I bought these tires to replace some Runway Performance 926 tires that had worn badly due to tracking problems, and I have to say the difference is very noticable.
Autogrip P308 in comparison to Runway Performance 926 tires wear better, have a stiffer sidewall, lower road noise, better dry grip and wet grip by a considerable margin and are far more progressive. Also they have a very useful rim lip overlap that protects the rim well from curbing and scuffing. I am well pleased with these tires for the cost vs performance.
However, the Autogrip P308 is not an expensive tire and this shows in several areas. To start the wet highlights the drawbacks in tread and compound; it is slower to stop from speed and corners less well than more expensive brands, however as a budget brand this is understandable, and it still performs very safely.
At high speeds the tire isn't as balanced as it should be, with vibration beginning to set in as you approach an indicated 75mph, however this is mild. For this reason I wouldn't reccomend this tire for fleet car work, but for mixed driving or town work this tire is an excellent compromise.
Grip when cornering is surprisingly good, the feel is progressive and the vehicle controllable as you approach the limit. This is aided by the strong sidewalls which I am genuinely impressed with.
Rolling resistance appears to be very good considering the high dry grip levels, as my fuel economy has actually noticably improved since fitting these tires, while the Runway Performance 926 tires were awful in this regard, I'd say an approximate 5% increase in mixed driving over the last 2500 miles.
Overall I would return to the Autogrip P308 as it really is exceptionally good for the price, but I would always prefer a Hankook or Khumo to these.
