Tacoma - OVTUNE - VFTUNER - Update Info and Original Development

The sport has 17” wheels. The off-road has 16”.

265/65/17 on sport
265/70/16 on off road

Same diameter. Different side wall size to accommodate the different rim diameter.

 

Alright, serious question here. Learn me up please because apparently I've been learned up wrong. How does a 1" difference in wheel size result in same diameter with the 65 vs 70?

 

The 65 and 70 is your side wall size. The higher the number the taller your tire

 

Yeah I get that. But how does that correlate to equal diameter with different sized wheels? A difference of 5....what, percent?... seems so miniscule

Does that really make up that large of a difference?

 

This is easiest way to understand what’s going on. Punch in some sizes and it’ll show you all the dimensions

 

Thanks man

 

That is correct.

 

I definitely beat my head against the wall for a while trying to make sense of it and understand the meaning behind everything. Being able to visualize and compare made it a lot easier for me.

 

Yeah I usually need to see it to wrap my head around something. Cuz eye arr dumm

 

265/65/16 vs 265/70/17

 

You have the aspect ratios flipped

 

Sorry lol! Little to much to drink apparently!

 

I think we all can forgive

 

Finally someone who knows the correct terminology...lol

<<<<< Works as alignment tech/mechanic for tire shop.

 

Second number is a ratio, not an actual measurement.

 

The second number in the tire size is the aspect ratio, and tells you the sidewall height as a percentage of the tread width. So, you multiply that by the tread width to get the sidewall height in mm (on one side of the tire). Multiply that by two and divide that by 25.4mm to get the total sidewall in inches. Add the wheel diameter to get the total diameter.

265/70 R16 = (265 x .70 x 2)/25.4 + 16 = 30.61"
265/70 R17 = (265 x .70 x 2)/25.4 + 17 = 31.61"

So as you can see, the only difference here is the 1" difference in wheel diameter.

 

man, i'm starting to think the uber smooth tune will never be released.

 

lol

 

Well, it'll be released WITH the auto trans tune via flash manager.. so you're almost right lol.

 

why auto only?
