just like the name suggest, different thread, part of Michelin naming system, and aftermarket PS4s with old sidewall dont have that mark IIRCWhat does this DT1 mean in effect?
I hit a bad pothole last week and front left tyre sadly split along sidewall (rim is fine). Changed to a full size spare provided by a friend. (PLEASE get a space saver for your car, guys. I was stranded in the middle of nowhere for 6hrs). Anyway, on my way back I get a nail on the rear left tyre lol (what are the odds!!) and had to drive on that flat it few km on highway so that tyre is not safe to be reused IMO as i see the ring of death. Hoping rim is also ok, it looks ok and spun ok on a wheel balancer at a shop i went to.
I've ordered 2 new PS4S in the same oem wheel size and should arrive next week. I know they won't be the same DT1 OEM spec.
Could you shed light on the differences between the OEM DT1 spec vs off the shelf PS4S?
I've heard DT1 (different tread) has less tread width, or have better rim protection, or worse compound for grip to save cost, or better carcass to help tyre steer and accelerate simultaneously but these are all whispers and nothing confirmed officially or by tests.
Thanks!
Not confirming any things, but according to initial press release by Honda JP, the OEM PS4s is bespoke and developed to maximize grip for FWD , so it's supposed to differ from other DT1 or DT tires provided by other manufacturers like BMW(either *star marked or not).
From what I have heard, many owners who tracked FL5 suggest DT1 PS4s has a stiff sidewall and superior traction on track, the outer side coupound is more like Cup2( cant comfirm) but they indeed delivery better lap time. In term of thread life and other info, didn't pay too much attention to that.
