245/75R17 Tire Width, Sidewall, and Rim Size

Measured across its tread, a 245/75R17 tire is about 9.6 inches wide, with a sidewall height of roughly 7.2 inches at 75% of that width. You can read these numbers as a direct geometry map: the width comes from the 245 mm section, while the sidewall height reflects the 75 aspect ratio. Because this tire is built for a 17-inch wheel, the diameter of the wheel sets the mounting standard, not the outside size. You should also check rim width, since the approved range runs from 6.5 to 8.0 inches. Stay inside that range, and you’ll preserve proper bead seating, load support, and handling stability. The tire’s total diameter lands near 31.5 inches, but its width and sidewall height are the key dimensions you manage when choosing fitment. For you, that means less guesswork and more control over your setup. Additionally, choosing all-terrain tires can enhance your vehicle’s performance across various terrains.

What Tire Pressure Works Best for 245/75R17?

You can start with 30 to 35 PSI for a 245/75R17 tire, then adjust it based on load, driving conditions, and the vehicle’s owner manual. A chalk test lets you verify whether the tread is contacting the road evenly, which helps you fine-tune pressure for your specific use. For highway driving, towing, or off-road use, you’ll often need different pressures to balance traction, ride quality, and tire wear. Additionally, low rolling resistance tires can further enhance fuel efficiency, making them a great choice for the Toyota RAV4.

Chalk Test Method

The chalk test method gives you a practical way to verify whether a 245/75R17 tire is inflated correctly: mark the tread with chalk, drive a short distance, and inspect how evenly the chalk wears away. Use it to tune tire pressure toward the manufacturer’s 30-35 PSI range and detect uneven wear before it compounds.

1. Apply chalk across the tread shoulders and center.
2. Drive straight on a clean surface for a short distance.
3. Examine the wear pattern: even removal suggests balanced inflation.
4. Adjust PSI in small steps, then retest.

When the chalk disappears uniformly, you’ve likely found a functional pressure setting. If the center wipes first, you’re probably overinflated; if the shoulders clear first, you’re likely underinflated. Regular checks keep you driving with control, efficiency, and less tire waste.

Pressure By Use

For most 245/75R17 tires, the best working pressure falls in the 30–35 PSI range, but the correct setting depends on your vehicle’s door-jamb placard, load, and driving conditions. You should treat that number as a starting point, not a command. When your tire pressure matches the placard, you get better fuel economy, steadier handling, and longer tread life. Because these tires have a diameter suited to trucks and SUVs, small PSI changes can alter response and wear. If you run underinflated, you’ll scrub the outer shoulders and waste energy; if you overinflate, you’ll stiffen the ride and raise blowout risk. Check pressure monthly and before trips, and adjust it to your load and driving habits for the most efficient, liberated performance.
