Biggest tires on stock RST? What if leveled?

What I’m reading is with a 2” level the widest you can go without rubbing would be a 285 but with a 60 aspect ratio.  This is for 20” wheels of course.

If you want to go to a 65 ratio you need to go slightly narrower with a 275 tire.

Jay Teez has  285/60’s

I have 275/65’s.  We both don’t have rubbing issues.

Bluerado has 285/65’s and has a slight rub in reverse at full lock.

We all have levels on our trucks.

Hope that helps.

Definently  helps me because once the tires I have now will need to be replaced I was considering going slightly wider to give myself a bit more rim protection but then I would have to go with a shorter tire.

I’ve kissed a few curbs and thankfully haven’t done any damage to my rims even with the 275’s!

The BFG’s do a good job deflecting the curb attacks!

How is the ride quality? Any issues?

The rub was almost nothing to be honest, I had to be full lock going in reverse and coming off a bad driveway angle. It was just touch but not even enough to cut whatever it touched

Good to know.  I’ll probably consider 285/65 BFG KO2’s after I burn through my current set to get the wider/even more aggressive look.

Thx

Just an FYI . I just put 275x65x20 on my 2019 Silverado with a leveling kit in the front. I had to remove the mud flaps but that was ok as I'm putting on fender flares.

I have the 2019 RST with a Rough Country leveling kit I'm running 275x65x20 on stock rims with the mud flaps removed with no problems.

      Well one of our most reliable vehicles was sold yesterday. The first and only I gave for free to a grandkid. If they got skin in the game they take care of it. My wife bought new. Five years later my daughter got it to use. We got it back and gave it to our grandson after graduation. He did zero maintenance just oil changes. When the AC quit he drove his mother’s car rather than get it fixed. Instead he just bought a beater and sold the Elantra.

      I usually do as well or better than the sticker for mileage. Usually better going west than east. North then South. Wind makes a difference. I’m not usually a conspiracy theorist. But it did dawn on me I’m going by the vehicle calculation. Now that would be interesting.

      What’s missing in all this is patience and investment in the future. Buy a 170K starter home. Ten years later sell it invest in a more expensive home. Eventually you’ll have a 600K home and pay starter home payments. Buy a starter car. Maintain it well. Save the payments after it’s payed for then buy an expensive car if you desire. Buy a tumbler make your own coffee, pack your lunch. Cook your own dinner. Most importantly take care of your car.

      People mislead themselves. Statistics are highly useful indicators.   Here's the tie-in to this thread. If an oil sample tests shows a wear indicator of 7 using cheaper ACDelco oil, and a wear indicator of 2 (lower = less wear) using a particular brand of Mobil oil, and wear has a linear relationship with engine lifespan, anyone could assume that Mobil is reducing wear by more than 50% (let's just say a 200% reduction for you red state people trying hard to do math) which leads to increasing engine life by 2x. Perhaps, in a vacuum, by itself, when dreamed by AI.   Yeah?! That's what the statistic is saying, isn't it?   No, it isn't. It didn't come out and say engine life is doubled. That's a very bad assumption, and a case of severe myopia by assuming something potentially untrue about the only data point in focus.   Average cost of a new car is 50k. You bet it is.   The median cost of a new car is more like 35k. Expensive cars are skewing the perception that "average" now means a $50k price of entry for a very average automobile. And that's not true. People who don't understand statistics twist the living heck out of them to mean all sorts of things they don't actually mean.   "Average" new car payment is $1000/month. Yep, it is. And in that number are all the $35k new car buyers who bring significant equity, and the $25k new car buyers who finance the car for a month just to get a rebate, and then pay it off. Know what isn't in that number? All the payments made by people who don't finance a car.   Picking one's own data point (don't have a car payment, never paid $50k for a new vehicle, my house cost $170k, I afforded a middle class lifestyle on $4.50/hr) is just a data point. Just like earning $25/hr in an area where the median home price is almost $1 Million is a data point. In fact, it's a lot of data points given that 80% of the US population lives in/around major cities. They're not idiots; the vast majority of them do it to make a living because that's where the big money is.   The highs have become higher, lows have become lower, and how your personal mileage varies is not truth for an entire country. At the same time you can't NOT acknowledge the data. While it doesn't paint YOUR personal picture, it certainly tints the reality that you also live in, as does your single data point.
