The Direzza ZII Star Spec by Dunlop is a summer tire with an overall rating of 4.1 / 5. This places it in spot #18 among the 53 summer tires we’ve reviewed.
Dry Performance Rank

Wet Performance Rank
The Direzza ZII Star Spec received a Wet Performance rating of 3.7 / 5. This ranks it #35 among the 53 summer tires we’ve reviewed.
Considering this, you may be underwhelmed by its performance on wet roads. Other buyers have not been overly pleased with their traction and hydroplane resistance.
Comfort Performance Rank
“Comfort” performance relates to the tire’s quietness, and smoothness. Better ratings will keep tire ‘roar’ or road-noise to a minimum. Great for luxury cars, or anybody looking for a quieter cabin.
With a Comfort Performance rating of 3.7 / 5, the Direzza ZII Star Spec is ranked #32 among the 53 summer tires we’ve reviewed.
This rating implies the tire is louder than most on the road, and/or typical buyers of this tire were generally used to quieter and smoother tires. It’s likely Dunlop was not focused on reduced road noise for the Direzza ZII Star Spec.
Treadwear Performance Rank
Treadwear performance is a measure of how well the tire matched up to customers’ expectations of how many miles they will last. Keep in mind, this rating can be influenced significantly by users giving it 1-star or 5-stars because expectations were too extreme. Maybe their last set of tires lasted 100,000 miles and they now think all tires will last that long (that’s extremely rare). Or perhaps their alignment was really off, causing them to wear out in only a few thousand miles.
The Direzza ZII Star Spec received a Treadwear Performance rating of 4 / 5. This ranks it #11 among the 53 summer tires we’ve reviewed.
This rating is ‘middle-of-the-road’, this tire tends to last relatively as long as other summer tires. Without knowing one’s specific expectations, it’s likely that a typical buyer will be happy with the mileage, but not super impressed either.
UTQG Rating: What does 200 A A Mean?
The UTQG Specification is also relevant to discuss here. This is a specification provided by the manufacturer after testing. The rating for this tire is 200 A A. There are three parts to this specification: treadwear grade, traction grade, and temperature grade (in that order).
The treadwear grade for this tire is 200. This score implies the tire is relatively soft, and will wear pretty quickly. Usually a trade-off for excellent dry-road traction.
The traction grade for this tire is ‘A’. This is a great rating, and implies the tire can handle high g-forces before starting to skid.
The temperature grade for this tire is ‘A’. This rating refers to how well the tire dissipates heat at high speeds. If the tire gets too hot at high speeds, it may come apart. Keep in mind, these speeds are very high, and any tire manufactured these days is capable of maintaining highway speeds up to 80mph.
This is the highest temperature grade rating. An A rating here suggests the tire is temperature-stable at speeds over 115mph. Slow down!
