Hi Luke,

I need your expert advice.[?]
I drive a 1991 W124 200E with original 6.5 x 15 ET38 x 195 tires.

I intend to replace them with 7.5 x 17 ET35 wheels.

1. Will this wheels fit my W124 200E?
2. Which tire will fit better
a. 225 x 45 x 17 or
b. 205 x 50 x 17
3. What tire pressure will you recommend for front & rear for option 2a. & 2b.

Looking forward to your expert advice & thank you in advance.[:)]

Regards

Hi Luke,
My orignal wheels are 15 x 6.5 ET38 with 195/65/15
tires which according to your formula for overal diameter = 25"

If I use 215/45-17 tire size the overal diameter would be = 24.6"
Will that affect my speedometer readings?

Thanks again![:D]

From what I've heard and know, the effect will be very insignificant. Something in the area of maybe a 1/2 a mph. So you'll be doing about a 1/2mph slower than the speedometer will read. If it's even a half. I know the 225s fit in the exact same size diameter, but Luke said they would rub, seemed odd to me. Luke care to fill me in on why a tire with the exact same overall diameter would rub? I was curious as to why.
