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 4.2 / 5, the Raptor ZR A/S is ranked #42 among the 91 all-season 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 Riken was not focused on reduced road noise for the Raptor ZR A/S.
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 Raptor ZR A/S received a Treadwear Performance rating of 4.3 / 5. This ranks it #27 among the 91 all-season tires we’ve reviewed.
This rating is ‘middle-of-the-road’, this tire tends to last relatively as long as other all-season 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 300 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 300 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 300. 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!
Snow & Ice Performance
Snow/Ice Performance Rank
Snow and Ice performance is tested on a specifically designed track to simulate these environments. These ratings represent how confident drivers in these conditions felt on these tires.
The Raptor ZR A/S received a Snow & Ice Performance rating of 3.2 / 5. This ranks it #55 among the 91 all-season tires we’ve reviewed.
These tires did not perform very well in the snow and ice category. If you do see these conditions often, we recommend looking for a different tire. If you only occasionally see light snow, just be cautious on these tires when you encounter it.
Off-Road Performance Rank
The off-road ratings represent how satisfied other drivers were in these conditions. These conditions could include anything from dirt/gravel roads to extreme offroading/bouldering. If you intend to use these in more extreme conditions, we always recommend checking individual reviews on TireRack.com for specific examples.
The Raptor ZR A/S is not rated for off-road conditions, we do not recommend attempting anything beyond casual dirt roads on this tire.
Unfortunately, Riken does not offer a warranty on this tire for treadlife. However, TireRack.com usually offers their own road-hazard warranty that should take care of any unexpected potholes, screws, or other debris that causes tire damage.
