Check a different size against this vehicle
Type any tire size below; we'll compute its overall-diameter delta against the OEM 245/75R16 and verdict using the ETRTO ±3% rule.
Common upgrade paths
- Plus-1: 245/70R17; one rim size up, 0.12% OD change. Sharper steering, mild ride penalty, modest cost premium.
- Plus-2: 265/60R18; two rim sizes up, 0.17% 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 1993 GMC suburban 2500-4wd
The 1993 GMC Suburban 2500-4wd ships from the factory on 245/75R16 tires mounted on R16 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 GMC Suburban 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 1993 GMC Suburban 2500-4wd 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 1993 GMC Suburban 2500-4wd, 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.

PULLED OUT OF MY DRIVEWAY GOT UP TO SPEED OF ROADWAY THAT IS 50 MPH FELT A VIBRATION IN THE FRONT END, SLOWED DOWN IT WENT AWAY, SO I STARTED TO SPEED UP AGAIN TO SEE IF IT CAME BACK, THEN BOOM MY FRONT PASSENGER TIRE LITERALLY BLEW UP, THE TREAD SEPARATED AND THE TIRE ALMOST BLEW COMPLETELY OFF THE RIM. I TEMPORARILY LOST CONTROL OF THE VEHICLE AND SKIDDED TO HALT ON THE SIDE OF THE ROAD TEARING UP A LAWN AND ALMOST TAKING OUT A GUARD RAIL. THE TIRE BENT MY FRONT BUMPER AND RIPPED MY RUNNING BOARD PARTWAY OFF. I AM VERY LUCKY NO OTHER TRAFFIC WAS AROUND ME... I CHANGED THE TIRE TO MY SPARE AND AM NOW IN THE PROCESS OF REMOVING THE REST OF THE CORNERSTONES FORME MY TRUCK, IT'S NOT WORTH THE RISK
ON FEBRUARY 3, I TOOK DELIVERY OF AN 1999 SUBURBAN. THE REAR DRIVER'S TIRE HAS 5 PUNCTURED HOLES. BOTH THE FIRESTONE DEALER, AND THE GM CUSTOMER SERVICES REPRESENTATIVE CONFIRMED THAT THIS TIRE IS NOT OFFERED TO THE PUBLIC; FIRESTONE IS SELLING IT ONLY TO GM FOR PRODUCTION. I HAVE MADE PHONE CALLS AND SENT FAXES TO GM. GM HAS NOT SECURED A TIRE. THIS MONOPOLISTIC PRACTICE THREATENS THE SAFETY OF THE PUBLIC. THE TIRE SHOULD BE AVAILABLE TO THE PUBLIC. *AK( DOT NUMBER: TIRE SIZE: 245/75R16 )
WHEN MAKING ANY KIND OF TURN BETWEEN 90 DEGREES OR SMALLER THE FRONT WHEELS LOCK UP. DEALER STATED THAT THIS WAS NORMAL CONDITION WHEN DRIVING IN 4- WHEEL DRIVE. OWNER WAS DRIVING IN 2- WHEEL DRIVE AT THE TIME. THE SUBURBAN IS BEING REPAIRED BY DEALERSHIP. STEERING REPAIRED, BUT VEHICLE STILL VIBRATES WHILE DRIVING ON HIGHWAY, DEALER SAYS THAT IT IS BECAUSE TIRES NEED TO BE REPLACED. OWNER BELIEVES TIRES SHOULD LAST LONGER THAN 21,000 MILES.
265/70/R16. Cruising down Interstate around Des Moines, Iowa at 65 mph. Hot day July 2021. Heard muffled "pop" noise. Few seconds later, suburban began to shake and vibrate violently. Approaching uncontrollable. Pulled off road onto side street. Noted bulge on top of tire. Located a Goodyear tire store in Ames, Iowa. Tire man identified the problem, ordered a new tire (Hankook brand). We spent unintended night nearby in hotel, had tire changed out at Goodyear Tire store, all other tires were inspected by qualified technicians, given a clean bill of health, and we continued on. No warning of impending tire failure. This incident was a second belt failure on same brand of tire within 30 days. First belt failure occurred about 20 days earlier on a same brand, and type tire that had less than 1,000 miles of wear on same vehicle.
