What is Plus 1 and Plus 2 sizing?

Plus 1 increases wheel diameter by 1 inch while reducing aspect ratio to maintain the original tire's overall diameter. Plus 2 increases wheel diameter by 2 inches.

What are the benefits of plus sizing?

Shorter, stiffer sidewalls provide sharper steering response, reduced cornering body flex, and enhanced visual appeal.

Automotive Fitment & Safety Advisory

Calculations presented on TireSizeChecker.com are nominal mathematical projections. Actual installed rolling dimensions fluctuate depending on rim width matching, tire manufacturing tolerances (TRA/ETRTO standards), pneumatic inflation pressure, dynamic speed expansion, and vehicle cornering loads.

Always verify mechanical suspension clearance, brake caliper clearance, wheel fender lip clearance, speedometer recalibration, and load/speed ratings with a certified tire technician before mounting non-OEM tire sizes.
