Your cart is empty.The tool comes complete with 1/4-20 carriage bolts and wing nut hardware to provide quick, tool-free adjustments. The kit includes all the tools needed to measure 14 to 20 inch wheel diameters (7 to 17 inches wide), making it easy to use and suitable for all levels of automotive enthusiasts. The wheel fitment tool supports 5-wheel metric wheel bolt patterns in seven of the most popular fitment patterns including 5x100, 5x105, 5x108, 5x110, 5x112, 5x115, and 5x120 patterns for a wide variety of custom applications.

Having spent many years in the custom wheel & tire business, I can't begin to tell you how useful something like this can be. Having the ability to mock up an actual tire and adjust the wheel with and offset before actually ordering a wheel is fantastic. Unfortunately this needs a little better execution. First off, there are no assembly instructions. I was able to use the picture in the ad to figure it out. I had some trouble getting the bolts to fit. The powdercoating added enough that the bolts did not easily fit through some of the holes. Primarily the holes where you bolt the wheel face to the extenders. And I don't understand why the extenders have square holes. In the face that bolts to the wheel hub, the holes are square to retain the carriage bolt heads. But on the extenders you're literally putting a round peg in a square hole. And those holes are smaller (.225" vs .26") so it's not like you could mount the carriage bolts in reverse.There are several 5 lug bolt patterns that this will accomodate. It would not have been hard to accomodate 2 very common ones that are ommitted though. Many domestic and Japanese cars use a 5x4.5" bolt pattern. 4.5" is 114.3mm so if this does 115mm it will probably work as is. Likewise GM typically uses 5x4.75", which is 120.65mm, so the 120mm hole set will probably work with minor modification. IMO this could have easily been done by the manufacturer. Probably the biggest ommision here is the inability to expand it wider than 10". OK, I'd dating myself, but when I was young a 10" wheel was considered very wide. Now there are many cars that come with wider wheels from the factory. And those are the cars most likely to purchase custom made wheels. This should probably be made to expand to 13 or 14" wide, at least.

I have been trying out a bunch of different wheel sizing jigs and had higher hopes for this one. For starters it didn't come with any instructions for assembly and using the tool. I was able to get it assembled by looking at the photos in the product listing but nothing on using it. Based on the parts and way it is assembled I am assuming that it's meant to allow you to put an tire on the jig to check for fitment. That is a nice feature but it's the only positive I found with this one. For start starters it doesn't have holes for 5 x 130 so it won;t work on Porsche, as well as some Mercedes and VW's. It also only has measurements marked on it for rim diameter, they are no markings to set the rim width or the ET. So it's going to take a fair amount of a time with a tape measure to get it set up. Also determining the ET or offset is going to take a bunch of measuring and some calculation to determine. Additionally I wasn't impressed with the wing nuts being tightened down over a slot without a washer in between. So this rim sizing tools has a coupe of pluses and a bunch of minus that make it harder to use then I was hoping for.

I may only use this tool a couple times, but it paid for itself the first time. I just bought $3000 worth of wheels and I don't want to run into frame clearance or fender issues. One thing to keep in mind is to allow a little extra room for the tires considering the bulge in the rim. When I ordered the wheels they were exactly as I ordered them and the rims fell exactly where the tool said they would.

We had a great time fitting tires to a 1970 Chevy C-10. That project has moved beyond the tire fitting stage but this would have been a great help.We mounted this on the truck and the tool showed us exactly how the tires fit that we chose. It showed that the fender on one side is actually about 1/2 “closer. That was something that we had to learn the hard way!Using this tool on a C-10 that we have on stands shows the same discrepancy, side to side. The fitment shouldn’t be as critical as the previous C-10, since we do not intend to tuck the tires.I gave this tool 5-stars, having shown its accuracy in a backwards way.
