245/70R16 Tire Size Guide

The 245/70R16 designation breaks down into four parts. The 245 is the tire's section width in millimeters, the 70 is the aspect ratio, meaning the sidewall height equals 70 percent of the width, the R means radial construction, and the 16 is the wheel diameter in inches. For this size, the sidewall height works out to 6.75 inches and the overall diameter is 29.5 inches.

Unlike older alphanumeric or numeric sizes, 245/70R16 gives you both width and profile directly in the code. What it does not tell you by itself is the exact load capacity, speed category, sidewall style, or approved wheel-width range for a specific tire. Those details still need to be checked on the actual sidewall and against the wheel and vehicle being used.

The 245/70R16 fits a 16-inch wheel, which is 406.4 millimeters in diameter. The wheel diameter must match exactly because the bead seat diameter is fixed; a 245/70R16 cannot be mounted on a 15-inch or 17-inch rim.

Wheel width matters too, not just wheel diameter. In this size, the supported rim width shown here is 6.50 to 7.00 inches, which affects how the tire's profile sits and how close the sidewall may run to suspension or body components. If your wheel falls outside that range, the tire can change shape enough to affect clearance, wear behavior, and steering response.

The 245/70R16 has a section width of 245 millimeters, which is about 9.65 inches. Section width measures the tire at its widest inflated point from sidewall to sidewall rather than across the tread face.

Tread width is usually narrower than section width, so section width is the more important number when checking fitment. Fender lips, inner wheelhouses, suspension links, and steering components all care about the tire's widest point. On vehicles with tight front-end packaging or limited turning clearance, even small differences in section width can matter more than buyers expect.

The 245/70R16 has an overall diameter of 29.5 inches, or about 749.3 millimeters. That is the full height of the mounted and inflated tire from the ground to the top, measured through the center.

Overall diameter influences more than appearance. It affects wheel-opening fill, ride height, gearing feel, and the accuracy of the speedometer and odometer. When shoppers compare the 245/70R16 with a substitute size, diameter is one of the first measurements to line up, because a change here can alter both stance and the way the vehicle feels at road speed.

The 245/70R16 has a sidewall height of 6.75 inches, which equals 171.5 millimeters. That figure comes from taking 70 percent of the 245-millimeter section width and converting it to inches.

Sidewall height has a big effect on both appearance and drivability. A taller sidewall generally adds more cushioning and gives the tire a fuller look in the wheel opening, while a shorter one usually feels firmer and more immediate in steering response. On this size, the 70-series profile keeps a substantial sidewall without moving into the very tall proportions seen on older truck sizes.

The 245/70R16 turns about 683.6 revolutions per mile. That number is based on its calculated circumference of 92.68 inches and shows how many full rotations the tire makes over one mile of travel.

Revolutions per mile are useful when comparing replacement sizes because they connect tire dimensions to how the vehicle reads speed and distance. If a substitute turns noticeably more or fewer revolutions per mile, the speedometer and odometer will no longer track the same way. Buyers comparing alternatives should look at this figure along with section width and overall diameter rather than relying on width alone.

No, the 245/70R16 should be treated as a size match, not an automatic fitment guarantee. Vehicles that use this size can differ in wheel width, offset, suspension geometry, brake-package clearance, trim level, and load requirements, even when the sidewall size looks the same.

A smart fitment check starts with the vehicle placard or factory documentation, then moves to the wheel itself and the available room around the tire. Compare the actual wheel diameter, the 6.50 to 7.00 inch rim-width range shown for this size, and clearance at full lock and full suspension movement. If the vehicle is lifted, lowered, or carrying non-stock wheels, those changes matter just as much as the size code.

Wheel width is a major part of 245/70R16 fitment. The supported rim-width range shown here is 6.50 to 7.00 inches, and moving outside that window can change the tire's profile enough to affect wear pattern, steering feel, and body or suspension clearance.

A narrow wheel pulls the sidewalls inward and can make the tire appear taller and rounder, while a wider wheel spreads the casing and can move the shoulders outward. Those shape changes affect how the tire sits under the vehicle even though the sidewall still reads 245/70R16. Buyers should match the wheel width first, then confirm that the mounted section width still clears nearby components.

The 245/70R16 is a radial replacement size first and foremost, so it is usually better suited to modern service use than to strict authenticity goals. Radial construction can improve everyday drivability, but a vehicle being judged on factory-correct appearance may call for a different size format or construction type.

Originality-minded buyers should compare the sidewall style, overall diameter, and visual proportion of the tire in the wheel opening before assuming this size matches an earlier factory look. Even when the dimensions work, a modern metric radial code can present a different appearance than older original-equipment sizing systems. For a driver-quality build, usability may matter more; for judged work, documentation should lead the decision.

The 245/70R16 generally lands in a comfortable middle range because its 70-series sidewall is tall enough to add some compliance without becoming unusually tall for a modern radial. With a 29.5-inch overall diameter and 6.75-inch sidewall, it typically balances ride softness with everyday control better than a shorter-profile replacement.

Ride quality still depends on more than size alone. Suspension condition, wheel width, inflation, load carried, and the specific tire's construction all shape the final result. On an SUV or light truck used in regular service, this size often feels more forgiving than lower-profile alternatives, but buyers should still judge it as part of the full wheel-and-tire system rather than by dimensions alone.

A 245/70R16 radial usually delivers a steadier, more familiar modern steering feel than older tall-profile vintage constructions. The 245-millimeter width gives the tire meaningful footprint, while the 70-series sidewall still leaves enough sidewall height to soften impacts and keep the response from feeling overly sharp.

