The 20-inch Tires for Dodge Ram 1500 Reviews & Buyer’s Guide:

1. Falken Wildpeak AT3W All Terrain Radial Tire

Description

The WILDPEAK A/T3W is a great cold weather tire for 20” Dodge Ram 1500 applications

Performance

This model comes with a secondary bead apex; this acts as a heat shield protecting the internal tire casing leading to a durable and well-handled drive. The lower sidewall dissipates heat, this protects the internal tire parts and maintains a cool drive cycle.

The 3D canyons sipe technology uses shoulder interlocks to resist high torque wear; this also increases the road handling and tire stability. The tire tread comes with rigged blocks that include support ramps and step‐down features giving additional rigidity across the contact patch. This also prevents grit and stones from accumulating between the grooves.

There is model comes with an aggressive upper sidewall and offset shoulder block to protect the tire from sharp objects further.

Recommendations

This is a well-priced deal, the tire is above average and comes with a good middle range price that delivers on value per dollar. This is a great cold weather tire.

2. Mickey Thompson 90000029948 Mickey Thompson Deegan 38 All-Terrain Tire

Description

The Deegan 38 All Terrain by Mickey Thompson comes with a 55,000-mile limited treadwear warranty for “LT” sizes.

Performance

This model has a silica-reinforced tread compound tread that delivers all-weather performance. There is a cut/chip resistance design that adds tire longevity, and the high-tensile 2-Ply body cord is an integral part of the construct that is used to the reduced weight, increased durability and improved the ride performance.

The design includes a variable-draft angle and treads edge chamfer which combined to reduce stone retention and maintain a clean and clear grip of the surface. The angled shoulder scallops and two-pitch SideBiter® pattern are engineered for off-road traction and perform exceptionally well in the most adverse of conditions.

This model comes with tread element tie-bars that are installed to improve stability and drive responsiveness.

Recommendations

When it comes with an upper medium quality price, these tires for the Ram 1500 are there as leaders of the pack. While it does come with a reasonable price tag, it actually delivers all that it claims to do, and as such, is an exceptional investment for the long haul and off-road driver.

3. Nitto NT420S All-Season Radial Tire

Description

The Nitto NT420S All-Season Radial Tire is a racing/performance tire that comes with a W rated speed.

Performance

This is a dry performance tire that is used for track performance but makes no mistake; it is also designed to work extremely well with wet conditions too. This 420S model comes with large outer tread blocks that increase the surface contact area deliver a much more controlled cornering solution at high speeds. The asymmetrical, non-directional tread pattern provides cross-rotation performance reduces irregular wear, resulting in an even wear distribution for longevity.

The tread pattern siping is what gives that additional wet surface traction, and the center tread pattern is designed to channel water for improved handling. This model also comes with a slanted three-dimensional tread block design that is used to reduce flex for improved handling.

Recommendations

This is a budget-friendly tire, and will not burn holes in your pocket, but should be used to burn rubber on the track. Again, the price is extremely low, and this makes for a great dry weather hard surface solution.

4. Dick Cepek Fun Country All-Terrain Radial Tire

Description

OK, so now we have the Dick Cepek Fun Country All-Terrain Radial Tire, which is aptly named since it’s a highly rated, high priced tire of extreme performance capabilities.

Performance

This is a hybrid, mud, and snow rated tire that is engineered to deliver excellence in all areas of operation. The design features uniquely designed interlocking tread lugs with narrow sipes that deliver exceptional surface grip. There are wide alternating tread grooves combined with an excellent tread design giving you a constant and firm contact patch responding to changing terrain conditions.

The tire has a computer-optimized tread pitch sequence that is designed to provide a quieter street ride, and the reinforced three-ply sidewall comes with the proprietary Dick Cepek alternating Sidebiters™ which protects the tires from sharp objects and puncturing.

Recommendations

This is the tire all tires aspire to be, it’s a hybrid for all weather and terrain, and the price is not a reflection of the brand but a reflection of the total quality and performance that this tire delivers. In my own words, if you can afford it, buy it, and you will never want to replace it.

