Comparing General Altimax RT43 vs Altimax RT45

Share This Post

The General Altimax RT43 and RT45 tires have a lot to offer. Both tires provide a super quiet drive on paved roads and excel in smoothing out bumps, making for a more comfortable journey.

The value you get for the price is outstanding. They’re up to 30% cheaper than similar tires from brands like Michelin or Bridgestone, without skimping on performance.

Durability is another highlight. You won’t need to think about replacing these tires anytime soon. Both come with a generous 75,000-mile warranty, which is impressive for mid-range tires.

But, does this mean you shouldn’t consider switching from the RT43 to the RT45? Hold on a minute. The RT45 retains everything drivers loved about the RT43 but adds even more improvements, including better wear resistance and more.

General Altimax RT43: A Time-Tested Favorite

The General Altimax RT43, launched in 2013, is a staple in the mid-range, all-season touring tire category. It’s so well-regarded that when General Tire hinted at replacing it, dealers pushed back.

What makes the RT43 stand out? Its balanced performance is a key factor. It’s reliable on both dry and wet surfaces, and it even stops quickly on snow and ice, which is impressive for a tire in its class.

Ride comfort is another big plus. On paved roads, it offers a smooth experience with very little vibration. It’s also responsive, giving drivers a decent sense of the road, although it doesn’t match the feedback you’d get from a sport tire.

The RT43 also shines with its 75,000-mile treadwear warranty, a standout offer in this segment. This longevity is especially notable given its affordability compared to other long-lasting tires that can cost up to three times more.

General Altimax RT45: Building on Success

Launched in July 2022, the General Altimax RT45 is praised as a worthy successor to the RT43. It not only retains many of the admired features of its predecessor but also introduces several enhancements.

Key upgrades include an all-season tread compound and an asymmetric tread design, which ensure solid traction across different weather conditions. Its large circumferential grooves are great at preventing aquaplaning by moving water away efficiently.

The RT45 boasts a flatter contour than the RT43, according to General, leading to a 10% improvement in wear. This suggests the RT45 will likely outlast the RT43, offering even greater value over its lifespan.

However, the RT45’s treadwear warranty mirrors that of the RT43, maxing out at 75,000 miles. A longer warranty would have lent more weight to the claims of improved wear, making it an even more compelling choice for drivers looking for durability and performance.

What Are The Differences?

Now, let’s dive into the details and compare the General Altimax RT43 and Altimax RT45 to help you decide which tire best suits your vehicle.

Off-Road Performance

Winner: It’s a tie

The Altimax RT43 and Altimax RT45 aren’t built for the rugged paths of off-roading. Their tread designs lack the deep, aggressive lugs that are essential for navigating through tough terrains, which means they aren’t the best fit for adventures away from paved roads. Plus, the thin sidewalls on these tires are more prone to damage from sharp objects, potentially leading to costly replacements.

If off-road adventures are your aim, look towards mud-terrain or all-terrain tires instead. Mud terrain tires are ideal if you have a separate set for daily driving and need tires that excel in challenging terrains. But if you’re after versatility for both highway drives and mild off-roading, all-terrain tires are your go-to.

On-Road Performance

How Do They Perform in Dry Conditions?

Winner: General Altimax RT45

On dry roads, both tires showcase commendable performance, but the Altimax RT45 edges out slightly ahead due to its exceptional qualities.

The Altimax RT43 is celebrated for its superior grip on dry surfaces, ensuring a secure connection with the road even under pressure. Its remarkable stopping distances are a testament to its reliability, offering safe braking capabilities at varying speeds. The Altimax RT45 shares these admirable traits, excelling in dry road performance much like its predecessor.

However, the RT45 stands out for its ability to match the road grip of premium all-season touring tires, which is impressive given its significantly lower price point. Moreover, it finds a sweet spot between grip and tire wear, indicating that it can last longer without sacrificing performance.

This delicate balance of durability and handling crowns the Altimax RT45 as the preferred option for those prioritizing performance on dry roads.

How Do They Perform on Wet Roads?

Winner: General Altimax RT45

Do you find yourself driving often in the rain? If so, the Altimax RT45 is your go-to option. Here’s why:

The Altimax RT45 cuts down on wet braking distances. When it was launched, General shared that the RT45 could stop quicker on wet roads than the RT43. This has been backed up by independent testing.

It’s tougher against hydroplaning. Thanks to its superior hydroplaning resistance, the RT45 keeps in closer contact with the road. This means you get a firmer grip and a safer ride on those rainy days.

It boasts more sipes for extra grip. Comparing the two, you’ll spot more biting edges on the RT45. This is great news for its grip and how it handles wet surfaces.

However, keep in mind that while these improvements – shorter stopping times, better stability, enhanced grip – are significant, they might not jump out at you. Those familiar with the Altimax RT43 may not immediately notice the upgrades in the newer model.

Are They Good in the Handling Department?

Winner: General Altimax RT45

In terms of handling, the Altimax RT45 is a step ahead. This is largely thanks to its flatter contour. This design helps evenly spread out the forces (like accelerating, braking, and cornering) applied by your car. As a result, you get smoother control, especially when you need to change lanes or corner quickly.

Another plus is its larger circumferential grooves. These enhance its ability to move water away from the tire, improving road grip and handling in wet conditions.

Snow Performance

Winner: General Altimax RT45

Facing heavy snowfalls? The Altimax RT45 should be your tire of choice.

Its open shoulder slots and grooves keep it stable on snow. These features add extra biting points on the tire’s tread, ensuring consistent grip on snowy roads.

Moreover, these grooves help prevent snow and ice accumulation in the tire’s footprint, avoiding a slippery layer between the tire and the road. This ensures reliable traction even in severe winter weather.

On the other hand, the Altimax RT43 doesn’t have the necessary design features for optimal performance in tough winter conditions.

Treadwear and Durability

Winner: It’s a Tie

Customers have reported that both of these tires exceed their treadwear warranties. This is impressive because each is guaranteed to last up to 75,000 miles—a standout promise for tires in their price range.

What this means is you can trust these tires to hold up very well over time. For example, one customer mentioned their tires still had full tread after driving 40,000 kilometers.

Another savvy driver shared a pro tip: rotate your tires every 7,000 miles or less to avoid uneven wear, ensuring they last even longer.


Winner: It’s a Tie

Both tire models are known for their smooth rides.

The Altimax RT43 shines in making road bumps nearly disappear, offering exceptional comfort. While you might notice a jolt from the odd pothole, generally, you’ll enjoy a vibration-free experience on smooth roads.

The Altimax RT45, too, provides a smooth journey. When combined with a solid suspension system, it’s excellent at soaking up road noise, making for a peaceful ride.

So, when it comes to comfort, there’s little to choose between the two.


Winner: Altimax RT45

As expected, the Altimax RT45 comes with a higher price tag than the RT43.

This shouldn’t come as a shock since the RT45 is the newer model, launched just last year. It benefits from the latest advancements in tire technology and materials not available when the RT43 was released in July 2013.
