...Wet traction is very good and I don't sense any hydroplaning unless the roads are extremely wet.
Good value for a summer tire. Overall the treadwear is good. Due to the staggered tire size on my car, I cannot do a traditional rotation. Steering input is very responsive. I do have a bit more front weight than the traditional Boxster due to some mods in the back. This gives me very responsive cornering with little to no under steer. Wet traction is very good and I don't sense any hydroplaning unless the roads are extremely wet.

...Together, these tires offer great wet and dry traction along with a responsive steering feel. These tires perform and ride just as good as they look.
This is the second set of Sumitomo HTR Z5 front tires purchased for the 2007 Mustang GT and they have performed excellently. We run the Sumitomo HTR tires in the rear, just a bigger size for the staggered wheel setup. Together, these tires offer great wet and dry traction along with a responsive steering feel. These tires perform and ride just as good as they look.

...The ride quality and noise levels are great, while providing excellent response to the driver.
I have used these tires on the front of my 2007 Mustang GT, and they have performed well over the past four years. This is a second set for the front, and I run the same tire (just a bigger size) in the rear, and I have been pleased with their wet and dry performance. The ride quality and noise levels are great, while providing excellent response to the driver.

...They're quiet, comfortable, and seem to be wearing nicely...
These are my “mess around” tires that I don’t really care about since they’re so cheap relative to all other options. I purchased these so I wouldn’t feel bad power sliding around with them.
They’re not as good as a PS4S or Indy500 (my benchmark 300tw tires). They grease out very quickly and they have soft sidewalls making steering input a bit dull.
That said, they’re so cheap I think they’d be perfectly adequate for a daily driver tire that’s able to preform better than an all-season. They’re quiet, comfortable, and seem to be wearing nicely.
I’m not sure if I’d purchase these again. If they didn’t handle heat so poorly I think they’d be acceptable at this price range. Don’t plan on driving more than 7/10ths with these tires.

Most customers rate treadwear highly with scores of 8-10, highlighting excellent durability for a performance-focused summer tire. A few lower scores suggest varied experiences, but the majority praise its long-lasting capability in intended conditions.

My fourth set of Sumitomo tires on 2, 2000 Porsche Boxter S's that I've owned. Half the price of the competition, twice the tread life and overall 99% of the dedicated track day tires. What's not to like?
