I have a 2014 GMC Sierra SLE and just put in a 2" Leveling kit.

 

My truck came with BFG Wranglers 265/65/18 and I wanted to upgrade to BFG All Terrain TA KO 275/70/18. The problem is they only come in 10ply.

 

I have heard with the new suspension you wouldn't really notice the difference but how rough would the 10 ply be?

Lol, you will notice it somewhat, the ride wouldn't be a deal breaker for me though, just don't put 80psi in them like they are rated for. You will probably notice a pretty good hit in MPG, not just because they are taller but that 10ply will be nearly 20lbs a tire heavier which is 50% heavier than the tire you have on it. Something to think about.

Oh, forgot to add that it's hard to beat a KO for the money.

It won't wallow around in corners like it does with the factory tires. I like the ride of mine.

 

IMO, the mileage hit most people experience is due to width, diameter or tread pattern. I switched to 10 ply from 4 ply and took literally no mileage hit. That said, you'll take a hit with the BFGs because they're an ancient, inefficient tread pattern. I don't understand how KO's are a good deal since they cost $50 a tire more than most, but everyone who has them seems to like em.

my BFG's got me out of some sticky situations in my old truck. it was a 2wd gmt-800 and I only got stuck with them once and that was mainly due to the fact that it was 2wd. I could keep up with a lot a 4wd trucks that had like a cooper all terrain or some similar to that. I will not put another all terrain on my truck. that is just my .02 cents. all though those nitto trail grapplers do look pretty sick...

I have the BFG allterrains t/a KO... They don't ride any harder than expected from a mud tire. No road noise, no issues, but again like mentioned above I'm running 40psi not the recommended. Those tires are good in all weather and my previous experience is that they can last up to 30-40k miles maybe even more depending on your driving style. They would very comparable to those Goodyear wrangler duratrac or any other M/T. My current tire size is the stock 265/65 on 18s.

In my experience, yes, you will feel the difference. I had BFG 285/55/R20's (10 ply) installed the day I picked it up. I had a vibration issue (the passenger seat vibrated like hell at hwy speed). After road force balance done by dealer and tire shop I still had vibration. Dealer said tires Tire shop said truck. After putting 5,000 miles on my truck vibrating I traded in the BFG's and put on Michelin LTS M/S (stock size), and what a DIFFERENCE. Maybe I had a defective tire in the bunch (couldn't prove it), but regardless, these tires are a lot stiffer than "P" rated tires. I ran 40 psi in the BFG's. They were also costing me 3 mpg.

This is where things are all over the map... I had confidence then I hear stories like this. The dealership says on the 2014's you won't notice much because of the suspension (as the put them on alot of new trucks) but I don't want to have the issues that you have had.

I can just tell you my experience. I think these trucks are the opposite of that (meaning very sensitive suspension). I also read on here a guy did level, and put on Mickey Thompsons, and then had vibration. The BFG's looked WAY better than my current Michelins, but it was shaking my truck apart. I have never owned BFG's before, but my neighbor has had several sets (and swears by them). He has also told me they are hard to balance.

You can notice the difference between the 10 ply and the slight increase in psi you will have to use. My last truck I put on a 10 ply tire and it was a big difference to me. This time I purposely avoided the 10 ply and got a 6 ply tire. It requires the same psi as stock and rides like stock. I personally would never get a 10 ply tire again unless I needed it for the increase load rating.

 

As a slight test to see if it will bother you. Take your stock tires and inflate them from 32 psi to 40 psi (assuming the tire can handle this pressure) and drive it around for a little bit. See if you can tell the difference. Then imagine that but even worse with the 10 ply.

His vibration can be caused by ANY faulty tire, it's not 10ply specific.

 

If you are worried about ride quality, you will definitely notice it. The guys that don't notice it are numb from the neck down, I'm the opposite, numb from the neck up. Lol 10 Ply's are very stiff, and heavy.

 

Word of advice, rarely trust the dealer. I just had them tell me that the speedometer will adjust itself if i was to change tire size and that wasn't a salesman, It was the service writer. (Technically I guess that's a salesman)
