Jeep Trucks Wrangler JK Tires
Jeep Trucks Wrangler JK represents the final chapter of the JK-generation Wrangler, a modern off-road 4x4 that carried forward the classic Jeep formula of short overhangs, removable top configurations, and serious trail intent. By 2018, Wrangler JK models could vary noticeably in wheel and tire package depending on trim, option group, and intended use, so tire selection is not as simple as choosing by model name alone. The key complication here is that 2018 Jeep Trucks Wrangler JK appears with multiple tire sizes and three different rim diameters. Before choosing a tire, first confirm whether the Jeep Trucks Wrangler JK in your garage is on 16-inch, 17-inch, or 18-inch wheels.
Jeep Trucks Wrangler JK Tire Size Guide
Jeep Trucks Wrangler JK uses 6 distinct tire sizes across the 2018 model year, and the most important fitment fact is that these sizes span 16-inch, 17-inch, and 18-inch rim diameters. Every size shown here uses a metric radial format, so the section width is given in millimeters, the second number is the aspect ratio, and the final number is the wheel diameter in inches. That means the correct choice comes down to matching the exact wheel size and the specific tire package fitted to the Jeep Trucks Wrangler JK.
255/70R18 fits 2018 Jeep Trucks Wrangler JK applications that use an 18-inch wheel package. In this code, 255 is the section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 18 is the rim diameter in inches. Choose this size only if the Jeep Trucks Wrangler JK is actually equipped with 18-inch wheels, since no interchangeable 16-inch or 17-inch fitment should be assumed.
245/75R17 fits 2018 Jeep Trucks Wrangler JK and corresponds to the available BFGoodrich radial product built for a 17-inch rim. In this code, 245 is the section width in millimeters, 75 is the aspect ratio, R marks radial construction, and the product uses a 17-inch rim diameter. Choose this size when the Jeep Trucks Wrangler JK carries the narrower 17-inch package rather than one of the 16-inch, 18-inch, or wider 17-inch alternatives.
255/75R17 fits certain 2018 Jeep Trucks Wrangler JK configurations using 17-inch wheels. In this code, 255 is the section width in millimeters, 75 is the aspect ratio, R indicates radial construction, and 17 is the rim diameter in inches. Choose this size only after matching the sidewall marking on the existing tire or the original vehicle tire placard, since 2018 Jeep Trucks Wrangler JK also uses other 17-inch sizes.
225/75R16 fits 2018 Jeep Trucks Wrangler JK applications equipped with the smaller 16-inch wheel package, and an available BFGoodrich radial product is listed for it. In this code, 225 is the section width in millimeters, 75 is the aspect ratio, R means radial construction, and the product is built for a 16-inch rim diameter. Choose this size when the Jeep Trucks Wrangler JK is on 16-inch wheels and needs the narrower of the two listed 16-inch fitments.
245/75R16 fits 2018 Jeep Trucks Wrangler JK and matches an available BFGoodrich radial tire for a 16-inch wheel. In this code, 245 is the section width in millimeters, 75 is the aspect ratio, R denotes radial construction, and the product uses a 16-inch rim diameter. Choose this size when the Jeep Trucks Wrangler JK has 16-inch wheels but requires the wider 245-section fitment instead of 225/75R16.
265/70R17 fits 2018 Jeep Trucks Wrangler JK and has two available BFGoodrich radial products built for 17-inch rims. In this code, 265 is the section width in millimeters, 70 is the aspect ratio, R marks radial construction, and the products use a 17-inch rim diameter. Choose this size when the Jeep Trucks Wrangler JK carries the wider 17-inch package, and verify the required load rating because two versions are listed in the same size.
Because 2018 lists six different sizes across 16-inch, 17-inch, and 18-inch wheels, identify the specific wheel diameter and tire package on the Jeep Trucks Wrangler JK before selecting a tire.

Frequently Asked Questions
The FAQ below focuses on the real fitment questions that come up with 2018 Jeep Trucks Wrangler JK models, especially the multiple wheel diameters, the six listed size choices, and the available radial all-terrain products in select sizes.
Size Basics & Fitment
Jeep Trucks Wrangler JK uses six tire sizes in 2018: 225/75R16, 245/75R16, 245/75R17, 255/75R17, 265/70R17, and 255/70R18. Those sizes span three wheel diameters, with 16-inch fitments in 225/75R16 and 245/75R16, 17-inch fitments in 245/75R17, 255/75R17, and 265/70R17, and an 18-inch fitment in 255/70R18.
