The Sport continues the eccentric Land Rover tradition of specifying odd-sized tires that are hard to find. However, under the new Ford management, Land Rover was able to persuade Continental Tire to make a special tire which combines good on-road ability with reasonable off-road ability for mild conditions.
As usual, the tires specified by the manufacturer are very
usual, are rated for a far higher speed than even a Range Rover
Sport can actually
go, so any owner who is a serious off-highway enthusiast can be excused
for being tempted to try and improve on the stock rubber.
The Range Rover Sport is based on the Discovery 3 / LR
3 platform, so the wheels should be interchangeable. Whether they are
interchangeable with wheels for the Range Rover III, I am not sure -- one owner
reports that his dealer says they are not.
Entry level wheel on TD6 (world markets outside North America): 17x7 inch 5 split spoke -- same as base wheels for Discovery 3
Standard wheel (SE V8 models outside North America) 18x8 inch -- same as Discovery 3 / LR3 stock wheels.
Standard wheel (North America naturally aspirated) and optional size (rest of world): 19x9 inch rims; same as Discovery 3 / LR3 optional wheels. US Stock 19 inch wheel part number RRC502280MNH.
Standard fitment (supercharged models, all markets): 20x9.5 inch rims.
Note that the Range Rover III seems particularly prone to vibration problems with the 19 inch wheels (see Mark III common problems and fixes) but I have not yet heard of this problem recurring on the Sport. (However there was a problem with early RR Sports and 20 inch wheels, prior to installation of a modified steering rack with a vibration damper).
As far as I know16 inch or smaller wheels are not available -- the brakes are too big to allow them. On the supercharged model, for example, the front brake disks are 14.2 inches in diameter -- the calipers wlil add at least another couple of inches of inside diameter to be cleared by the inside of the wheel. Even on the naturally aspirated model the rear disks are 13.8 inches in diameter, making the low-budget 17-inch entry-level rims a tight fit.
Standard Fitment Tires and Equivalents
The outside diameter of the stock tires is about an inch smaller than the Range Rover III, at about 28.7 inches instead of 30. Readily available standard fitment tires for the Sport include the following -- I found most of them at The Tire Rack. (The new Continental tires do not yet seem to be present on the tire maker's website).
Continental 4x4 Contact
Hankook Dynapro AS RH03
Yokohama Geolandar H/T-S G051
Goodyear Wrangler HP All-Weather (outside North America)
A wide variety of brands are now available in this size; a recent Tire Rack search gave 38 results.

Bill Welsh reports "I just took delivery of a RRS S/C that came with Continental Sport Contact 270/40R20 tires, which are strictly a summer tire. I live the the Colorado mountains and these tires are a disaster in snow. Just changed them out to Hankook Ventus RH06 275/40R20 with a M+S rating and frankly they are quieter than the Conti's, handle just as well, have 420 treadwear index vs. 280 for Conti's and do very well in ice and snow...the list price is also cheaper."
Using Range Rover III Tire Sizes on Range Rover Sport
As noted above, the stock tires specified for the Sport are about 1.3 inches smaller in diameter than those for the main Range Rover III model. However the G4 Challenge Sports use Range Rover mud tires. The slightly larger size appears to work fine, but will of course put the speedo slightly off calibration. Also the slightly higher effective gearing will reduce acceleration, so those Sportsters interested in maximum performance will not want to try these tires! Options in the slightly larger Range Rover sizes include the following.
General Grabber AT2 -- a genuine All-Terrain tread, available 4th quarter of 2006.
Nitto Hakkapelita winter tire, available 2006.
265/60R18 (very slightly larger but not enough to notice):
Goodyear Wrangler Silent Armor (a good A/T off road design)
Goodyear Wrangler MT/R mud terrain tire
Goodyear Wrangler HP All Weather
Michelin 4X4 Synchrone
Pirelli Scorpion Zero
Goodyear Wrangler MT/R mud tire (see below) -- readily available in UK, have to be specially imported in US.
Continental Cross Contact UHP
Dunkop Grand Trek ST8000 (see photo above; more aggressive than other stock tires)
Dunkop Grand Trek PT9000
Goodyear Eagle RS-A
Michelin 4X4 Diamaris
Note: Another slightly oversize tire is the 275/55R18 (30.1 inches diameter). Some tires such as the Michelin Cross-Terrain SUV and Yokohama Geolandar ATS are available in this size.

