The noise got even worse with wear.
After 5000 deafening miles I bit the bullet and replaced them with Devanti tires. Results is bliss I can hear my engine again.
Unless you have a wheel barrow I would advise not to fit sunny tires although they may be good for children’s swings.

Father-in-law is a mechanic and persuaded me to buy these as he had used them before and, I didn't rate the Michelin's i had on previously (absolutely shocking in the wet, but brilliant in the dry).
Having just had a baby i wanted something safe but wouldn't cost the best part of £1000 to put on all 4 corners, so expressed interest in mid-ranges i.e Nexen/ Barum etc. Having had the Sunny SN3970 just fitted i thought i would "test" them out in a rather spirited drive... By god do they grip! They have a slightly softer sidewall than most premium tires but they cost up to 4x as much as these
Most of my journeys consist of 3/4 motorway 1/4 road use. In the wet they are grippy but can let go if jumping on the accelerator too quickly, but they are no worse than Michelin Pilot Sport's. In the dry they are on par with Continental's. The road noise is nothing compared to Michelin Cross Climates, they are pretty quiet to say how cheap they are.
Plenty of tread left on still, would estimate around 25,000 in total miles but could be more with how they're wearing. Sometime it makes you wonder what the difference really is between £70 and £200...
I have put down the scores as they are now, some of the figure may get better over time and others may get worse, but would definitely consider buying these again.

I have discovered that tires now have a decibel rating as well as fuel economy and braking efficiency. Just remember though that 3 decibels is the difference between virtually intolerable and fairly quiet.