5. Cooper Tires Discoverer S/T Maxx All-Terrain Radial Tire

Description

The Discoverer S/T MAXX™ is a tough terrain first with on-road performance tire.

Performance

If you need an off-road performance tire, then this hybrid 4-5 rib design with low tread pattern noise will deliver the goods. This is an even wear tire and comes with the dual draft and non-parallel grooved walls. This design reduces stone retention and also protects from chipping and cutting.

The design includes stone ejector ribs that mechanically remove stones as the tire performs, and the proprietary Armor Tek3® construction is a feat of engineering designed to extend life for long-term off-road usage.

Recommendations

This is a fine example of an off-road tire that is suitable for road applications too. However, it is a shame to waste this on an all on-road application. This is truly suitable for off-road usage and should be considered as another well-priced leader of off-road performance power.

Dodge Ram 1500 Tires FAQ

Tire Size Markings

The first marking you will see is a letter, such as “P” which stands for Passenger Car, or “LT” which stands for light truck, ST for special trailer and T which stands for temporary (spare tire). This appears on US markings but not on European types.

The second marking is the section width of the tread in mm, so if you see the number 260 it means 260mm section width tread. This marking is separated by a “/,” and then a two digit number appears. This is the third marking.
The third marking is the aspect ratio, this is the height of the sidewall as a percentage of the tread width, for instance, if the aspect ratio is 65, then it means it is 65% of 250 which is 162.5.

The next marking you see is a letter; this is the speed rating, for instance, Z =Speed Rating, S = 112mph, T = 118mph, etc. If you see a Z, it will be followed by another letter, usually W or Y speed rating that comes after the load index, so you know the exact speed of the tires rating.

The next marking is a letter followed by numbers, this is the construction letter and includes B for bias belt, the sidewalls are the same material as the tread, D for diagonal, R for radial and if there is no letter, then it’s a cross-ply tire.

The number after the letter denotes the wheel diameter in inches, so if you see 20, it stands for a tire that fits a 20” wheel.

Now we come to the load index marking, this is between two to three digits, and this is an indicator of the maximum load capacity that the tire can take., Never buy a load capacity that is lower than your vehicles designated load.

For instance, the load index of 60 represents 250 kg (550 lb), and the load index of 127 represents 1,750 kg (3,860 lb).

Now we come to the speed rating marking; it is not always included. The speed rating is a letter, and this represents the maximum speed that the tire can be driven with. For instance, A1 is 3mph, G is 56mph, and W is over 168mph Z stands for racing and will come with either a W or Y rating after it.

Those are the markings on tires, so when you see this:

LT215/85R1 it means Light Truck, 215mm tread width 85% height to width ratio, Radial with 16” wheel width.

U.S. Department of Transportation Markings (DOT)

All vehicles in the USA must have a DOT marking, this DOT number means that the tire conforms to the DOT regulations. The DOT code is made up of the 2-digit manufacturer code, the 2 sizes followed by the week and year of manufacture in a four-digit code.

Uniform Tire Quality Grading (UTQG) Marking

The Department of Transportation also requires all manufacturers to grade their tires under the Uniform Tire Quality Grade (UTQG) system. This system defines ratings for treadwear, traction, and temperature resistance.

The treadwear rating number refers to the durability of the tire; this is a loosely interpreted rating since the DOT does not test the tires, this is done by the manufacturer.

The traction rating letter code refers to the tire’s straight-line stopping power on wet asphalt and concrete. This test does not include cornering or hydroplaning resistance in wet conditions, neither does it address braking and handling in dry conditions. This rating is either AA, A, B or C, where AA is the highest rating.

The temperature rating which is rated between A to C refers to the tire’s thermal resistance when driven at high speeds; A is the highest rating.

Maximum Inflation Pressure and Load

The PSI (pounds per square inch) is maximum inflation pressure number that the tire can handle. Always refer to the owner’s manual for tire pressure ratings.

The maximum load number represents the weight in pounds that the tire can carry individually when inflated at maximum pressure. Always match a load of your tire to the owner’s manual tire load indication.
