Does anyone have experience with Sumitomo HTR+'s?
So, I was all excited about getting some new tires for the upcoming fall season. I ordered the Sumitomo HTR+'s from Tire Rack - "ultra high performance all season." As soon as I got them mounted I could already tell that there was something wrong. It basically makes my car feel like all the shocks are blown, or as if I was driving on solid marshmellow tires. At freeway speeds they aren't even safe. The car slides around from left to right without moving the steering wheel at all. In the corners it's really bad. It takes like an extra second for any of the input to reach the road, and coming out of the corners the tires throw the weight of the car nearly off the road.
Does anyone have any experience with these tires or can offer any advice?
Thanks in advance.

They have about 320 miles on them so far but I havent really noticed any break-in improvement yet. They are 205/55/16 for the stock wheels. I have tried running 32psi in the front and 30 in the back as well as 36 in the front and 33 in the back. Both ways still have all the problems. What got kind of break in period (miles?) did you guys see for your tires?
I called Tire Rack and they said to just run some more miles on them with a bit more pressure, so we'll see if that helps.

Check the sidewall for the max inflation pressure and don't go above that (cold).

I had them in 225/50 on stock rims and loved them. I ran 38/36 in them and 42/38 st autoXs. The side walls are not that stiff but Ok what are you compairing them to? They blow the RE92s away. They are not that good in the snow and when they get close to waring out they loose grip and get loud. But they are very good for how cheap they are.

Thanks for the info. I drive really hard though. So, I am comparing them to tires like SO3s and Azenis Sports that totally outclass them. Guess that was my first mistake though huh?
I got another pair of tires/wheels for the summer weather and put the Sumitomos on reserve for winter/dirt duty.

I actually HAVE the sumitomo HTR + on my EVO for this winter and I would say that at 150 miles and hour, They are a really good tire.. True they are NO where Near the sticky substance of a true performance(Summer) tire.. but to me Sumitomo is a great tire..
Believe me ... I understand your concern .. EVO's come with a very, very sticky tire.. (Yokohama-Advan's) so I undertand...
Good Luck ..

I have the HTR-Z II's on my 17" BBS RG-R's sized 225-45-17 and I have been really pleased with them. Good dry grip, stiff enough sidewall and decent wet grip. Maybe you got a bad set or they suck with a 55 height sidewall?
