2018 Tacoma 4-cylinder engine. It is possible with 33" tires?

I have a 2018 Tacoma, 4-cylinder engine, 4x4, access cab.

Could I put 33" tires on it without having to change the crown and pinion of the differentials? Would engine performance be affected by this new tire size?

If I have to change the ratio of the differentials (crown and pinion), what is the ratio that comes from the factory on my Tacoma and what would be the new ratio that I should put on it for 33" tires?

Thanks!!!

 

You could put on 33’s and not change anything else, but the performance will be bad.

I always question everyone’s “build” where they think that they immediately need to put on 33’s…

 

I'd not recommend it. Depending on width and wheel diameter, most 33s are going to be a load E tire, e.g. heavy as fuck.

Gearing helps, but you're still fighting physics for looks.

There are a lot of load C tires in the 32" range, and a lot of SL tires in the 31.5" range. I would be shopping those. I personally hate going over 45 pounds per corner, and I refuse to go 50 pounds per, and that's with a six banger pushing it. I would be even more weight conscious in a 4 cyl.

 

Thanks @JasonLee !!!

 

Excellent @Rock Lobster. Thanks!!!

 

more on Rock Lobster’s point -
255/75R17 is a good 32” tire that you can get under 45lbs…

I put heavy E range 31.5” tires on my 2003 with V6 and it killed performance. On my current 2015 with supercharged V6, I spent the extra money to get the lightest (within reasonable price) wheels at 21lbs and have ~45lb load range C 32” tires.

 

I would just get really nice tires in the stock size which is probably what I’m going to do unless I can’t find any then I’ll just go up to 265s.

 

I will take into account all your comments. Thanks!!!

 

FWIW, I run 33s (Falken Wildpeaks A/T3W 285/75R16) on the 2.7L and stock gearing.
With armor, winch, bumper, camper shell, and then tools, recovery gear, supplies, etc., as required. It's fine.
Each addition came at the expense of a little acceleration- I got used to it.
And some weight was beneficial, as it keeps the truck more planted.

Am I slower than granny in her VW Beetle on her way to Sunday mass, unless I put my foot through it?
Yes.
And does doing so get me naught but the mildest acceleration for my tank-draining effort?
Also, yes.

So it's fine.

But.......I roll a 5-speed manual, so YMMV.

And, whatever your gearing, I expect you would have trouble clearing 33" tires on stock suspension (they will rub the truck body) when you have the front wheels turned. This would be most noticeable when your suspension is compressed.
I had the cab mounts trimmed, and a suspension lift installed (along with some other stuff), to get 33s to fit properly.

It's a 4cyl. Wasn't meant for that.
They have a larger engine option.

If larger tires were more efficient they'd come with them.

 

Thanks for the information @ssd_dan. It is very helpful!!!

 

There is another way. The new trend is to go skinny.

There are a few tire sizes that can get a true 32 without a huge weight penalty or fender rub. I kind of hinted at it earlier, and JasonLee expanded on that thought. There are also a few sizes not mentioned in that linked thread mainly because they have a similar diameter to a more popular width. But it's definitely worth hopping onto a tire site and playing with what's available in the 255, 245, or 235 ranges. You'll keep the weight down and have a cooler looking tire. Cake, meet fork.

 

I wouldn’t do it.
The 2.7 in my 2nd Gen PreRunner AC was a slug.
Your 3rd Gen weighs more. It won’t hurt the 2.7. But you’ll definitely notice a performance hit.

I still think Toyota should have offered a 4.56 gear for the 2.7. Or at least made 4.30 the standard for 4x4 trucks.

The 2.7 already drinks gas. The gears won’t make it that much worse.

 

Your comment is very interesting @Rock Lobster. The 255/85/R16 seems quite accurate to me. Thanks!!!
