35x12.50r20

[2016ram1500exp]

Trying to decide what's my best option I have a set of blue fuel contra wheels that I know I want to get a set of 35x12.50r20 on there just wondering what others have done spacer wise I have a leveling kit and an off road bumper so height shouldn't be an issue.

What offset is on the wheels?......that tire should fit with your leveling kit ...... unless your running factory offset

Need to know the width of the wheel as well.

35x12.5 will fit the fender wells just fine, but the width and offset may cause the tire to interfere with the control arms.

 

[2016ram1500exp]

My new wheels are 20×9 unfortunately the offset is a +20 and now I just picked up a brand new rough country 4"lift and there 20×9 offset requirements are a minimum of +1 just trying to get it all ready so I can do it all at the same time but I don't see how I'm not gonna have to do one before the other so I don't have to get multiple spacers made if the lift ends up needing more clearance now.

 

[heckcat9]

When they told you +1 minimum offset, I assume they mean +1 or less? As offset decreases, back spacing decreases and you get more clearance between the wheel and suspension (the wheel moves outboard).

The +20mm to +1mm offset delta is -19mm or 0.748 inches. A 3/4 inch spacer will get your wheels from an ET+20 to ET+1 offset. The spacer will decrease your backspacing from 5.25 inches to 4.5 inches as well.

Edit: Based on RC's list of known working wheel and tire sizes, you can go down to a -12 offset without trimming. Going from a +20 to -12 offset would require a 1.25 inch spacer.

Ok good so if I'm looking at this right I see it showing an offset of +0 or is it like you said a -12? I'm hoping since I have the offroad bumper the trimming aspect shouldn't really be an issue that being said do you know what size our stud length is as I have to get a hubcentric spacer because of the hub size difference and the machine shop in maryland I'm working with is making ones that I will be using my hub studs instead of mounting new studs into the spacer to make less points of contacts so now I need to figure out if a .75 spacer and my wheel will actually make it on there with enough turns to get my lugs to torque specs

 

[heckcat9]

35x12.5R20 on 20x9 wheels with +1, +0, and -12 offsets are all listed there.

Sounds like you want to use a washer style spacer. Factory studs are around 1.5" I believe. I would not recommend using factory studs with a washer spacer, specially a >1" spacer. I ran those quite a bit on my track cars and always installed longer studs to account for the threads lost to the spacer.

 

[2016ram1500exp]

Ok do you know anywhere that has any extended studs? As I can't find anything for our trucks.

This is probably your best option.....https://supremesuspensions.com/products/2012-2016-ram-truck-1500-1-5-wheel-spacers-hub-centric

 

[2016ram1500exp]

Ok yea thats almost what I'm feeling like I'm gonna have to regardless I just worry about spacers but as long as it's a hub-centric spacer and put on right is it safe?

 

[co-pilot]

Lot of guys on this forum run them.......but I honestly have never used them...

 

[heckcat9]

The spacers should be fine. As long as they are torqued properly and aren't some kind of Chinazon Prime or other sketchy brand, you won't have any issues beyond additional wear on your wheel bearings, similar to having super stance'd negative offset wheels...

I ended up with 2'' Supreme Suspensions spacers IIRC?

 

[2016ram1500exp]

Ok thank you guys I went with a set of bora 1.5" spacers sucks it says about 4 weeks to get but will be worth the wait for sure. I'll post an update when everything gets done

 

[2016ram1500exp]

Now what about a hub ring on a spacer?

 

[2016ram1500exp]

As my hub is 77.8 and my wheel hub is 106

 

[co-pilot]

What does the ring on the spacer measure?

 

[heckcat9]

The outer diameter of the hub and the inner diameter of the wheel's center bore. In this case it adapts a 77.8mm OD hub to a 106mm ID wheel. I've never run hubcentric adapters so I can't give OP a definitive answer here.

Yeah I was asking about the lip on the Bora spacers....sorry for the confusion

 

[2016ram1500exp]

Well everything is in besides my KSP upper control arms and lower ball joints. Spacers and wheel hug adapter are a perfect fit now to just wait on my truck to get back from the painters for a hood touch up. I'll post pictures with everything once finished.

Not the best picture but man was I excited I recommend if your in southern Maryland area to get your lift done by Halsey's Automotive in Leonardtown MD provided my own lift, tires, wheels, alignment and to get the lift install was $875.00 which was very reasonable I believe. I'll post more pictures tomorrow.
