9.5/24.5-13 Tire Size Guide

The 9.5/24.5-13 size uses a specialty numeric racing format. In this code, 9.5 refers to the nominal section width in inches, 24.5 refers to the tire's overall outside diameter in inches, and 13 is the wheel diameter the tire fits.

Unlike a modern P-metric size, the 9.5/24.5-13 format does not spell out an aspect ratio or use millimeters for width. It is aimed more at buyers comparing tire height, wheel fit, and racing proportions directly. That makes it especially useful when rollout, gearing effect, sidewall profile, and body clearance matter more than the everyday replacement logic used with standard passenger-car tire sizing.

The 9.5/24.5-13 tire fits a 13-inch wheel, which is 330.2 millimeters at the bead seat. The wheel diameter must match exactly, because tire beads are designed for one specific rim diameter only.

Wheel width matters too. In this size, the listed fitment uses an 8-inch rim, so buyers should confirm that their actual wheel matches the tire's intended profile rather than assuming any 13-inch wheel will work. A correct diameter with the wrong width can change sidewall shape, footprint, and clearance, all of which are especially important when a car is being set up for predictable launch and repeatable track behavior.

The 9.5/24.5-13 tire has a nominal section width of 9.5 inches. Section width measures the tire at its widest point from sidewall to sidewall, not across the tread face that contacts the ground.

Clearance checks should be based on section width because sidewall bulge is often what reaches the nearest obstacle first. Tread width may be narrower than the stated section width, so a buyer who only compares tread numbers can miss a fitment problem. On a racing or specialty application, section width should be checked against wheel tubs, springs, shocks, and outer bodywork before treating the size as interchangeable with another tire that appears similar at first glance.

Yes, 9524513 is simply a condensed way of writing the 9.5/24.5-13 size. The measurements it represents stay the same: 9.5-inch nominal width, 24.5-inch overall diameter, and 13-inch wheel diameter.

Buyers often run into spacing and punctuation differences in older catalogs, racing references, and search results. What matters is that the underlying size values match, not whether the code uses slashes, dashes, or compressed numbering. Even so, a matching shorthand size should not replace normal fitment checks. Wheel width, actual tire construction, and intended use still need to line up with the vehicle and the specific wheel being used.

The 9.5/24.5-13 is commonly a tube-type fitment. Even so, tube use is ultimately a wheel-and-tire-system question rather than a size question, so the final decision should be confirmed against the actual wheel and tire being used.

Drag and specialty sizes often get installed on wheels with very specific bead-seat designs, surface conditions, and intended uses, which is why the answer should never stop with the size code alone. Wheel construction, tire design, and manufacturer guidance all matter. Before mounting the 9.5/24.5-13, buyers should check the wheel's condition, make sure the rim is appropriate for the tire, and verify whether a tube is recommended for the exact combination on the car.

The 9.5/24.5-13 tire weighs 15 pounds in the currently listed version. Tire weight is measured without the wheel, so it reflects only the tire itself rather than the full mounted assembly.

Weight matters because it contributes to unsprung mass and can influence how quickly the driveline and suspension respond. In a racing application, even modest weight differences can affect how a car leaves the line or reacts to setup changes. Buyers comparing similar specialty sizes should look at weight alongside overall diameter, section width, and construction type rather than treating weight alone as the deciding factor.

The 9.5/24.5-13 is best understood as a drag racing, competition, or specialty-use size rather than a general passenger-car replacement size. Its format and bias-ply construction point toward purpose-built applications where launch behavior, overall tire height, and track setup are central concerns.

A buyer should treat this size as a fitment that belongs on a vehicle already configured around it, not as a casual substitute for a regular street tire. Wheel diameter, wheel width, suspension travel, and body clearance all need to be checked in context. If the car is being built around a particular rollout or stance, compare this size with your current tire height and wheel setup before assuming it will deliver the same package.

No, a matching 13-inch diameter alone does not make every wheel suitable for the 9.5/24.5-13. This size is associated with an 8.00-inch rim width, and that wheel width helps establish the tire's intended profile and footprint.

Diameter gets the bead seated, but width controls how the sidewall stands and how the tire presents itself under load. A wheel that differs too far from the intended width can alter bulge, tread shape, and clearance around the car. On a specialty or competition setup, those changes can affect consistency as much as appearance, so buyers should verify both the 13-inch diameter and the 8.00-inch width before treating the combination as correct.

The smartest way to check 9.5/24.5-13 fitment is to verify wheel diameter first, then compare wheel width, section width, and overall tire height against the actual car. Because this is a specialty size, clearance should be checked at the sidewall, outer body, suspension, and any nearby chassis components.

Measure the existing setup with the car at normal ride height and consider how the tire will behave under acceleration and suspension movement. Bias-ply construction can react differently than a street radial, so static measurements alone may not tell the whole story. If the car is intended for judged originality or a period racing presentation, construction style and overall proportion also matter alongside pure physical fit.

The 9.5/24.5-13 uses bias-ply construction, which typically gives a different feel than a modern radial. Buyers can expect more sidewall movement and a more traditional specialty-tire character, especially in a drag-oriented application where straight-line behavior matters more than everyday cornering refinement.

Driving feel depends on more than construction alone. Suspension geometry, alignment, vehicle weight, tire age, and wheel width all influence how the car responds. On a purpose-built setup, the point of this size is usually not crisp street handling but repeatable behavior in its intended environment. Anyone moving from a regular radial street tire into a bias-ply specialty tire should expect the car to communicate differently through the steering and chassis.

The 9.5/24.5-13 is more closely associated with drag racing and specialty use than with normal daily road service. Its format, construction, and product type place it in a category where buyers usually prioritize competition-oriented sizing and behavior over broad everyday-road versatility.

