2018 Jeep Trucks Tire Fitment Guide

2018 Jeep Trucks vehicles use 20 tire sizes across six model lines: 225/55R18, 225/60R17, 225/60R18, 225/65R17, 245/65R17, 235/45R19, 215/65R16, 215/65R17, 265/50R20, 245/70R17, 265/60R18, 295/45R20, 215/60R17, 285/70R17, 245/75R17, 255/75R17, 255/70R18, 225/75R16, 245/75R16, and 265/70R17. Rim diameters span 16, 17, 18, 19, and 20 inches, and sizes are divided by model rather than shared across the entire 2018 Jeep Trucks lineup.

Cherokee, Compass, and Renegade share some crossover-style sizes, while Grand Cherokee, Wrangler, and Wrangler JK each have more specialized fitments. Rim width information is available for several sizes, including 215/65R16 at 5.50 to 7.50 inches, 225/65R17 at 6.0 to 8.0 inches, 245/65R17 at 7.0 to 8.0 inches, 245/70R17 at 6.5 to 8.0 inches, 285/70R17 at 7.5 to 9.5 inches, 245/75R17 at 6.5 to 7.5 inches, 225/75R16 at 6.0 to 7.0 inches, 245/75R16 at 6.5 to 8.0 inches, and 265/70R17 at 7.0 to 9.0 inches. Start by matching the exact model and wheel diameter already on the vehicle.

On a 2018 Jeep Trucks tire, 225/60R17 is a modern metric radial size. The 225 is the nominal section width in millimeters, 60 is the aspect ratio, R identifies radial construction, and 17 is the wheel diameter in inches. Within the 2018 Jeep Trucks range, this size appears on Cherokee and Compass applications rather than on Grand Cherokee or Wrangler-family models.

That code matters because another Jeep in the same model year may also use a 17-inch wheel while requiring a completely different section width and profile. In available products for 225/60R17, the example shown carries a 99T service description, which means a T speed rating with a 118 mph ceiling. If your Cherokee or Compass has this size on the sidewall, use that exact code as the starting point before comparing appearance or brand.

No, 2018 Jeep Trucks models do not use one common tire size. Cherokee alone uses five sizes, Compass uses five, Grand Cherokee uses four, Renegade uses four, Wrangler uses four, and Wrangler JK uses six. Some sizes overlap between related models, such as 225/55R18 across Cherokee, Compass, and Renegade or 245/75R17 across Wrangler and Wrangler JK, but many fitments stay exclusive to one model.

That means year and make are not enough to choose correctly for a 2018 Jeep Trucks application. Grand Cherokee 20-inch sizes, Compass 19-inch sizes, and Wrangler JK 16-inch sizes are all very different use cases despite sharing the Jeep name. If the badge on the tailgate says Jeep but the model and wheel package are uncertain, check the sidewall on the current tire or the factory placard before narrowing your options.

2018 Jeep Trucks tires are available with several sidewall treatments depending on size. 225/60R17 appears with a narrow whitewall, 215/65R16 is available in RBL, redline, and wide whitewall forms, 225/65R17 uses RBL, and most of the larger Jeep utility and all-terrain sizes such as 245/65R17, 245/70R17, 285/70R17, 245/75R17, 225/75R16, 245/75R16, and 265/70R17 appear with RWL sidewalls.

The practical choice depends on the look you want as much as the model you own. Whitewall, redline, and wide whitewall options create a more custom or nostalgic visual effect on compact Jeep applications, while RBL and RWL sidewalls fit the more functional all-terrain character seen on Cherokee Trailhawk-style, Grand Cherokee utility, and Wrangler-family use. Match the sidewall style to both the correct size and the personality of the vehicle rather than treating appearance as separate from fitment.

