285/60R20 on stock suspension + stock wheels 20x9

[Granite5thgen]

Yes. The 285/60s are about an inch taller than the 285/55s. Hope I don’t have any issues.

Yeah these were slightly taller and wider than the falkens and I was worried about a small rub. Even the tire guy called and said they would rub, so I was like great. But he was wrong thank God!

Zero rubbing at full lock in case anyone was wondering. Stock suspension, north edition adds 1" up front apparently so take that for what it's worth

North Edition is +1” front and rear I believe.

Got the Nittos installed this morning. I like them so far. The guy at Discount Tire showed me a slight rub in the front against a plastic piece of the wheel liner. But it's only in reverse and only during a full lock turn. I could trim the plastic a bit, but I'll probably just leave it alone.

A little more road noise than the street tires, but that's to be expected with AT tires. And the increased noise is really only noticeable at highway speeds of 65 and up. The ride is just as comfortable, if not maybe a little better than the street tires, and the Nittos track and handle very well. Plus, they look good. I'm pleased with them.

I cannot tell from the image, are these on the stock RAM wheels? Or did you trade them out as well?

They are on the stock Longhorn wheels. Liking the set up.

I'm looking to do same tire size on my 2019 Laramie, non off-road. However, have 3.21 gears (realized this at signing) otherwise truck has every other feature/package I wanted. Question if I should of purchased a rebel...

Which gear ratio you have with that setup? Looking to do same with mine 20x9 +18 or -14 offset, which ever will clear without a lift (Will do later). Much rather run 18" wheel, but not sure if will clear brake calipers. With 3.21 I'm worried that large of tire and gearing be too low, and will feel the performance loss?

Toxicfusion - I'm assuming your post was addressed to me? If so, I have 3.21 gears. I've not felt any performance loss. But I do have the Pulsar and I run it in Performance Mode. : ) I have noticed a slight decrease in gas mileage. Getting about 1/2 to 3/4 a mile less per gallon.

Was addressed to you, sorry for not clarifying! Just joined the forums .

Originally was thinking about doing 295/60/r20 but the 285/60/r20 is not much difference, slightly skinnier and less tall. Pulsar drop-in module is on my radar of things to purchase as well. Perhaps run tow/performance mode with 89 octane. Are you running 91oct all the time in perf. mode?

I guess I'm just getting caught up and emotional on being stuck with 3.21 gearing; as was an oversight on my behalf. Didnt realize with the 3.21 in the ram truck and bigger tire combo could have such negative effect on this engine/gearing combo.

We have 93 octane here in Central Texas so that's what I run. I never really thought about slightly bigger tires having a negative effect on performance. But that makes sense I guess. More unsprung weight with the bigger, heavier tires. But again, I don't really notice it performance wise.

Welcome to the forum.

I was not totally sure whether these tires would truly fit and function nicely on my stock suspension 19’ Big Horn Black Appearance Package. I read lots of posts on this forum but many seem to include tires of larger size coinciding with a level kit, full suspension lift, Ram Rebel, or air ride. Any of those can lend a great help to achieve proper ride heights for a larger A/T tire.

Today I pulled the trigger and had installed 285/60R20 Nitto Ridge Grapplers on my stock 20x9 wheels. These have completely changed the looks of my Black Appearance package Ram, in a very good way.

I do have a slight tire contact with my fender flare plastic during “FULL” lock while in reverse. However, this is trivial and the contact sounds like a baseball card placed in the spokes of a bike, turning at low speeds. LoL. Eventually I will get a level kit, but for now I’m not in a hurry.

Also, my speedo was reading at 71 on the highway while my GPS was clocking me at 73/74 (fluctuation). So a 2-3 mph difference. I plan to get the Rough Country calibration unit to sync my speedo and tire rotations.

Thanks all!!

Looks Great !!! My 285/60/20's go on Saturday with the black lug nuts , of course ! Found the Toyo RT's on Amazon for $248.78 each

Woops...wrong thread for this

Looks great, I'm getting wheels and tires done this week. Went with 285/55R20 toyo open country at2s and was looking for info like this, thanks for the post!

Any feedback on the at2? Do you have a pic?

Does your car come with ORG? and no level kit? Sorry to ask because i'm want to go the same route like you.

Hi, ghidora. My truck does not have the off road group and it is neither leveled or lifted. Hope this helps you.

Thanks for the info, so based on that and mine came with ORG so it shouldn't rub then.

 

[BeauxXL1200]

I think you'll be fine. I get a slight rub but only when full turns with the steering locked either to the right or left and it's mostly when in reverse. But with the ORG, you should be fine because I think your truck sits a little higher than mine. You'll like the Nitto Ridge Grapplers.

 

[Bionicbo]

Awesome, thanks for that info, makes me sure I can go with either 295/50/R20 or 305/55R20’s

Go with the 305/55, I went with the aggressive sport cooper zeon ltz since I do almost no off roading except for hauling boat to cottage.

 

[Granite5thgen]

At2s are awesome, 3rd set I've had. Decent hum but not loud. Great on road and off road manners imo.

I just mad the switch from Ford to Ram. I just received my ordered 2020 Larime with every option available. For this thread the most important feature are the off road group with air ride option. I think those tires are amazing, and interested in purchasing the same ones/size, but have a question. My last truck, (F150) had 305/55R20 Nitto Terra Grappler G2s. On a positive note, they were quite on the highway and when I towed my travel 5,500 travel trailer they performed fine. My issue is that they were a 10ply tire and the ride quality significantly changed in the winters and bad road conditions.

I live up in the Northeast, so the roads are beat up here. I'm interested in your feedback on how the ride feels over chatter bumps, frost heaves etc., and how those tires run in the snow?

Thank you
