245/65R17 Tire Size Guide

The 245/65R17 size code identifies a metric tire with a 245-millimeter section width, a 65 aspect ratio, radial construction, and a 17-inch wheel diameter. In practical terms, the sidewall height is 65 percent of 245 mm, which comes out to about 159.25 mm or 6.27 inches per side.

Unlike an older numeric or alphanumeric size, 245/65R17 gives you the width, profile, construction type, and wheel diameter directly in the code. It does not automatically tell you tread pattern, load capacity, sidewall style, or exact approved wheel width, so those details still need to be checked on the actual tire and wheel combination being used.

The 245/65R17 fits a 17-inch wheel, which equals 431.8 millimeters at the bead seat. That rim diameter must match exactly, because a tire built for a 17-inch wheel will not seat correctly on a wheel of any other diameter.

Wheel width matters too. In this size, the available fitment range is 7.00 to 8.00 inches wide, which affects how the sidewall stands and how the tread sits on the road. A wheel outside that range can change the tire's profile and may create clearance or wear issues, so buyers should verify both wheel diameter and wheel width before installation.

The 245/65R17 has a section width of 245 millimeters, which converts to about 9.65 inches. Section width is measured at the tire's widest point from sidewall to sidewall when inflated, not across the tread face itself.

Clearance checks should be based on section width rather than tread width, because the sidewall bulge is often what reaches closest to suspension arms, inner liners, and fender edges. Wheel width also influences the tire's final mounted shape, so a 245/65R17 on a 7-inch wheel can present slightly differently than the same size on an 8-inch wheel.

The 245/65R17 has an overall diameter of 29.54 inches, or about 750.32 millimeters. That number represents the tire's full mounted and inflated height from the ground to the top of the tread, measured through the center.

Overall diameter is one of the most important figures to compare when replacing or substituting tire sizes. It affects ride height, wheel-opening fill, and speedometer behavior, and even a modest change can alter the vehicle's stance. Buyers comparing alternatives should look at diameter first, then width, wheel size, and available clearance at both the front and rear.

The 245/65R17 has a sidewall height of about 6.27 inches, which is 159.25 millimeters. That measurement runs from the wheel's bead seat to the outer edge of the tread on one side of the tire.

Sidewall height has a big influence on ride character and appearance. A taller sidewall usually adds more visual depth between the wheel and tread, and it can contribute to a more compliant feel over broken pavement. Buyers trying to preserve original proportions or avoid a too-short look in the wheel opening should pay close attention to sidewall height when comparing sizes.

The 245/65R17 turns about 682.8 revolutions per mile. That figure is tied to the tire's circumference, which in this size is about 92.8 inches around the tread surface.

Revolutions per mile matter whenever you compare one size to another. A tire that turns more times per mile is effectively smaller overall, while one that turns fewer times per mile is effectively taller. Differences here can influence speedometer and odometer readings, so it is a useful checkpoint when choosing a replacement size that is close, but not identical, to 245/65R17.

The 245/65R17 is primarily a modern radial replacement size associated with 2000s through 2020s passenger-oriented SUV and utility applications. It is not an early-era collector format, so most buyers encounter it in regular service rather than in a factory-style vintage restoration context.

If you are replacing an existing 245/65R17, start by confirming that the current size is actually correct for the vehicle and trim. Door-jamb labeling, owner's literature, wheel size, and load requirements all deserve a look, especially on SUVs and truck-based vehicles that may have towing packages, alternate wheel options, or prior owner changes.

The 245/65R17 fits wheels from 7.00 to 8.00 inches wide in the available fitment example for this size. Staying within that range helps the tire maintain its intended section shape and keeps the tread from being pinched or stretched.

A 7-inch wheel tends to hold the sidewall slightly rounder, while an 8-inch wheel can spread the casing a bit flatter. Neither is automatically wrong within the approved range, but the final look and clearance can change. Buyers should measure available space at the fender, inner wheelhouse, and suspension before assuming any same-diameter wheel will behave the same.

The 245/65R17 can be a sensible radial choice for drivability on newer builds and later vehicles, but a judged restoration may require closer comparison with the vehicle's original specifications. Construction type, size code style, and sidewall presentation all matter when authenticity is being evaluated.

For a vehicle that is being restored to factory delivery standards, buyers should compare the original documentation against the current wheel and tire package rather than relying on visual similarity alone. On the other hand, if road use and day-to-day manners matter more than concours accuracy, a modern radial in this size can make practical sense when wheel width, load needs, and clearance all check out.

The 245/65R17 combines radial construction with a 65-series sidewall, which generally gives it a balanced character for everyday use. With about 6.27 inches of sidewall, it retains enough height to avoid an overly harsh look or feel while still fitting a larger 17-inch wheel.

Ride quality depends on more than the size alone. Suspension condition, wheel width, inflation practice, vehicle weight, and tire construction details all influence how the vehicle feels over expansion joints, patched pavement, and rough secondary roads. Buyers looking for comfort should view the size as one part of the system, not the whole answer.

A radial 245/65R17 typically aims for stable, predictable road behavior rather than the tall, wandering feel some older formats can have. Its width and moderate profile tend to suit modern SUV and crossover use where drivers want a tire that feels planted without dropping into a very low-profile category.