Travelstar and BFGoodrich both cover parts of the 2018 Jeep Trucks size range shown here. Travelstar appears in 225/60R17 with a narrow whitewall radial, while BFGoodrich covers 225/65R17, 245/65R17, 215/65R16, 245/70R17, 285/70R17, 245/75R17, 225/75R16, 245/75R16, and 265/70R17. Within BFGoodrich, the product mix includes All-Terrain T/A KO2 utility tires as well as Silvertown Radial options in more style-focused sidewall treatments.

Brand choice on a 2018 Jeep Trucks application often follows the role of the vehicle. Jeep owners chasing a tougher all-terrain look in Wrangler, Wrangler JK, some Cherokee fitments, or Grand Cherokee utility sizes will naturally gravitate toward the KO2 family, while a buyer using a compact Jeep and wanting whitewall or redline styling may focus on the available street-oriented radial options. Confirm the exact size first, then compare the brand choices that exist within that fitment.

In 215/65R16 for 2018 Jeep Trucks, BFGoodrich Silvertown Radial and BFGoodrich All-Terrain T/A KO2 serve very different purposes. The KO2 version uses an RBL sidewall, weighs 34 pounds, fits 6.0 to 7.5-inch rims, and carries a 103S service description with a maximum load of 1,930 pounds at 65 psi. The Silvertown Radial versions weigh 25 pounds, fit 5.50 to 7.50-inch rims, carry either redline or wide whitewall styling, and are rated at 1,565 pounds at 35 psi.

That comparison makes the buying decision fairly clear for Compass and Renegade owners using this size. KO2 points toward a more rugged, utility-minded setup with higher load and pressure capability, while Silvertown Radial leans toward visual character through its redline or whitewall presentation. Neither approach is automatically right for every 2018 Jeep Trucks application using 215/65R16, so choose according to how the vehicle is driven and the appearance you want from the finished setup.

Rim width requirements on 2018 Jeep Trucks vary by tire size. Available ranges include 215/65R16 at 5.50 to 7.50 inches, 225/65R17 at 6.0 to 8.0, 245/65R17 at 7.0 to 8.0, 245/70R17 at 6.5 to 8.0, 285/70R17 at 7.5 to 9.5, 245/75R17 at 6.5 to 7.5, 225/75R16 at 6.0 to 7.0, 245/75R16 at 6.5 to 8.0, and 265/70R17 at 7.0 to 9.0. 225/60R17 appears on a 6.5J rim example.

Those numbers matter because two tires with the same rim diameter can still call for different wheel widths. A 17-inch Cherokee or Compass wheel setup is not automatically suitable for a 17-inch Wrangler tire simply because both use 17-inch rims. Before selecting a tire for any 2018 Jeep Trucks model, compare the actual wheel width on the vehicle to the approved range for that exact size rather than assuming all same-diameter Jeep wheels interchange.

The available 2018 Jeep Trucks products shown here are modern radial sizes without any tube-type marking such as TT. Their size markings follow standard tubeless-style passenger and light truck conventions, including examples such as 225/60R17 99T, 245/70R17 119S, and 285/70R17 116Q or 121/118R. That means these Jeep applications are generally approached as tubeless radial fitments rather than vintage tube-type combinations.

Even so, the wheel itself still matters. A tire may be tubeless in design, but an older, damaged, or improperly repaired wheel can still create air-retention problems. On a 2018 Jeep Trucks vehicle, the better check before installation is whether the wheel is in sound condition, the bead seats are clean, and the valve stem is correct for the tire and wheel combination being used.

A 2018 Jeep Trucks vehicle should be stored on clean, properly inflated tires in a cool, dry place away from direct sunlight, electric motors, furnaces, welders, and other ozone-producing equipment. Ozone and UV exposure age sidewalls faster than many owners realize, especially on vehicles that spend long periods parked. Tires also benefit from a clean storage surface that keeps them out of standing moisture and away from petroleum contamination.

If the Jeep will sit for extended periods, move it occasionally to change the tire contact patch or use stands in a way that supports the vehicle safely without stressing suspension components. That matters on Wrangler, Wrangler JK, and Grand Cherokee applications with heavier utility tires, but it helps any Cherokee, Compass, or Renegade as well. A breathable cover and regular pressure checks do more for long-term tire life than simply leaving the vehicle untouched in a garage.

