The HTR Z5 is Sumitomo's Ultra High Performance Summer tire designed for the drivers of sports cars, sporty coupes and performance sedans looking for responsive high-speed handling and reliable traction in warm, dry and wet conditions. Like all Ultra High Performance Summer tires, the HTR Z5 is not intended to be serviced, stored nor driven in near- and below-freezing temperatures, through snow or on ice.
An aggressive, summer compound is molded into the HTR Z5's asymmetric, five-rib tread pattern. A continuous center rib aids stability and improves steering response, while the substantial shoulders improve lateral grip. Notches in the intermediate and center ribs combine with the tread compound for traction in wet conditions, and the four wide, circumferential grooves and lateral shoulder grooves evacuate standing water from the footprint for hydroplaning resistance.
The internal construction of the HTR Z5 consists of a two-ply, polyester casing supporting two high-rigidity steel belts. A full-width, nylon reinforcement ply improves high-speed stability, and a high-modulus bead insert strengthens the sidewall to aid handling.
Note:Tires exposed to temperatures of 20 degrees F (-7 degrees C) or lower must be permitted to gradually return to temperatures of at least 40 degrees F (5 degrees C) for at least 24 hours before they are flexed in any manner, such as by adjusting inflation pressures, mounting them on wheels or using them to support, roll or drive a vehicle.
Flexing of the specialized rubber compounds used in Ultra High Performance Summer tires during cold-weather use can result in irreversible compound cracking. Compound cracking is not a warrantable condition because it occurs as the result of improper use or storage. Tires exhibiting compound cracking must be replaced.
El neumático HTR Z5 de Sumitomo pertenece a la categoría: Ultra Alto Rendimiento Para Verano y fue diseñado para conductores de autos deportivos, cupé deportivo y sedanes de rendimiento, que buscan una maniobrabilidad responsiva y tracción confiable en condiciones calurosas, secas y mojadas. Como todo neumático de Ultra Alto Rendimiento Para Verano, el HTR Z5, no fue diseñado para ser reparado, guardado o utilizado en temperaturas cercanas al nivel de congelación o superficies con hielo o nieve.
Un compuesto de caucho agresivo para verano, es moldeado en un patrón asimétrico de cinco segmentos. Un segmento central continuo ayuda a la estabilidad y mejora la respuesta al girar el volante, mientras que hombros sólidos aumentan el agarre lateral. Hendiduras en el segmento central e intermedio combinadas con el compuesto de caucho de la huella, mejoran la tracción sobre superficies mojadas. Cuatro canales circunferenciales anchos y ranuras laterales, evacuan el agua estancada del área de contacto con la carretera, para aumentar la resistencia al deslizamiento sobre agua (hydroplaning).
La construcción interna del HTR Z5 cuenta con una estructura de dos capas de poliéster soportando dos correas de acero de alta rigidez. Una capa de nailon de refuerzo de lado a lado mejora la estabilidad al conducir a velocidades elevadas y refuerzos en el alambre de aro o talón fortalecen el flanco para mejorar la maniobrabilidad.
Neumáticos expuestos a temperaturas de 20 grados Fahrenheit (-7 grados Celsius) o más bajas, deben retornar gradualmente, a temperaturas de por lo menos 40 grados Fahrenheit (5 grados Celsius), por lo menos 24 horas antes de que sean doblados o flexionados en cualquier manera, como, por ejemplo, ajustando la presión de inflado, montar en rines, soportar el peso del vehículo o rodarlos al conducir.
Flexionar o doblar el caucho especializado, utilizado en los neumáticos de Rendimiento Extremo Para Verano, en condiciones frías, puede resultar en grietas irreversibles al compuesto de caucho. Si esto sucede, la garantía del producto se anula debido al uso o almacenamiento incorrecto. Neumáticos con grietas en el caucho deben ser reemplazados.

When these two wildly popular summer performance categories go head-to-head, it gives us a deeper look into what truly separates them. That helps you find the best tire for what you prioritize, whether that be on-road comfort with sporty handling or if you’ll trade off some manners for even more handling. In a packed field, with new products and first-time tires in our revamped testing platform, there were sure to be some surprises…and there were! And as always starting in 2025, you’ll see last year’s results added into the mix to see where they all stand.

...No hydroplane, good wet & dry traction...
Stock on my CX-5 and is proving to be a great tire for us. Set cruse at 72 and get 33+ mpg. No hydroplane, good wet & dry traction. Low noise unless very rough texture pavement. Have 45K and will probably get 60K. Even wear.

...However, they corner well, have very good wet and dry traction and were flawless in 2-3 of snow last winter...
The treadwear rating is the same as my Pilot Supersport Summer tires on my sports car and they wear like it. That's disappointing. However, they corner well, have very good wet and dry traction and were flawless in 2"-3" of snow last winter. They have done well enough in off-road situations like rough 2 track logging roads, but required large amounts of intervention by the traction control, sometimes. I hope to fine tires that are better off-road for the next set. I'm sure they are the reason the CX-5 feels so much like a sporty car. They are STUPID expensive.

Customers overwhelmingly rate the Sumitomo HTR Z5's dry traction 9-10, praising its excellent grip and responsive handling. A few 7s suggest minor variability, but as a summer tire, it delivers outstanding dry performance with confident cornering and stability.

...Whisper quiet on the highway, very good dry traction, comfortable enough yet pretty darn responsive for a grand touring tire...
Have to say these tires have far exceeded my tenuous expectations so far. No winter experience yet so I can't comment there but for an OE A/S tire, very happy. Whisper quiet on the highway, very good wet and dry traction, comfortable enough yet pretty darn responsive (thanks also to Mazda) for a grand touring tire...fast forward to SEP 2016! On my second set now after trying Pirelli P7 and being very disappointed in comparison. Never ran them in snow as I have a dedicated 17" package from year 1 but for 40+k miles in 3 seasons/year in the CX-5 in my experience these tires are very well matched (if not specifically designed for) the vehicle and get my high recommendation if you have that (or similar) vehicle.

...They are quiet and comfortable on on the highway...
This tire came OEM on my car. Nearing 40,000, I am trying to decide if I should nurse them through another Chicago winter. They have never proven to be capable in the snow and slide easily. They are quiet and comfortable on the highway and do well in most wet situations. Unfortunately for the price and performance, I will not be going back to this brand and will most likely replace them with the Continental Truecontact which now comes in the size I need.

...They're relatively comfortable and are a great set of tires, considering they're OEM.
These tires came with my Mazda CX-5 Grand Touring. They've lasted an amazing 68,000 miles and still have 3/32" left, so they're probably last a little past 70,000. They've done so much better than I expected in terms of mileage, but I only drive warm weather highway conditions. They're relatively comfortable and are a great set of tires, considering they're OEM.

...It does ride well in dry weather and is pretty quiet...
I am still debating how I truly feel about this tire. I did not drive in the snow too much. It does ride well in dry weather and is pretty quiet. I will keep you posted as I continue to drive and put more miles on these tires.

...Very easy/slow driver and the tread was essentially gone after 26,500 miles. Super super disappointed in the treadlife...
My wife had these tires straight from the factory. Very easy/slow driver and the tread was essentially gone after 26,500 miles. Super super disappointed in the treadlife. Not great in the snow but otherwise an excellent tire. They just didnt last and for that, I would never buy again. Not to mention, these tires are expensive!!
