Vekke · 07-10-2016, 07:20 AM

6500 km driven with 155/70R19 bridgestone ecopias:
FR 5.2mm
FL 5.4mm
RR 4.4mm
RL 5.2mm
Once changed positions front to back. Wheel angels were off bigtime so now they dont wear off so fast.

When these were they had 6mm in the main groove and now 5.2-5.4mm there is something wrong in that one 4.4mm tire why it wears faster and need to find it. Also notice that my car weigths at the moment in driving condition with driver 1500-1600kg so its much more than at the I3 they are meant to be used.

Better Testing will come are they better than other "eco" tires and sizes. I think they are better than tires I had last summer, but I have 4 sets of wheels to try this summer and a 4 hp test ecu program to do the tests so I should be able to see differences that are under 0.5% in fuel consumption.
