New to the forum, need tech advice on backspacing 🍻
#11
No need to run 10" wide wheels with a 35x12.5 tire. Just get a 17x 8" wheel with 4.5" backspacing. Tires will clear the control arms and firewall at full lock. It will also give you a decent scrub radius and keep your unit bearings (hub bearings) alive longer.
I run 4.75" back spacing on my 17X8" wheels and clear 37" tires. Though my control arms are not stock so rubbing when turning is a non issue.

Srry for the slow responses guys, my work schedule isn't ideal as u can tell from my post times, I get drained during the week haha
Is the geometry the same for the v8/V10 and diesel 2500s? Asking cause I've looked and looked and there are very few V10 guys and even fewer V8 3/4 ton guys but there are a ton of cummins threads of lifts etc if they're all the same then that'l be easy enough to do.
Jlake, do you have any pics you can post? I was only saying a 10 inch wheel cause that's the middle ground spec for the MXT according to their sizing chart, do I need to mess with offset to have them sitting flush with my pocket flares or will that combo do the job?
Also as I've deduced before I'm not lifted or even leveled although a leveling kit might be in the future and I do have a 5 inch lift kit I've been eyeing in case I do want to go that route. That being said and all things the same with a 17x8 wheel with 4.5 backspace and whichever offset (my half tons I got wheels with a -38 mm offset I believe, same BS at 4.5) would 36s be within realm of possibility? Truck came with 4.10s from the factory according to the tag under the hood so gearing shouldn't be too bad for it. If I can go the 36s I'd rather do that, what are your guys' houghts?

I'm running 35-12.5/17 Generals on Grid GD01 17x9 rims with a +15mm offset. The truck is stock height 2500 V10 with newer mopar diesel springs in the front. At full lock, I rub just a little on the back of the inner fender on which ever side has the bump out of the inner fender( I can't recall and am to lazy to go out and look).

Excellent info HeyYou, I wasn't sure if they were the same specs however I knew that the springs were heavier esp for the diesel since the engine and trans weigh alot lol
Jimy, those extendaflares you got on ur V10?
Anymore pics from a front view or down the sides to see how well the tires fill out to them?
I'll be getting measurements today (day off) on how far in my tires are compared to the edge of the flares, as well as the exact tire size that's on there now, and I'm also going to turn full lock and see just exactly where I'm rubbing and by how much -sidewall tread is what hits the arms something fierce lol-
Got a busy weekend so I'll try to have them all up today, I appreciate all of the help from you guys this far!

I haven't crawled under there yet but I'm almost 100% sure it's on the arms, I was under there last weekend (shift linkage has no bushings in it so go figure) and the fenders looked like nothing hit them so it's just the control arms as far as I know/can tell.
If the stock bs is 4.5 should I try for an even 4 or 4.25 or should I keep the bs stock and use offset to move them away? Was in the Cummins section and saw a guy running with 35s on a -44 offset I think it was, pushed his tires past the fender but he had no pocket flares, just by visual it looks as though if he did they would fit even with the flares and not be so stuffed/recessed in the wheel well like mine are, they look so goofy when u can see the depth difference, good meaty look but way too sucked up in there for sure haha