That spread means model year alone is not enough to identify the correct tire for a Jeep Trucks Wrangler JK. Start by checking the sidewall of the current tire, the vehicle placard, and the actual wheel diameter, then match the exact size rather than choosing only by make and model.
2018 Jeep Trucks Wrangler JK has six tire sizes listed because the model year includes multiple wheel and tire packages rather than one universal setup. The split is primarily a rim-diameter split, with 16-inch, 17-inch, and 18-inch wheels all appearing in the same year, and there are also multiple width and aspect-ratio combinations within the 17-inch group.
A Jeep Trucks Wrangler JK owner should treat the model year as a starting point, not a final fitment answer. The practical step is to identify the specific wheel package on the vehicle first, then match the exact sidewall size so the replacement tire stays consistent with the intended wheel diameter and proportions.
Jeep Trucks Wrangler JK uses three rim diameters in the 2018 listings: 16 inches, 17 inches, and 18 inches. The 16-inch group includes 225/75R16 and 245/75R16, the 17-inch group includes 245/75R17, 255/75R17, and 265/70R17, and the 18-inch group includes 255/70R18.
Wheel diameter is the first item to verify because a 16-inch, 17-inch, or 18-inch tire is not interchangeable across different wheels. Measuring the wheel or reading the current tire sidewall will resolve that quickly, and only after that should a Jeep Trucks Wrangler JK owner compare width, aspect ratio, and load version.
Buying the Right Tire
The correct tire size for a 2018 Jeep Trucks Wrangler JK is the one that matches the wheel diameter and the exact sidewall size fitted to that specific Jeep. The year can point you to the six possible sizes, but it does not narrow the vehicle to one fitment because 16-inch, 17-inch, and 18-inch packages were all used.
A careful check should include the sidewall marking on the current tire, the wheel diameter itself, and the vehicle tire placard if still present. That process is especially important on Jeep Trucks Wrangler JK models that may have had wheel changes during their service life, because a non-original wheel can change the correct replacement size.
The available Jeep Trucks Wrangler JK products here use RWL sidewalls, meaning raised white letters. Every listed BFGoodrich product in the available 16-inch and 17-inch sizes carries that same sidewall style, so there is no blackwall or alternative sidewall treatment within the current product group.
Sidewall appearance matters on a Jeep Trucks Wrangler JK because it can change the visual character of the vehicle even when the size stays correct. If the goal is to keep a matching look, compare the new tire’s sidewall style with the existing set so the replacement does not stand out from the rest of the vehicle.
BFGoodrich is the listed brand for the available Jeep Trucks Wrangler JK products here. The current product group centers on the All-Terrain T/A KO2 series, with available fitments in 225/75R16, 245/75R16, 245/75R17, and 265/70R17, including two load versions in the 265/70R17 size.
Brand alone does not establish correct fitment for a Jeep Trucks Wrangler JK, because the key match points are the exact size, wheel diameter, and the load version where more than one product exists in the same size. Once those basics are confirmed, brand and sidewall preference become easier choices.
The listed Jeep Trucks Wrangler JK products are all part of one series: BFGoodrich All-Terrain T/A KO2. Within that series, the main differences shown are size, compatible rim-width range, and load version, as seen in the two 265/70R17 products that share the same nominal size but carry different load capacities and inflation ratings.
That means a Jeep Trucks Wrangler JK owner is choosing within a single all-terrain family rather than comparing multiple construction approaches or period-style series. The practical decision is to match the wheel diameter and sidewall size first, then check whether the listed load version suits the way the vehicle is equipped and used.
Maintenance & Longevity
A stored Jeep Trucks Wrangler JK should be kept on clean, properly inflated tires in a cool, dry, and dark environment away from direct sunlight, ozone sources, and petroleum contamination. If the vehicle will sit for extended periods, moving it occasionally or supporting it to reduce prolonged flat spotting can help preserve tire shape.
Collector-style storage habits still matter even on modern radial tires because low-use vehicles often age their tires long before they wear them out. Keeping a Jeep Trucks Wrangler JK out of weather, checking inflation regularly, and avoiding long stationary periods on one contact patch will help maintain ride quality and casing condition.
