anyone know how long they last?
i know their pretty good tires.

im still trying to figure azenis or so3's.
both are really heavy. Is there any other tires that are equivalent
but lighter in weight?

i need one that is okay in rain also. and not wear out super super fast.
what treadwear is good?

 

Azenis are inferior than S03 in terms of rain and longitivity of tread wear. Azenis has stiffer sidewalls which outperforms S03 in cornering on dry surfaces and you can also autox with it.

So far, with 2 events of autox, my S03 still has half penny left of tread wear.
Different manufacturers have different tread wear indication numbers. You can't use Falken's tread wear number to compare with Bridgestone's.

For street tires only = S03 (I use them on autox if it's a rain day. Holds up good! )

 

S-03 = best tire for the street and good on the track too. But quite heavy....
