Speedo recalibrator after larger tires?

Anyone Know if there is a re calibrator on the market for larger tires? Going 85 but spedo says 72 lol.

 

already did thanks for pointing that out though.

 

Just make a mental note of how much you are off at normal posted speed limits and drive accordingly. Also, enjoy your now lower-than-actual odometer reading and improved resale/trade value!

 

LOL, I don't buy a truck thinking about when /if going to sell it. Thats like dating a girl and not doing it with her cause your saving her for the next guy.

 

Uhh, I didn't say that's why your bought your truck, I said you might as well enjoy the added perk of lower mileage you now have. So, bone away! Oh wait, you're in Alabama....this isn't your sister is it??? Because I can't be complicit in that.

 

LOL good one, havent heard that before. Youd be a complete moran buying a Tundra and worrying about gas mileage.

 

Damn, dude...you must be from a looong line of "Alabamians"! Who said anything about gas mileage? Looks like you're the morOn. Reading comprehension is lost on you.

 

Man typos happen. I wasnt calling you a moron if you look above. Glad to see there are members on here that come into other ppls posts that they're trying to get help only to make fun of where they live and call them names. Appreciate it.

 

I *WAS* trying to offer help...and, well...it spiraled downwards from there. It's all good man - all said in jest. Carry on.

 

Well…this thread took a hard left.

 

The “Tundras.com way”

 

So I’ve called a few companies about a recalibration and no one has yet to develop one, that I could find. Been trying to fix the issue as well. Mines off by 5+.

 

I run 37" tires and my speedo is off 10%. So, if my speedo is 60mph, my actual speed is 66mph. When speedo is 70mph, actual speed is 77mph.

When your speedo us 72mph your actual speed is 85mph? Are you running tires larger than 37 inches?

 

Nope 35's, Both my phone GPS and my speed on waze says im going that fast too. Its like 83-85 somewhere in there

 

They're using the same accelerometer in your phone so they would/should read the same.

With 35’s, as @romanlegion said, it should only be about 10% difference.

 

Sorry, but those numbers do not compute. If you're running 35s and your speedo says 72mph, I'll venture to guess Waze will show you're doing maybe 77mph.

 

Ill take a vid and post later

 

Yeah, the recalibration is not out yet, they are working on it though. Should be out this year.

 

Hypertech?

 

That is correct, yes

the 23 4 Runner is out and Tacoma I believe but the Tundra isn't

probably because Toyota sells more of them.

 

I'm on 37's and I'm definitely right about 10% off.

GPS shows 66, speedo shows 60, GPS shows 77, speedo shows 70, ect.

I've just adapted to knowing my offsets, but a correction would be nice.

 

For 35s he might actually be off closer to 6% or 7%.

 

Hypertech has been working on it since early Oct 2022. That's when I called them to see if they had one available. I guess no one has a flash speed calibration yet. At this point I don't even care anymore. LOL

 

Not caring is definitely cheaper!

The Hypertech 4Runner unit is about $250. I can imagine them upping that for the Tundra. I'd probably buy one for around $150, but at $250, it tilts my "don't care" scale also.

 

There you go. Assuming you have the 20" rims on your limited and went to a true 35" tire. Granted that 35" means different things to different tire mfgs, but this is still directionally accurate. Enjoy.

 

How much does it change your estimated gas mileage that the truck displays? I was wondering what kinda of mileage I was actually getting. Truck says 14.1 mpg with 295/60/20

 

Not sure butbtehbdealer I bought mybtires from said they would re program it, this was included in teh price of the tires.

 

Like a great cook, why measure your speed when you can just feel it.

 

Ignore it until the PoPo stop you, then cry foul on your speedo. Last 5 trucks had larger tires and I went off Speedo and still got passed a ton

 

Not sure if id trust waze fully, im completely stock and at times waze says im doing 5 mph faster than my speedo, and then on the same drive will be dead on to it. Maybe some sort of interference from something, but it CAN be inaccurate.
