Definitely worth a couple of bucks to have it in my pocket. Just missing two obvious features: app should allow saving of wheel/tire configurations (or at least retain the current settings when exiting the app), and in the size predictor it should list tires of the same rim diameter (after all, many people plus size just the tire width w/o going to larger rims and predicting a wider tire with similar revs per mile would be useful). ### 5/5 — Great app! *2010-01-12* I'm so glad "there's an app for that" with wheel and tire calculations. Anyone who is changing the wheels they owe it to themselves to get this app. It will make fitting a lot easier. Great app! ### 5/5 — Nice tool *2010-01-09* I really like the cut-a-way/sectional view, it was exactly what I was looking for. I swap tires and wheels a lot, this tool has everything that I need. ### 5/5 — Wow! *2010-01-08* I had no idea there was so many calculations needed when changing the wheels on your vehicle. This app not only does the math for you, it uses very nicely done graphical representations. I recommend this application to anyone that is thinking about changing the wheels or tires on their car or truck. ### 5/5 — Nice work, does it all *2010-01-07* I just downloaded this app today and I must say it does it all! I love the cut-away view. It displays all the key tire and rim measurements! Additionally, there is a textual report that displays all of this info and more (like effects on the speedometer and appropriate rim sizes for the selected tire). This report also allows you to compare different tires and wheels. Another feature that I like is the tire compatibility report. It displays comparable/compatible tires which will certainly be useful in the shop. Finally this app provides a nice tehnical reference that displays things like traction, treadware, temp codes. ## Most critical reviews (10 lowest-rated) ### 1/5 — App stop working… *2023-11-19* Since last IOS update this app has not worked. Please fix. **Developer response:** Please contact support if you are having an issue. We are not seeing any issues with this app as of iOS 17.2. ### 1/5 — Calculations are incorrect *2019-10-05* Calculations are incorrect and not carrying through completely making app look cool but absolutely useless. ### 1/5 — Awful *2019-08-30* Totally doesn’t function. Requesting a refund immediately. ### 1/5 — Dont buy, it does nothing *2019-07-08* App opens on my ipad mini 4, but after loading, it does nothing. I tap and tap, all over the screen, app does not respond, does nothing. Want my money back. ### 1/5 — Rip off *2011-03-29* Paid for it down loaded and it will not open. Four dollars wasted. Can't even go to their web site it will not let me. Don't waste your money!!!!!!!! Gave it one star because it will not let you do any less!!! Don't waste your money!!! No way to contact these people or anything. Four dollars isn't much but nothing for your money isn't right!!!!! ### 2/5 — The app dictates the min / max wheel size?? *2020-04-09* I cannot enter the wheel size I want to suit the tyre I want??? It defaults to a larger wheel size automatically. ### 2/5 — Save your money *2015-06-26* It's not worth $4. Yes it works, but there are better for less. ### 3/5 — Needs More! *2019-07-12* but i just wished that it could include allow more than just 2 wheels, (More than just A and B) I think there should be a C,D,E,F, etc. I also think a cool addition would be to add the ability to adjust camber and a measurement of the tire patch with the camber dialed in or have thw function of calculating how the wheel will gain positive camber when cornering and giving the measurement of that tire patch at that speed. Of course that would need to have inputs for things like, type of suspension, spring rate, ride height, weight, etc. That sounds actually very complex but would be really cool if it were apart of the app. ### 4/5 — the Best Tire/Wheel Calculator *2021-05-18* Please ,, - make it rememberers the last Tire/Wheel Dimensions Best Tire/Wheel App on the App Store **Developer response:** App has been updated to support all iOS platforms and iOS 11+. Thanks for your support! ### 4/5 — TireLab *2013-01-15* This is an amazing app! It's just what I've been looking for. However, I noticed what appears to be a small discrepancy In the way the graphs portray sidewall height or sidewall. In the reference area sidewall is described as the section between the tire bead and the tread. In the graph area, sidewall is shown to be the section between the tire tread and the lip of the wheel. This would give the illusion that the visible sidewall height is actually larger than it really is. Typically the flange or bead seat of the wheel which holds the bead of the tire, protrudes from the barrel approximately 1 inch or about 25 mm. The graphs show all of this of course but the measured distance for sidewall height is shown incorrectly. Other than this I really like this app ## Most praised reviews (10 highest-rated) ### 5/5 — Excellent App for Tire shop! *2026-05-25* This app is amazing !!! Helps a lot with explaining customers on tire sizes and how it will effect their braking and suspension when purchasing new wheels and tires specially if they aren’t OEM sizes! ### 5/5 — Excellent *2026-05-01* Works great. I wanted new wheels for my truck, but wanted them to be about 5/8”-1” inside the fender flares. The factory wheels were offset so far in, the truck looked like it was wearing roller skates! I didn’t want them sticking out too far, and didn’t like the factory tucked in offset. This helped with find the perfect fit. The wheels ended up being exactly where I wanted them! Thank you! ### 5/5 — Great *2013-01-31* Love this one, would like to see it full screen on my iPhone 5 but not really needed it works great. Thanks for this. ### 5/5 — ????? What happened *2011-03-29* This is an awesome app !! 4 stars only thing is After updating my phone to 4.3 this app will not open at all I tried deleting it and reinstalling it but no luck. I love this app please fix this problem. ### 5/5 — Nice app works great ! *2011-02-27* ^^ ### 5/5 — Mr *2011-02-07* This the best of this product and the author is prepared to make changes An excellent product ### 5/5 — Slick! *2010-04-12* Finally a tire app that provides useful info and diagrams! The app allows you to actually see and compare different tire and wheel specs. Slick! ### 5/5 — Lifesaver *2010-04-07* This app is a true lifesaver! I used it to determine the exact offset required for my vehicle when I went from a 20"x9.5" rim to a 20"x13" rim. The calculations it provided me were dead on. It also helped me determine the exact aspect ratio required. It was a complete success as the tires and wheels are now on my vehicle and they fit perfectly and the speedometer error is exactly what this software predicted! I'm giving this app a 5 star rating because no other app even comes close to this one. Saved me lots of time and money (had I purchased an incorrect tire/wheel combination). ### 5/5 — Yes! *2010-02-09* This is the tire calculator that you need. It is the ONLY tire/rim calculator available on the app store that does everything you need! Thank you, this is exactly what I have been looking for! ### 5/5 — Nice app, easy to use *2010-01-13* The functionality offered by this app is great but what I really appreciate is the ease of use. I was able to be productive from the initial launch. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
