The 2011 Scion xB took the brand’s boxy, urban-minded hatchback formula and gave it everyday practicality with a distinctive profile that still stands apart from more conventional compact wagons. Buyers looking after one today are often balancing daily-driver usability with the desire to keep the xB’s stance and appearance true to its character. Tire fitment centers on two radial sizes, 205/55R16 and 225/45R17, so the first step is confirming which wheel package is on the car. From there, the real choice becomes tread style, sidewall presentation, and whether the goal is a modern performance look or a more custom appearance. Getting that decision right starts with the exact wheel diameter and intended use.
Which Tire Size Is Right for The 2011 Scion xB
The 2011 Scion xB uses two primary tire sizes, and both are radial fitments tied to different wheel diameters: 16-inch and 17-inch. Because the Base sub-model can use either size, the first thing to confirm is the actual wheel diameter on the car. Once that is settled, the decision shifts to choosing the right tire series, sidewall style, and road-use character within the correct size.
205/55R16 is a metric radial size in which 205 identifies the nominal section width in millimeters, 55 is the aspect ratio, R marks radial construction, and 16 is the wheel diameter in inches. On the 2011 Scion xB, this size suits the 16-inch wheel setup and keeps the selection centered on modern radial construction. Available choices include Blackwall and Wide Whitewall styles from brands such as BFGoodrich, Michelin, and American Classic, with series ranging from g-Force designs to a classic-style radial. This size is the right starting point when the car is riding on 16-inch wheels and the goal is to match both fitment and appearance to the intended use.
225/45R17 is a metric radial size that uses a 225-millimeter nominal section width, a 45-series aspect ratio, radial construction, and a 17-inch wheel diameter. On the 2011 Scion xB, it belongs to the 17-inch wheel package and introduces a lower-profile fitment than the 16-inch option. Product choices include Blackwall, raised white letter, and Redline sidewalls from BFGoodrich, Nitto, and Pro-Trac across series such as g-Force, NT555 G2, and Street Pro III. This size deserves a closer look when the xB has 17-inch wheels and the buyer wants either a sportier presentation or a more custom sidewall treatment.
2011 Scion xB sub-model fitment is straightforward because the covered Base model can use either of the two primary radial sizes. The key is not trim identification so much as confirming whether the car has the 16-inch or 17-inch wheel setup before choosing a tire.

2011 Scion xB Base
The 2011 Scion xB Base can use either the 205/55R16 or 225/45R17 radial fitment, depending on the wheel package installed on the car. That makes wheel-diameter confirmation the essential first step, followed by choosing the tire series and sidewall style that best matches daily use, a sportier look, or a more custom presentation.
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.

Common 2011 Scion xB tire questions usually come down to wheel-size confirmation, choosing between the two correct radial sizes, and sorting through sidewall and series options. Buyers also tend to ask about modifications, maintenance, and what to inspect before regular road use.
Tire Size & Fitment
What tire size fits a 2011 Scion xB?
A 2011 Scion xB uses either 205/55R16 or 225/45R17, and both are radial tire sizes. Those two sizes are tied to different wheel diameters, so the correct choice depends on whether the car is equipped with a 16-inch or 17-inch wheel setup.
That means the first step is checking the wheel diameter currently on the car rather than choosing by appearance alone. A Base model may use either size, so a quick look at the wheel and the existing tire sidewall will usually settle the question before comparing brands, sidewall styles, or tire series.
What size rim does a 2011 Scion xB use?
The 2011 Scion xB uses either a 16-inch or 17-inch rim, depending on which tire size is fitted. The 205/55R16 tire belongs on a 16-inch rim, while the 225/45R17 tire belongs on a 17-inch rim.
Rim diameter needs to match the tire size exactly, so this is the most important fitment check before selecting a tire. Wheel width also matters once the diameter is confirmed, especially if the car has aftermarket wheels, since available products within these sizes can carry different recommended rim-width ranges.
Why does the 2011 Scion xB have more than one tire size?
The 2011 Scion xB has more than one tire size because it can be equipped with two different wheel diameters. One setup uses 205/55R16 on a 16-inch rim, and the other uses 225/45R17 on a 17-inch rim.
This is not a case of picking whichever size looks better on the same wheel. Each tire size corresponds to a specific rim diameter, so the actual wheel on the car decides the correct starting point. Once that is confirmed, the selection becomes much easier and can focus on construction details, sidewall treatment, and intended driving use.
Choosing the Right Tire
What should I consider when choosing a tire for a 2011 Scion xB?
