offset? please help!!

Venomous281 · 11-17-2012, 07:38 AM

Im getting ready to order my wheels and tires but im not sure what offset i need for my truck. Its a 2010 crew cab SE 4x4 titan. I have a 3" front leveling kit and a 1" rear block. I want to order 18x9 Fuel Hostage wheels and 295/70R18 Nitto Trail Grappler M/T tires. These are the offsets available -12mm, +1mm, +14mm, or +20mm offset. Any help or pictures would greatly help. As soon as i find out what offset im ordering them.

Depends on what look you are going for. If you want the wheels to stick out a little go for the -12. If you want them to tuck under the fenders +20.

+20 or +14mm if you want to do minimal trimming and +1mm offset if you want a more aggressive look and don't mind doing a lot of trimming. You may run into some pretty bad rubbing with the -12mm but they will give you the most aggressive look. I honestly wouldn't recommend running a 35" tire with that aggressive of an offset with out a 6" lift. It basically comes down to how much trimming you want to do.

Sorry to hijack the thread by my question is similar to the original one posted.

Regarding offset, I have a choice between -12 or 12.

305/50R20 is the size I am looking to put on a 2008 4x4 LE with a leveling kit, air bags Bushwacker fender flares.

The current set up is 305/40R22.

12 mm off set will push the wheels out wider? If so what are the consequences, if any, for tire clearance on the given the previously mentioned specs. I would like to go to wider stance if possible.

Thanks in advance.

The less offset means the wider the stance. You should be fine with the -12mm offset because the tire you mentioned is actually a little bit smaller than stock but an 1.5" wider. I am assuming your going with a 9" wide wheel. The -12mm offset will definitely give you that wide aggressive stance. If you ever plan to go any larger than stock you should go with the 12mm. Also what tire are you going with because all manufactures are different the dimensions i used are the nitto terra graps?

Yjotun · 11-21-2012, 08:33 AM

You are correct, I am going wit a 9'' wide rim.

Haven't actually decided on tires yet, I'm try to figure out wheels first. I found a tire size conversion chart that said 305/50R20 is = 32'' x 12.5'', is a 33'' stock?

How much do the dimensions vary from manufacturer to manufacturer? I thought the dimensions would all be standard.

What I am looking for is 32" or 33" x 12.5 wide R20 or R18 something that works well in snow and looks rugged. I have checked out the BFG TA KO and the Toyo open country AT but I'm not really sure which I prefer. Also open to suggestions on tire selection.

Thanks again for the help.

Check out rimsntires.com and click on the size comparer on the left. A good visualizer for how offset, rim size, and tire size work together.

WOW! that is useful. Thanks bro.

edit - I realized that may have sounded sarcastic. But I assure you it was genuine. Thanks again.

The difference between manufactures is usually somewhat close, but its best to look at their size specifications to be positive.

Hey

I'm leaning towards a Goodyear Territory in a 275/70/R18 on 18x9 rims with a -12 offset. Part of the reason is I can get those Duratracs for a smokin' deal new.

Just looking for some opinions on how you guys feel that narrow of a tire will look?

This is the truck as it sits currently. I'm not a fan of the tires and wheels and they have to be upgraded anyway for the winter.

currently its running 305/40/R22

Thanks again for the input guys.

You need a narrower rim or a wider tire. The DuraTracs, at least, are spec'd for an 8.5" maximum width rim. Found the Territory spec's for a LT275/70R18 at Canadian Tire ... same maximum width.

You could go with the shorter LT275/65R18 at 32" diameter but if it were me, I'd get the DuraTrac in the LT295/65R18 at 33.1" diameter.

Yjotun · 11-23-2012, 01:36 PM

I am glad I asked. Thanks for clearing that up for me. The 295/65/R18 Duratracs look like the answer.

Thinking that These wheels are the ones. I think a -12 offset should fit?

You might, (very likely will), need the pinch weld mod and front mud guard removal with a 9" width and -12 mm offset and a 33 on a leveled Titan. The -12 mm on a 9" width rim stick out 2" more than stock, so make a bigger arc when you turn.

Then a possible issue is the spokes might rub on the calipers. I had this happen and just got wheel spacers to give 7 mm of extra clearance. I you had to do that, even more likely you would need the PWM. It's not a big thing though, (see the last link in my sig). But depends on what your definitions of "fit" is. If I was going for a 9" with just a level, I'd probably pick a 0 mm, or better yet, a +12 mm if I wanted to avoid the PWM.
