Tyres mpg
I wonder if its the tyres saving fuel or the wheel sizeAgrea with MJCQC re rolling resistance and weight The AP I had was more economical following a Tekna to bottom of Spain in convey by about 8 euros a tiny amount but then we cant say both cars were same weight
Some interesting views here and thanks Guys. The Continental tyres had only done 6k when removed and there was no appreciable wear on them. As stated above the overal diameter of the wheel and tyre remains unchanged (almost).The original setup was 225/45 R19 and this has changed to 215/60 R17. As such the rims reduced from 19" to 17"The tyre depth increased from 3.99 to 5.08"Overal diameter increased from 26.97" to 27.16"When the speedo reads 30 mph the actual speed will be 30.21 mph. (Give or take for normal under read for cars speedo which is around 3 mph).
