hiya - wonder what is the significance of this 5% rule? How does it affect the abs/tcs and perhaps more importantly/interestingly why would it affect these systems if >5%?
cheers

If the ratio is greater than the 5% then this is outside of the allowed tolerance, ie the ECU will think that one set of wheels is spinning / skidding and cause the TCS to cut power.
but the differenz of the circumference of
205-50-15 zu 225-50-16 ,is 7,75%
and the differenz of the circumference of
215/40 ZR 17 und 255/40 ZR 17 is 5,3 %
:think:
Had to put the OEM S2000 rears on the NSX today, can't get hold of the RE050BZ's that I used so now on those (RE050MZ).
I've been using Bridgestone Potenzas for several years. They stick well and seem to last a reasonable time: I've just replaced the two front ones after approx 30k. Been using the same garage for many years - he charged me £200 for the pair including balancing and fitting. Last time I bought a pair of rears (lasting around 18k), they cost £215.
