driven them for the last 7 months in a variety of conditions from downpouring rain to hot, humid sun and they have not let me down yet. I push them hard on a cloverleaf on-ramps. They grip well and don't even chirp.

Have these on the 944 and they are surprisingly good. Not pirelli p7 good, but good and they hold up. Honestly I have no issues with them. (Riken Raptor ZR summers)

I got my car from a dealership with Landsail tires on it. Complete garbage

Landsail tires are cheap Chinese tires... I'd replace them as soon as is financially reasonable and possible, as I wouldn't trust my life to Chinese tires.

My R32 came with 4 matching 'new' tyres. They were made by 'Landsail' which apparently is a premium chinese brand... yeah ok... but anyway took it for first MOT a few weeks later and they phoned me up soon after saying I was lucky to still be on the road. The inner walls of the two rear tyres had almost completely perished, held on by threads almost.
