Hi All
Removed my 21" Turbo 11 Wheels which were fitted with Continental Crosscontact UHP 295/35/R21 tyres and replaced with 18" Cayenne wheels fitted with Dunlop Winter Sport 3D 255/55/R18 tyres on Monday past there. i have noticed a significant increase in MPG. With the 21" wheels i was getting 29/33 mpg on local runs, now with the 18" wheels fitted i am getting 37/40 mpg on local runs. The car is alot softer and seems to free wheel /coast alot more.
Regards Hugh
