I have not used Advan dB. but I am using Es32, They provide good road grip, Comfort is a lot better that the OEM Euro Star. I am using 195/65. I have noticed a drop in Fuel economy of around 1km/l based on car computer calculation.
Now car jumps to higher rpm during initial acceleration. but once it goes to cruising speed rpm becomes normal (same as they were with 175/65 Euro Stars)
Though small bumps like crossing the cat eyes have become very smooth but once I hit a pot hole. I feel the thud. May be because the tyres are heavier than OEM so shock absorbers does not dampen their downwards movement enough. Car is just 40K driven so I don't suspect that Shock absorbers are gone bad.it could only be due to the weight of larger tyres.
These tyres have given another 0.5 inch clearance. Now with 2 persons the cars does not hit the bumps it used to it with OEM tyres. Yet to check the clearance with full load
