To compute the height of any tire, multiply the section width by the aspect ratio ( as a percentage ) times 2. The result is in millimeters. Divide by 25.4 to convert to inches, and add the wheel diameter - that's the height. For a 235/55-17, standard Azera Limited tire:
235 x .55 x 2 = 258.5mm, divide by 25.4 = 10.177 inches + 17" wheel, gives a height of 27.177". Tire Rack lists a 235/55-17 as 27.2"
Now that you're bored to death, keep the aspect ratio and wheel diameter the same, and increase the section width and the answer ( height ) will increase.
Tire Rack lists a 245/55-17 as having a height of 27.6"

speedo error not significant with these differences

Speedo difference of 1-2 MPH at 70MPH...but since the 235/55-17 is a lot of tire to start with, IMO, there's no reason to get a larger size which would cost more, weigh more, and reduce acceleration due to the added weight and the effectively taller gearing.

cool. thanks for the lesson

weight diff is not significant, cost is same or less , acceleration may be better with larger contact patch on the road......are u more concerened with acceleration (drag racer) or fuel economy (taller gearing) get some of the extra weight you're hauling around in the trunk out and avoid "jack rabbit starts" enjoy the better handling and smoother ride of the wider tires....

Here's an article from C&D magazine concerning larger and heavier wheel and tire assemblies.
Please note acceleration and fuel economy are reduced as tire sizes go up...comparing prices at TireRack, larger tires of the same brand and model almost always cost more unless there's a sale going on....transient handling response is poorer with a taller sidewall. Isn't America great: we're all free to have a preference and buy what we like.

key take away here is "extremely low profile tires and heavy aftermarket wheels" I don't think this is an issue with OEM or similar replacement tires that the original thread dealt with
#579 of 581 JERKY UPSHIFT FROM 3 TO 4
Feb 01, 2013 (9:16 am)
My 2007 Azera now with 145,000 miles has developed a jerky shifting problem (automatic shift). It occurs after highway driving and slowing down at a tollgate, without coming to a halt (EZ pass gate). Upon acceleration there is a moderately serious jerk in shifting from gear 3 to gear 4.
Dealer service people did not detect any faults and reset the defaults in shift-values. the problem did not go away.
any suggestions you have are very welcome!

I had my Yoko AS530s installed. I found them at Merchants (was told that the AS530 were made for Merchants and affiliates, like tires are made for SAMs or COSTCO. The Yoko Avid Envigor and is what comes up at the Yoko site for the Azera; this tire is similar to the AS530 and is available at Mr Tire. However, the AS530 has slightly better specs. So far, so good. The ride is smooth and the noise is gone. Thanks for the advice.

Bought my AS530's Tire Kingdom 3 years ago for my '06 Azera and they are GREAT tires.
