The 2006 Jaguar S-Type blends traditional Jaguar sedan character with a more modern performance-minded chassis, giving it a place among luxury sport sedans of its era. On this exact model, tire selection depends on trim and wheel package, with 235/50R17, 245/40R18, and a staggered 245/40R18 front plus 275/35R18 rear setup all appearing across the range. Every primary fitment here is radial, so the focus is less about vintage construction choices and more about matching the correct size, rim diameter, and front-to-rear layout. Sidewall styling, tire series, and brand selection also vary, especially in 18-inch sizes. The right choice starts with confirming the exact sub-model and wheel setup on the car.
Which Tire Size Is Right for The 2006 Jaguar S-Type
Three primary tire sizes apply to the 2006 Jaguar S-Type, and they do not all fit the same configuration. Sizes vary by sub-model and wheel diameter, with both 17-inch and 18-inch rims used, and the S-Type R adding a staggered front-and-rear arrangement. Before choosing a tire, confirm the exact sub-model and whether the car has 17-inch wheels, 18-inch sport-package wheels, or the S-Type R front and rear pairing.
Fit(s): 3.0 w/Sport Pkg., 4.2 w/Sport Pkg., and R Front
Construction: Radial|Rim: 18 in
In 245/40R18, the 245 is the nominal section width in millimeters, the 40 is the aspect ratio, R designates radial construction, and 18 is the wheel diameter in inches. This size is used on 18-inch sport-package applications and on the front of the S-Type R, so it belongs on specific Jaguar S-Type configurations rather than the whole model line. Available choices include blackwall performance-oriented tires, along with redline and raised white letter options in the Street Pro III series. It is a useful fitment to evaluate when maintaining the sharper sport-sedan look tied to the 18-inch wheel setup.
The size 235/50R17 uses a 235-millimeter nominal section width, a 50-series profile, radial construction, and a 17-inch rim diameter. On the 2006 Jaguar S-Type, this size fits the Base and VDP Edition configurations that use the 17-inch wheel package. The available product selection in this size centers on a blackwall radial from BFGoodrich in the g-Force Comp 2 AS series, which keeps the decision straightforward. This size makes sense when the car retains its original wheel diameter and the goal is a proper fitment match without moving into the 18-inch sport-package setup.
A 275/35R18 tire has a 275-millimeter nominal section width, a 35-series profile, radial construction, and it mounts on an 18-inch rim. On the 2006 Jaguar S-Type, this is a rear-only fitment for the S-Type R, where it works as part of a staggered setup with a different front tire size. Product choices are blackwall radials from BFGoodrich and Nitto across several performance-focused series, giving some room to compare brand, series, rim-width range, and load figures. This size should be selected only after confirming that the car is an R model rear application with the proper wheel width.
Sub-model fitment matters on the 2006 Jaguar S-Type because tire size changes with the wheel package, and the S-Type R uses different front and rear sizes. Identifying the exact trim is the first step before comparing tires, especially when 17-inch and 18-inch wheels are both in play.

2006 Jaguar S-Type 3.0 w/Sport Pkg.
The 2006 Jaguar S-Type 3.0 w/Sport Pkg. uses the 245/40R18 radial size. That points the selection process toward 18-inch fitment, where choices include blackwall performance tires as well as redline and raised white letter alternatives for a different visual presentation.
The 2006 Jaguar S-Type 4.2 w/Sport Pkg. also uses 245/40R18 radial tires. Tire selection therefore centers on matching the 18-inch sport-package setup and then comparing available series, sidewall style, and rim-width compatibility within that size.
The 2006 Jaguar S-Type Base uses the 235/50R17 radial size. For this sub-model, the main fitment priority is staying with the 17-inch wheel diameter and choosing a tire that matches the car's standard-wheel configuration.
The front of the 2006 Jaguar S-Type R uses 245/40R18 radial tires. Because this is part of a staggered setup, front tire choice should be made with the matching rear size in mind rather than treating the car like a square four-tire arrangement.