Tires on a Jeep Trucks Wrangler JK should be inspected regularly, with a visual check before driving and a more careful inspection at routine service intervals. That inspection should include tread depth, air pressure, irregular wear, cuts, sidewall cracking, punctures, and any impact damage from off-road or curb contact.
Frequent inspection is especially important on Jeep Trucks Wrangler JK because all-terrain use can expose the tires to rocks, debris, and sidewall hazards that do not always show up as immediate air loss. Catching uneven wear early can also reveal alignment, suspension, or inflation issues before they shorten tire life.
Tires on a Jeep Trucks Wrangler JK should be replaced when age, cracking, impact damage, sidewall injury, repeated air loss, or structural concerns appear, even if tread depth still looks acceptable. Low-mileage vehicles often reach the end of safe tire service because of time and environmental exposure rather than worn-out tread.
A Jeep Trucks Wrangler JK owner should think of tread depth as only one part of the decision. If the tires are aging out, have hardened noticeably, or show visible weathering, replacement is the prudent move even when the vehicle is driven only occasionally or the tread still appears serviceable.
Restoration & Authenticity
Jeep Trucks Wrangler JK appears with multiple original-type size possibilities for 2018 rather than one single tire size across the full model year. The listed sizes are 225/75R16, 245/75R16, 245/75R17, 255/75R17, 265/70R17, and 255/70R18, which indicates different wheel and tire packages depending on the specific vehicle configuration.
For an authenticity-minded Jeep Trucks Wrangler JK owner, the most reliable approach is to verify the exact size from the original vehicle placard, factory paperwork, or surviving take-off tires if those are known to be original to the vehicle. That matters more here than relying on model year alone because several factory-style combinations existed.
Correct tire fitment can affect how a Jeep Trucks Wrangler JK is judged or valued, especially when the vehicle is being presented as an unmodified example. Size, sidewall appearance, and wheel-diameter correctness all shape whether the vehicle looks consistent with its original configuration and trim-level character.
A Jeep Trucks Wrangler JK built for preservation generally benefits from staying with the proper wheel diameter and matching sidewall style rather than mixing unrelated aftermarket combinations. Owners concerned with marque accuracy should compare the vehicle against factory references or enthusiast club standards before making a change that alters stance or appearance.
The listed Jeep Trucks Wrangler JK products use RWL, or raised white letter, sidewalls. Since every available product in the current group shares that style, RWL is the visible sidewall treatment represented here for the applicable 16-inch and 17-inch sizes.
For a restoration-minded Jeep Trucks Wrangler JK owner, sidewall style should be matched to the vehicle’s original wheel-and-tire package rather than chosen only by taste. If the Jeep is being returned to a specific trim appearance, compare the current sidewall style to period photos, original sales material, or the surviving tire setup on the vehicle.
Safety & Road Use
The listed Jeep Trucks Wrangler JK products are modern radial tires intended for road use when they are installed in the correct size on the correct wheel and are maintained in proper condition. Safety depends on matching the exact rim diameter, using an appropriate load version, and ensuring the tire is in sound condition with correct inflation.
A Jeep Trucks Wrangler JK owner should avoid assuming that any listed size is interchangeable simply because it appears under the same model year. Public-road use is reasonable only after confirming the vehicle’s actual wheel package, checking for damage or age-related deterioration, and making sure the tires are suited to the vehicle’s present configuration.
Before driving a Jeep Trucks Wrangler JK, check tire pressure, visible sidewall condition, tread condition, and whether all four tires match in size and general type. On the available 265/70R17 fitment, it is also wise to confirm which load version is installed, since two products in that same size carry different load capacities.
That quick inspection helps catch the kinds of issues that matter most on a Jeep Trucks Wrangler JK used for mixed road and trail duty. Uneven inflation, a mismatched replacement tire, or unnoticed sidewall damage can affect handling and durability well before the problem becomes obvious from the driver’s seat.
A Jeep Trucks Wrangler JK should always be driven at speeds appropriate to the exact tire installed, its load rating, its inflation, and its overall condition. The listed products include speed-rated radial tires, but safe operating speed is never determined by the model name alone because size, load version, wear, and service condition all matter.
The practical rule for a Jeep Trucks Wrangler JK is to stay within the limits of the specific tire and to reduce speed when the vehicle is heavily loaded, driven off pavement, or running on older tires. Tire condition and proper inflation are just as important as the size itself when judging road-speed suitability.
