Firestone Destination AT and Firestone Destination XTare both All-Terrain tires developed for drivers who want to go anywhere dependably. The tread depth and the void ratio of XT is higher than AT, which allows lesser contact patch with the road, making it best suited for off-road driving. While AT tread depth and the void ratio is comparatively lower allowing greater contact patch with the road, making it better for on-road traction.
The higher built strength and the open tread design of XT boost the off-road capabilities on the tire. For a further in-depth comparison between these two tires, continue reading.
Comparing Firestone Destination AT with
The AT has a tread compound molded into an asymmetric all-terrain tread pattern. AT all-terrain tires have center rib flanked by independent intermediate blocks and wrap around shoulders that combine highway stability with off-road traction. Circumferential and lower void ratio as compared to XT enhances its traction while on-road and faceted tread blocks and sipes improve wet grip and handling. Narrow grooves are not efficient in soft snow, mud, and gravel traction as they can’t maintain grip. The closed shoulder design further hinders the flow of mud through its grooves. The higher contact is, however, useful on icy roads as it allows the tire to firmly grasp the road, increasing its traction on ice. The tire has weaker built which doesn’t allow the tire to perform well on rocks as it is vulnerable to trail damages like cuts and chips. The small stone ejectors are also unable to keep all the stones from getting stuck inside the grooves. This decreases the dependency of this tire on rocks. Since the tire has weaker built, it is unable to resist wear and tear, decreasing the tire’s durability and mileage. The tire is comfortable on-road due to lower noise level but is not reliable off-road due to inability to withstand jerks.
XT has specially formulated rubber compound molded into an aggressive symmetric pattern. The higher void ratio allows less contact with the road, making its on-road traction inferior to AT. Its void ratio is higher plus it has deeper sipes. The higher tread depth and the numerous sipes help to wipe water easily. The wider grooves present help remove soft snow and mud easily through its tread. The aggressive off-shoulder tread design creates a biting edge with mud and snow condition, it also helps with mud passing through its grooves. XT is certified with severe snow service rated and is branded with the three-peak mountain snowflake (3PMSF) symbol but lacks on ice due to the absence of a decent contact patch, making it slip. The higher build quality increases its treadwear resistance which in turn improves its durability and mileage. The tire is noisier on road but dampens the impact of shocks to provide a comfortable off-road journey.
On-Road traction comparison:
AT has a lower void ratio that allows decent contact between the tread blocks and the road. Due to maximum contact with the surface, it has a great advantage over on-road traction making it more of an on-road-friendly tire. The Narrow grooves and the decent number of sipes give this tire capability to wipe away water but they are not efficient enough to handle extreme wet conditions. Therefore, it is lacking when it comes to wet traction but is superior in the case of on-road dry traction.
The higher void ratio of XT does not allow a large contact area between the blocks and the road, making it unfavorable for on-road traction as compared to AT. However, in the wet condition, the wider grooves along with deep sipes allow water to easily pass through them giving better grip.
Off-Road traction comparison:
AT has a lower void ratio as compared to XT, making the tire less effective in mud conditions. The narrow grooves don’t allow easy navigation through the mud because the mud gets stuck inside them, decreasing its gripping capability. The shoulder design used in AT is less optimized which further hinders the traction of mud, making it an undesirable tire on mud terrain.
The higher void ratio of XT allows easy navigation through the mud by effectively throwing it backward with the help of wider grooves. The aggressive symmetric tread pattern and off-shoulder design help slide and clear the mud from the tires. Its shoulder design increases the biting strength needed to find any available loose variant, giving the tire a great edge over muddy terrain.
AT has a lower void ratio which makes the tire lack in the soft snow. The narrow grooves do throw soft snow backward, moving the tire forward but they are not as effective as XT because XT tire has been certified with a 3PMSF rating.
The wider grooves and deeper sipes of XT help to navigate through soft snow easily. Just like mud the grooves throw snow backward and improve the traction of the vehicle. On other hand, the tire struggles to maintain a grip on ice due to its lower contact patch.
The AT has a lower void ratio providing lesser grip on rocks. Stone ejectors are not quite efficient which makes the tire lesser effective against avoiding the stones from getting stuck into the grooves. The built quality and protection against pebbles and sharp rocks is also not satisfactory, decreasing the credibility of the tire on rocks.
XT has a higher void ratio and aggressive symmetric shoulder lugs with decent shape and size which enables better biting grip for tricky angles on rocky terrain. Stone ejectors used in this tire are effective at avoiding the stones from getting stuck inside the grooves. The thick sidewall protector shoulder guard and protect the tire against impacts and provide protection from cuts, making it a more attractive option for rocks traction.
XT has wider grooves which cause more air particles to get trapped inside its grooves and bounce back and forth off its walls, producing noise and compromising the comfort level during on-road travel. Whereas, during off-roading wider grooves act as shock absorbers making the ride more comfortable.
In comparison, AT is less noisy as compared to XT because of the lower void ratio which causes a lower amount of air particles to get trapped between the grooves producing lesser noise during traveling at high speed, making it more comfortable on-road But during off-road traction, the comfort level is compromised because of the inability to narrow grooves to absorb shocks efficiently.
Durability and treadwear:
In the case of AT, the contact patch is higher increasing the tire’s rolling resistance and decreasing the force needed to keep the tire rolling. Due to higher rolling resistance, the treadwear is high which is indirectly proportional to durability and mileage. The body of AT consists two-ply polyester cord casing supporting two high-tensile steel belts. A nylon reinforcement ply provides durability and higher speed capability.
XT has the lower contact patch with the road because of the higher void ratio making the tire’s rolling resistance minimum, which is the force required to keep the tire rolling. Due to low rolling resistance, the treadwear is also low, making the durability and mileage higher. XT internal construction includes twin, high-tensile steel cord belts reinforced with spirally wrapped nylon on top of a polyester cord casing to combine strength, durability, and ride comfort.
The price of XT is higher as compared to AT because of the material used for internal construction and due to optimized tread design. The mileage and durability of XT is also higher as compared to that of AT.
- Both tires are All-Terrain.
- When it comes to on-road dry traction AT performance is quite elegant.
- The off-road performance of the XT is more superior as compared to AT.
- XT performance is way better in snow and mud as compared to AT.
- The durability and treadwear resistance of XT is way better as compared to AT.
- In terms of price, AT is a little cheaper in comparison with the XT.
