I like it! Same color as mine too, only difference is I got the 6-1/2' box. I don't want to put the 1" leveler on mine...my brother did that with his old All Terrain & I thought it made it tougher to see the nose of the truck. I have a hard enough time seeing the front end the way it is with the shorter hood style (I had to put a 1-3/4" lift kit under the seats so I could see front end better). I don't really do much off-road driving (not counting gravel roads), the little I do isn't like extreme rock climbing or anything (construction sites and farm land). But we do get a pretty good amount of snow here though, so I don't know if that makes a difference or not with snow build up. How were you able to figure out which ones you could use without having them rub?

I barely notice the 1" level from the drivers seat. I think I notice the height of the tires far more. I did a 2.5" on my '17 SLT I had and certainly did notice the front end height difference on that.

 

Then again, I'm tall. My head hits the ceiling if I raise the seat too far so its different for everyone.

 

If you're in the snow def don't get these tires. We don't get any where I live but the reviews on them for snow are bad. But I think most M/T style tires are that way. Fwiw the original tire I wanted was Cooper AT3 XLT's - not nearly so aggressive as these but I do love this look.

 

For sizing I did a lot, and I mean a LOT of reading and looking at pics of other trucks. Realized height wasn't the issue so much as width with stock wheels. I would have gone with 35x11.50 if there was more styles available in them but most are 12.50's which will rub. Wheel spacers were an absolute "no" on my list of mods and I dont like really wide tires or a bunch of poke anyway so these are perfect for my taste.

 

I'm really particular on the look of tires so I would find one I liked and see if it was available in a 285/65R20 and then swapped to 295/60R20 when I kept running into backorder issues. I wasn't concerned with the price but more popular sizes cost less as well, but I'm not sure where those 2 fall on that list.

 

I highly recommend tiresize.com to get the exact size of the tire you have in mind, they can vary pretty wildly on actual size even though they're listed the same.

The whole truck being higher wouldn't bother me, just having the front end up higher is what would bug me; I'm only 5'8".

 

Yeah, height doesn't look like isn't much of an issue, but there's definitely not much room front to back, and don't really wanna rip my mud flaps off haha. I'm not a fan of wheel spacers or wide tires either. I don't like the look of them.

 

Thanks for the tip on tiresize.com and as I was google image searching I came across this haha

How is this setup holding up? Noticed any increased rubbing?  Also, are the 2: blocks still on the back of your truck?

Did you do any type of leveling kit on this?  You pretty happy with the ride and much road noise?

Following -- I just added 6112s on the highest setting and gained 1" up front.  I realize its a bit outside the original intent of the thread, but this is a great starting point for looking at tire sizes that will fit.

Is this a 18x9 +0? I'm looking at purchasing one of the following Method setups:

18x9 +0 with 285/70/18 (Good choice if I ever want to lift in the future)

or 18x9 +18 with 285/70/18 (Good choice for close to stock fitment)

 

I really dont want any rubbing or trimming since I travel quite a bit. How bad and where is the rub?

      OCI, not when but why?

      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.

      Poll: Does your truck have the rear window leak?

      By ShotgunZ71 · Posted

      Glad you had success with it. I did as well, but about 5-6 months later it returned. Tried again, same result. This was after the dealer made several attempts and never even got it to slow down.
