Tires with varying treadwear ratings

[FSUZ33]

Someone I work with is running Hankooks (Ventus S1 Evo 3) and I had never checked out their lineup so I took a look on Tire Rack. What stuck out to me was the treadwear rating for that specific tire varied a pretty good bit based on the size. I believe it spanned 180 to 420 on treadwear. Traction and Temp varied as well, but all were either A or AA for both ratings.

I'm not a student of tires and tire technology, but I've done my share of research over the last 30 years, and I don't recall a specific model tire having treadwear ratings that varied like that. I'm used to checking a tire's UTQG and assuming it's the same compound across that model. Have I been mistaken this whole time? Is that normal for certain brands or types of tires within the broad 'performance car' tire segment to have varying ratings like that?

My thought is if you have a car that already tends to oversteer like an S2K, and you're not paying attention ands throw 180TW on the front and 420tw on the rear, that could create some pretty ungood characteristics, correct?

I'd agree with all your points above; also surprised. Your S2k example is the first thing that came into my mind as well.

I would buy an S2K, only if "TAILHPY" is available as a personalized plate.

I lost the rear on mine at 90+ once! Talk about a pucker moment...

This is accurate as far as some variation with TW rating, but I have not ever seen a tire deviate that much, normally like 200, 220, 240 or something minor.

Ideal setups are "square" for track days at least. Which is not the Z, but oh well, it does fine. Something like drag racing, this could be fine.

Don't get me wrong though, I'd take an S2K any day. Will always love Hondas.
