Tire Size Fitment Master Thread

[BGDOGY]

Hey folks. So I've done a lot of searching and have come up with whole a lot of inconclusive. Wondering if I could get anyone with a similar spec's perspective.

I've got a '20 Lariat FX-4 with the BAP 18s. I'm going to level the front with ReadyLift 3" and lift the back with the 1" block. I want to put a set of KMC545 Trek 17x8 +18mm offset on Falken Wildpeak 285/70/R17s.

What's the rub situation here? Anyone with a similar spec?

(how she looks currently)

I installed the 2.5" leveling kit on the front of my my 2019 Lariat and I'm running 285/65-18 without any rubbing issues once I removed the plastic air dam. Crash bars are intact and my rims are a +30mm offset. The 285/70-18 are about an inch taller, so might rub some. Hope this helps.

So much information here I feel stupid asking, however many of the posts are customizing your ride for you enthusiasts. I have a 2021 XLT currently with 255/65R17 tires. I bought used so not sure if these were original or if the dealer put cheaper tires on. Anyway I would like to go to 265/70R17 without any lifts, level kits or other modifications. I will also be using OEM 17" wheels with +55mm offset. So will keeping things bone stock other than the increased tire size work without rubbing, etc.?

265/70r17 should work just fine. The door placard will have the OE tire size on it.

If you haven't already, this thread is a good reference: https://www.ranger5g.com/forum/threads/biggest-tires-no-lift.2458/

The consensus is that 265/70R-18 is the absolute max with factory wheel & no lift, but it also depends on how you're using the vehicle. If you go off-road and plan on flexing out the suspension you'll likely run into rubbing points. In that instance 265/65R-18 or 255/70R-18 would be considerations.

I've been combing this thread and either I have missed it or it's not here.

I have the leveling kit and want to move from the stock 18 inch rims to 17s. I like look of the extra rubber. I've been fiddling with the tire size calculator to find matching combos going from the 18 inch to the 17. Still I can not find the largest size I can fit, going to the 17s, with the leveling kit.

Ideas?

Apparently you can fit a 265/70/17 without a level. With a level you might be able to do 275/70/17? Have you checked this thread? https://www.ranger5g.com/forum/threads/biggest-tires-no-lift.2458/

Yeah, except I have a lift. If the level kit counts.

Hey guys, hope I’m not derailing the thread. I just bought a 2019 Ranger XLT FX4. The truck appears stock no suspension lift but is currently running 275/65/r18s. Is this possible or must it have spacers ?

If that's what you're currently running and there's no rubbing then I guess you're good to go, yes?

It’s rubs on full turn. Also pinky hardly fits. Wondering if I should downsize or level kit

Ah, then probably yes to either, whichever is gonna serve you best in the long run.

you can fit 285/70r17 on a stock truck. You get a small amount of rub, at full lock, in reverse. You can solve by removing the crash bars.

That being said: you can usually get a tire shop to test fit for clearance.

Can I put Ranger Raptor wheels and tires on my XLT without modifications or rubbing?

All everyone talks about is how they're gonna either level or lift their truck or use a spacer. I don't want to do any of that so I can't find an answer.

We would need to know the tire size and the offset of the wheel to help with that question. I believe the RR uses 285/70r17 tires, which means they'll fit, but you might have rubbing.

I had no issues with stock sport wheels (+55mm) with 285/70R17s with a 2.5" level and 1.5" Spacers. Ran them like that for 60,000 miles, never scrubbed once. I did unbolt and remove the crash bars.

Recently I have installed 315/70R17s with the same setup, trimmed the corners off of the fender flares and removed the honeycombs behind the fender wells. It does scrub before full lock. I ordered some steering rack spacers for now until I decide what I want to do next. There is about a half inch before the steering stop contacts when it scrubs the crash bar mounts.

Plug in the factory wheel-&-tire dims from your Ranger XLT door placard as Tire 1.

Plug in the factory wheel-&-tire dims from Ranger Raptor door placard as Tire 2.

There's no easy formula when it comes to suspension, wheel offset, well liner, and crash bar mods.

Visualizer tools will help you avoid major fitment mistakes. Just take accurate clearance measurements on your current setup -- before you commit to an alternate tire package.

Lots of wisdom here. Does require some patience though.

Best of luck.