Street use decisions should be made carefully and with attention to the exact tire's sidewall markings, condition, and intended purpose. A tire built around track-focused expectations may behave very differently from a standard passenger tire in braking, steering response, ride quality, and wet-road manners. Before using this size on public roads, compare the vehicle's needs, the wheel setup, and the tire's intended role rather than assuming all 13-inch bias-ply tires behave the same way.

The 24.5-inch overall height is one of the key numbers in the 9.5/24.5-13 size because it affects more than appearance. Tire height can influence gearing feel, wheel-opening fill, ride height, and the way the car transfers weight under acceleration.

A shorter or taller substitute can change how the vehicle leaves the line and how much clearance remains at the fender or chassis. On a specialty setup, that can be the difference between a combination that works cleanly and one that rubs or alters the car's behavior. Buyers comparing nearby sizes should treat overall height as a primary setup variable, not just a cosmetic detail.

The 9.5/24.5-13 size is available from M&H Racemaster. In this size, the current offering is a bias-ply drag slick, which places the focus on specialty use rather than on broad passenger-car replacement duty.

Brand choice in a niche size like this is only part of the decision. Buyers should also look closely at construction type, actual dimensions, wheel-width compatibility, and whether the tire's intended use matches the car's role. A specialty racing size needs to be judged by how well it suits the whole setup, not just by whether the brand name is familiar.

A quality 9.5/24.5-13 tire starts with the right construction, consistent sizing, and compatibility with the wheel it will be mounted on. In this type of specialty fitment, buyers should pay close attention to overall tire height, section width, and whether the tire is built for the same kind of use the vehicle will actually see.

Good selection also means thinking in complete-system terms. The wheel should be the correct 13-inch diameter and the proper width, the tire should suit the intended driving environment, and the full set should be matched where consistency matters. For a car with collector or period-racing goals, the traditional bias-ply format may also be part of what defines the correct look and feel.

Yes, sidewall style can matter, especially on a specialty or competition build where appearance is part of the overall presentation. The current 9.5/24.5-13 offering uses a blackwall sidewall, which aligns with the straightforward look many racing-oriented setups aim for.

Appearance should still come after fit and function. Buyers should choose sidewall style only after confirming wheel compatibility, construction type, and the size's actual role on the vehicle. On a drag-oriented build, the clean blackwall look often suits the period and purpose, but the more important point is that the tire's dimensions and intended use match the car's suspension, body clearance, and track plan.

The 9.5/24.5-13 should be inspected before and after use for cuts, cracking, bulges, punctures, air loss, and any uneven wear around the tread and sidewall. Because this is a specialty bias-ply size, buyers should also pay close attention to bead area condition and any signs that the tire has shifted or been stressed on the wheel.

Inspection matters even when tread looks good. Competition-oriented tires can age from time, heat cycles, storage conditions, and inactivity as well as from mileage. Before the next outing, confirm that the wheel is clean and in good condition, check valve hardware, and make sure the tire still suits the intended use. If anything about the casing or sidewall looks questionable, have the assembly evaluated before continued service.

The 9.5/24.5-13 can age out before it wears out, especially if the vehicle sees occasional use. Low mileage does not prevent rubber from hardening or sidewalls from developing age-related issues over time.

Storage conditions have a major effect on longevity. Keep the tire away from direct sunlight, excess heat, moisture, and ozone sources such as electric motors or battery chargers. A specialty bias-ply tire that spends long periods parked should still be inspected regularly and evaluated on condition, not just tread depth. Buyers should view age, storage history, and visible condition as equally important parts of replacement timing.

The 9.5/24.5-13 is commonly a tube-type fitment, but the final answer depends on the exact wheel and tire combination. Tube use should be confirmed against the actual wheel design, tire construction, and manufacturer guidance before installation.

A size code can suggest the common setup, yet it does not override the requirements of the specific components in front of you. Wheel condition, bead-seat design, and the intended use of the car can all influence the correct approach. If there is any doubt, inspect the wheel carefully and consult a qualified tire professional before mounting or reusing the assembly.

The 9.5/24.5-13 should be replaced when inspection shows cracking, bulges, cuts, persistent air loss, impact damage, or other signs that the casing is no longer trustworthy. Age also matters, even when a specialty tire still shows usable tread.

Replacement timing should be based on condition, intended use, and storage history rather than on tread depth alone. A bias-ply specialty tire can deteriorate from time, heat, and inactivity in ways that are not obvious at a quick glance. Before any event or longer drive, inspect the tire closely and have it checked professionally if there is any question about structural integrity or continued roadworthiness.

Street-use legality for the 9.5/24.5-13 should be confirmed from the tire's current sidewall markings and the requirements that apply where the vehicle will be driven. A specialty drag-oriented tire should never be assumed to meet the same expectations as a regular street replacement tire.

Rules can vary by state, event type, inspection practice, and intended road use, so buyers should review the markings on the actual tire and compare them with local requirements. Construction type and competition focus are part of that evaluation, but they are not the only factors. If the car will see public-road use, confirm the exact tire's suitability before relying on size alone.

Before using the 9.5/24.5-13 at speed or over any meaningful distance, buyers should verify tire condition, wheel compatibility, air retention, and the intended use of the exact tire being mounted. The 13-inch rim diameter and 8.00-inch wheel width should both be confirmed as part of that check.

Specialty tires deserve a more careful pre-run inspection than a casual visual glance. Check for age-related cracking, damage from storage, bead-seat concerns, and any sign that the tire and wheel combination is not appropriate. Tube setup should also be confirmed from the actual assembly. If the vehicle's use has changed from track-focused duty to broader road use, reevaluate the tire choice before proceeding.
