Needs more rubber in my opinion
Can't believe you drove 500 miles for those LOL must have gotten them for almost free

I literally think it is the lack of rubber that turns me off.

Definitely want to look into it. Wayyyy to much wheel gap.

I've started to read through the forums, but it looks like I can just swap in the SRT springs and it should lower the stance a bit, right? Or, it may be easier (and slightly cheaper) to buy the eibach springs. Just not 100% sure all that is involved, yet. But that's the plan!

Yes, it doesn't looks good. Too low profile tires on high suspension.
Most people are going the OEM SRT springs route, including myself if I find one. Some just put the rear to get better stance with the front. Exactly what I'm going to do. BUT in your case as you are running 22" with 40 low profile and there is toooo much wheel gap, you will need to lower more than SRT springs does to get a better stance IMO. OR if I were you will get different tires height% 50-55. And also as you have 9.5 rim, will go wider 285. Hell I'm on OEM 20"x8 and I will put 285/50/20 soon.

Re: Offset - Backspace - ideal fitment - Calculation chart

Rims and tires were brand new, so I didn't want to change the tires yet. Also, at the 40 height my speedo is still 100% accurate.

My first step will be looking into springs, tires will come much later.

Thanks for the info!

Re: Offset - Backspace - ideal fitment - Calculation chart

I think this is likely a novice question but I am going to asked it anyway.
If you move to 33" tires does this work with the TPMS system?
So I have stock Fortera and lookin go purchase either
ATTURO-TRAIL-BLADE-XT 33"x12..5 r20
NITTO Ridge Grappler 33x12.50R20LT F 119Q( when available)

Both on stock wheels. (I like the altitude wheels)

All modifications to fit completed and waitting on the Nitto specs before making final decision. . But would either tire require different psi for normal use?

neither will work with stock wheels, without a wheel spacer.....FYI.

Also, I have my Atturo 33x12.5s on my 20x8.5 wheels and feel thats the minimum width that should be considered for this tire. Another negative on the stock wheels, again...in my opinion

Re: Offset - Backspace - ideal fitment - Calculation chart

What does the " F 119Q" mean?

Yes agree with this issue, however using this as a pure example likely the
ATTURO-TRAIL-BLADE-XT 285/55/r20 and same for Nitto projected sizes.
These will both be with in spec for the wheel. Tires are about 1" thinner. Working with custom spacer to get close to optimum offset. My mocks ups and math are slightly different then the chart but I am vehicle specific and this vehicles suspension components exact locations.

Re: Offset - Backspace - ideal fitment - Calculation chart

Okay, I'm thinking about changing gears slightly with my 2014 WK2. I'm debating staying with my stock 20" wheels, the 2" OME lift, and 295/55/R20 tires. Those end up being 32.8" tall and 11.6" wide. If I fold the pinch seam and adjust the felt, I think they just may fit... Thoughts?
