re wheel diameters etc ..thanks for the formula the one I quoted was the old radius, so 2 of them = circumference, yes I skipped the squared bit...thanks for that...now back to the thumping...
If I do adjust tyre pressures then as I get the pressures/diameters as close to fr=back...then the thumping ..'planetaries etc' engaging should be less..?? it follows
...however tonite I have already got psi @ 40 fronts and 35 psi rears ..[tyre diameters measured as above] still thumpin'..I know futher back in the thread that some of the cars are upto 8psi apart [same tyres f to b]...so thinking whilst writing if my tyres are taller/longer on the back then they will need lesser again than OEM specs for the rears so as to compensate for shorter rolling diam on front because of the weight of the motor..?? OEM ~ 10% more air in fronts....low profile vs lower air pressure, thats not usually recommended ???
