Need help with Wheel/Tire Combo

tlowery33 · March 2, 2018

I have a 2014 Sierra 1500. Everything is currently stock. i might add a leveling kit or small lift sometime in the future. But i am currently looking to get some new wheels since it is almost time for new tires. I am not too good with the calculations so i was hoping you all could help. I am looking into the Fuel assault wheels (18"x9") paired with Goodyear Wrangler Duratrec tires (265x65R18). These are offered in -12mm, 01mm, 20mm offset. which offset would be best? I wouldn't mind the tires sticking out slightly, but nothing obnoxious. Also will these tires fit without rubbing?

I was also looking at the same setup but with the fuel assault wheels (20"x9") paired with the Goodyear Duratrec tires (275x55R20). Would these fit without rubbing? Also, what offset? They are offered in 1mm and 20 mm).

Like I said i am new to this but would like to add a more aggressive look to my truck when i get new tires. I just want to make sure they fit without rubbing or any other problems.

thanks in advance!

Might be a answer in this thread somewhere.

265/65/18 is a stock size and 18x9 is only half inch wider than stock wheels. That combo will fit fine. I think stock offset is 24mm, so stay close to that.

Actually it's +31 mm.

Never understood why GM insists on running 275/55-20 but only a smaller 265/65-18 when a 275/65-18 is the same size. Get 275/65-18's.

These tires are stock size so if you go with this setup, the +20 offset will be just slightly wider than stock (because stock wheels are usually +24 offset, for 18" wheel). This will fit no problem.

Thought: Why don't you look into a simple level? (assuming you don't want a full lift) This will definitely ensure that you will fit a bigger and/or wider tire

2014-2018 half tons have a -24 backspacing. I think the -31 backspacing was 2013 and older.
At least this is the info I obtained wheel I was looking to buy wheels.

I think this might be correct...

However "+24 and +31".. definitely not negative offsets on stock wheels.

Oops ... Yes you're correct. I sure didn't mean to say negative.

Here's my 2017 with 18x9 fuel octanes, +1 offset, and 275/70r18 with a 2" level. Sits just right I think, and no rubbing at all.

That's exactly what I am looking for! Nice truck, love the way it sits. What brand tires did you go with? Also what 2" level did you go with and about how much does the cost? I would like to do that but wasn't sure if it would void any warranties or anything. Also, did you instal it yourself? Im curious to see how difficult it is to install.

That is definitely something I am considering. Just wasn't sure how much it cost and if it is easy to install or not. Also wasn't sure if it would void the warranty.

Cooper STT pro. It's a zone 2" level but they are all pretty much the same. I think they cost about 60$ but I went with zone because my dealer had them in stock and they installed it as part of my purchase deal when I took delivery. The 2" under strut levels like the zone or rough country are an easy install and I've done a few on my old trucks and friends trucks, and can be done in about 1-2 hours. As for warranty depends on your dealer but my dealer installed mine and said it wouldn't affect my warranty at all

Man 18"s look good on these trucks.

22" OEM wheels are just plain dumb, and incredibly silly.... (And yes, I currently am stuck with OEM 22" wheels..)
