SINCERA SN110

I have had my 4 year service and they are telling me all 4 tyres are cracked on the outside rim. Will need replacing by next service. I have done 8500 miles on them. W I’ll not buy again as this has never happened before.

i have replaced bridgestone ep150 and conti ts870 (both in original size - 185/55r16 for suzuki swift 2024 1.2 hybrid ) with sn110s. Size of falkens is 175/65r15. Road noise is terrible with bridgestone, a tad better with conti but still very apparent (turkish rough asphalt, japanese b class hb car and winter tyres or eco summer bridgestones are not good matches). There is almost no road noise now. Funny thing is that sn110 looks like thin bike tyre with higher side walls compared to original ones but i feel almost no difference in handling. I think that there is a slight trade-off for comfort, which is consumption. I was expecting a little decrease in my mpg but since it is same.. Well i can tolarate against loud trips. So far so good, i hope level of quiteness goes on like this as long as possible.

The dry grip was phenomenal I was driving average before this tires but after this tires was fitted i become a spirited driver and I was sure where the silver line as for the control of the tire was and if you pushed it little further or the road was bad even if slipped with the steering wheel you could control it. The wet grip was good nothing wrong to say about that. It was fitted August 2021 and replace the two of them that was in the front in the April 2025 because has lost some little rubber in some places and was near the end of its tread but again I was driving spirited (The tires had been rotating this years and was been replacing with winter tires for 4-5 months each year. The other two will be change maybe by the end of 2025 or until the spring 2025). Maybe would not get you so many kilometers that a Michelin or a Goodyear will but I don't care I prefer to be able to perform an elk test with higher speed if needed. I had Michelin Energy Saver but then I was driving average and had the OEM suspension at that time. Now has Monroe original.

First mounted on the rear 30,000 km ago, then now on all 4 wheels for about 15,000 km. It is difficult to find quality tires that are safe in my size.
The price/quality ratio is quite good, but the wear is a little too fast if you drive dynamically. After 15,000 km they are about 75% worn. You can't have everything.
On dry ground they are difficult to fault, on wet ground you feel the limit arrive more quickly, but it is progressive. The rear axle is simply unbreakable regardless of the road conditions and the driving style adopted.
The front axle was mounted in "Feu Vert Efficiency", the road holding of the Falken is generally a little better in the wet, but really superior in the dry.
When they are completely worn out, I definitely plan to get the same ones again.

Like others on here I have a smart fortwo 450 which means you are somewhat limited in choice when it comes to replacement.
Once you are outside the realms of budget tyres 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 tyres 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 tyre 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 tyres are starting to perish as they date back to 2015. Overall, looking at the MOT history and the tyre 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 tyre 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 tyres 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 tyres 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 tyre 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 tyres that are more expensive
