Sunny SN3970 Reviews

Given 74% (breakdown) while driving a Toyota supra turbo (255-35-18-W)
Driving on a combination of roads for 6,000 spirited miles
These were fitted new on the rear of a set of alloys i bought for my mk3 toyota supra. I was going to replace them before fitting to the car as its highly modified, with 365bhp and 420lb/ft of torque, but decided to give them a try. They performed very well with lots of grip in the dry, only a fool would try hard in the wet with 365hp i dont care what tyres were fitted. With that much torque it dosnt take much to make the rear step out of line, but i had to use quite a bit of right foot to make them break traction, i was impressed. I also maxed the car at 175mph ( private road of course ) without a hint of vibration. Noise was not a problem because the car is so loud anyway. When i priced them i couldnt believe how cheap they were, so paying three times as much for premium tyres proves to me your paying a lot for the name when budget tyres like these will perform at 80% of the premium ones. I wouldnt say all budget tyres are as good as these, but in this case the people who rubbish these dont know what there talking about, or are brand snobs. If your on a budget, Go and buy them, you wont be disappointed.

I had some sunny 18" on the back wheels when I bought the car. Had to mot the car 2 months later. Mot tester found that the inner sidewalls were TORN/SHREDDED on both wheels ALL THE WAY ROUND. They still had 7mm of tread left. I feel like I've had a lucky escape. I will not recommend these tyres or buy them again.

Driving on a combination of roads for 3,000 average miles
BY FAR THE WORST TYRES I HAVE EVER HAD FITTED ON A CAR IN OVER 22yrs OF DRIVING!!! These should never be allowed on cars for normal road use. The road noise is deafening! Total waste of money, stay away from them and NEVER fit them to your car!

Given 54% (breakdown) while driving a Ford Focus 2.0 S TDCi (225-45-17-)
Driving on a combination of roads for 12,000 average miles
Bought two of these for my Focus. Had to move them from front to rear as road noise was loud, very loud. Still noisy on rear but not as bad as before. They handle fine in the dry, not so well in the wet. If you drive normally in the wet they are fine, but if you are a "spirited" driver or like quiet tyres, I would avoid.

Given 14% (breakdown) while driving a BMW 330d M Sport (225-45-17-)
Driving on a combination of roads for 3,000 average miles
Worst tyres I have ever bought, Have a BMW 330D M sport and the tyre walls on these sunnys are very weak, once they get warm, go round a corner and the alloy ends up scraping the road. apprantly wet road grip is 'B'. I really don't think so. Going back to my Bridgstones, thought I would give this a try and never again. If you want to crash your car, feel free to buy these tyres.

Sunny SN 3970 looks good BUT in wet........bad grip! Also the life of the tyre is poor. In dry conditions and easy going drivestyle it's a good tyre. Cheap price.

Driving on a combination of roads for 2,000 average miles
These were fitted to the car when I bought it. Never EVER get a 'Sunny' tyre. These are lethal. I've swapped them for something that doesn't to try kill me and my family every time there's a hint of rain.

Diabolical. Rubber cracked between the treads after covering 11k in 10 months.

They've become so noisy I had my mechanic check for wheel bearing failure.

Given 38% (breakdown) while driving a BMW 328ci (255-35-18-W)
Driving on a combination of roads for 200 spirited miles
i was looking for a tyre to give me very poor wet road grip(fitted only to rear) for to have some cheap fun with. i read the reviews this tyre and thought "they sound shit, i'll try them". i expected them to be pants and they are. driving normally and legally they aren't a problem what so ever. totally fine for the normal average driver. i fitted them to the rear of my bmw hoping for some fun as i normally have michelin super sports on which are amazing. taking corners 70mph+ these tyres wobble and make it feel like your driving on a oil slick, not a nice feel and above 130mph they are rather scary. In the dry when you want them to loose grip they are unpredictable, road noise isn't a issue for me but they were 'droney' (if thats a word) when above 80mph. they do however smoke very well. on the whole these are cheap tyres. if you pay peanuts thats what you get. if you want something and expect them to be great then get a proper tyre