Actual steering feel still varies with tread design, wheel width, alignment settings, and the condition of steering and suspension parts. On a worn chassis, even the correct size can feel vague or uneven. Buyers replacing a full set should also keep construction and service category consistent across the vehicle so front-to-rear behavior stays more uniform.

The 245/65R17 is a modern radial size commonly used on vehicles that see regular highway travel, but road behavior depends on the exact tire, its load rating, speed rating, age, and condition. The example in this size carries an S speed rating, so buyers should verify the actual sidewall markings on the tire they intend to run.

Long-distance use also places more demand on inflation accuracy, alignment, and heat management than short local trips. Before interstate travel, inspect the tires for cracking, impact damage, uneven wear, and air loss, and make sure the chosen tire matches the vehicle's real service demands. Size alone does not guarantee that every 245/65R17 will be appropriate for every trip.

BFGoodrich is available in the 245/65R17 size. Even when only one brand is in view, buyers should still look beyond the size code and confirm the tire's intended service category, sidewall presentation, and load capability against the vehicle's actual use.

Brand choice matters most when it aligns with the job the vehicle has to do. A daily-driven crossover, a truck-based SUV, and a utility vehicle used for heavier service can share the same size while needing different priorities. Construction consistency across the full set, proper wheel fit, and correct load matching matter more than choosing by name alone.

Quality in the 245/65R17 size starts with the basics: correct dimensions, proper wheel fit, suitable load capacity, and construction that matches the vehicle's use. A tire can be well made and still be the wrong choice if its service category or sidewall style does not suit the job.

Look at the full package rather than any single feature. Check the speed rating shown on the sidewall, compare the approved wheel width range to your actual wheel, and make sure all four tires are matched in size and construction. For buyers balancing appearance with real-world use, consistent fitment and predictable behavior are stronger indicators of a good choice than marketing language.

Yes, sidewall style can matter if you care about appearance as well as fitment. The available 245/65R17 example uses raised white letter styling, which gives the tire a more assertive truck and SUV look than a plain black sidewall.

Visual choice should stay secondary to proper specification. Raised white letter tires may suit a more rugged build theme, while some owners prefer a quieter appearance that lets the wheel or body style stand out instead. Either way, sidewall appearance should be considered only after wheel width, load requirement, and intended road use have been confirmed.

A 245/65R17 can age out before it wears out, especially if it spends long periods parked or sees wide temperature swings. Time, heat, sunlight, ozone exposure, and underuse all affect the casing and sidewall, so tread depth alone is not enough to judge remaining service life.

Regular inspections are the best habit here. Check for cracking, bulges, punctures, vibration changes, and uneven wear, and review the tire's age and overall condition before long trips. Even on a vehicle in regular use, replacement timing should be based on condition, service demands, and current sidewall markings rather than mileage alone.

For a regularly driven 245/65R17, the biggest maintenance priorities are inflation checks, visual inspection, and watching for uneven wear. A tire in this size is often used on heavier passenger vehicles and utility platforms, so small alignment or pressure issues can show up as shoulder wear, feathering, or steering changes fairly quickly.

Use the vehicle manufacturer's recommendations as the starting point, then inspect the tread and sidewalls on a routine schedule. If you notice repeated air loss, pull, cupping, or rapid edge wear, the issue may be wheel alignment, suspension wear, or wheel damage rather than the size itself. Catching those problems early helps preserve tire life and road manners.

The 245/65R17 is normally a tubeless fitment. Even so, tube use is a wheel-and-tire-system question rather than a size question, so the final decision should be confirmed against the actual wheel and the specific tire being used.

Most buyers in this size will be working with modern one-piece tubeless wheels, but wheel condition still matters. Damaged bead seats, corrosion, or unusual wheel designs can change what is appropriate. If there is any doubt about wheel integrity or the correct mounting method, have the assembly evaluated by a qualified tire professional before putting it into service.

The 245/65R17 should be replaced when inspection shows cracking, bulges, impact damage, exposed cords, repeated air loss, or wear severe enough to compromise wet-road traction and general roadworthiness. Tire age also matters, even if the tread still looks usable at a glance.

Condition-based replacement is especially important on vehicles that carry families, cargo, or trailer weight. Before road trips, inspect all four tires and the spare, and pay attention to vibration or pull that develops suddenly. Buyers should treat visible damage or age-related deterioration as a service issue, not just a cosmetic one.

Load and speed details should always be verified on the actual tire, not assumed from the size alone. The available 245/65R17 example is rated at 2,405 pounds at 65 psi and shows an S speed rating in the sidewall marking, but other tires in the same size may differ.

Matching those figures to the vehicle's real use is critical on SUVs and utility vehicles. Passenger count, cargo, towing demands, and wheel choice can all influence what is appropriate. Buyers should compare the tire's sidewall markings to the vehicle's requirements and avoid mixing tires with meaningfully different service characteristics on the same vehicle.

No buyer should assume that every 245/65R17 is automatically street legal everywhere or interchangeable across every application. The size tells you width, profile, construction, and rim diameter, but legality and suitability also depend on the exact tire's markings, service category, condition, and the vehicle it is installed on.

Review current sidewall markings, local requirements, and the vehicle manufacturer's specifications before use on public roads. Interchangeability is also limited by wheel width, load capacity, and clearance, not just by matching the size code. When the vehicle's use includes highway travel, towing, or heavy passenger loads, a qualified tire professional can help confirm that the full combination is appropriate.
