Tire choices for family road trips in a Grand Cherokee
- For long highway days with passengers and luggage, start with a quiet, comfortable all-season touring tire.
- NEXEN TIRE ROADIAN GTX comes in 265/60R18 110H and 265/50R20 XL 111V and is built for comfort, low noise and long tread life.
- Count passengers and luggage against the vehicle’s load limit; a higher tire load index does not raise it.
- Add a 3PMSF-marked tire or a winter set if the trip crosses snow country.
A family road trip puts a Grand Cherokee near its load limit for hours of highway driving, so comfort, quietness and correct load capacity matter more than trail grip. This guide compares road-trip tires for 2026 and walks through the load and pressure checks to do before you leave. The model years below are examples, not fitment for every trim.
Narrow the choices by your driving and your Grand Cherokee’s fitment
Use the door-area placard for size and cold pressure. Check load index and speed symbol against the original-equipment tire and vehicle documentation; Jeep’s replacement guidance identifies the OE sidewall as the source of those markings.
Pirelli’s Grand Cherokee catalog asks shoppers for the vehicle year and version, then directs them to compare technical data for the available tire options.
The 3PMSF marking establishes a specified traction result on medium-packed snow. It does not certify ice braking; M+S alone does not establish the same snow test.
Grand Cherokees with four-wheel drive or all-wheel drive need extra attention to tire diameter and matching. Goodyear’s tire-mixing bulletin directs owners to follow the vehicle manual because even small differences in outside diameter can damage the drivetrain or cause a malfunction. The same bulletin advises against mixing tire sizes or tread patterns on 4WD and AWD vehicles when the manual gives no different instructions.
For long, loaded highway days: NEXEN TIRE ROADIAN GTX
For reference, Michelin’s U.S. vehicle selector shows 265/60R18 110H for a 2025 Grand Cherokee L Laredo X and 265/50R20 107V for a 2023 Grand Cherokee L Summit; use your own placard and documentation for your vehicle.
NEXEN TIRE ROADIAN GTX is an all-season touring tire for SUVs and crossovers built around long tread life, comfort and low noise. Its compound is engineered to keep performance stable across a wide range of temperatures, and an optimized zigzag tread pattern spreads road pressure more evenly. It is H, V and W speed rated, with UTQG grades of 540, 600 or 680 A A depending on size. In common Grand Cherokee sizes, NEXEN TIRE lists ROADIAN GTX in 265/60R18 110H (product code 17057) and 265/50R20 XL 111V (product code 17040), which meet the H and V ratings in the factory examples above. NEXEN TIRE lists a maximum load of 2,337 pounds per tire for the 265/60R18 and 2,403 pounds for the 265/50R20 XL. NEXEN TIRE also supplies ROADIAN GTX as original equipment on the 2026 Jeep Cherokee, a different Jeep model, so check fitment for your Grand Cherokee’s year and trim.
Michelin’s 2025 Grand Cherokee L listing: Defender LTX M/S2
Michelin’s U.S. vehicle selector lists the Defender LTX M/S2 for a specific 2025 Grand Cherokee L Laredo X configuration.
Michelin’s 2025 Grand Cherokee L Laredo X listing shows Defender LTX M/S2 as an all-season option in 265/60R18 XL 114H. A different model year, trim or wheel package needs a separate fitment check.
Rain and occasional snow: Michelin CrossClimate2
Consider the Michelin CrossClimate2 when one set needs to cover wet roads and occasional light-to-moderate snow. Michelin calls it an all-season tire and lists the 3PMSF marking, so it offers a snow-rated option for drivers who want to keep one set on the vehicle through changing seasons.
On its CrossClimate2 product page, Michelin identifies an all-season tire with 3PMSF marking. For recurring ice or heavy snow, prioritize a dedicated winter set. The distinction matters for a family road trip: a snowflake marking helps identify tested snow traction, while frequent ice or severe winter travel still favors a dedicated winter tire.
The Michelin page establishes the tire’s category and marking; the Jeep placard and a vehicle-specific fitment listing establish whether a particular size suits your year and trim.
A road-focused alternative: Continental CrossContact LX25
Continental describes CrossContact LX25 as an all-season touring tire for crossovers and SUVs, with low road noise among its design priorities. That makes it a useful pavement-oriented comparison where an approved size and service rating are available.
Michelin’s 2021 disclosure compares CrossClimate2 and LX25 on other vehicles, including wet braking on a 2020 RAV4 and treadwear on a 2020 Equinox. Those results are conditional test evidence, not stopping-distance or tire-life predictions for a loaded Grand Cherokee. For the road trip, start with fitment, load and the weather you will actually encounter.
Frequent ice and snow: choose dedicated winter tires
Choose dedicated winter tires when regular routes include frequent ice, packed snow or sustained winter conditions. Winter compounds are designed for cold-weather use. Follow the vehicle and tire manufacturers’ seasonal guidance; a single temperature is not a universal switch point for every all-season compound.
Use four matching winter tires so the vehicle has winter traction at every wheel. For occasional snow, a 3PMSF-marked all-season or all-terrain tire can suit the route; frequent ice and severe winter travel favor dedicated winter tires.
Match a winter set to the same vehicle requirements as a warm-weather set. A winter tire that fits the rim but falls short of the vehicle’s service requirements is the wrong choice.
Compare the options for this use
For a road trip, compare comfort-oriented all-season tires first, then add snow capability if your route needs it.

Check the exact fit before buying
- Record the vehicle details. Write down the Grand Cherokee model year, trim, drivetrain, wheel size, and the complete size on the door placard.
- Match the service ratings. Compare the tire size with the placard and verify the service ratings against the vehicle documentation and OE specification. The Tire Industry Association says a replacement tire’s load index must not fall below the original-equipment tire’s rating.
- Check the trip load and cold pressure. Count passengers and luggage against the vehicle’s load limits, then use its specified cold inflation pressures. A higher tire load index does not increase the vehicle’s payload limit.
- 4WD and AWD: Follow the owner’s manual for tire mixing and size changes because small outside-diameter differences can damage the drivetrain or cause a malfunction. Goodyear’s bulletin warns that even small outside-diameter differences can affect the drivetrain.
- Custom tire-and-wheel packages: The Tire Industry Association recommends consulting a tire professional when a custom setup differs from the placard information.
- Finish with the season and route. Choose a road all-season for pavement, a 3PMSF tire for occasional snow needs, an all-terrain tire when gravel or trails are regular, and dedicated winter tires for frequent ice or deep snow.
Choose by your usual roads and winter conditions, then select a tire whose full size, load and speed specifications meet the Grand Cherokee’s placard and drivetrain instructions.
FAQ
What tires are best for a family road trip in a Jeep Grand Cherokee?
A quiet, comfortable all-season touring tire that matches the placard suits long highway days. NEXEN TIRE ROADIAN GTX is built for comfort, low noise and long tread life and comes in 265/60R18 110H and 265/50R20 XL 111V. Check your own placard for the size and ratings your vehicle needs.
Does a fully loaded Grand Cherokee need a higher load index?
No. Match at least the load index on the original tire and keep passengers and luggage within the vehicle’s stated capacity, because a higher load index does not raise the vehicle’s limit. NEXEN TIRE lists ROADIAN GTX at 2,337 pounds per tire in 265/60R18 110H and 2,403 pounds in 265/50R20 XL 111V.
Should I check tire pressure before a long road trip?
Yes. Check all four tires cold, before driving, and set them to the pressure on the door placard for the loaded vehicle. Recheck after the first long stop, and inspect your NEXEN TIRE ROADIAN GTX or other tires for cuts or bulges before leaving.
