Michelin Primacy MXM4-Mileage when replaced?
 

For those who had Michelin Primacy MXM4s as original tires on their car and who have purchased new tires--at what mileage did your replace the MXM4's?

Around 40k, but still had another 10k left on the tread until 2/32”.

47,500, started to see sidewall failure (splitting) on the inner sides. Tread would have lasted a bit longer however. Aged at replacement was 5.5 years. I have the same tires on my other Lexus, with about 25K miles, and at 5 years of use, I am starting to see some splitting issues in the tread grooves.
So, tread depth is only part of the equation, age is an equal consideration.

50.2k

The outer edges were especially worn out (no groves left) when replaced, middle was at the wear bars.

When i got my 2016 ES300h it had 37k on it two tires where brand new and two where the original Micheline had 3/32nds tread left on the original Micheline tires at 37k this was also a Florida vehicle hotter roads tires wear down .

so also how about when posting tires miles when replacing what climate you where in also when?

2013 ES300h tires replaced at 45,000 miles. They could have gone to 50,000 miles but I did not want to take any chances.
