The 2013 Lincoln Trucks Navigator sits in the full-size luxury SUV class, blending truck-based capability with the upscale road presence that made the Navigator a recognizable name in premium American utility vehicles. Buyers looking at one today are often balancing everyday drivability with the need to keep the vehicle's stance and wheel setup true to its original character. Tire fitment centers on two radial sizes, 255/70R18 and 275/55R20, depending on the wheel package installed. That makes wheel diameter the first thing to confirm before comparing replacement options. Once that is settled, the real choice is selecting the right radial tire style for road use, appearance, and overall fitment confidence.
Which Tire Size Is Right for The 2013 Lincoln Trucks Navigator
The 2013 Lincoln Trucks Navigator uses two primary tire sizes, and both are radial fitments tied to different wheel diameters. Before choosing a tire, confirm whether the vehicle is on 18-inch or 20-inch wheels, since that determines whether 255/70R18 or 275/55R20 applies. Once wheel diameter is confirmed, the decision becomes selecting the right radial tire within that size for the vehicle's current setup and intended road use.
255/70R18 is a metric radial size in which 255 identifies the nominal section width in millimeters, 70 is the aspect ratio, R denotes radial construction, and 18 is the wheel diameter in inches. On the 2013 Lincoln Trucks Navigator, this size suits vehicles equipped with 18-inch wheels and delivers the taller-profile look associated with that wheel package. Its published dimensions include an overall diameter of 32.06 inches and a section width of 10.04 inches. This is the size to evaluate when maintaining the 18-inch wheel setup and checking replacement fitment against the vehicle's actual wheel and clearance configuration.
275/55R20 is a metric radial size where 275 indicates nominal section width in millimeters, 55 is the aspect ratio, R marks radial construction, and 20 identifies the wheel diameter in inches. On the 2013 Lincoln Trucks Navigator, this size applies to vehicles running 20-inch wheels and gives a wider, lower-profile presentation than the 18-inch fitment. Its published dimensions include an overall diameter of 31.91 inches and a section width of 10.83 inches. This size should be considered when the Navigator already has the 20-inch wheel package and the goal is to stay aligned with that wheel diameter and profile.
Fitment is straightforward across the covered 2013 Lincoln Trucks Navigator sub-models because both Base and L can use the same two radial tire sizes. The key step is confirming whether the vehicle is on 18-inch or 20-inch wheels before choosing between the two sizes.

2013 Lincoln Trucks Navigator Base
The 2013 Lincoln Trucks Navigator Base can use either of the two primary radial tire sizes, depending on which wheel package is on the vehicle. Tire selection starts with confirming wheel diameter, then choosing a replacement that matches the intended road use and preserves proper fitment.
The 2013 Lincoln Trucks Navigator L follows the same fitment pattern, with both primary radial sizes used according to wheel diameter. That means the important check is not trim level alone, but the actual 18-inch or 20-inch wheel setup currently installed on the vehicle.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Frequently Asked Questions
These FAQs focus on the two tire sizes used on the 2013 Lincoln Trucks Navigator, along with wheel-diameter confirmation, sub-model fitment, replacement selection, and the maintenance checks that matter before putting a full-size luxury SUV back on the road.
Tire Size & Fitment
What tire size fits a 2013 Lincoln Trucks Navigator?
The 2013 Lincoln Trucks Navigator uses two primary tire sizes: 255/70R18 and 275/55R20. Both are radial sizes, and the correct one depends on the wheel diameter installed on the vehicle rather than a change in tire construction.
The practical first step is checking whether the Navigator has 18-inch or 20-inch wheels. The 255/70R18 size belongs with the 18-inch setup, while 275/55R20 belongs with the 20-inch setup. If the SUV has had wheel changes at some point, verify the actual wheel size on the vehicle before choosing tires.
What size rim does a 2013 Lincoln Trucks Navigator use?
A 2013 Lincoln Trucks Navigator uses either an 18-inch or 20-inch rim, depending on which tire size is on the vehicle. The 255/70R18 size is paired with an 18-inch rim, and the 275/55R20 size is paired with a 20-inch rim.
Rim diameter should be confirmed before anything else because neither tire size crosses over to the other wheel size. It is also worth checking the actual wheels on the vehicle instead of relying only on trim name, since replacement wheels or previous owner changes can alter what the Navigator needs today.
Do all 2013 Lincoln Trucks Navigator sub-models use the same tire size?
Both the 2013 Lincoln Trucks Navigator Base and the 2013 Lincoln Trucks Navigator L use the same two available tire sizes: 255/70R18 and 275/55R20. Fitment is shared across these sub-models, with wheel diameter determining which of the two sizes applies.
That makes the tire decision more about the wheel package than the sub-model badge. A Base or L on 18-inch wheels takes 255/70R18, while one on 20-inch wheels takes 275/55R20. Taking a quick look at the tire sidewall or wheel itself helps confirm the correct size before ordering replacements.
