The 2016 Lexus IS300 sits in the modern sport-sedan category where sharp handling, balanced proportions, and a refined chassis all depend on getting tire fitment right. For this generation, tire selection is tied closely to wheel setup, because the IS300 can appear with a 17-inch square fitment or an 18-inch staggered arrangement using different front and rear sizes. Its primary fitments are all radial, including 225/45R17, 225/40R18, and 255/35R18. Available choices span Blackwall performance-oriented lines, with additional raised white letter and Redline options in 225/45R17. The key is confirming the exact sub-model and wheel layout before comparing tire series, appearance, and road-use priorities.
Which Tire Size Is Right for The 2016 Lexus IS300
The 2016 Lexus IS300 uses three primary tire sizes, and the right one depends on whether the car has the 17-inch Base setup or the 18-inch front and rear staggered arrangement used on other configurations. Start by confirming the exact sub-model and wheel diameter, then verify whether the car uses the same size at all four corners or different front and rear tires before choosing among the available radial options.
225/45R17 is a metric radial size where 225 identifies nominal section width in millimeters, 45 is the aspect ratio, R denotes radial construction, and 17 is the rim diameter in inches. On the 2016 Lexus IS300, this size belongs to the 17-inch wheel setup rather than the staggered 18-inch arrangement. Product choices include BFGoodrich, Nitto, and Pro-Trac, with Blackwall, raised white letter, and Redline sidewall treatments depending on the tire line. This size makes the most sense when the car retains its 17-inch wheel package and the goal is to match that specific fitment before comparing style and performance character.
225/40R18 is a metric radial size with a 225-millimeter nominal section width, a 40-series profile, and an 18-inch rim diameter. For the 2016 Lexus IS300, this size serves as a front fitment on the 18-inch staggered setup, so it should be evaluated together with the matching rear size rather than as a stand-alone four-corner choice. Available options come from BFGoodrich and Nitto, all in Blackwall form across several g-Force and NT555 G2 series selections. It is the right size to compare when the front wheels measure 18 inches and the car is set up with wider rear tires.
255/35R18 is a metric radial size where 255 indicates a wider nominal section width in millimeters, 35 is the aspect ratio, and 18 is the wheel diameter in inches. On the 2016 Lexus IS300, this is the rear tire size used with the 18-inch staggered configuration, paired with a narrower 225/40R18 front tire. BFGoodrich and Nitto both offer this size in Blackwall performance-oriented series, giving buyers room to compare line character, load figures where shown, and rim-width compatibility. This size should be chosen only after confirming the car uses the staggered rear-wheel fitment.
Sub-model fitment matters on the 2016 Lexus IS300 because one configuration uses a 17-inch square setup while others use 18-inch front and rear sizes. Checking the exact sub-model and wheel layout is the first step before comparing tire series, sidewall style, or other product differences.

2016 Lexus IS300 Base
The 2016 Lexus IS300 Base uses the 225/45R17 radial size, which points to the 17-inch wheel package rather than the staggered 18-inch arrangement. Tire selection here centers on choosing the right 17-inch radial by brand, series, and sidewall appearance while keeping the wheel setup consistent.
The 2016 Lexus IS300 Base Front uses 225/40R18 as part of a front-and-rear staggered radial fitment. That means the front tire should be matched to the proper rear size and checked against the actual 18-inch wheel setup before choosing among the available Blackwall performance lines.
The 2016 Lexus IS300 Base Rear uses 255/35R18 on the back of the staggered 18-inch setup. Rear tire selection should be made with the matching front size in mind, with attention to wheel width and the wider rear fitment this configuration requires.
The 2016 Lexus IS300 F Sport Front uses the same 225/40R18 radial size as the front position on the staggered 18-inch layout. Choosing this tire starts with confirming the front wheel diameter and then comparing the available Blackwall series for the intended balance of appearance and use.
The 2016 Lexus IS300 F Sport Rear uses 255/35R18, completing the wider rear side of the staggered 18-inch fitment. That makes rear tire choice less about alternative sizing and more about matching the correct rear specification to the wheel and front tire arrangement already on the car.
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.

Tire questions for the 2016 Lexus IS300 usually come down to size, wheel diameter, and whether the car uses a square or staggered setup. The FAQs below focus on fitment, product selection, appearance options, and the checks worth making before road use.
Tire Size & Fitment
What tire size fits a 2016 Lexus IS300?
The 2016 Lexus IS300 uses three primary tire sizes: 225/45R17, 225/40R18, and 255/35R18. The 225/45R17 size belongs to the 17-inch Base setup, while 225/40R18 and 255/35R18 are used as front and rear sizes on the 18-inch staggered arrangement.
The practical step is confirming which wheel package is actually on the car before selecting tires. A square 17-inch setup and a staggered 18-inch setup are not the same buying decision, and any car with replacement wheels should have its front and rear sizes checked directly at the tire and wheel before ordering.
What size rim does a 2016 Lexus IS300 use?
The 2016 Lexus IS300 uses either a 17-inch or 18-inch rim, depending on configuration. The 225/45R17 fitment uses a 17-inch rim, while the 225/40R18 front and 255/35R18 rear fitments use 18-inch rims.
Rim diameter is the first thing to verify because it determines which tire sizes are even in the running. After that, confirm whether the car has the same wheel size at all four corners or a staggered front and rear setup, especially if the car has been modified or purchased used with non-original wheels.
