I got a set of wheels for my 01' f150 they are vision off road maniac.they are unilug,will they fit on my truck,i know bolt patern is 5x135mm, just wondering since they are unilug that does make them fit most trucks, right ?

The unilug pattern is built to be a multi fit wheel and will work with multiple different bolt patterns. They have different styles of unilug as well as some have 10 holes which is designed 5 for Ford and 5 for Chevy patterns. There are also some made that have an oval shaped bolt hole where the studs will go through and attached to the wheel. Also keep in mind that these wheels will require a special lug nut and washer which will generally be harder to find and will cost more as well. The cost for the uni lug bolts and washers will vary from $30 - $50 depending on the brand and quality of the product.
