Check a different size against this vehicle
Type any tire size below; we'll compute its overall-diameter delta against the OEM 185/60R15 and verdict using the ETRTO ±3% rule.
Common upgrade paths
- Plus-1: 165/60R16; one rim size up, 0.23% OD change. Sharper steering, mild ride penalty, modest cost premium.
- Plus-2: 155/55R17; two rim sizes up, -0.12% 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 2004 scion xA
The 2004 Scion xA ships from the factory on 185/60R15 tires mounted on R15 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 Scion xA 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 2004 Scion xA 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 2004 Scion xA, 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.

DT: 2004 TOYOTA SIENNA. THE CONSUMER STATED TWO OF THE ORIGINAL TIRES HAVE SPLIT. THE FRONT PASSENGER AND REAR DRIVER SIDE TIRES WERE THE ONES AFFECTED. HE WOKE UP ONE MORNING AND THE FRONT TIRE WAS FLAT. AFTER TAKING IT OFF THE VEHICLE HE NOTICED A TWO INCH SPLIT BY THE SIDEWALL. THIS WAS ABOUT AN INCH IN THE TREAD DOWN TWO OR THREE INCHES ON THE SIDEWALL. THE REAR TIRE HAD THE SAME SPLIT. WHEN HE NOTICED IT HAD NOT GONE FLAT. TOYOTA MAINTAINED THAT THE CONSUMER RAN OVER SOMETHING. HE HAD TO ORDER AND REPLACE TWO NEW TIRES BY HIMSELF, HE REPLACED BOTH FRONT TIRES. THE SECOND TIRE OCCURRED TWO WEEKS LATER. THESE ARE DUNLOP TIRES.
THE CONTACT CALLED REGARDING A 2006 TOYOTA SCION XA. THE CONTACT STATED THAT WHEN STOPPING THE VEHICLE THE BRAKES WILL LOCK AND THE CAR WOULD SKID. THERE WERE NO WARNING INDICATORS. THIS FAILURE OCCURRED INTERMITTENTLY. THE CONTACT TOOK THE VEHICLE TO THE DEALER,AND THE PROBLEM WAS DIAGNOSED AS HARD BRAKING. THE CONTACT STATED THAT ALL FOUR TIRES WORE OUT AND NEEDED TO BE REPLACED AT 7700 MILES. SHE TOOK THE VEHICLE TO THE DEALER RECENTLY, AND WAS TOLD THAT THE BRAKE PADS CRACKED AND WORN AND NEED TO BE REPLACED.THIS IS DUE TO HEAVY AND HARD BRAKING.
IN JUNE WHILE GETTING OFF THE EXIT TO GO HOME I WAS GOING AT 25 MHP ANF THE CAR STARTED TO VIBRATE AND I TOTALLY LOST CONTROL HITTING THE EXIT SIGN.
