Rc 2'' and tire sizes...experience?

stampede20 · March 11, 2012

So I'm sure that this topic has been talked about already, but I haven't been able to find it.

I have a 2009 Silverado 4WD with the the RC 2'' leveling kit, and a 1'' block kit in the rear. I also have the GM mud flaps on both front and back. Stock 18'x8' wheels with the stock 265 65 18 tires.

I am going to put on a set of Cooper AT3's or BF Goodrich All Terrain's and want to go up to either 275 65 18's, or 285 65 18's. Although the price for the 285's is significantly more, I would like to put them on.

My concern is if they will fit or not. The mudflaps do take up a little bit of space on the inside of the wheel well, and I dont want to rip them off with the bigger tires. Any idea how noticable the difference in size would be between the 275's and 285's with the naked eye?

If anyone knows for sure, or has experience with this same set-up, please let me know. Any pictures with the same set up?? It's too late to take $1,200-$1,300 worth of tires off and get money back if I see they rub! Thanks.

To the naked eye will be on an individual basis, but I dont think it would be much if at all.

285/65/18 would look the best IMO and fit fine, pics when you get tires!

The 285's will be just fine....and look great...but they're pricey! The 275/70/18 is another option as well

_{Yeah I typed that wrong. I meant to say 275 70's as the other option. Anyone else have that exact setup? Have you guys seen those tires fit in person, or is it just your opinion? Thanks for the comments. When I figure which ones I'm going with, I'll get them put on a take pics. Anyone have advice on Cooper AT3's or the BFGoodrich All-terrains? Opinions?}

275/70 or 285/65 will def fit. Coopers are awesome tires

Big Whiskey · March 13, 2012

I've seen both sizes actually fit in person, on a 1500 with a level kit. As far as BFG vs Cooper....I've had great luck with BFG's. I haven't tried the coopers yet, but I've heard great things about the AT3's. I really think either one is a great choice.

Ok thats what I was hoping to hear. Thanks for the help. Looking forward to putting them on. Hey "The Rod"...thats a good looking truck man!

stampede20 · March 14, 2012

I also forgot to ask. Where can I get my truck re-programmed for the bigger tires? I would like to keep my speedo and odometer accurate. Is that something I can do myself, or go to a dealer...or?

You will need a tuner to change those. You can go with any handheld that has that option, or my favorite..... Blackbear Performance. Its all controlled electronically.

Thank you very much. I'm very happy with how it turned out.

the AT3 is coming out with a C load range option... thats what I am waiting for. Hopefully wont ride too much harder Just food for thought.

txz71 · March 23, 2012

What sizes will be offered in the C load rating?

Big Whiskey · March 23, 2012

What sizes will be offered in the C load rating?

The 275/70/17 and 275/65/18 are offered in a Load E or Load C rating. Those are the only two I know of. There are also other sizes in P-rated...but they have fewer sidewall plies and shorter tread depth.