Why does the 2016 Lexus IS300 have more than one tire size?
More than one tire size applies because the 2016 Lexus IS300 was available with different wheel layouts. One version uses 225/45R17, while the 18-inch setup uses a staggered fitment with 225/40R18 in front and 255/35R18 in the rear.
That difference affects more than just ordering tires. It changes how the car should be measured and matched front to rear, so the buyer should identify the exact sub-model and inspect the current wheel and tire combination before choosing a replacement, rather than assuming every IS300 uses the same size.
Choosing the Right Tire
What should I consider when choosing a tire for a 2016 Lexus IS300?
Start with the exact tire size and wheel setup on the car, because the 2016 Lexus IS300 can use either 225/45R17 or a staggered 225/40R18 front with 255/35R18 rear. From there, compare radial tire series, rim-width compatibility, load figures where shown, and sidewall style.
Appearance and intended use both matter. A Blackwall performance tire suits the modern sport-sedan character of the IS300, while 225/45R17 also opens the door to raised white letter or Redline styling. Matching the tire to the actual wheel package keeps the buying decision focused and avoids mixing incompatible front and rear fitments.
What sidewall styles are available for 2016 Lexus IS300 tires?
Blackwall is the most common sidewall style for the 2016 Lexus IS300 across all three primary tire sizes. In 225/45R17, additional sidewall options include raised white letter and Redline, both offered in the Pro-Trac Street Pro III line.
Those appearance choices mainly matter for the 17-inch setup, since the 18-inch front and rear sizes stay focused on Blackwall performance options. A buyer choosing among sidewall styles should still begin with the correct tire size and rim diameter, then decide whether the car calls for a modern low-key look or something with more visual character.
What brands offer tires for the 2016 Lexus IS300?
BFGoodrich, Nitto, and Pro-Trac offer tires for the 2016 Lexus IS300. BFGoodrich appears across all three primary sizes in several g-Force lines, Nitto covers each fitment with the NT555 G2, and Pro-Trac appears in 225/45R17 with Street Pro III options.
Brand comparison is most useful after size has been settled, because not every brand or series appears in every fitment. On the 17-inch size, the product mix includes more appearance variety, while the 18-inch front and rear sizes stay concentrated on Blackwall radial performance lines that should be matched correctly to the car's wheel layout.
Restoration & Appearance
Which tire should I choose for a period-style 2016 Lexus IS300?
A period-style approach for a 2016 Lexus IS300 still starts with the correct modern radial size for the car's actual wheel setup. The 17-inch 225/45R17 fitment gives the broadest appearance range, including Blackwall, raised white letter, and Redline choices, while the 18-inch staggered setup stays within Blackwall performance-oriented selections.
That means appearance goals should be balanced with the way the car is configured today. A cleaner contemporary look points naturally toward Blackwall tires, while the 17-inch setup leaves more room for visual customization. Any appearance choice should remain secondary to confirming size, rim diameter, and front-to-rear fitment.
How does tire construction affect the appearance of a restored 2016 Lexus IS300?
Tire construction is straightforward on the 2016 Lexus IS300 because the primary fitments are radial. The visual differences come less from changing construction and more from sidewall treatment, tire series, and whether the car wears the 17-inch square setup or the 18-inch staggered combination.
For an owner focused on presentation, the strongest appearance decisions are Blackwall versus raised white letter or Redline in 225/45R17, along with maintaining the intended front and rear proportions on staggered 18-inch cars. Keeping those details aligned helps the car look coherent without drifting away from the proper fitment foundation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2016 Lexus IS300?
Yes, modifications can change tire fitment on a 2016 Lexus IS300. Aftermarket wheels, altered wheel widths, suspension changes, lowering, or body modifications can all affect whether the original 225/45R17 or staggered 225/40R18 and 255/35R18 sizing still makes sense on the car.
A modified IS300 should be checked at all four corners before replacement tires are chosen. Wheel diameter, actual wheel width, and front-to-rear consistency matter, and clearance at the fender, steering, and suspension should be confirmed directly instead of assuming the current setup matches the original tire arrangement.
What should I inspect before driving a 2016 Lexus IS300 on new tires?
Before driving a 2016 Lexus IS300 on new tires, inspect the wheel size, confirm the correct front and rear tire positions, and verify proper inflation. It also helps to look at the wheel condition, valve stems, and any signs of rubbing or uneven wear that may point to an alignment or suspension issue.
A quick road-use check should also include sidewall clearance at full steering lock and normal ride height, especially on staggered 18-inch cars or vehicles with wheel changes. After the first miles, recheck pressure and look for any fresh contact marks so small fitment issues are caught before they become expensive ones.
How often should tires on a 2016 Lexus IS300 be inspected?
Tires on a 2016 Lexus IS300 should be inspected regularly, not just when tread looks low. Pressure, tread wear pattern, sidewall condition, and any signs of cuts, bulges, or air loss all deserve routine attention, particularly on a performance-oriented fitment where front and rear sizes may differ.
Inspection is even more important if the car sees seasonal use or sits for extended periods. Looking over the tires before longer drives helps catch aging, irregular wear, or position mix-ups on staggered setups, and it gives the owner a chance to confirm that front and rear tires are still matched to the correct wheel locations.
