I obtained most of this set of three as a second hand from another fellow driver of Mazda6 Diesel in HK. He has done approximately 4000 miles as I got them.

Had been driving around with them for about 10 months, and did some 20000 miles on them. Swapped from Bridgestone Turanza T001 (stock tires from manufacturer as brand new), and immediately noticed that the grip is better, and generally quieter. Some people complained about the soft tire wall, and my response is to pump quite a bit harder. I do 35/38 PSI (cold/warm), and notice that the behaviour of the tires would suit the car better too!

Wet grip is generally good, braking distance is good in general, while there are bad episodes that failed to stop in the right distance (more problems with brakes than the tires though). It’s less bouncy when on bad road surface when compared with the Turanzas. Given the price point of the tires (~£80 per tire in HKD equivalent), while PS4s would be something into (£200+ per tire in HKD), I would consider the SU1s a steal.

These tires come with 7mm tread. They are excellent until theyre down to 5mm. Then they become death traps. I noticed most good reviews on here are after relatively short mileage. Dont risk it.

I purchased the Next SU1 tires having come from Bridgestone Performance Tires which grip really well, but were considered noisy.

I am driving a BMW 3 Series on 18 Inch Alloys and once I swapped the Bridgestone for the Nexen Tires I immediately could feel a significant difference in comfort and a reduction in noise.

I am incredibly impressed by the Nexen Tires as I had never heard of the brand before, but once the Tire Mechanic convinced me that it was of good quality and manufactured in Korea, I decided to try.

The Nexen Tires are much more comfortable on the road, and glides over the road and uneven surfaces much better than my previous Bridgestone Potenzas. The Nexens are also much more quieter. Considering that they are also significantly cheaper than the popular brands, I will be sticking to Nexens from now on and swear by them for a good daily driver car's tires! I am not sure of the performance of them as i do not drive my car hard.

Great tire!

I bought 4 Nexen SU1 for my Mondeo Titanium X ( 2014 Reg ) after having Goodyear Efficient Grip on all 4 and then Pirelli P7 on fronts. To be honest the handling, comfort and road noise on the Nexens is as good or even better BUT, and it's a BIG BIG but for me, I was getting in excess of 50 MPG before the Nexens but am struggling to get 40 MPG on the Nexens. I have had a full geometry test on the car due to excessive wear on the Pirelli P7. Although the Nexens cost £76 opposed to £98-£110 for Goodyear/Pirelli, the MPG will ensure i don't buy Nexens in the future.

Surprisingly these tires are very good. I was doubting them before i bought them, but after the sales man convinced me, i went for them. Plus they are a great deal cheaper than the Pirrellis that i had on my car. I have only had these tires for a day, but i am impressed already. immediately after the tires were fitted on i took the car out for a drive (dry road conditions) and performance of these tires is really good. Honestly there is no difference between these tires and the Pirelli, although i feel like the Nfera SU1 handles better in wet. Later at night it rained very hard, so i took the car out again to test the tires and i could comfortably do 180km/h - 190km/h in heavy heavy rain. Quite impressive !!

After much research, and after reading many reviews, I decided to give these tires a chance. I must admit that, for the price, I am more than happy with them. They have good grip in dry conditions and I have driven on wet roads and they have performed well. I don't push the car too hard so I couldn't comment on how well they would perform under more strenuous driving.
I had Pirelli tires on previously and I haven't noticed a great deal of difference. Road noise is a little more noticeable but not so much as to make driving uncomfortable. Good tread pattern and positive handling. I cannot comment on wear as they have only been on the car for around 400 miles.
To be honest I would say that for a mid range tire, within a certain price range, they are very good.

6000 km and half of the profile is missing. ( most km is made at low speed...to work and back )
Weak in curves because, it has too soft sides. Not for sport driving in sharp bends...

it is fairly quiet and comfortable, but I will definitely change them for something better.

I carried out a lot of research for 225/40R18xl and 255/40R18xl for my Lexus F Sport. The previous tires were Continentals and I could not get on with them as well as they were at 3.5mm. Someone suggested I look outside of the box re brands and hence NEXEN. The cost for a mid range was well received at £375 including tracking. The previous reviews were pretty good and in essence they were accurate. I have only covered 1000 miles so this is very much an initial review only. Wet weather journey over 250 miles in heavy rain was an eye opener as the road holding, feeback and braking were very very good! Dry weather braking and road holding were also very good the following day and 250 miles return journey. I cannot speak for the wear as yet given the mileage covered so far. If the last 1K has been an indicative example then it bodes well. The NEXEN warranty and service support is also excellent should I have to avail myself :-), have a look at their www site for details. More to follow in 9k.

Good tire in handling and grip, but bad quality sidewall, I had them for 10k miles and it has lots of deformation and holes in the sidewall, has to change them really quick

I have them for 20.000 km on a family car and the wear is much worse that it should be for in city routes, thats the major disadvantage.

The grip was good the first 10.000 km but after that it goes bad.