The rear of the 2006 Jaguar S-Type R uses the wider 275/35R18 radial size. That makes rear fitment more specialized, so wheel width and the intended front-to-rear pairing should be confirmed before selecting among the available blackwall performance tire options.
The 2006 Jaguar S-Type VDP Edition uses the 235/50R17 radial size. Tire selection is comparatively simple here, with the focus on preserving the 17-inch fitment and confirming the car has not been changed to a different wheel package.
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.
Best 2006 Jaguar S-Type Tires for Sale
Available 2006 Jaguar S-Type tires vary most in the 18-inch sizes, where BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac offerings appear across several series and sidewall styles. Buyers can compare blackwall, redline, and raised white letter choices, along with rim-width and load-related specifications where shown.
Common 2006 Jaguar S-Type tire questions usually come down to the exact size for each sub-model, 17-inch versus 18-inch wheel fitment, the S-Type R staggered setup, and how to compare available brands, sidewall styles, and maintenance checks before road use.
Tire Size & Fitment
What tire size fits a 2006 Jaguar S-Type?
The 2006 Jaguar S-Type uses three primary tire sizes: 235/50R17, 245/40R18, and 275/35R18. The Base and VDP Edition use 235/50R17, the 3.0 w/Sport Pkg. and 4.2 w/Sport Pkg. use 245/40R18, and the S-Type R uses a staggered setup with 245/40R18 in front and 275/35R18 in the rear.
Choosing the right one starts with identifying the exact sub-model and wheel package on the car. A 17-inch S-Type should not be treated the same as an 18-inch sport-package car, and the S-Type R requires attention to front and rear position because it does not use the same tire size at all four corners.
What size rim does a 2006 Jaguar S-Type use?
A 2006 Jaguar S-Type uses either a 17-inch or 18-inch rim, depending on the sub-model. The 235/50R17 fitment is matched to a 17-inch rim, while both 245/40R18 and 275/35R18 are 18-inch tire sizes. The S-Type R uses 18-inch rims in a staggered front-and-rear arrangement.
Wheel diameter should be confirmed before buying tires, especially if the car has changed hands or has aftermarket wheels. It is also worth checking actual wheel width, since some available tires in these sizes have defined rim-width ranges that matter when comparing product options within the correct diameter.
Do all 2006 Jaguar S-Type sub-models use the same tire size?
No, 2006 Jaguar S-Type sub-models do not all use the same tire size. Base and VDP Edition models use 235/50R17, sport-package 3.0 and 4.2 models use 245/40R18, and the S-Type R uses 245/40R18 front with 275/35R18 rear. That means fitment changes with trim and wheel setup.
This matters because tire shopping for an S-Type is really a trim-identification exercise first. A car wearing 18-inch wheels may still need either a square sport-package size or the S-Type R staggered pairing, so the safest next step is to verify the exact model designation and check the tires currently mounted on the car.
Choosing the Right Tire
What should I consider when choosing a tire for a 2006 Jaguar S-Type?
Start with the correct size for the specific sub-model, then compare construction, wheel diameter, and whether the car uses a square or staggered setup. On the 2006 Jaguar S-Type, every primary fitment is radial, so the main differences come from size, brand, tire series, sidewall style, rim-width compatibility, and in some cases load figures.
A Base or VDP Edition owner will usually focus on 235/50R17 options, while sport-package and S-Type R owners need to stay with the proper 18-inch fitment. It also helps to think about the car's role, whether that is everyday road use, performance-oriented driving, or preserving a particular visual style.
What sidewall styles are available for 2006 Jaguar S-Type tires?
Blackwall is the most common sidewall style available for the 2006 Jaguar S-Type tire sizes. In 245/40R18, there are also redline and RWL, or raised white letter, options through the Pro-Trac Street Pro III series. The 235/50R17 and 275/35R18 choices shown here are blackwall tires.
