Biggest Tire on Factory 20's w/o Level or Lift

[Mulls1234]

Would anyone anticipate a difference in fitment between a stock 1500, and a stock 1500 w. air suspension?

I am going to drop the rear 2 inches. Looking at a set of 275-65R20 BFGOODRICH ALL-TERRAIN T-A KO2. Any idea with the lowering of my 4x4 the 2 inches if it will rub?

im sure that depends on what size tire your looking at. too big of a tire might cause problems with entry/exit mode i would imagine.

If I'm looking for a wider foot print on stock suspension with 20" wheels what can I fit?

It cost me $85 for install and another $70 for alignment with my HBS Leveling kit... I couldn't find any exact prices from previous purchasers so maybe that will help you

What he said. ^^^ you're into the entire thing for $200 including install and alignment and the look is SO much better.

I have a set of 33" mud terrain tires on stock suspension. No rubbing. Very quiet and look aggressive

What are the specs on your tires? You said 33's but are they 33x12.50? What is the magic number sir

275 65 20 will fit easy like the general at2 there a 34 inch tire tread is close to the bfg except 60,000 mile warrant where bfg has none n is atleast 80 bucks more per tire

Resurrecting this thread to ask if you have the air suspension with those 305/55r20s. I have stock air suspension with those same sport 20" wheels. Wondering if they will work in aero mode.

Any issues with 275/65R20 and 2" lift?

That is not a significant change from stock (slightly higher profile, no wider). Would not require a lift or level. Not sure what would be gained, other than throwing speedomete/odoneter off a rad.

You need to find another dealer. I picked up my new 2017 Ram 1500 Crew Cab Big Horn in January. Part of my ”deal” was swapping my nearly new Lt 275/60-20 MTv10 ply tires for the crappy OEM Goodyears. Deslervas a-ok with it. Have also had multiple discussions with technicians. Absolutely no warranty issues.

The one problem I have had, anywhere that does rotation wants to drop psi to stock, which is too soft for 10-ply.

I have a 2014 Ram 1500 with 20" factory rims. With my dealers ok, I went to same size Tire but in an LT 10 ply, instead of the P 4 ply. Which requires a leveling kit. Even though it was done by the dealer, I have developed a transfer case issue, which Ram is blaming the tire size. The transmission doesn't down shift in 4-high, and 4-high only. As I have learned the hard way, you CAN'T change from the P rated 4 ply original size tires. According to Ram, that size is the only size within their "programmable limits" for this truck. I live in the country and can't even drive down the pea-gravel driveway without getting a flat with a 4 ply tire.
Was also informed by Ram, with the new electronic controls, if you put a tire, different from the original or out of their "programmable limits", you WILL have drive train issues, and Ram will Not stand by the warranty. I have brought up the issue of payload and towing advertised is beyond the tires capabilities, to no avail...

Hey I'm new to this and to let some of you guys know that I have a 2012 Ram 1500 4x4 st and I can fit 35/12.50r20 on it with no rubbing and it is all stock no level or lift

 

[Ram_davis_1500]

I was reading through the messages on this and I am interested as well, I have a 2012 Ram will have a 6 inch lift on it and was told to run at the most 35 inch tires so that I don't have to change out the rear gears. Can I run 35x12.50r20's on the stock rims without spacers?

No you are going to still need spacers cause my bro has a 2009 and is running what you want to run and he has it on his and as in my last post I had to put it on mine as well to have no rubbing

Did you buy that truck used? That front end doesn’t look like stock height. Looks like it has a level on it.

Yeah your front end does not look stock height. I have 2012 with the bilsteins at 2.1 and my truck doesnt set thst high in the front. I have 295/60/20 toyo open country AT extremes and they rubbed and was very close to my control arms. I had to add a 1/4 spacer to keep from rubbing at full lock.

 

[Ram_davis_1500]

Yea it doesn't it feels a little higher and I had to add about the same so it doesn't rub

Yea I bought it used off a lot and that is what someone else told me but I didn't do anything to it and when I got it it didn't say that it had any mods to it and when I measured it the front and back was about an inch different so I'm not really sure and some people say cause it's a 4x4 it comes some what leveled

Your front is not stock, it's raised up prob with a spacer or leveling struts, nothing to do with been 4x4

So how can I tell if there is a leveling kit on it cause I really don't know what to look for cause I was looking to do one and I don't see the spacers the supposed to do it is there a other tipe of kits out there

Take a picture that shows the whole strut, look for a spacer underneath the strut tower top mount, if there is no spacer, the strut could be doing the leveling
