Does anyone have any mileage data on Ecopia EP100s?

I think your projection of 40-45K miles is reasonable and is consistent with my experience. I recently bought a set of Ecopia EP422s to replace the EP100s on my 2004.

 

I just can not understand how can your tyres last that long? I have done only 30k km (18.750 miles) on my stock Bridgstone Ecopia and have very little thread left, I have currently winter tyres but will probably buy new set of tyres when I change back to summer, in wet conditions they were already very slippery last year.

I don't drive that hard, I manage over 54 MPG in the summer.

 

Yes OEM tyres on Gen 3, I don't remember the exact number but they are Bridgstone Ecopia year 2009

 

There is a difference between Ecopia tires installed on G3 Prius, vs. the aftermarket Ecopia EP100 (a summer tire) and EP422 (all-season). I think the model designation on G3 is EP20 or something like that.

 

I bought 4 Ecopia EP100's when I purchased my 2004 used. I also purchased a lifetime alignment package and have it checked at least once a year. I replaced my front tires at 70k, only rotated once at 10k. I still have the rears on at 88k, they will need to be replace soon. I drive 70/30 highway/city commute to work. I am very pleased with the service life on these tires and would recommend them.

 

A tire at 35psi is not going to last as long as the same tire at 40psi or 45psi. It would be helpful to state the tp along with the mileage.

 

I am running on these same tires I have rolled about 27k mi. on them. I rotated them about ~12k mi. ago and I did not notice any significant wear either way, front or back. I inflate 42-front / 40-back. I also have not really seen any improvement in gas mileage over the previous tire (0.5 mpg average higher than before), which were Bridgestone Potenzas the dealership put on new around the 60k mi. ago when I bought the Prius used. They are a lot quieter, though. Now that I have noticed.
