Can I run 15" wheels on my Willy's?

    As Jeff said, "Plies" are only for a bias ply tire. Personally, I prefer, and currently run, C load rated tires. I never run a higher pressure than 40 psi (35 actually), nor any real loads, and I like a little softer sidewall (not sure if load rating affects this), so a D or E range tire is wasted for my needs.

    I have E rated tires on my rig. And here's why... E rated tired are really meant for trucks that are towing shit therefore needing a stronger sidewall. I don't tow anything with my jeep but I like a little stiffer sidewall just for strength against punctures on the trail. But even then shit still happens when you party naked

    Sounds like they'r finally making lower load ranges in 17.

    In 2013 I was looking for a load range C (6 ply) for my 4runner and there were only 3 options at the time and only a handful in D rated.

    Originally I wanted 15s for the 4runner but it has to be 17 or greater on that rig.

    Ended up with maxxis buckshot 2s and loved them. I put then on the jeep after the 4runner and they did great.

    That is until they got smoked by the the larger sidewall when I went down to 15s.

    IMO a 32x17 and a 35x15 feel very similar while driving and braking. The difference is very negligible. But the benefits of having 15s kickass off-road.

    There are ways to make anything work, and then there are best practices. The way to make a 15" wheel work is with extremely low backspacing (like you pictured). The down side to that is horrible scrub radius which results in extreme ball joint and unit bearing wear. Anytime we change BS for wheel fitment it affects the scrub radius, but there has to be a balance in there somewhere.

    If your Jeep is not a DD, no problem. But those of us that have to drive ours every day should keep these things in mind. Again, can it be done or should it be done.

    Pic below is a 17x9 wheel with 3.75" BS, you can see how close an upgraded tie rod end comes to it.

    That's some beefy tie-rod and knuckles in that pic of your TF axle.

    The 1 1/2 ton ends on the steersmarts stuff are some of the biggest I've seen. Great company if you're ever in the market!!

    @Blue Baby Sound. Awesome info on the scrub radius. I remember you posting on that in the past. My first thought on hardhats post. Holy crap. How long will his ball joints last. Anyway.

    I'm looking at upgrading tie rod and drag link. And I also remember your post while you were building your Wife's rig. While searching tie rods. I found the Steer Smarts Yeti. Again, remembering your post. But I was curious as to your experience with it. Any issues with it good bad and indifferent. Also. Do you recommend replacing any thing else along with THAT tie rod? Im also looking at TeraFlex's HD tie rod and drag link. I know as a DD. I really don't need them. But I do plan on hitting up some trails this year. Just want the best under my Jeep. Thanks.

    Our '14 has about 75k miles, all on 37s. A couple of years ago when I started researching tie rods for that Jeep I decided on steersmarts. So I had 2 years of pretty heavy beating on their tie/rod drag link combo when we started the wife's build. The wife's won't see a lot of action on the rocks, but mine does. It's taken everything I've given it.

    The only downside is their size, they're huge!! It takes a bit on the install to get all the bolts in the right place so there's no rubbing when stuffed.

    I haven't tried the TF, so I can't offer any experience on it.

    We've been busy on the wife's build lately, but here's a few shots of the '14 from the last year.

    Scrub radius shmadius. Doesn't matter. My jeep didn't flex nowhere near as good as it does now with the wider stance. Additionally it feels even better on streets and highways now.

    Watch "Jeep jk with 35s and 6 inch lift" on YouTube