Sidewall style changes the car's appearance more than its fitment category, so the first step is still choosing the correct size for the sub-model. Once that is settled, sidewall treatment becomes a visual decision, especially on 18-inch sport-package cars where a redline or raised white letter can create a more assertive look.
What brands offer tires for the 2006 Jaguar S-Type?
Tires for the 2006 Jaguar S-Type are available here from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, depending on size. BFGoodrich appears across all three primary sizes, while Nitto, M&H Racemaster, and Pro-Trac are concentrated in certain 18-inch applications, especially 245/40R18 and 275/35R18.
Brand choice should come after size and wheel layout are confirmed. Once the proper fitment is established, it becomes easier to compare tire series, sidewall styling, and other product characteristics within that size instead of trying to force a preferred brand into a Jaguar S-Type configuration it was not meant to match.
Restoration & Appearance
Which tire should I choose for a period-style 2006 Jaguar S-Type?
A period-style 2006 Jaguar S-Type tire choice starts with keeping the correct size and wheel diameter for the exact sub-model. Base and VDP Edition cars point toward 235/50R17, sport-package cars use 245/40R18, and the S-Type R requires its staggered 245/40R18 front and 275/35R18 rear arrangement.
Appearance then becomes a matter of sidewall and series rather than vintage construction, since the original fitments are radial. Blackwall keeps the look restrained, while the redline and raised white letter 245/40R18 options create a more noticeable custom-performance presentation that may suit some owners better than others.
How does tire construction affect the appearance of a restored 2006 Jaguar S-Type?
On a 2006 Jaguar S-Type, construction is less of an appearance issue than it would be on an older collector car because the primary fitments are already radial. The visual changes come more from sidewall treatment, tire profile, and whether the car sits on its proper 17-inch or 18-inch wheel package.
For a restoration-minded owner, staying with the correct size and front-to-rear layout usually preserves the intended stance more effectively than chasing a particular brand name. Exact originality questions are best checked against model-specific historical references, especially if the goal is to match how a specific trim was equipped when new.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 Jaguar S-Type?
Yes, modifications can affect tire fitment on a 2006 Jaguar S-Type even when the basic tire size looks correct. Aftermarket wheels can change width or offset, suspension changes can alter clearance, and a non-original wheel package can blur the difference between 17-inch, 18-inch sport-package, and S-Type R staggered fitments.
That is why it helps to confirm more than the sidewall marking alone. Check wheel diameter, wheel width, front and rear tire sizes, and visible clearance at the fender and suspension before replacing tires, especially if the car has been lowered, upgraded, or fitted with wheels that differ from the original trim setup.
What should I inspect before driving a 2006 Jaguar S-Type on new tires?
Before driving a 2006 Jaguar S-Type on new tires, inspect the wheels for damage, confirm the correct front and rear sizes, and make sure each tire matches the intended rim diameter. It is also worth checking inflation pressure, valve stems, tread direction where applicable, and whether the car tracks evenly once the tires are installed.
A luxury sport sedan can feel very different when tire sizes or positions are mixed up, particularly on an S-Type R with staggered fitment. An early road test should include slow steering-lock checks for rubbing, a look for any uneven clearance, and a follow-up pressure check after the first stretch of driving.
How often should tires on a 2006 Jaguar S-Type be inspected?
Tires on a 2006 Jaguar S-Type should be inspected regularly, especially if the car is driven infrequently or stored for long periods. Look for tread wear, cuts, punctures, bulges, sidewall cracking, and slow air loss. Uneven wear can also signal alignment problems or a mismatch between the tire and wheel setup.
A quick visual check before driving and a more thorough inspection at routine service intervals is a practical habit for this kind of car. Extra attention is worthwhile on 18-inch applications and staggered S-Type R setups, where rotation practices differ and front-to-rear wear patterns should not be assumed to match.
