Look up a vehicle's manufacturer-reported trim, year, make, model, and available truck specs with NHTSA vPIC. Treat the result as a clue, not a complete build sheet or fitment guarantee.
Look for a manufacturer window sticker or view vehicle specifications reported through NHTSA vPIC. Missing fields are marked, not inferred.
Compare OEM tire dimensions vs oversized truck tires. Calculates overall diameter, section width, revs per mile, ground clearance delta, and speedometer error percentage.
Calculate inner suspension clearance change and outer fender poke when swapping factory wheel width and offset (+44mm to negative offset).
Enter hub-to-fender measurements to calculate exact factory rake in inches and determine the optimal spacer/strut lift height without reverse rake.
Calculate proper cold tire PSI when switching between P-metric standard load tires and LT Load Range E 10-ply tires using TRA load-inflation tables.
Look up truck bolt patterns (e.g. 6x139.7, 6x135, 8x180, 8x170), center bore, lug thread pitch, and factory dry lug torque specs.
What trim is my truck? Start with the 17-character VIN decoder. It may return a manufacturer-reported Trim / Series value and other available specifications; use that result to narrow the search, then check the door or door-jamb tire label, owner's manual, installed wheel and tire, and the part maker's application notes. Can you check tire size by VIN number? Treat the decoder as one clue and confirm the tire label and application notes before buying.
