No Longer Second Guess Wheel Measurements for Your Custom Build Needs
Much like wiring, measuring for proper wheel and tire fitment is considered a stressful adventure in the automotive hobby. It’s nothing for most enthusiasts to bolt on some performance go-fast bits, or even weld up an exhaust system, but when it comes to figuring out what wheel dimensions will work (or that aforementioned wiring) all bets are off and the second guessing starts in earnest.
Sure, some will throw a spare wheel that is lying around the shop on the car and check fitment, or even borrow a wheel from a friend. Still others will ask total strangers on social media what “should” fit and hope they’re correct. Why not take the stress and inaccurate guesswork out of your wheel and tire fitment with our new WheelWise® wheel fitment tool on your next project?
Accurate Wheel Measurements in Minutes with The Tire Sizes You Plan to Use
Confirming your wheel specs, including backspacing and offset, to order new or custom wheels can be accomplished in no time with our WheelWise® wheel backspacing tool. Simply assemble the WheelWise® wheel fitment calculator tool extensions inside the tire you plan to run and secure the sidewall clamps. Bolt the hub mounting plate to the extensions and you’re ready to mount your tire and take some measurements with our WheelWise® wheel offset measuring tool! It’s that easy!
Our WheelWise® wheel fitment tool is made from 10 gauge steel and laser etched with pertinent measurement points. The wheel offset tool is much sturdier than plastic models that have been on the market (that don’t use an actual tire) and is a much better value than the cast aluminum models as well with precise wheel bolt pattern mounting options in the most popular six-lug bolt patterns using 14mm wheel studs. These specific wheel bolt patterns and stud hole sizes create a much more accurate mounting versus universal slots that inject slop into your fitment check.
Everything you need is included in the WheelWise® wheel fitment tool kit to measure for 14 to 20 inch wheel diameters from 7 to 17 inches wide! Just supply the front and rear tire sizes you will be using, assemble and mount the tool with tire secured to your axle flange or front hub. Once secured with at least two wheel lug nuts or lug bolts you can check for frame and suspension clearance by cycling your suspension up and down with a floor jack (unbolting or removing your shocks/coilovers may make this easier). Turning your front wheels from lock-to-lock will confirm steering angle changes will not create tire to frame/sheetmetal interference as well. Easily loosen the wing nuts and adjust the tool’s backspacing for optimal tire clearance and then lock the adjustment down. Remove the WheelWise® wheel backspacing tool and measure your final backspacing needs to order your new or custom wheels.
NEW! Expand your wheel fitment tool with additional lug mounting plate options!
We have launched additional lug pattern mounting plates to expand the tool’s ability to test fit tire combinations onto just about anything. From modern six-lug trucks to five-lug metric imports and classic five-lug SAE bolt patterns, our additional lug plates will help you with just about any vehicle’s wheel fitment needs. No other wheel and tire simulator offers you more flexibility and durability for the value than our WheelWise® wheel fitment tool.
