Effects of Replacing Rims with Smaller ones.
Hi, I currently have OEM 17x7.5 rims fitted with 235/55/17 tires on my 2002 STS.
I want fit 16x7.5 OEM rims fitted with 235/60/16 tires.
What adverse effects will this have speedometer error, handling e.t.c.

Should be very close to the OEM diameter. Tread width may be a bit different, depending on the manufacturer.
Ya it should be very close, it's not like you're going from 17" to 20" or back down to 13".
btw what's so bad about the stock 17" rims? The 16" looks just a tad bit too small on the Devilles IMO.

There are many 17 to 24 wheels and tires with the same 'actual size' as far as circumference goes.
Stock tire = 265/70R17, rolling circumference =99.29"
Big Tire = 305/30R24, rolling circumference = 98.03"......smaller

packer,
the tires you mention would be different by .3%, that is the speedometer equivalent of one mile per hour difference at 300mph. They are the same size excluding where they meet the wheel.

From this and your previous reply, i see you have a great deal of knowledge of my question,
May i ask in order to educate myself further, the formula/method you used to obtain these numbers?
The rims are badly pitted and the chrome is shot on two of them.Ya it should be very close, it's not like you're going from 17" to 20" or back down to 13".

I can not find any one in the UK to refurbish them due to enviromental issues with the chemical process.
I have unable to find any one willing to go the post office and ship me an OEM set using economy mail. The very few companies that will ship here will only use their shippers (Fedex, UPS e,t,c) And the cost is $400.00!
I have seen some very nice 16" ones on Fleabay, I am waiting on a reply from him.
235= tread width in millimetersAs my friend Mr Spock said "Fascinating"...

x
55= aspect ratio between tread width and sidewall height. Sidewall height is 55% of the tread width, or 129.25mm high. Remember that there are two sidewall measurements to take when figuring tire height (above and below the rim).
x
17= wheel diameter.
So, take 235mm and divide that by 25.4 (millimeters in an inch). It is easier to figure in inches to us Americans. That gives you 9.25" tread width. Multiply 9.25 by .55 (aspect ratio) to figure distance from rim to tread. That gives you 5.0875". Since there is sidewall above and below the rim, multiply 5.0875 by 2. That gives you 10.175". Add the wheel diameter which is 17", and you get 27.175". That is the tire height.
The formula works for all tires. So a 235/60/16 figures like this,
235 divided by 25.4, x .60, x2, +16.
That equates to 27.102" diameter tire.
Your difference comes out to be .073". Not even enough to mention. That is like 2mm.
So in basic terms, a 235/55/17 tire, and a 235/60/16 tire, are the same size.
