Ram 1500 Tire Size Chart

The Ram 1500 truck is available in various configurations, from the base Tradesman to the high-end Limited models, and each model may have different wheel sizes and tire options. However, in general, the 2015 Ram 1500 comes with four types of tires, depending on the trim level, bed length, and drive type:

– P265/70R17 – 17-inch wheels (steel or alloy), standard for Tradesman, Express, SLT, Outdoorsman, HFE, and Big Horn models, on two- or four-wheel drive setups.
– P275/60R20 – 20-inch wheels (alloy only), standard for Sport and Laramie models, on two- or four-wheel drive setups.
– LT265/70R17 – 17-inch wheels (alloy only), optional for SLT, Big Horn, and Lone Star models, on four-wheel drive only. This tire is more rugged and suitable for off-roading or heavy-duty hauling than the P265/70R17.
– LT275/65R18 – 18-inch wheels (alloy only), optional for SLT and Big Horn/Lone Star models, on four-wheel drive only. This tire is wider and taller than the P265/70R17 and the LT265/70R17, and may provide better traction and stability in some conditions.

Note: the tire size is usually indicated on the tire sidewall, after the letter P or LT, and consists of three numbers: the section width (in millimeters), the aspect ratio (the height of the tire as a percentage of its width), and the rim diameter (in inches).

Ram 1500 Tire Upgrades

While the OEM tires for the Ram 1500 are typically good for most daily driving needs and mild off-road activities, some Ram drivers may prefer to upgrade their tires for various reasons, such as:

– Increased performance: a more aggressive tire pattern, such as an all-terrain or mud-terrain tire, may improve the traction, acceleration, and braking ability of the Ram 1500 truck, especially on loose or slippery surfaces.
– Enhanced appearance: a larger or wider tire size, or a different tread design or sidewall lettering, can make your Ram 1500 stand out from the crowd and reflect your personal style.
– Better durability: some aftermarket tires are designed to last longer than the OEM tires, thanks to their tougher compounds, stronger construction, or puncture-resistant features.

However, before you upgrade your Ram 1500 tires, you should consider a few factors that may affect your selection, such as:

– The wheel size and offset of your Ram 1500: not all tire sizes fit all wheel sizes, and some aftermarket tires may require different wheel offsets to avoid rubbing or interference with the suspension or brake components.
– The load capacity and speed rating of the tires: you should choose tires that can support the weight and hauling/towing capacity of your Ram 1500, and that match the maximum speed limit of your vehicle’s rating, to ensure safety and compliance with regulations.
– The climate and terrain of your driving environment: depending on where you live or travel, you may need tires that can handle extreme temperatures, heavy rain, snow, ice, sand, or rocks, and that have the optimal siping, grooving, and self-cleaning features for your situation.

Some popular tire upgrades for the Ram 1500 include:

– BF Goodrich All-Terrain T/A KO2 – a versatile and durable all-terrain tire that is praised for its excellent traction, toughness, and low road noise.
– Nitto Ridge Grappler – a hybrid tire that combines the best of all-terrain and mud-terrain patterns, and is ideal for off-road adventurers who also do some highway driving.
– Toyo Open Country R/T – a rugged and aggressive tire that delivers superior off-road performance while also maintaining good on-road manners and comfort.
– Goodyear Wrangler Duratrac – a tough and reliable tire that has a unique tread pattern that can tackle mud, snow, and rocks, and is also relatively fuel efficient.
– Cooper Discoverer AT3 4S – a durable and versatile all-season tire that offers good grip, stability, and comfort on various surfaces, and is also certified for the snowflake symbol by the U.S. Tire Manufacturers Association.


To summarize, the 2015 Ram 1500 comes with several tire sizes, depending on the trim level, wheel size, and drive type. The most common tire sizes are P265/70R17 and P275/60R20, but there are also LT265/70R17 and LT275/65R18 tires available as options. If you want to upgrade your Ram 1500 tires, you should consider factors such as wheel size, load capacity, speed rating, climate, and terrain, and choose tires that fit your needs and budget.
