Tire sizes.

So I was wondering if it's a good idea or even possible to put one size up or maybe 2 sizes up from stock tires on my 16' off-road Taco without any lift kits and without rubbing the toes on the wheel wells when hitting bumps in the road. I want to keep the 16" stock rims which I personally think look great, but I want a bigger rubber so I sit higher up off the ground. I'm not familiar with mods at all. Much less terms and words, so sorry if the rubber thing i said makes a few of you laugh lol i'm not talking about condoms

 

Look at the tire calculator https://www.tacomaworld.com/tirecalc for comparative sizes.

Remember you only get the radius for 'lift', not the total diameter change.

Remember you are lowering your final gear ratio with a taller tire. Less RPM per MPH. But your speedo/odo will have error. And less seat of the pants 'grunt' at low RPM. (like street driving)

The tire calculator helps you understand all that.

Once you 'think' you know a size you'd be interested in trying, post back, and someone will be able to confirm if it will fit or not.

Your other choice is to wade through the dozens of threads here on the same topic. Not much fun.

 

That calculator is very helpful. Holy hell. I've always tried to understand the relationship of the x/x Rx when it comes to tire size. Thanks man. I'm sure there's a way I can pay a dealer to calibrate the speedometer after the swap. I got this truck because I wanted a brand new manual drive truck that wasn't a Nissan. The 16' manual drive tacos are only available in 4x4. Never had an off-road 4x4 vehicle before and can't wait to take it off-road. Already have. But nothing really needing 4x4 yet. Wanna lift it a bit before I try anything crazy

 

One size up, 265/75/16 you'll be fine on stock suspension, any more up and you'll rub.

No need to recalibrate the speedo as the difference will be minimal.

 

2.5 percent different, at least on mine with 265/75. Verified with highway mile marker speed test and 100 miles with GPS on and counting mile markers.

 

That equates to a 1.5 mph difference at 60mph for simpler explanation.

From what I was told after having mine checked for a speeding ticket, factory spec is +/- 5% so you might even find your speedo more accurate after the bump up in tire size.

 

I can't say for sure about the 3rd gens, but my 2007 always showed about 2-3 mph SLOW at 60 mph with stock tires. When I went to 265/75/16's the speedo is now correct. The odometer was reading about 2% off, now showing 98 miles when I actually drove 100. No biggie.

Any bigger and you start creating other problems to solve and more expense.

 

Just curious for tires and anyone running 33s, how is the power? Noticeable to the point you'd want to regear or not noticeable?

 

Not gonna happen. If you get it far off enough to mess with, this is the answer you need.

Bigger tires, w/o suspension changes, aren't going to get enough lift to matter. Different tires, in terms of tread pattern and such, will give you more off road grip, if you pick the right ones for your use.

Since you are an off road novice, I recommend driving it like it is. Learn how to recover it if you get stuck. Learn how to drive it so you don't get stuck. They are very capable as is, even with OE tires. When you learn to drive off road, you'll be able to navigate places in 2wd that novices need 4wd for. The loose nut behind the wheel matters.

Tip: Figure out your use of the truck 80% of the time, and make mods that make that time more enjoyable. If you build to the 20%, the other 80 won't be nearly as much fun.
