Check a different size against this vehicle
Type any tire size below; we'll compute its overall-diameter delta against the OEM 235/50R17 and verdict using the ETRTO ±3% rule.
Common upgrade paths
- Plus-1: 235/45R18; one rim size up, 0.28% OD change. Sharper steering, mild ride penalty, modest cost premium.
- Plus-2: 205/45R19; two rim sizes up, 0.04% OD change. Noticeable ride penalty, higher pothole risk, meaningful tire-cost premium.
Use the plus-size calculator to evaluate any rim step against the OEM size.
How to choose tires for the 2003 lincoln LS
The 2003 Lincoln LS ships from the factory on 235/50R17 tires mounted on R17 wheels. 5 approved fitments are documented for this model year, allowing some flexibility between performance, comfort, and winter compounds. The Compatible alternative sizes table above lists every safe substitution within the ETRTO ±3% overall-diameter tolerance.
Tire choice on the Lincoln LS comes down to three trade-offs that matter more than brand loyalty: load index (must equal or exceed the OEM number), speed rating (must match or exceed the placard), and UTQG treadwear (higher means longer life, lower usually means stickier rubber). Owners replacing factory tires with the same compound class, for example all-season for all-season, generally see no change in ride characteristics or fuel economy. Switching categories (performance summer to all-season touring, for example) is where the trade-offs show up at the contact patch.
For 2003 Lincoln LS owners considering a plus-size upgrade, the safer option is a Plus-1 step (one rim size up with a 10-point aspect drop and ~10 mm of additional section width). Plus-2 is technically viable on this chassis if the alternative-sizes table lists a Plus-2 candidate within tolerance, but expect a meaningful ride-harshness penalty and a tire-cost premium of 30–60% per tire relative to the OEM fitment. For winter use the recommended pattern is one width step down (e.g. from a 235 to a 225) with the aspect ratio bumped up to preserve overall diameter; narrower tires apply higher contact pressure per square inch on snow, which translates directly into shorter braking distances. The plus-size calculator evaluates any specific rim step against this OEM size.
Before purchasing, verify the tire size on the driver-door placard of your specific 2003 Lincoln LS, since trim levels and option packages can shift the original fitment from what is documented here. The placard reading is the authoritative source per FMVSS 110, and dealers will reference the placard rather than aftermarket catalogs when validating warranty claims.

IN APRIL OF 2000, I PURCHASED A NEW LINCOLN LS, AND I HAVE HAD 2 FIRESTONE TIRES BLOW APART AT THE SEAMS. IN INCIDENT #1, THE TIRE TOTALLY SEPARATED INTO 2 PIECES, AND IN INCIDENT #2, THE TIRE BLEW OUT ON THE INSIDE WALL, CREATING A WHOLE ABOUT 8" IN DIAMETER. AS A STATE HIGHWAY OFFICIAL HERE IN MASSACHUSETTS, I BELIEVE THAT THE FIRESTONE FIREHAWK LH SHOULD BE RECALLED.*AK (TIRESIZE: P235/50R17)
REAR DRIVER'S TIRE SIDEWALL RIPPED AT 15 MPH WITH 100 MILES ON 2005 LINCOLN LS. TIRE - CONTINENTAL CONTITOURING P225/55R16 CV95, DOT #ACT4 465B 1904 PER CONTINENTAL, TIRE MANUFACTURED IN COLUMBUS? ON 19TH WEEK OF 2004 APPEARANCE OF THE STEEL CORD EXPOSED IN SIDEWAY APPEARS VERY THIN. DEALER AGREED TO REPLACE TIRE, BUT HAVEN'T GOTTEN CAR TO DEALER YET. CALL TO CONTINENTAL COMPLAINT CENTER (1800-847-3349) RESULTED IN A STATEMENT THAT THE TIRE WAS NOT KNOWN TO HAVE ANY ISSUES. MY OBVIOUS CONCERN IS THE SAFETY OF THIS TIRE BUT CONTINENTAL SAID THERE IS NO SAFETY ISSUE!!!
MY MICHELIN PILOT SPORT MS TIRE 235/45Z/R17 DEVELOPED A BUBBLE ON THE INSIDE WALL OF THE TIRE AND LEAKED AIR. THE TIRE WAS USED UNDER A NORMAL COMUTING ROUTINE AND NEVER PLACED UNDER ANY UNUSUAL STRESS OR ROAD CONDITIONS. IT COULD NOT BE REPAIRED AND HAD TO BE REPLACED. THIS IS CONSISTENT WITH THE RECALL OF 255/35ZR20 97Y EXTRA LOAD. I BELIEVE THE 235/45Z/R17 SPORT MS IS ALSO DEFECTIVE AS IT HAS THE SAME CHARACTERISTICS. THE OLD TIRE WAS LEFT AT THE TIRE DEALER AND WAS DISPOSED. A LETTER FROM THE DEALER CONFIRMING THIS CONDITION IS POSSIBLE.
OVER THE PAST 13 MONTHS, WE HAD HAD A TOTAL OF SIX VERY LOW OR FLAT TIRES, INCLUDING ONE BLOWOUT ON AN INTERSTATE. NO DEFECTS WERE FOUND IN THE TIRES (PUNCTURES). WITH THE EXCEPTION OF THE BLOWOUT, ALL TIRES WERE ABLE TO BE REINFLATED. WE HAVE BEEN TOLD BY TWO SOURCES (A FORD DEALERSHIP AND A TIRE DEALERSHIP) THAT A KNOWN PROBLEM WITH ALLOY WHEELS CAUSES THE TIRE SEAL TO BREAK. THERE HAVE BEEN NO INJURIES TO-DATE, BUT THE FREQUENCY WITH WHICH THIS IS HAPPENING IS A CONCERN. THE LAST FLAT TIRE OCCURRED YESTERDAY (01/13/2004).