Snow Tires and More Aggressive Alternatives (Stock Outside Diameter)
Ice and Snow:
For the 18 and 19 inch wheels, the Bridgestone Blizzak LM-25 4X4 s available in RR Sport stock sizes. For the 20 inch wheels, the dealer network recommends the Continental Winter Contact 275/40R20. Other choices for ice and snow conditions include the Dunlop Grand Trek WT M3 (pictured at left, courtesy of The Tire Rack). This is available in the 275/40R20 size, and also in 235/60R18 (which has an outside diameter of 29 inches, about right for the Sport). The latter size could be a good choice since, as befits a winter tire, it is narrower than stock, often considered better for slicing through the slush. Also available in the same size are the Bridgestone Blizzak DM Z3 and the Pirelli Scorpion Ice & Snow.
Trek WT M3
Vredestein 4Wtreme, available in
255/55R18 and 255/50R19
Outside North America, the Nokian Hakkapeliitta LT is another option, available in the 275/40R20 size. The Pirelli Scorpion Ice & Snow is also available in that size, although it is considerably less aggressive so may not be as good for other off-road use.
I recently found the Pirelli Scorpion AT, a genuine all-terrain tread pattern that is fairly aggressive, is now available in 235/60R18 which should be suitable for the RR Sport and result in the same outside diameter as stock tires. Another genuine all-terrain tread that recently became available is the 255/55R18 Nitto Terra Grappler -- also very close to the correct OD for the Sport. If you can get hold of the 17 inch rims, more options open up including the Bridgestone Dueler A/T Revo 255/65R17. The new General AT2 -- a genuine aggressive all-terrain tread -- is available in RR Sport sizes in the UK but not in the US. In the fall of 2006 it will be available in the US in the Range Rover size -- 255/60R18, about an inch larger than RR Sport size but should work fine.
The Range Rover Sports used in the 2006 G4 Challenge have Goodyear MT/R mud tires originally made for the Range Rover III. These are available in the 255/55R19 size. Note this size is slightly over stock for the Sport, but seems to work fine. They are only "Q" speed rated so you should be careful not to cruise over 100MPH! Until recently, North American owners had to order them from British suppliers such as Bronco 4x4 or BlackCircles.com. who would agree to ship them overseas. In August 2008 they finally became available in the US, and can be ordered directly from The Tire Rack.
Mike Heaivilin of Nevada got them for his Sport. He reports "They did give me about another inch of clearance because it is a taller tire than what comes standard on the sport. They are no clearance issues at all.. they only thing is you have to get used the extra road noise caused by the the thick tire tread, mostly wind noise.. but when off-road the tires perform flawlessly."

17 inch rims:
If you can get hold of a set of the "entry level" 17-inch wheels for the Range Rover Sport (or get some off a D3/LR3), a lot of options open up for oversized and more aggressive tires. For reference, the stock tires are about 28.7 inches in diameter.
The 265/70R17 size (about 31.7 inches in diameter) is available in many brands including the BF Goodrich All-Terrain T/A, Pireeli Scorpion A/T, the Bridgestone Dueler A/T D693, the newer Dueler A/T Revo design, the Yokohama Geolandar ATII, and the new Goodyear Wrangler Silent Armor.
275/65R17 (about 31.2 inches diameter): The new Sumitomo HTR Sport A/T and the Yokohama Geolandar AT are available in this size, which should work without much of a clearance problem.
Other 17 inch sizes that might work include 235/75, 245/70, 255/70, and 265/70. The Bridgestone A/T Revo mentioned above is available in all of these sizes.
18 inch rims: (Note if you
don't have any, you can use stock Discovery 3
/ LR3 rims)
275/60R18: The Yokohama
Geolandar ATS is available in this size.

285/60R18 (31.4 inches
diameter) should work; the Sumitomo HTR Sport A/T is one choice in this
size. Another is the Nitto Terra
Grappler, a true all-terrain design that is reasonably aggressive.
It is about 2 inches larger in diameter than
stock, and about an inch wider. Jeffrey of Santa Barbara is the pioneer
in successfully trying these tires on his RR Sport (see photos at right
Jeffrey replaced the stock wheels with a set of LR3 18 inch wheels,
hiim to choose from the various 18 inch sizes available. He reports
that although the tires certainly fill up the wheel wells, he has had
no clearance issues. To fit the spare in the
stock position in the underwell, he did have to remove the plastic
shield around it, and reduce the pressure to 20 psi to squeeze it in
(he sensibly carries a compressor). Due to the extra width of the tire,
it hangs slightly lower and is a little more visible.
this tire at Tires-easy.com for only $157. (Incidentally I have found they
seem to carry a much wider variety of brands and designs in our Range
Rover sizes than any other online source I have found). Note that it is
also available in the smaller 255/55R18
as mentioned above, which is close to the stock RR Sport diameter.

275/65R18 (32 inch OD) is
another possibility; tires available in this size include the Goodyear
AT/S and the new Cooper STT mud tire. Michael
Quinn of Australia uses the latter on his Range Rover III in
Australia -- but reports having to do a few mods to the inner plastic liners of the guards.
possibility but no aggressive tires seem to be readily available.
19 & 20 inch Rims:
For the 19 inch rims, vanishingly few oversize tires of any tread pattern are available. For the 20 inch rims, Oversized "sport truck" type tires are available in 275/45, 275/50, and 275/55 sizes. However, options that are both aggressive and oversize are almost non-existent.
