Diego Zuniga Posted November 18, 2016 Report Share Posted November 18, 2016 Hey guys I am new to Ratsun and you are all a great help and know so much about these great little cars and trucks. I bought a 72 521 this past summer and I love it. Its going in for new floors and some other minor rust repair next week. My question is I was wondering if 2005 to 2016 frontier rims will fit on it or is there any mods needed? 6x114.3. It is still stock suspension on the truck with drums. If they do fit I have a set I want to pick up for it this weekend. Quote Link to comment
tdaaj Posted November 18, 2016 Report Share Posted November 18, 2016 No they will not fit, you need 6x139.7 1 Quote Link to comment
DanielC Posted November 18, 2016 Report Share Posted November 18, 2016 The chassis and body of a 521 is not measured with metric dimensions. The bolt pattern for the wheels of a 521 are 6 on 5 1/2 inches. The lug nuts by the way are a SAE 7/16-20 thread. 1 Quote Link to comment
Lockleaf Posted November 18, 2016 Report Share Posted November 18, 2016 No, the modern 6x114 lug pattern will not fit. Everything up to 05 were all 6x139, the same as Chevy and Toyota 6 lug. Your truck has the 6x139. 1 Quote Link to comment
datzenmike Posted November 19, 2016 Report Share Posted November 19, 2016 Same bolt pattern are Ford, Chev, Mazda, Trooper, Courier, Toyota, .... just about any 6 bolt except DODGE. 1 Quote Link to comment
Diego Zuniga Posted November 19, 2016 Author Report Share Posted November 19, 2016 Thanks for the help guys. Any ideas on what style factory aluminum 5 spoke rims will work on it? I like the Nissan frontier style but if they don't work it don't matter. Was going to post picture of what I like but I cant not figure out how to post pictures. Prefer not to do any modification or minimal 1 Quote Link to comment
Lockleaf Posted November 19, 2016 Report Share Posted November 19, 2016 Nissan Titan rims are a common favorite. But just keep your eyes open as you drive. If you see a 6 lug vehicle with nice looking stock rims, look them up, get specs on them and we can tell you if those will fit without modification. 1 Quote Link to comment
Diego Zuniga Posted November 20, 2016 Author Report Share Posted November 20, 2016 Do the titan wheels bolt right on or are modifications needed? Quote Link to comment

I like the Nissan frontier style but if they don't work it don't matter. Was going to post picture of what I like but I cant not figure out how to post pictures. Prefer not to do any modification or minimal First find out exactly what the offset or back spacing is for the 521 stock rim. This is the relation of center line tire position to the wheel mounting surface (WMS). A rim may hold the center line of the tire inward toward the suspension or positive offset, exactly 50/50 over the WMS or slightly out from the WMS, or negative offset. A rim with too much negative offset can move the tire out from under the vehicle fender where it is exposed to being hit by the body as the suspension moves over bumps. Too much positive offset moves the tire inward and may interfere with suspension or rub when turning. Offset (positive or negative) is measured in mm. (millimeters) For example a -20mm (negative offset) is about 3/4" and moves the entire tire that much away from the vehicle center line possibly interfering with the fender. A 1" wider rim with the same offset adds 1/2" to both sides as measured from the middle Now that you know the 521's offset you can experiment on a different rim selection. Find out the maximum widths and offsets that will work on your truck, rather than liking a rim and trying to make it fit. In a sense it's like selecting a good wife. Your choice must fit, and work or you are doomed to unhappiness.. 1 1 Quote Link to comment
