These are a solid wet weather tyre with excellent wear properties over standard OEM (Bridgestone Re040) tyres. They are a little skidish during hard cornering on dry services and lack a fair amount of dry grip. I'm a little gun shy after unpredicted drift into a bend. I will opt for a more grippy tyre to enjoy more spirited driving. As a daily drive its a good value tyre though, particularly for your grandmothers car.

I bought this 1month ago and for some reason at first i put these in rear of my car (which should be 255.30.19) and amazingly it was the best tire i ve ever had in my rear axel , it was the best grip i v ever had , and then i found the michelin pss and put these in there right place in front axel , and now these are very bad in cornering and braking , use these tires just in rear of your car

best tyre I ever bought

perfect grip. Very good on wet roads

Running theses on my 2002 MINI S. These tires are perfect for spirited driving and fantastic in heavy rain. I like them so well I’m on my 8th set on this car! I get about 23-28,000 miles on a set. Ran Pirelli (run flats) Kumho, and Coopers. Sumitomo’s are by far my favorite. BTW....277,000 miles on my MINI

These tyres are good for price

they are what they are, a summer tire maybe one of the best in that matter and on wet surface they work very good but the real problem is their side grip on wet surface , you can brake and be sure that they will stop the car in rain on a straight line but if you are not experienced enough their side skiing can make a disaster, trust me many times i felt their side instability not in corners! No, they dont need corners to ski even the change in asphalt materials can make you lose control, As a mechanical engineer I ONLY recommend them if you live in a dry place.

I was recommended 245/40/17s by ian diffan and they were incompatible with the traction control as the diameter was incorrect but sumitomo did come to the party and replaced with 245/45/17s that cured the problem but proved not only to be no where near as good for grip or traction as the pirelli's they replaced but look terrible to the point of replacing them within a week to my loss

Excellent dry and wet grip, very predictable tyre. Would certainly buy again.

Reasonable grip in the dry for the price, quite and comfortable. Diabolical in the wet. Traction control cannot keep these things on the road. I'd fit these to an awd or low powered rwd but 350hp+ at the rear is shows these tires limitations very quickly.
