285/70/17 Or 285/75/17

[big_country33]

i really like the BFG all terrain. i have been looking around and i can't find them in the 285/70/17, only 285/75/17. how much difference is there. is the 75 series taller or less tall. i am not a tire guy. has anybody put these tires on what size did you get, what load rating, what ply?

Also what are some other good looking tires with these sizes?

i have a gmt-900 silverado 4x4 with my RC leveling kit on its way

The rough country kit recommends 285/70/17 33" tall the other ones will be almost 34" tall, 33.83" to be exact. Those will probably rub in front even with the 2" leveling kit. As far as good looking tires, I like the factory look so Goodyear Wrangler AT/s look good, BFG rugged Trails, Nittos etc. I take it your mounting these on factory rims?

yes will be using my factory rims. the 75 series is taller then? i need a good tire that comes in the 70 series then because i can't find the BFG AT in the 70 series

Yes the 285/75/17 is almost over 3/4" taller than 285/70/17. I just checked and BFG AT T/A KOs do come in a 285/70/17s...

I would think you would have to trim a little plastic but I don't think it would be a ton of trimming... I could be wrong though

i have read a lot of post with ppl who have leveled their truck fit 285/70/17 without any trimming. i have read that actually they will fit without the leveling kit even. thats what i have read.

I know a 285/70/17 will fit without a leveling kit even I was saying I would think a 285/75/17 would fit.

Since you said you weren't a tire guy a 285 is the width of the tire in mm. The second number, say 70, is the height of your sidewall. 285/70 the sidewall is 70% of the 285 in sidewall height. So a 285/70/17 is a 33" tire while a 285/75/17 is almost a 34" tire like stated before. A 305/65/17 is a 33" as well. Hope this helped!

I just looked at tirerack.com, and they have 285 70 17 BFGs in two different load ratings. One being D range which is 220 bucks a tire, and the other is E range which is 228 a tire. People have different opinions about load ranges. Some like D because its lighter and people claim they stick better to the roads. Others say they like E better because they are heavier and have thicker side walls. Which ever you prefer.

I have 285/70/17 BFG AT on my 2005 1500 with a RC leveling kit. No rubbing at all on mine. I know your truck is different but you should be fine with a leveling kit. When looking at load ranges, the E load range is a 10ply tire. This load range is very popular in this size. A plus on the E range for this size when mounted on a 1500 is that you can run less air pressure allowing for a smoother ride. When I say less air pressure I mean versus mounting this tire under a 2500 which would require you run higher air pressure.You can run 35psi in a 285 E under a 1500 giving you a good ride and good tread wear as well. You should have no trouble finding this size tire in both D and E load range; its extremely popular.

Hi I had a very similar question. I was wondering if 285/70-17's would fit under a stock 1999 Silverado 1500 4wd. I do not want to do any trimming and do not want to "crank" the torsion bars. I would be willing to go up about an inch using the torsion bars but after that i would rather just go to a leveling kit. Pictures would be great as well Thanks in advance for any information.

I had an 02 and 285/70/17 LTX MS2's would not. I bought a set of Keys and blocks and went up 1 " in the rear and about 3" in the front.
They were 8 ply or D rated and are pretty stiff, I wouldn't wont 10 ply or E rated tires on a 1500.
I still have them on CenterLine's and plan on doing about the same lift or leveling on my 2011.

I used to work with a guy that ran 305's on the stock 06 gmc 17s and they barely rubbed with the way the t-bars were stock, 1 inch later and they never rubbed. All that being said, all trucks are alittle different and to each his own.