Start with the correct size for the wheel package: 205/55R16 for 16-inch rims or 225/45R17 for 17-inch rims. From there, compare radial tire series, sidewall style, rim-width compatibility, and any product load and weight details that matter for how the xB will be used.
A daily-driven xB may call for a different choice than one built around a custom look or a sportier presentation. Blackwall tires keep the appearance straightforward, while Wide Whitewall, Redline, or raised white letter options change the visual character. Matching the tire to the wheel setup and the way the car is actually driven usually leads to the best decision.
What sidewall styles are available for 2011 Scion xB tires?
2011 Scion xB tires are available with several sidewall presentations, including Blackwall, Wide Whitewall, Redline, and raised white letter styling. The available sidewall treatment depends on the tire size and series, so not every style appears in both wheel packages.
That gives the xB owner some room to shape the car’s look without leaving the correct size range. A Blackwall tire keeps things modern and understated, while Whitewall, Redline, or raised white letter options create a more customized appearance. It is still important to begin with the proper 16-inch or 17-inch fitment before narrowing the choice by style.
What brands offer tires for the 2011 Scion xB?
Tires for the 2011 Scion xB are available from BFGoodrich, Michelin, American Classic, Nitto, and Pro-Trac. Brand availability depends on tire size, with some brands appearing in the 16-inch fitment, some in the 17-inch fitment, and BFGoodrich offering choices in both.
Brand is only one part of the decision. The better comparison is how each option aligns with the correct size, the wheel width on the car, the preferred sidewall treatment, and the intended road use. Looking at the full combination of size, series, and appearance usually tells more than the brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 2011 Scion xB?
A period-style 2011 Scion xB tire choice starts with the correct wheel-size fitment and then moves to the look you want the car to carry. In 205/55R16, an American Classic Radial with a 1.50 inch whitewall creates a distinctly traditional custom presentation, while Blackwall performance-oriented radials keep the appearance closer to a late-model street hatchback.
The best choice depends on whether the xB is being preserved as a clean early-2010s compact or styled with more personality. Since this is a newer vehicle than most restoration subjects, appearance often matters more than strict originality. Keeping the right size and wheel diameter in place is still what makes the visual decision work properly.
How does tire construction affect the appearance of a restored 2011 Scion xB?
On a 2011 Scion xB, construction is straightforward because the primary fitments are radial rather than bias-ply. That means the visual difference comes less from construction type and more from profile, series character, and sidewall treatment within the correct 205/55R16 or 225/45R17 size.
A Blackwall radial gives the xB a cleaner modern look, while a Whitewall, Redline, or raised white letter tire pushes the car toward a more customized presentation. Owners trying to preserve a stock-appearing build should pay close attention to wheel size and overall visual proportion, since those choices shape the finished look as much as the tire itself.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2011 Scion xB?
Yes, modifications can affect tire fitment on a 2011 Scion xB even when the tire size itself is correct. Aftermarket wheels, changes in wheel width or offset, lowering, suspension wear, or body alterations can all change how a 205/55R16 or 225/45R17 tire sits in the wheel opening.
That is why the wheel diameter alone is not the whole story on a modified xB. Clearance at the fender edge, inner wheelhouse, and steering range should be checked before settling on a tire, especially with the 17-inch setup. A car that no longer rides at stock height deserves a closer fitment review before regular road use.
What should I inspect before driving a 2011 Scion xB on new tires?
Before driving a 2011 Scion xB on new tires, inspect the wheel condition, valve stems, and the actual size mounted on the car. It also helps to check tread seating, verify inflation pressure, and look over the suspension and alignment condition so the new tires begin service on a sound foundation.
A short, careful road test is worthwhile after installation to confirm there is no rubbing, vibration, or pull. The xB can use either 16-inch or 17-inch fitment, so this is also the right time to make sure the tire matches the wheel package exactly. Catching those details early helps prevent uneven wear and avoidable fitment trouble.
How often should tires on a 2011 Scion xB be inspected?
Tires on a 2011 Scion xB should be inspected regularly, not just when wear becomes obvious. A quick visual check for air loss, cuts, bulges, cracking, and uneven tread wear is smart throughout the year, especially on a car that sees mixed city driving, longer highway trips, or seasonal storage.
Inspection matters just as much on low-use vehicles as it does on daily drivers. A tire can look acceptable at a glance and still have age, pressure, or wear issues that affect road manners. Checking condition routinely and correcting inflation before use helps either xB tire size deliver more consistent service and a better driving feel.
