Before submitting a technical support ticket, check if your inquiry is covered by our instant self-service fitment resources:
Will 33" or 35" tires rub on my stock truck?
We maintain comprehensive vehicle fitment guides for America's most popular truck and SUV platforms. Check our dedicated clearance guides before ordering tires:
Why does my physical tire measure different than the calculator?
Our calculators compute true nominal geometric dimensions based on Tire and Rim Association (TRA) engineering standards. However, physical tire dimensions vary depending on: (1) rim width—mounting on an 8" rim vs a 10" rim changes section width by approx. 0.2" per 0.5" rim difference; (2) tread depth and aggressive sidewall lugs; and (3) cold inflation pressure.
How do I report a calculation discrepancy or submit a vehicle correction?
We take calculation accuracy extremely seriously. If you discover a discrepancy between our calculator output and an OEM tire manufacturer spec sheet, please email info@tiretoinches.com with the exact tire brand, model, rim width, and measured dimensions so our engineering team can audit the formula.
