Ordered -
American Racing AR914's 18x8.5 Rims - 5.34 Back Spacing +15mm Offset
Cooper STT Pro's 305/70/18
My Rims Arrived, Ordered the Tires I dropped off the Rims to get them mounted.
Returned a few days later to have them installed on the Truck.
Was told that they were the WRONG Bolt pattern. I checked and they were correct. Wrong Bolt Pattern...
I ordered The AR 914 in a 6x135mm, I have the Conformation Proving that I ordered the 6x135mm and it says 6x135mm.
Summit insists that I ordered the 6x139.7mm and thats what they sent. While they did send them in 6x139.7mm my paperwork shows 6x135mm.
They insist that since I ordered them I have to pay to return/replace them.
Rather tired of talking with them..
Question - I'll be reordering the Rims. Most likely NOT from them.
The Proper Rims for a F-150 are ...
American Racing AR 914 in a 18" x 8.5" with a Backspacing of 5.93" and a Offset of 30mm.
These will be Mounted on the Cooper STT Pro 305/70/18.
I'm currently Running Stock 22" Harley Rims with Nitto G2's in 285/55/22. I installed 2" Spacers to get the wheels out a little bit.
Will the AR 914's with 5.93" backspacing and 30mm offset stick out a bit or will they stick out TOO much.
I'm looking to have what I have now with the Spacers. I'll even add smaller spacers if need be I just don't want to STICK OUT more.
Here is my current set up.
2" Wheel Spacers
Assuming your Harley rims are +44 offset.. with the 2" spacers you are at a -6 or so offset. The new rims in a +30, will be tucked in more. I would personally look for a 0 offset (which would get you to almost the exact poke as your current setup)
Edit: After doing the calculator your current rims (with spacers) will stick out only an inch more than the new setup.
I don't intend to use the Spacers.
So the American Racing Rims will stick out a total of 3 inches from Stock?
I don't want the Ricer Look.
This shows your stock setup (+44, Not using 2" spacers) compared to your 18" rim choice at +30)
So, the new setup will be 1" further out from your stock setup (no spacers).
Since you added 2" spacers and essentially turned your stock offset of +44 to -6, the new setup will be 1" closer to the truck then what you currently have (see image 1 from previous post). Therefore, if you want to get where you're at now, without using spacers, you should look for a rim closer to a 0 offset (image 2, previous post). Make sense?
I found out something wierd. At 40mph with my stock 275's I must not have been reading accurately. With my new 305's I'm dead nuts on. I'm gonna take a different route home and see if 60mph is still accurate.
Has anyone else experienced this? I haven't used my SCT tp reprogram my speedo yet.
I'd like to get the AR 914 Rims.
There 18" x 8.5" with 5.93 Backspacing and +30mm Offset
Running 1" out of Stock would be fine. I'd rather go this route and add 1" spacer to get were I'm at if I wanted to go out.
I just checked and the Harley Runs are 22" x 9" I've got some room in there to check while mounted. I'll check the Back Spacing & Offset.
There are not a lot of Rims that I do like.
Here are the Rims I'm looking at...

Same thing here. When I went from 275/55/20 to 275/60/20 I re-calibrated my speedo using a tuner, then compared it to a dash mounted GPS. Turns out the speedo didn't need calibrating, it must have been off a bit from day 1. Just changed tires and wheels to 305/55/20 and I'm going to call it good.
I took the expressway home at at 100km/h my garmin said 103. The parkway is 70kms/h and I do 80, garmin said I was doing 81. I think I'm gonna leave it.
yes.... and that's where you'd be. Those rims are huggggee negative offsets. There's no way a +30 will stick out even close to those. My rims I have now are +35 and I'm running 12.5" tires and they barely poked outside of the fenders, if at all. Which is why I did spacers originally and am now swapping them out for -12 rims.
