When I purchased my Lexus GS450H it came with rear only Riken UHPs and in the dry with roughly 4mm remaining tread very grippy hard to destabilise the car without turning off TCS.
Performed well in wet conditions with essential tread levels BUT, be careful on wet conditions and especially when at legal limit tread levels the car can destabilise without too much effort. Otherwise quite solid.

I got around 6000 miles from around 4mm when I got the car so 12000 miles estimated when new.

The tyres have a very soft sidewall, even with my low 40 profile tyre, this meant that they are comfterable and pretty good in the dry and wet. I had only had budgets or random tyres on my car before these and so when I went on a country road drive the front end felt much better (well duuhh). For the money these have decent performance but there is a major downside to these tyres... If you hit a pothole these tyres will just go, I went through both of my fronts in about 2 months doing a lot of town driving. For this reason I dont' recommend these tyres if you live in an area with bad road (ie the entire of the UK)

Excellent tyre made by Michelin price is excellent I put these on my Audi Coupe S2 tyres lasted well excellent grip wet or dry a little noisy but still ok the car is 230 bop 4x4 comfort is good although sport suspension well recommend tyre definitely but again

Purchased these tyres 2 months ago as replacement for hankook Ventus. I’ve tried my best to push them to let go in wet and dry conditions and have never lost grip enough to feel in any way out of complete control. Sport mode with driver aids disabled can barely elicit wheelspin before the grip asserts itself and launches the car very satisfactorily. Quiet comfortable ride. Best value tyres I’ve had in years £250 fully fitted on four corners with nitrogen inflation. Will definitely be buying again in future. Premium tyre performance at budget tyre price. Get some on your motor and rag them if you can or dare to. Because despite my best efforts I cannot find any real fault. Can’t speak for long term wear but they still look off the rack pristine after 1000+ miles.

Brought these for me rear wheels and I really think they are brilliant. I have now done 9k miles and still have about 4.5mm tread. I have driven on dry and torrential weather and have never spun, this is a really underrated tyre and I will be buying again.

That's it F/P

Tyre is great in wet or dry and comfortable BUT they have a very weak side wall. I have replaced 2 inside 1000 miles due to side wall damage hitting a pothole and now a 3rd has a bulge after 600 miles. I will not buy them again for British roads

Riken UHP-on my heavy Bmw E38 this tyres performs very well,good grip wet and dry.I'm done it one trip from Bristol to London in a heavy rain,BRILLIANT!I've been very confident with this tyres,realy recommended.Cheap,good performance,good handling,low noise

Bought these tyres at £75 each fitted to replace Pirelli P Zero tyres. In the dry they are about the same as the Pirellis and in the wet I have found them to be slightly better. However, these tyres seem quite hard which takes away some of the road feedback and comfort, although still not far off the Pirellis. I haven't had them for long enough to test wear or long term degradation. Initial impressions are very good and they are overall close to premium tyres in terms of performance but at a much cheaper price.

The worst tyres I have been used in my life. I have tried this brand after my old Continental tyres. Pricing of this tyres were very close to Petlas, Kumho and Falken but the vehicle doesn't stop while braking, even at low speeds. I made a big mistake to choose this new brand. Also handling is so weak too. I have to lower my speed more down as usual before cornering. Noise level is same as my old tyres. For safety on road, be aware to use this brand. Lastly, I will never buy it again.

Fine for a daily town car, used on motorway a handful of times over the past 3000 miles and they have been fine. Wet is ok, not amazing but a cheap tyre so to be expected. Will buy again though as they are half the price of Avon's and seemed just as good.

Tyres are definitely a cheap end of the market, on the wet there is no way to tell when they will give up. Unpredictable in the wet. In the dry they are ok, but again they give up very quickly and suddenly. For the price difference of 20£ per tyre between them and reasonable brand I don't recommend these. Mine were made in Serbia 03/2019.