Choosing the Right Tire
What should I consider when choosing a tire for a 2013 Lincoln Trucks Navigator?
Start with the correct primary size for the wheel package on the vehicle: 255/70R18 for 18-inch wheels or 275/55R20 for 20-inch wheels. Since both fitments are radial, the main concern is matching the installed wheel diameter and staying within the size the Navigator was set up to use.
After size is confirmed, compare the tire's overall fit with the way the SUV is actually used. A stock-height Navigator with original-style wheels is a different situation than one with aftermarket wheels or suspension changes. Checking wheel dimensions, clearance, and the vehicle's current stance helps avoid choosing a tire that looks or fits differently than expected.
How do I choose between the available 255/70R18 and 275/55R20 tires for a 2013 Lincoln Trucks Navigator?
The choice between 255/70R18 and 275/55R20 is not a matter of preference alone, because each size belongs to a different wheel diameter. The correct decision is tied to whether the 2013 Lincoln Trucks Navigator is equipped with 18-inch wheels or 20-inch wheels.
Once the wheel diameter is confirmed, compare the proportions of the two sizes rather than treating them as interchangeable. The 255/70R18 carries a taller sidewall, while the 275/55R20 pairs with a wider, lower-profile presentation. That difference affects the vehicle's look, so keeping the existing wheel-and-tire relationship in mind leads to a more consistent replacement choice.
Why does the 2013 Lincoln Trucks Navigator have more than one tire size?
The 2013 Lincoln Trucks Navigator has more than one tire size because it was fitted with more than one wheel diameter. The two primary combinations are 255/70R18 on 18-inch wheels and 275/55R20 on 20-inch wheels, both in radial construction.
That means the extra size is not a conflict in fitment so much as a reflection of different wheel packages. Buyers should avoid assuming that one size is automatically suitable just because it appears on the same model line. Confirming the wheel diameter on the actual vehicle keeps the replacement search centered on the tire size it was built to use.
Restoration & Appearance
Does correct tire fitment matter for a 2013 Lincoln Trucks Navigator restoration?
Correct tire fitment matters on a 2013 Lincoln Trucks Navigator because the tire size works hand in hand with the wheel package and the SUV's original proportions. Using the proper 255/70R18 or 275/55R20 size helps preserve the stance and visual balance intended for the vehicle.
Restoration-oriented buyers usually want the truck to sit and present itself the way a Navigator of this era should, even if the goal is road use rather than show judging. That makes wheel diameter confirmation especially important. If originality is a concern, compare the current wheels and tires to period vehicle literature or marque-specific references before making a change.
Which tire should I choose for a period-style 2013 Lincoln Trucks Navigator?
A period-style choice for a 2013 Lincoln Trucks Navigator starts with retaining the wheel diameter and tire size the vehicle is already set up to use. That means staying with 255/70R18 on an 18-inch package or 275/55R20 on a 20-inch package, both of which reflect the model's original-era radial fitment approach.
The goal is usually to keep the SUV's proportions looking appropriate for its model year rather than forcing a different profile onto it. Moving away from the existing wheel package can change the appearance noticeably. Checking the current wheel setup and comparing overall tire dimensions helps maintain a more authentic visual result.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2013 Lincoln Trucks Navigator?
Yes, modifications can affect tire fitment on a 2013 Lincoln Trucks Navigator. Even though the primary sizes are 255/70R18 and 275/55R20, aftermarket wheels, changes in wheel offset, suspension alterations, or body modifications can all change the amount of room available around the tire.
A Navigator with stock wheels and ride height is one situation, while a lowered truck or one fitted with non-stock rims is another. Checking the actual wheel diameter, wheel width, and clearance at steering lock and through suspension movement is a smart step before choosing replacement tires for a modified vehicle.
What should I inspect before driving a 2013 Lincoln Trucks Navigator on new tires?
Before driving a 2013 Lincoln Trucks Navigator on new tires, inspect the wheels for damage, confirm the tire size matches the wheel diameter, and make sure each tire is seated and inflated correctly. It is also wise to look over the suspension and steering components if the vehicle has been sitting or has uneven previous tire wear.
A quick road-use inspection should also include checking for rubbing at full steering lock, verifying even clearance around the fenders, and making sure the vehicle tracks normally once the tires are installed. On a full-size luxury SUV, small fitment issues can become more noticeable quickly, especially if wheel or suspension changes are already present.
How often should tires on a 2013 Lincoln Trucks Navigator be inspected?
Tires on a 2013 Lincoln Trucks Navigator should be inspected regularly, especially if the SUV sees seasonal use, long periods of storage, or mixed daily driving and highway use. Routine checks should cover tread wear, sidewall condition, cuts, bulges, and any signs of slow air loss.
Periodic inspection matters just as much as size selection because even the correct 255/70R18 or 275/55R20 tire can become a problem if age or condition is overlooked. Looking at the tires before longer trips, after storage, and whenever ride quality changes helps catch issues early and keeps the Navigator more confidence-inspiring on the road.
