Check a different size against this vehicle
Type any tire size below; we'll compute its overall-diameter delta against the OEM 245/75R17 and verdict using the ETRTO ±3% rule.
Common upgrade paths
- Plus-1: 245/70R18; one rim size up, 0.11% OD change. Sharper steering, mild ride penalty, modest cost premium.
- Plus-2: 265/60R19; two rim sizes up, 0.16% 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 2018 jeep wrangler
The 2018 Jeep Wrangler ships from the factory on 245/75R17 tires mounted on R17 wheels. 2 approved fitments are documented for this model year, allowing some flexibility between performance, comfort, and winter compounds. The Compatible alternative sizes table above lists every safe substitution within the ETRTO ±3% overall-diameter tolerance.
Tire choice on the Jeep Wrangler 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 2018 Jeep Wrangler 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 2018 Jeep Wrangler, 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.

AFTER DRIVING A SHORT DISTANCE AND PARKING, I RETURNED TO FIND ONE TIRE FLAT. I CHANGED THE TIRE AND RETURNED HOME. THE FOLLOWING MORNING I CHECKED THE DAMAGED TIRE AND FOUND THE VALVE STEM MISSING. I DROVE TO A SERVICE CENTER AND HAD THE TIRE REMOVED. THE STEM (WITH SPEED SENSOR ATTACHED) WAS LOOSE INSIDE THE TIRE. WE CHECKED THE REMAINING THREE WHEELS AND FOUND ALL WHEELS HAD BADLY CORRODED STEM NUTS, AND THAT ONE OF THE NUTS WAS CRACKED INTO THREE PIECES. REMOVING ALL STEM NUTS DAMAGED THE SENSORS AND ALL HAD TO BE REPLACED. THE "NEW" PARTS ARE ALL OF THE SAME MATERIALS AS THE ORIGINAL ITEMS, THUS I WILL HAVE TO REPLACE THE SENSORS, STEMS, AND STEM NUTS EVERY 2-3 YEARS UNLESS A FIX IS INITIATED.
WHILE TRAVELING ON HIGHWAY VALVE STEM FELL INTO RIM THIS,I BELIEVE WAS CAUSED DO THE FACT THE STEEL RIM HAS A LIP THAT HOLDS WATER IF THE VALVE STEM IS IN THE SIX O CLOCK POSITION IT SITS IN WATER /THE ONLY WAY THE WATER CAN BE REMOVED IS BY THE RIM TURNING,THE RIM IS STEEL,THE STEM IS ALUMINUM THE LOCK NUT IS ALUMINUM ALL OF THESE DIFFERENT METALS MIXED WITH WATER CREATES A CORROSION (ELECTROLASIS) PROBLEM INSIDE THE RIM THE VALVE STEM CONNECTS TO THE TPMS SENSOR ON OTHER MODEL JEEPS THE VALVE STEM IS RUBBER IT SEEMS TO ELIMINATE THE CORROSION PROBLEM I CALLED JEEP CASE#25386092 OFFERED NO RESULTS. UPDATED 4/24/15
I WAS DRIVING ON THE HIGHWAY AT 55 MPH AND MY LEFT REAR TIRE EXPERIENCED A SUDDEN LOSS OF AIR PRESSURE AND THE SIDEWALL BLOW OUT. THERE IS NO VISIBLE HOLES IN TREAD. TREAD RECENTLY PASSED STATE INSPECTION. I HAVE A SPECIAL ORDER TIRE 35X12.5 15LT. THESE ARE BF ALL TERRAN T/A TIRES.
I PURCHASED A 2013 JEEP WRANGLER FROM TALLAHASSEE DODGE CHRYSLER JEEP IN TALLAHASSEE, FL WITH 8+ YEAR OLD TIRES. THEY ARE DRY ROTTED. I HAVE ORDERED NEW TIRES BUT I KNOW THE DOT SAYS TIRES SHOULD NOT BE ON THE ROAD AFTER 5 YEARS. I HAD AN ACCIDENT BECAUSE OF THE TIRES I AM THANKFUL I DID NOT HURT ANYONE ELSE.
