According to Tirerack's tests the new HTR IIIs are pretty good.

Anyone actually try these out for street, AX, DE?

 

Intresting read, i'm actually tempted to try them out, they are priced nicely

 

cant say i have... there are a few tires im willing to try but i dont see them being one of them.

 

Not a tire for myself

 

Anyone tried Sumitomo HTR Z III?

TireRack ranked it really well:

Price seems too good to be true...

Note the test was with a BMW 325, not exactly the same loads/stress as a Porsche.

UTQG seems high, though, and this usually translates to harder rubber... is this feasible: high wear AND high grip?

Anyone try these yet? Bueller, Bueller?

All you skeptics should strongly consider them. The Rennlist guys are buying them like crazy and so far the reviews have been VERY good among Porsche owners of all types. Don't be fooled by the price on these guys. They outperform many tires over twice the price in dry grip testing.

Give me a call if I can help.

 

Based on some info from TireRack, other info, and a few logic jumps, it seems the Sumitomo HRT Z III is a twin, or a better derivative, than the Dunlop SP Sport Maxx...
(Dunlop & Sumitomo share technology and have deep corporate ties.)
Anyway, it is far better rated by everyone than my current OEM Continental ContiSportContact 2.

So the TireRack tests and user reviews speak for themselves... and at half price to Pilot Sport Ribs, the price is a bonus.

Besides, you only need to wear them half out before before replacing them and ending up at the same place.

Will post an update after a bit of use.

 

i've had mine on for a couple thousand miles. i've been impressed with them. for the price, i'm happy. haven't been to track with them, so can't comment on that kind of use.

 

I have them on my 2007 M5 on the 20" wheel and I have really liked them. For the price they are EXCELLENT!

 

Update: already I like the Sumitomo HTR ZIII tires.
Sidewall was surprisingly stiff off the rim.
Once installed, the turn in felt good, noise average and overall feel was decent.
Only 500 miles but feels great commuting.
Will give them a good run soon and will try to post an update.

 

I have to agree. These tires are great. I bought them on price and wasn't expecting much, but honestly they have been one the best tire I've purchased to date including:

Potenza Pole Position
ContiSports
2 sets of SportMaxx SP (the worst performance tire I've ever owned - terrible - I think it only gets decent reviews from the brand reputation)
Pilot Sports
PZero
g-force T/A KDW

I really like the Sumitomo because it's very good in the wet as well. It also rides nice and is quiet. They held up better than most as well. I think the reviews on Tirerack gets skewed a little towards the better known brands. Most of the drivers don't push their tires at all, so if they are putting down a lot of money on "the best" name then they're going to obviously rate it high and say how great they are just to make them feel better about their purchase.

 

So far so good.

Thumbs up for the Sumitomo HTR ZIII rubber -- feels better than Contisport 2s.
Have yet to see rain or a driver event -- will update after that -- but so far so good.

 

And your reasoning is?

 

+1

If you like your PS2's and don't mind paying 1,500.00 for tires, more power to ya

 

Seems like others are happy too.
