maddmark1981 Posted October 24, 2015 Share Posted October 24, 2015 What are common basic upgrades from stock 235/75 to 31x10.5R15? Any insight is appreciated Sent from my MotoG3 using Tapatalk Link to comment Share on other sites More sharing options...
Jmoor85 Posted October 24, 2015 Share Posted October 24, 2015 From what I have read on here the 31x10.5R15 came stock on some pathfinders so you shouldn't have clearance issues. Depends on how saggy your stock suspension is. I have the same tire and wheel combo as you and will be buying 15x8 wheels for my 31x10.5R15 tires since those wheels you have are only 6" wide and while you can get those larger tires on those wheels it will cause faster wear and in even wear due to the bead getting pulled so far in which will push the center of your tire tread up and cause quick wear and tear. 1 Link to comment Share on other sites More sharing options...
maddmark1981 Posted October 25, 2015 Author Share Posted October 25, 2015 would 15x 10.5 work for rims? Link to comment Share on other sites More sharing options...
maddmark1981 Posted October 25, 2015 Author Share Posted October 25, 2015 I am looking at second hand rims and I see a lot of 6 bolt 15x8 off of chevys, will they fit? Link to comment Share on other sites More sharing options...
PathyAndTheJets Posted October 25, 2015 Share Posted October 25, 2015 Yeah, any six lug Chevy rim fits. I want to say the bolt pattern is 6 on 5.5 You'll want a 7 or 8 inch wide rim. 1 Link to comment Share on other sites More sharing options...
Pav Posted October 25, 2015 Share Posted October 25, 2015 If you want Steel rims...just go to the scrappers and find some Nissan Xterra Steel rims. All of their 15 inch were 7J which is all you need. Stick to 7 inches...these trucks already don't have a very good turning radius. 1 Link to comment Share on other sites More sharing options...

maddmark1981 Posted October 25, 2015 Author Share Posted October 25, 2015 So stick to 7 inch Sent from my MotoG3 using Tapatalk Link to comment Share on other sites More sharing options...
adamzan Posted October 25, 2015 Share Posted October 25, 2015 Get a set of legos and call it a day. That's what bushnut posted. Link to comment Share on other sites More sharing options...

Rebelord Posted October 26, 2015 Share Posted October 26, 2015 Watch it with Chevy rims. A lot have smaller hub bore size. If you can find a set of early R50 wheels or Frontier they are 15x7 and aluminum. Otherwise Summit simple $45 each steelies Sent from my SM-G920V using Tapatalk 1 Link to comment Share on other sites More sharing options...
CDN_S4 Posted October 26, 2015 Share Posted October 26, 2015 7 inch is too small! 15x8 is a minimum otherwise you restrict yourself for options in the future. If you ever go to 33's you will want 12.5 wide tires and 8 wide rims is minimum you can go with. Otherwise you will have the pizza cutter wagon wheels look.

Pav Posted October 26, 2015 Share Posted October 26, 2015 He already has a set of 31(s) and trying to do things on a budget. Mags are very cheap second hand if you know how to look. Especially for a 15 inch since most people are running 16 inch now. Finding a 7 or 8 inch isn't difficult. Yeah I agree you will need wider to run 12.5 but that would also require a lot of beefing up of the truck's current condition and lots more investment. 1 Link to comment Share on other sites More sharing options...
maddmark1981 Posted October 26, 2015 Author Share Posted October 26, 2015 Definitely... I'm not ready for big shoes yet, I've only replaced a couple bushings and any bigger than 31 I'm thinking is out of reach for me right now...thanks, I'm getting bites now..

01Pathmaker Posted October 26, 2015 Share Posted October 26, 2015 I've been wrenching for about 2yrs now and never heard of wheel width having an effect on turning radius. The 2 things that contribute to your given turning radius are wheelbase and cramp angle. Certainly such a slight difference won't decrease your turning radius, so that shouldn't even be a second thought. Ideally, if you can find 15x8's with 3.75" backspace, you'll be golden for your 31's as well as any future upgrades to a 12.5 tire. If you're looking at stuff off of a Chevy, you'll want something from an 87 or earlier pickup, or 91 or earlier suburban/blazer/Jimmy (all fullsize of course). 1 Link to comment Share on other sites More sharing options...
adamzan Posted October 27, 2015 Share Posted October 27, 2015 15x8 with 4" backspace works better on the wd21. I bought Cragar Soft 8's from summit racing years ago for like 38 bucks a piece. So cheap I bought 6. 1 Link to comment Share on other sites More sharing options...

adamzan Posted October 27, 2015 Share Posted October 27, 2015 I already used the spare when I got into a minor accident and bent the wheel. Kept the cash from the people that hit me, lol. Link to comment Share on other sites More sharing options...
01Pathmaker Posted October 27, 2015 Share Posted October 27, 2015 Correct on the wd21 backspace, sorry, I was still in R50 mindset. Link to comment Share on other sites More sharing options...
maddmark1981 Posted October 28, 2015 Author Share Posted October 28, 2015 I'm not in pathy territory, that's a fact... There just aren't any around and I have been looking for weeks... I'm going to keep searching until I find something tho... One question, how do I measure the backspace Sent from my MotoG3 using Tapatalk Link to comment Share on other sites More sharing options...
01Pathmaker Posted October 28, 2015 Share Posted October 28, 2015 (edited) Pretty simple, put a straight edge across the back of the wheel (where the bead of the tire sits not the lip, but if you do measure from the lip just be sure to subtract the height of the lip from your measurement), measure from the mounting flange (where the wheel meets the rotor/drum, the opposite side of where the lug nuts go) to the straight edge (subtract the depth of the lip if necessary) and you have your backspace. http://www.vintagewheelworks.com/tech-offset.php Edited October 28, 2015 by 01Pathmaker Link to comment Share on other sites More sharing options...