Tire life on a 2018 Jeep Trucks vehicle is usually better judged by age, condition, and storage history than by mileage alone. Collector-style use, weekend use, and seasonal driving can leave tread looking healthy even when the rubber is aging internally. A good rule is to begin careful age evaluation at about five to seven years and to treat around ten years from the DOT date code as the point where replacement deserves serious consideration regardless of tread depth.

That approach is especially useful for Jeep owners who drive infrequently or rotate between multiple vehicles. A low-mileage Renegade or Wrangler can still have tires that are too old for dependable road use, while a frequently used Cherokee may age its tires more by wear than by time. Check both the sidewall date code and the tire's physical condition so age, cracking, and performance changes are evaluated together rather than in isolation.

Tires on a 2018 Jeep Trucks vehicle should be inspected before every drive and again more thoroughly before any longer outing. Look for sidewall cracking, cuts, bulges, irregular wear, nails or embedded debris, and any loss of pressure from one drive to the next. On larger all-terrain Jeep applications, also watch for impact damage from curbs, rocks, and trail use that may not show up as a simple puncture.

A quick walkaround catches many problems before they become roadside issues. Wrangler and Wrangler JK owners should also inspect the spare with the same seriousness as the four road tires, since those vehicles are often expected to go farther from home. If the Jeep has not moved for a while, check pressure with a gauge instead of relying on appearance alone, because a radial tire can look acceptable while still being underinflated.

Yes, 2018 Jeep Trucks tires can be suitable for highway driving when the correct size, load capacity, and speed rating are matched to the vehicle. Available ratings here include T at 118 mph on 225/60R17, S at 112 mph on several Jeep utility sizes, Q at 99 mph on one 285/70R17 version, and R at 106 mph on another 285/70R17 version. Those ratings are well above normal U.S. highway speeds, but the exact tire version still matters within a given size.

The real limit on a longer highway trip often comes from the vehicle's condition, alignment, brakes, suspension, and loading rather than raw speed rating alone. That is particularly true on Wrangler and Wrangler JK applications fitted with heavier all-terrain tires, where pressure, balance, and steering condition strongly affect road behavior. Treat the speed symbol as a capability ceiling, not a target, and confirm that the tire's load and intended use fit the Jeep's role.

Inflation pressure for 2018 Jeep Trucks tires should follow the vehicle placard or owner's manual first, then be checked against the tire's own rated maximum figures. Available examples include 225/60R17 at 1,709 pounds at 44 psi, 215/65R16 Silvertown Radial at 1,565 pounds at 35 psi, 225/65R17 at 2,150 pounds at 65 psi, 245/70R17 at 3,000 pounds at 80 psi, and several Wrangler-family all-terrain sizes at up to 3,195 pounds at 80 psi.

Those maximum figures are not universal running pressures for every Jeep model or every driving condition. A Cherokee, Compass, Renegade, Grand Cherokee, Wrangler, and Wrangler JK each have their own factory pressure targets based on weight distribution and intended use. Use the tire's load-and-pressure rating as a limit, not as an across-the-board inflation recommendation, and avoid transferring a pressure number from one size to another just because both fit the same year and make.

Before a longer drive in a 2018 Jeep Trucks vehicle, inspect all five tires if a full-size spare is present. Check for cracking, cuts, bulges, abnormal wear, punctures, and the correct cold inflation pressure, then make sure each tire matches the intended load and speed use for that trip. On all-terrain Jeep sizes, also look closely for sidewall bruising or tread damage from previous off-road use.

Tires are only one part of the trip-prep routine on a modern Jeep, but they are the part in constant contact with the road. It also makes sense to check wheel lug torque, alignment symptoms, brake feel, fluid levels, and the condition of the jack and spare-tire tools before heading out. A short driveway inspection takes only minutes and can prevent a much bigger problem once the trip is underway.
