Stock Suspension - 20x10 -18 (Looking for Feedback)

[anthonysnell]

I would like to know from Forum members, feedback on the largest tire size that can fit on a 10x20 -18 rim with stock suspension and resulting in no tire rub. Ideally, I would like a 305/55 (33" x 12.5"). I've seen a couple of examples on Custom Wheel Offsets (one stock suspension, one air ) that state no rubbing, but second guessing it. Any recommendations that would allow me to stay around 33" with as much sidewall as possible.

Thank you

That might not fit without modifications to the wheel wells. I test fit 18x9 -12 with 33x12.50 ridge grapplers and they just barely cleared. Keep in mind 33x12.50 are actually 32.75" and 305/55 measure out at 33.25", 295 55 20 will likely fit without mods on stock suspension

You are going to have alot of tire outside of the wheel wells. Where I live 1. You'll get pulled over by the 5.0, 2. The road debris will destroy your truck. If your going to do that I'd get some fender flares on pronto. Your gas mileage will also get hammered, assume you already know that though

I went +18mm with 35in x 11.5in Nitto Ridge Grapplers.. Fits like a glove

What was the tire size? I know you said 35x 11.5 but i'm looking for the size. Also, did you say that this size with a +18 offset fits perfect? No rub? And how far do they stick out past the side of the truck or fender well?

 

[Icecold77]

That is a size.. I recommend you utilize a number of websites that do the calculations for you.. put tire comparison into google.. Yes it fits perfect... Ive done this many times.. 1st. Understand the factory wheel offset, then determine what you want to do. + wheel offset pushes the wheel in... as you move to 0 and negative that's the wheel going out... I'll help, tell me what you want to achieve?

Put your stock #s in and see what it shows you..

I'm running 305 50r 20's on factory 20x9 wheels. Only rub I have is full lock in exit entry mode on air

says 35x11.50r20 on the tire in the pic

i gotcha. i never zoomed in when i first looked, i just read the thread responded before thinking. anyway, i think those Ridge Grapplers are the bomb. and thats exactly what i want to get. 35x11.5R20 on RG's.
how far past the fender does this set up stick out? or is it flush?
what i am wanting is either flush or sticking a little past, say no more than 3/4"-1"

Just had my wheels & tires put on today. No rub or issues at all (not even close). Love the look while still a good freeway ride (4ply XL). 305/50r20

(Thanks 19Streak for some reassurance prior!)

Not gonna do any level or lift. Had issues doing that in the past and happy with things as-is. Finishing replacing the chrome window trim with Mopar black later today. Otherwise -- done.

Cheers.

Sasquatch, do you know what offset your wheels are?

 

[TheSasquatch]

Yep! Wheels are 20x9 +1 -- They also have a +20 I believe in this wheel. But, of course I wanted it to go out a little at least! I think the offset is really perfect. If I wasn't a freeway driver most of the time, I'd probably have done RidgeGrapplers for a little more off-road look. Also, after I'd ordered the Hankooks, I second-guessed myself and think maybe I would've done General Grabber ATX's as they have nearly 100% rating on TireRack and look a bit more aggressive while still having the A/T tread.

 

[DeDax]

I think the +1 really is a perfect choice well done. I like the Hankooks, had a set on my F150, not super familiar with the ATX but with 100% rating seems like i need to be

 

[TheSasquatch]

Yep I had 295/60r20 Hankooks on my 2018 F-150 Platinum and loved the traction. But they were 10ply and ruined the cush of my ride. I'll never make that mistake again! (Referring to the entire truck!
Dumped that thing after spending the entire 10 months blacking it out. lol #HATE
