Check a different size against this vehicle
Type any tire size below; we'll compute its overall-diameter delta against the OEM 245/70R16 and verdict using the ETRTO ±3% rule.
Common upgrade paths
- Plus-1: 265/60R17; one rim size up, 0.05% OD change. Sharper steering, mild ride penalty, modest cost premium.
- Plus-2: 225/65R18; 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 1993 isuzu trooper RS
The 1993 Isuzu Trooper RS ships from the factory on 245/70R16 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 Isuzu Trooper 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 Isuzu Trooper RS 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 Isuzu Trooper RS, 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.

THE CONTACT OWNS A 2002 ISUZU TROOPER EQUIPPED WITH BF GOODRICH MUD TERRAIN T/A KM2 TIRES, SIZE: LT265/75R16. WHILE DRIVING BETWEEN 55-65 MPH, THREE OF THE TIRES EXPERIENCED TREAD SEPARATION. THERE WERE MOMENTARY VIBRATIONS JUST BEFORE THE FAILURES. THE FAILURES OCCURRED ON THREE OCCASIONS. THE VEHICLE WAS TAKEN TO A TIRE DEALER WHERE THE FRONT DRIVER SIDE AND REAR DRIVER AND PASSENGER SIDE TIRES WERE DEEMED DEFECTIVE. THE TIRES WERE REPLACED. THE DEFECTIVE TIRES WERE REPLACEMENT TIRES WITH ONLY 12,000 MILES ON THEM PRIOR TO THE FAILURES. THE VEHICLE FAILURE MILEAGE WAS 49,000 AND THE TIRE FAILURE MILEAGE WAS 12,000. THE VIN AND DOT NUMBER WERE NOT AVAILABLE.

NOW I HAVE TO PAY FOR A NEW SET OF TIRES. THIS PROBLEM IS MORE WIDESPREAD THAN BRIDGESTONE LEADS THE PUBLIC TO THINK! PLEASE HELP!!( DOT NUMBER: EJMT TIRE SIZE: P24570R16 )
THE RECENT DEATHS OF 62 PEOPLE DRIVING THE FIRESTONE 15" TIRES SHOULD ALSO RAISE THE CONCERN THAT THE WILDERNESS 16" TIRES HAVE THE SAME DEFECTS AND WILL EXPLOSE. MINE DID.

MY PHONE NUMBER IS (318) 377-2797 IF YOU HAVE ANY FURTHER QUESTIONS. THANK YOU.( DOT NUMBER: TIRE SIZE: 255 70 R16 )
