Tazer Tire Question

[NY Andrew]

Sooo tire setting of Tazer shows 33.455 which from their explanation is the OEM tire size. I have new tires and the main reason I purchased this was to change tire size for speedometer/shift correction.

I went from the:
OEM Goodyear Wrangler SR-A P275/60R20x9/
TO Nitto G2 LT305/55R20/10
still with stock OEM rims.


From my understanding the height actually potentially dropped 0.3” going from the 60 to a 55

What would the height be?

Go to the tire manufacturer's website and look up your exact tire and they will have it listed. Every tire can be different even if they are suppose to be "the same" size.

It didn’t have the height. I actually even called and asked for the rolling height and they said it varies based off rim and the inner barrel of the rim..... I said well couldn’t I just measure from ground to top of tire and he said yes but of course that’s with all the weight on it too. Normally they great with numbers when I’ve called them in the past; wondering why it’s so hard to get rolling tire height.

I just look on the website and inflated overall diameter is 33.23" on a 9.5" so that's only a .225" difference. I'd start with the 33.23" and then check your speedo vs gps.

G2’s spec out to 33.23” per Nitto’s website, factory Goodyear’s are right at 33” on their website. This of course is unmounted but the size is so close I doubt the speedo would be off by much if any...........

There is something like a 2% variance allowed anyway

^^^^What he said^^^^

Not enough difference to worry about adjusting anything.....

 

[NY Andrew]

Damn I really thought these bigger tires would need a speedo adjustment but apparently the height is less which is so hard to believe! Eh guess I’ll keep the unit to disable weather alerts and fold my mirrors in I guess hah. Still need to check the DRL if it works.

Thanks guys!! Guess I’ll just leave it where it is. I can’t see adjusting fractions of an inch affecting the speedo at all.

It’s funny cuz most of us dump on the stock Goodyear’s but as far as size goes, they are the tallest factory tire on a 4th Gen Ram..........

Tires on the Rebel are like 0.2” smaller. It almost insignificant but the crapyears are a smidge taller

I loved the white wall letters, look really sporty with my blue, but just not a safe/good tire for a real truck. Prob a dope SUV tire though.
