Both are specialized summer tires where PZ4 is a max performance tire that has a wonderful grip and commanded handling over the paved tracks.
On the other side, Premitra provides better resistance against aquaplaning and a lower rolling resistance, decreasing fuel consumption as well as its treadwear.
Thus, verifies itself as a good touring tire.
PZ4 has an asymmetrical tread design in which the central part is characterized by the close placement of box-shaped blocks in three rows.
Four circumferential grooves run along with the tread continually, moreover, its shoulders have several lateral grooves which are linked with central voids, and a narrow longitudinal groove also passes through the inboard shoulder.
Many rectilinear sipes are marked multi-directionally over its blocks to account for water channeling. Shoulder blocks of one side are bulky squares while the other one characterizes compactly placed rectangular elements.
Premitra exhibits an asymmetrical and deeper tread with three ribs and four grooves arranged circumferentially without any lateral interruptions. Its void ratio is represented by central grooves as well as numerous lateral channels among shoulder blocks, however, its voids are deeper than its competitor.
Linear and bent sipes of different widths are marked over its central ribs and marginal blocks. Its shoulders have an optimized surface area, but its size is smaller than that of its competitor.
Road Grip Comparison
Large, box-shaped blocks of PZ4 make its grip firm on the dry road, as much of its surface area is directly connected with the road.
Its braking distance is marked 115 feet over a dry road.
While moving over wet tracks, its circumferential grooves and horizontal sipes wipe away water and help bulky central ribs to grip over the paved surface firmly, leading to a lesser stopping distance on wet pavements as well.
It stops after 153 feet on a wet track.
Premitra shows a comparatively lower grip over the dry paved surface, owing to the open pattern of its tread. It has a lower contact patch because of the relatively minimized width of its central ribs and large voids between them.
Its stopping distance on a dry road is 117 feet.
On a wet road, its deeper voids and wide sipes over the ribs efficiently wipe the water away from the tread and provide a safe journey, however, decreased contact patch causes a lower wet grip in comparison. Its wet braking is 182 feet.
PZ4 takes the advantage of a relatively larger size of its shoulder blocks to maintain resolute grip when the vehicle turns around a corner. Hence, it shows a precise and fully commanded steer response.
Its average speed for dry handling is 62 mph. On a wet road, the efficient design of its tread channels helps it to pass the underneath water quickly so that its big shoulder lugs can sustain a sturdy grip while taking turns.
It manages good wet handling with an average speed of 54.7 mph.
Maxxis shows a reliable performance while taking turns as its shoulders have a decent area to form a connection with the ground, however, their size is smaller in comparison which eventually accounts for a less precise handling response than the competitor due to the loss of grip.
Its dry handling average speed is recorded at 61 mph. While turning over the wet road, water quickly finds a way out through its deeper channels, nonetheless, small shoulder blocks show comparatively less accurate steer management. Its average speed for wet handling is 51.1 mph.
Comparison of Hydroplaning Resistance
PZ4 stands behind in terms of preventing aquaplaning on wet pavement because its tread voids are less deeper.
Although, linear slit-like sipes and mutually linked longitudinal and lateral grooves act efficiently to account for reliable resistance against hydroplaning, yet minimal void depth decreases water channeling ability. It has a float speed of 55 mph.
Premitra resists hydroplaning more efficiently as it has comparatively deeper grooves which offer a relatively larger volume to channel water through the threads.
Linear and bent sipes of varied widths also help in wiping water off and reduce the risk of sliding on wet roads. It has a float speed of 55.5 mph.
Comparison of Rolling Resistance
PZ4 faces higher rolling resistance due to its higher contact patch, as a large surface area of tread, is being scrubbed over the road, more friction arises and a larger amount of energy is used to keep this tire rolling.
Its rolling resistance is 8.7 kg/t. Fuel efficiency is decreased as a result of higher energy consumption.
HP5 has lower rolling in comparison, as lesser area of its tread touches the ground, resultantly lower rolling friction arises and a minimal amount of energy is used to overcome it.
In the test, its rolling resistance is measured at 8 kg/t. Hence, it is more fuel-efficient than its competitor.
Comfort and Noise Comparison
PZ4 produces a loud noise while rolling as compared to its competitor, its noise level is recorded 73 dB in the test.
Yet, it offers more driving comfort due to its efficient on-road grip which is credited to a higher contact patch.
Premitra is a quieter tire in comparison and it marks a lower level at the decibel scale. Its noise level is 71.6 dB.
However, it does not offer the comfort of driving as supreme as its competitor because less traction is provided by a minimal contact patch.
Durability and Treadwear Differences
PZ4 is a fairly durable option among max performance tires but its design; optimized for a better grip makes it wear down faster as compared to its competitor.
Its tread is molded out from a silica and carbon black compound with an internal structure of hybrid Nylon and Kevlar ZeroDegree cap ply along with twin steel belt casing to ensure a firm performance all the time.
However, it lasts for a lesser duration as tread rubber is consumed quickly due to higher rolling resistance.
Premitra shows a comparatively longer tread life due to its lower contact patch.
Due to a lower contact patch, its tread faces lower rolling resistance, thus, it wears down slowly and gradually. It has a silica-based tread rubber that remains functional even in high temperatures
What about the cost?
PZ4 is expensive comparatively but its higher price is well justified by its awesome traction capabilities.
On the other side, Permitra stands more beneficial economically as not only its price is lesser but also it saves money due to its better fuel economy and longer tread life.
- PZ4 is a max performance tire while HP5 is a touring summer tire.
- PZ4 shows superior traction on both wet and dry roads.
- Premitra has a better hydroplaning resistivity in comparison.
- HP5 makes less noise but its comfort level is lower.
- PZ4 encounters higher rolling resistance than its competitor.
- Premitra costs a lesser amount and stands durable in comparison.
