In hot weather, screeching is very noticable even at moderate turns. ABS is noticabely more often triggered during normal traffic light stops, compared to the winter Hankook set. I think even some premium winter tires screech less when driven in hot summer weather. They also seem loud at highway speed, but I don't have a reference summer tire to compare.
Otherwise, they have a solid and "plasticky" feel to them, which gives you confidence over poor quality and unpaved roads. Gives you impression that you are driving on bigger tires. The wear seems very decent, too.
Overall, I'm not very satisfied for a tire at this (low-medium) price renge.

What drivers say about their 175/55 R15 tires
The most recent owner reviews fitted in this size, in their own words.
Once you are outside the realms of budget tires in the UK I'm essentially down to a choice of Sincera 110 ecoruns or a mixture of Continental ecocontact.
The Continentals carry a hefty premium over the Falkens - even with a 15% discount from my supplier I'm still paying £65 more for 4 tires than I would should I choose the none discounted Falkens. ( £345 v £410).
Not only that but I'd be having a mixture of ecocontact 3 and 6 which seemed odd that I would be paying a hefty premium for a tire that was essentially 3 generations old - research on this site showed me the ecocontact 3 was initially released in 2003!
But, more expensive equals better, right?
It would seem not.
The reviews on this website for the Continentals appear to be less than glowing, certainly compared to the ecoruns which I already have on the car.
I've been running the sinceras for a couple of years (since I bought the car)and about 15k miles. As it's a Smart car there is virtually no tread wear as the car is so light but the tires are starting to perish as they date back to 2015. Overall, looking at the MOT history and the tire dates I would guess they've done no more than 20k miles.
Ordinarily I would have replaced them earlier but as the car rarely goes above 20 mph in London I haven't really had to worry about high speed blowouts. However, I had to do a longer trip on the motorway last week where I made a promise to the tire gods that if I didn't die in a fireball I would replace them this week.
In the time I have had the car with the Sinceras I can say I've been impressed.
I run an slk 55 as a weekend / summer car and have Michelins on that.
I would imagine that people want different things from different tires and different cars. I don't expect the Sinceras to offer up the same level of grip as the Michelins but on the Smart my priorities are different - my prioritied are excellent wet weather grip - I don't want to be acquaplaning in a car with such a short wheelbase and noise and comfort rate high too.
In this respect the Sinceras score highly - I will caveat that with the fact that I am in the unusual situation whereby the tires have plenty of tread left but are no doubt a lot more brittle after being on for 10 years and exposed to UV light all that time with the concomitant degradation.
I would certainly expect brand new Sinceras to be even better.
In short, they are an excellent tire for your regular family type car where wet weather performance, noise and ride comfort are more important than outright on the limits grip - and they are certainly better than some tires that are more expensive
After fitting the Falkens, I was immediately impressed with their low noise, comfort and dry grip levels. To be honest, I wasn't looking forward to their wet performance, however, they were way better than expected and I've grown to be confident in their abilities and they have tamed the Smart's tendency to understeer. It's too early to rate their wear, but as the Smart is so light, it tends not to be an such an issue. Massive improvement over the dreadful budget tires it came with. Overall, I'm really impressed, especially as all four tires were £280 fitted.
As we live in Switzerland (ski region) i was looking for a set of good 4 season tires.
As the Kuhmo Winter Tires on the Smart were completly done. (2mm left)
A cousin of my drove from Holland to Norway in wintertime with his Saab 9-5 on The Vredestein Quatrac 5.
He is (was) a really wintertire fan in winterconditionsˋ as he was going every single year to Norway he was my perfect real experience person. He was so positive about these tires in Norway that i decided to by 4 of them for the realwheeldrive Smart Cabrio.
Of my personal experience i can say the following:
Dry: handling is okey; brake and corners are standard
Wet: very good felt really safe with heavy heavy rain
Snow: as long as you use your brain this tire is as food as a full winter tire, good traction and breaking is even better.
Comfort: i was so surprised how quite this tire really is, it felt almost as i was driving a different (newer) car.
Buy again ? absolutely!! The dutchies (Vredestein) are doing really well the last few years;
But only buy this tire if you have a normal car with not to much power. If you have a lot of power and drive over snow covered roads I would go for the Vredestein Wintrac Pro,
