i have about 5k on my htr II and they seem to do well. They do not like damp pavement at all.

I don't know if they are HTR I's, II's, or III's Z's on the 02 I bought in August. Picked it up and drove throught 2 states in the rain with no problem. Weather cleared for Fri. rush hour in Chicago. Next day cruise through Wi., corner of Iowa, and MN good, with one problem that still re occurs. I live in North Dakota and the car has been a daily driver all but maybe 5 days because of blizzards. The traction is better with the HTR's than my pickup has in 2 wheel drive.

The secret is to drive for the conditions and not the cars maximum potential.

Oh, and the re occurring problem is other drivers pulling in front of me to show how fast they are and then the drivers slowing down because they don't have the ability to handle the limited number of curves we have in this state of flat straight roads, when the Boxster wants to start showing it's stuff.

When I got the car HTR 3 (17") were mounted. I was really concerned but have to admit that these tires are really good. Grip is good, handle crisp, comfortable and, they don't squeal as much as other tires when pushed. Can't comment on wet, though.

Keep in mind that there are very few "bad" tires out there, only advice, stay away from anything Chinese!

I have a 2000 Boxster.......my car(women driver) is my every day car in Dallas Tx...so my concerns are a tire that holds up to the heat and has traction in the rain. I do not race but have a heavy foot and tend to always drive over the speed limit. Texas some times has hard rains and this last year 104 temps and snow twice (which is unusual). The HTR Z III was recommended but would rather spend more if I am not going to be safe in the rain...but will also be sad if I spend a bunch of money for a tire that wears quickly. Had Toyos from Kaufman Tire who is no longer in business....belts had separated in the back tire and then this last weekend I had a blow out on the highway...so need to get all or at least two. Any comments would be appreciated...

I was really impressed with the Sumis at a driver's skills a few months ago and especially my DE yesterday. Really sticky when they heat up. The track has some choppy, beat up sections through a turn and the car didn't feel unsettled at all. The release of grip at the limit was communicated very clearly. They inspired alot of confidence. No strange wear or damage either. I'm really glad I went with these tires.

The guys at the track in College Station (similar heat and climate issues you face in Dallas) are all very impressed with Hankook Ventus V12s. They perform as well as Michelin PS2s at half the price on the boxster.

I'm planning on buying two sets of them, for my 18 inch street rims and my 17 inch track rims.

My Sumi's were very good in dry and ok in the rain. If you get a lot of standing water when it rains there may be a couple better choices: Hankook V12 are about the same price and better in the rain. Dunlop Direzza Z1 Star Spec might be the best rain tire I ever used and they are amazing on hot dry pavement as well. Dunlop Star Specs will not last as long as the Sumi's and are a bit more money.

My car came with mis-matched tires. Don't ask.....

Anyway, since I have 2 hankook tires, I am gonna get 2 more hankooks for the front.

I have a brand new sumi for the front if someone wants it. Throw me an offer. I'm in Wisconsin.

Just a FYI NTB has a buy 2 get 2 free on the sumi htr Z III.

Set of 4 installed around $760 with 3 yr alignment. Hard to beat that.
