Check a different size against this vehicle
Type any tire size below; we'll compute its overall-diameter delta against the OEM 285/60R20 and verdict using the ETRTO ±3% rule.
Common upgrade paths
- Plus-1: 265/60R21; one rim size up, 0.16% OD change. Sharper steering, mild ride penalty, modest cost premium.
- Plus-2: 265/55R22; 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 2026 ram 2500
The 2026 Ram 2500 ships from the factory on 285/60R20 tires mounted on R20 wheels. 4 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 Ram 2500 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 2026 Ram 2500 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 2026 Ram 2500, 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 TIRE PRESSURE SENSOR WILL NOT GO OFF AND KEEPS BLINKING "LOW TIRE PRESSURE. I HAVE MADE SEVEN ATTEMPTS TO GET THIS RESOLVED. I WAS TOLD BY THE DEALER I BOUGHT THE TRUCK FROM LAST NIGHT THAT THERE IS NO MORE HE CAN DO. THEY OVER INFLATED THE TIRES TO 80 PSI TO MAKE THE SENSOR GO OFF BUT THE TIRES ARE ONLY RATED FOR 65PSI MAX. THIS OVER INFLATION HAD VOIDED THE TIRE WARRANTY FROM THE TIRE MANUFACTURER. THIS COULD ALSO RESULT IN A TIRE BLOW OUT AND ACCIDENT WHICH COULD CAUSE DEATH TO ME, MY FAMILY OR PASSENGERS. I NEED TO KNOW HOW TO GET THIS PROBLEM RESOLVED BEFORE ANYONE GETS HUT OR KILLED.
TPMS DOES NOT ALLOW SETTING TIRE PRESSURES TO EITHER THE OEM DOOR STICKER SETTING NOR THE RECOMMENDED TIRE SETTING FROM THE TIRE MANUFACTURER WITHOUT SETTING WARNING LIGHT AND NAG SCREEN ON STARTUP. CONSTANT WARNING LIGHT AND NAG SCREEN CORRECTION WILL LEAD TO DRIVER COMPLACENCY, NEGATING THE PURPOSE OF TPMS ALERTING THE DRIVER TO A POTENTIAL PROBLEM WITH THE TIRES. TPMS REQUIRED OVERINFLATION RESULTS IN POTENTIAL LOSS OF VEHICLE CONTROL DUE TO LOSS OF TRACTION. ABNORMAL TIRE WEAR DUE TO TIRE OVERINFLATION INCREASES RISK OF HYDROPLANING AND LOSS OF CONTROL OF VEHICLE. RAM CUSTOMER SERVICE HAS BEEN CONTACTED AND CONFIRMED THAT THIS PROBLEM IS SYSTEMIC, BY DESIGN, AND CAN NOT BE CORRECTED AT PRESENT TIME. POTENTIAL FIX IS TO REPROGRAM BCM, ALLOWING DEALERS TO RESET TPMS TO APPROPRIATE SETTING FOR TIRES AND ACTUAL LOAD WITH APPROPRIATE DOCUMENTATION.
DRIVING DOWN THE I-10 EAST OF JUNCTION I FELT A SLIGHT VIBRATION AND ATTEMPTED TO PULL OVER AND AS I WAS DOING SO THE PASSENGER REAR TIRE BLEW OUT AND BENT IN THE FENDER BED OF MY TRUCK AND BROKE THE STABILIZER BAR FOR THE BED SKIN. THE TREAD SEPARATED FROM THE SIDE WALL. THERE WAS NO TREAD LEFT ON THE TIRE, ONLY SIDEWALLS. I REMOVED THE TIRE AND PUT ON THE SPARE TO GET HOME. WENT TO DISCOUNT TIRE THE NEXT DAY AND FOUND OUT THERE WAS A RECALL ON THE SAME TIRE BUT DIFFERENT SIZE. THEY REPLACED THE TIRE WITH A NEW ONE AND FILED A CLAIM WITH KUMHO AND SENT THE DEFECTED TIRE TO THEM.
PATRIOT AT LT 285/60R20 TIRES 15,XXX MILES ON FOUR BRAND NEW TIRES, SUDDEN VIOLENT VIBRATION OCCURRED, STOPPED VEHICLE AND FOUND FRONT LEFT TIRE HAD BULGE IN TREAD AND WAS SEPARATING. TWO DAYS LATER SAME THING AND FOUND RIGHT REAR TIRE IN SAME CONDITION. ALL TIRES HAVE CODE DOT TBF2 FA5C 2318 2014 RAM 2500
