Check a different size against this vehicle
Type any tire size below; we'll compute its overall-diameter delta against the OEM 215/45R17 and verdict using the ETRTO ±3% rule.
Common upgrade paths
- Plus-1: 185/45R18; one rim size up, -0.26% OD change. Sharper steering, mild ride penalty, modest cost premium.
- Plus-2: 205/35R19; two rim sizes up, 0.13% 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 2007 saturn ion redline
The 2007 Saturn Ion Redline ships from the factory on 215/45R17 tires mounted on R17 wheels. Only one approved fitment is documented for this model year, so replacement options should match the original size exactly unless a plus-size upgrade is being considered. The Compatible alternative sizes table above lists every safe substitution within the ETRTO ±3% overall-diameter tolerance.
Tire choice on the Saturn Ion 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 2007 Saturn Ion Redline 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 2007 Saturn Ion Redline, 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.

WHILE TRAVELING ON AN INTERSTATE HIGHWAY, OBSERVED A SOFT FLAPPING SOUND THAT CAUSED CONCERN. BEFORE I COULD SLOW DOWN OR TAKE ANY ACTION THE LEFT REAR TIRE TREAD SEPARATED FROM THE WHEEL AND THEN THE COMPLETE TIRE WAS EJECTED FROM THE VEHICLE. I WAS ABLE TO EXIT THE ROADWAY AND CALLED THE STATE HIGHWAY PATROL. TO REPORT THE INCIDENT AND REQUEST ROADSIDE ASSISTANCE.
OEM TIRES ON 2004 SATURN ION RED LINE UNSAFE TO USE ON WINTER DRIVING CONDITIONS. HAD TO REPLACE TIRES WITH WINTER RATED ONES. *JB THE CONSUMER EXPERIENCED EXCESSIVE STOPPING DISTANCE WHILE ON SLIPPERY SURFACE. ON ONE OCCASION THE VEHICLE WENT A HALF A BLOCK PAST THE CONSUMER'S TURN WHEN THE ABS ACTIVATED BUT COULDN'T FIND A TIRE WITH ENOUGH TRACTION TO STOP THE VEHICLE. THE CONSUMER FOUND THAT THE OEM TIRES, DUNLOP SP9000, WERE THE CAUSE OF THE EXCESSIVE STOPPING DISTANCE.
IN TWO SEPARATE INCIDENTS WE WERE DRIVING AT SPEEDS OF, 65, AND 55 MPH RESPECTIVELY WHEN WE HEARD A LOUD THUMPING NOISE. THE FIRST TIME ON THE FRONT PASSENGER'S SIDE TIRE AS SOON AS WE PULLED OVER IT BLEW OUT. THE SECOND TIME ON THE FRONT DRIVER'S SIDE TIRE WHEN WE FELT AROUND ON THE INSIDE OF THE TIRE WE COULD FEEL A KNOT ON THE SIDEWALL, WHERE IT WAS ABOUT TO FAIL JUST LIKE THE FIRST.
RECENTLY BOUGHT A NEWER CAR(O3 ION COUP) WAS TOLD THE TIRES WERE NEW AFTER DRIVING ABOUT 5,793 MILES I AM TOLD BY THE DEALER THAT THE TIRE HAVE CHOPP. I AS WELL NOW SEE THEIR IS A RECALL ON THE TIRE LINE NHTSA ID # 01T006000. THEY ARE FIRESTONE TIRES FIRE HAWK GTA-02 205-55R16. THE DEALER TOLD ME THEIR WAS NO HAZARD BUT NOW IM VERY CONCERNED.THE CAR IS NOT RIDING RIGHT. THE DEALER AT THIS POINT IS ONLY WILLING TO REPLACE ONE TIRE. I AS WELL HAVE FILED A CLAIM WITH MY WARRANTY ROAD HAZARD AT 1-800346-6469 CLAIM # 21833283 AS OF 11/07/2007. I HAVE CONTACTED THE DEALER TO TRY AND GET THEM REPLACED UNDER THEIR WARRANTY.