Steering behavior changes with wheel width, alignment settings, and the tire's actual casing design. Mounted on a wheel within the 6.50 to 7.00 inch range, the profile should stay closer to its intended shape. If the vehicle has worn steering parts or non-stock alignment, even a correctly sized tire can feel vague or heavy, so the size should be evaluated alongside the condition of the chassis.

With an overall diameter of 29.5 inches and about 683.6 revolutions per mile, the 245/70R16 establishes the baseline for how the vehicle's gearing and speedometer behave in this size. Any substitute that changes those numbers will also change effective gearing feel and indicated road speed.

A taller alternative usually turns fewer revolutions per mile, which can make gearing feel slightly longer and leave more fill in the wheel opening. A shorter one does the opposite, often making the vehicle feel busier at speed while reducing ride height. Buyers comparing alternatives should track diameter and revolutions per mile together, because width alone does not tell the whole drivability story.

BFGoodrich is available in the 245/70R16. Even when a size is offered by only one listed brand, buyers should still compare the tire's construction details, service description, and intended use with the vehicle's real workload rather than assuming every 245/70R16 serves the same purpose.

Brand choice matters, but size-level quality decisions go beyond the name on the sidewall. Look at whether the tire's load capability, wheel-width compatibility, sidewall appearance, and use case line up with how the vehicle is actually driven. On a regularly used SUV or truck, choosing a tire that matches the vehicle's weight and road use is more important than treating the size itself as a universal answer.

A quality 245/70R16 starts with the basics being right for the vehicle: correct radial construction, the proper 16-inch rim fit, an approved wheel-width range, and a service description that matches real-world load demands. Dimensional accuracy matters too, because small shifts in width or diameter can affect clearance and speedometer behavior.

Shoppers should also pay attention to how consistently the tire matches the intended use of the vehicle. A daily-driven SUV, pickup, or utility vehicle may prioritize road manners and load support differently than a specialty build. When comparing options in the same size, keep the whole set matched so the vehicle carries the same construction type, dimensions, and response characteristics at all four corners.

Yes, sidewall style can matter more than many buyers expect because it changes the visual character of the vehicle without changing the size code. In this size, a raised white letter sidewall is one of the available looks, and that can push the tire toward a more traditional truck and SUV appearance.

Appearance should still be balanced with function. A sidewall style does not change the need to confirm wheel width, load rating, and intended use, but it does influence how appropriate the tire looks on the vehicle. Buyers trying to preserve a certain era feel or factory-like presentation should compare sidewall treatment carefully before mixing different visual styles in the same set.

A 245/70R16 on a vehicle in regular use should be inspected routinely for cuts, cracking, bulges, punctures, uneven wear, and air loss. It is also worth checking the shoulders and inner sidewall area, because wear patterns there can reveal alignment issues, underinflation, or wheel-width mismatches before the problem becomes more serious.

Regular inspection matters because radial tires can still age and degrade even when they look usable at a glance. Highway miles, curb contact, heat cycles, and seasonal temperature swings all add stress over time. Before longer trips, give the full set a close visual check and confirm that tread wear is even from side to side rather than assuming mileage alone tells the whole story.

The 245/70R16 is normally a tubeless fitment. Tube use is still a wheel-and-tire-system question rather than a size question, so the final setup should be confirmed against the actual wheel and tire being used.

Most buyers using a 16-inch modern radial size will be working with tubeless-compatible wheels, but condition and wheel design still matter. If the wheel has damage, corrosion, or an unusual construction, that can change what is appropriate. When there is any doubt, review the markings on the tire and wheel and have the combination checked by a qualified tire professional before service.

A lightly used 245/70R16 can still age out before it wears out. Time, heat, sunlight, ozone exposure, and long periods of sitting all affect the rubber and casing, even when tread depth remains respectable.

Occasional-use vehicles benefit from clean, dry storage away from direct sunlight and electric motors or equipment that generate ozone. Move the vehicle periodically, keep an eye on air retention, and inspect for flat spotting or early cracking before returning it to road use. Low annual mileage should never be treated as proof that an older tire is still ready for modern driving conditions.

The 245/70R16 should be replaced when inspection shows cracking, bulges, exposed cords, repeated air loss, impact damage, or uneven wear severe enough to suggest structural trouble. Replacement timing is not just about tread depth; age and condition matter too, especially on vehicles that see mixed city and highway use.

Before long trips, inspect all four tires closely and look at the spare if it matches the road set. A tire can have usable tread and still be a poor candidate for continued service if the rubber has hardened or the casing shows damage. Buyers should review the current sidewall markings and overall condition rather than assuming size alone answers the safety question.

Load capacity is critical on the 245/70R16 because vehicles using this size can range from lighter SUVs to trucks that regularly carry passengers, cargo, or towing-related loads. One listed example in this size is rated at 2,535 pounds at 65 psi, and that pairing should be treated as a matched load-and-pressure figure.

Buyers should compare the tire's actual service description with the vehicle's requirements before installation, especially if the vehicle is used for hauling or sustained road travel. Matching size alone is not enough when load demand changes from one application to another. If the vehicle's expected use is close to its capacity, confirm the full specification carefully before putting the tires into service.

No tire size is automatically suitable for every modern highway situation just because the dimensions match. The 245/70R16 is a modern radial size, but buyers still need to evaluate tire age, condition, load capacity, wheel compatibility, and the exact service description molded on the sidewall.

Road-readiness depends on the complete tire and wheel package, not the size code alone. Check for damage, verify the tire is mounted on the correct 16-inch wheel, and make sure the wheel width stays within the 6.50 to 7.00 inch range shown here. Local requirements and inspection expectations can also differ, so it is wise to review current markings and consult a qualified tire professional when questions remain.
