How to choose tires for the 1989 geo metro
The 1989 Geo Metro ships from the factory on the original equipment size tires mounted on the factory rim 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 Geo Metro 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 1989 Geo Metro 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 1989 Geo Metro, 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 owners' own words
Verbatim excerpts from complaints filed with NHTSA about Geo Metro. Reports are published by NHTSA as filed and are lightly cleaned here only to remove intake codes.
THE PROBLEM WITH THE WINDOW WAS REPORTED YESTERDAY 11/12/1999. I FORGOT TO ADD THAT IT MAY NOT CAUSE SAFETY PROBLEMS NOW BUT MONTHS DOWN THE LINE AND DEPENDING ON THE TEMPERATURES, THE SEEPAGE OF THE SEALANT CAN CAUSE THE SEAL AROUND THE WINDOW TO BE INEFFECTIVE AND ULTIMATELY CAUSE WATER TO ENTER THROUGH THE CABIN AREA. WHEN THAT HAPPENS IT COULD CAUSE SHORTAGE AND RISK TO MAJOR COMPONENTS. THE PROBLEM WITH THE TIRES ARE THAT THEY SHOWED PRE-MATURE UNEVEN WEARING ON THE OUTER TREADS OF ALL TIRES AT APPROXIMATELY 1,500 MILES. THIS WEARING CAN BE HAZARDOUS DURING WET DRIVING CONDITIONS AS THE GRIP OF THE TIRES TO ADHERED TO THE ROAD CAN BE LIMITED. I REPORTED 3 TIRES/FAILURES BECAUSE I HAD TO REPLACE ONE ORIGINAL BECAUSE OF A FLAT THAT WAS UNREPAIRABLE.
THE GOODYEAR INVICTA GL 155-80-13 TIRES ON THE VEHICLE REQUIRED REPLACEMENT, VEHICLE EXPERIENCED A FLAT TIRE ON ONE, TIRE HAD A FIST SIZED BUBBLE ON THE SIDEWALL, INSPECTION SHOWED REMAINING TIRES WERE ALSO DEFECTIVE, CONSUMER REQUESTING REIMBURSEMENT DUE TO DEFECT TIRES. *MJS
ONE OF THE WHEEL HUB CAPS CAME OFF AND THE TREAD OF TWO TIRES BEGAN PEELING OFF.*NM A TICKING SOUND WAS HEARD WHILE THE VEHICLE WAS BEING DRIVEN AND GETTING LOUDER EVERY DAY. THE TRANSMISSION FLUID APPEARED BROWN INSTEAD OF PINK. THE VEHICLE WAS LEAKING OIL. THE SPARK PLUGS WERE WORN OUT. THE DISTRIBUTOR CAP CRACKED, THE OIL SWITCH WAS BAD, AND THE PCV VALVE WAS BAD. THE ENGINE WAS REPLACED. THE ENGINE STALLED WHEN THE VEHICLE REACHEED THE 25 MPH MARK. NO CHECK ENGINE LIGHT COMES ON. THE VEHICLE WILL NOT RESTART.
DT*: THE CONTACT STATED THAT WHILE DRIVING 75 MPH THE PASSENGER FRONT TIRE BLEW OUT. THE SERVICE DEALER FOUND AIR COMING OUT BETWEEN THE VALVE STEM AND THE TIRE. AFTER TEN DAYS, THE DRIVER SIDE FRONT TIRE BLEW OUT WHILE DRIVING 50 MPH. THE SERVICE DEALER FOUND AIR COMING OUT IN THE SAME AREA. THERE WERE NO ACCIDENTS PRIOR TO THESE INCIDENTS. THE PROPER PRESSURE RECOMMENDED BY THE MANUFACTURER WAS UNKNOWN AND PRESSURE CHECKS WERE NOT PERFORMED. THERE WAS ALSO NO VIBRATION BEFORE THE INCIDENT. HE BRAND NAME OF THE TIRE IS TURISMO TWO.
