Question / Advice needed about wheel/tire sizes

So I am wanting to get some new wheels. The ones I want are only available in 17x9; and of course the stock wheels are 16”. So I will need to buy some new tires.

Questions:
1) My truck is factory, no lift. What size tires can I fit, that won’t rub and shouldn’t affect speedometer accuracy?

2) Eventually, I would like to get a leveling kit. so whatever tires I get now, I’m hoping that they would still fit and look good after leveling. Basically, not look too small or out of proportion to the truck height, stance?

3) The wheels are 17x9 and have an offset of -12. What can I expect as far as width? How far will they stick out? Will that size look good?

4) Any other suggestions or thoughts I should also consider or be aware of?

Thanks in advance for the help!

 

Hope this helps a bit.

 

245/70-17 = 30.5" diameter which is the same as 245/75-16

 

The new wheels are going to poke out 2.5" more per side, a fairly drastic increase. Even on stock tire size that puts you at a pretty decent chance of rubbing so anything larger is damn near guaranteed to rub. Something I would think hard about and whether or not you're prepared to do a fair bit of cutting to avoid rubbing.

 

Love my 265 75 16 Duratracs, but am hoping in the future that a 255 85 16 or 255 80 17 tire will be under my Taco.

 

I’ll also mention, the farther out they are offset, the more unevenly your wheel bearings will be loaded which may accelerate wear. Also, with a 9 inch width, you will need a fairly wide tire to fit properly. Trying to run a skinny on a moderately wide wheel will lead to the tire being pulled out which can lead to the tires wearing unevenly, usually wearing less in the middle due to the pull. Running a too-wide wheel can also lead to it being more prone to losing a bead under low pressure and you will have less traction and braking capability.
I’m more of a function over form person. I would either buy a tire that fits the rim properly or buy another wheel. I would shoot for the middle of the wheel size range. 245/70/17 has an upper width of 8 inches, so you would end up with a pulled tire, if an installer would even mount it. Aside from that, it would look ridiculous. Realistically, a 285 would be a better fit for the rim but wouldn’t meet your other parameters.
You might consider a different rim which comes in a narrower width and will accommodate a tire you want, or lift/CMC/trim etc., to use a proper tire for that rim width.
There are no magical solutions here. Rim/tire/lift choices are all give and take choices. Generally, the larger the rim, the larger the tire, and inevitably, the larger the lift and more parts changes/trimming. Of course, doing it right adds up quickly. What is your overall goal?
It’s your truck, and yours to do as you like. I assume you are trying to make an informed decision here. I’ve done lots of wheels and tires/lifts, from minor to pretty big. I’m aware of the trade offs, so I’m very function focused because I don’t like wasting money over bad choices or dealing with unwanted side effects. This stuff is always a plan with me. I never start without the end in mind or hoping that somehow it will all just magically work out.

 

Where did you source that from?

 

Here. It was a response by tonered to me posting a very similar question when I first joined this page. Asked about possible tire sizes with different suspensions because I was moving from a second generation to a third generation Tacoma. I see it everywhere…very accurate.

 

On my 2021 sport 4x4 I run 4runner trd pro replicas that are 17x9 with a zero offset. My tires are 265 70 17 BFG Ko2's. I was stock height and had no issues. Now I'm running a 2 inch leveling kit and it looks great IMHO

 

I greatly appreciate all of the replies and knowledge here. A lot of good info, with many factors I need to consider, that I wasn’t even thinking of. Unfortunately, it’s been a crazy work day for me, so I’ll respond as soon as I can. Have a few questions.
