Am i able to inspect the lug bolt size for my own Kia Optima? The short answer is yes, and it's only you or the installation technician who has this opportunity to identify the correct lug nut size with measuring tape along with the actual physical access to it. There is also a different method - by looking through our charts made up by the pros with attention to all the information. We collect details from the manufacturers' handbooks to demonstrate in a form of practical tables. These charts charts are very helpful if you fail to figure out the lug nut size and thread spacing for your own Kia Optima.

Just in case you would like to re-check our online data, here you have basic process. Start out with a thread size: measure its diameter and pitch with a special gauge that you can buy in a hardware store. Alternatively, just take your thread towards the store and you will be able to whirl it onto bolts. One more problem is figuring out the bolt seat type - the contact area in between the lug nut and wheel surface. The most famous types are mag seating, acorn/tapered seating, and ball seats; however, we have also 2 more: flat seats and ultra tapered mag seats. The next step is to inspect lug nut measurements: total length, exterior diameter, shank depth, and also shank diameter. And the final thing is defining which shade your own Kia Optima bolts and lug nuts are going to be.


Never try to use a metric thread nut on a US standard thread stud or vice versa.
