Just a really quick question...

I'm going from 225/45-17 (Toyo Proxes4) to 225/50-17 (Nexen) tires for my '99.
Getting the Nexens for dirt cheap, $231 for the set.

I wanted to ensure I wouldn't have any problems. I searched extensively and couldn't find any negativity towards rubbing but there may be some speedo error, which I can deal with.
I am really only concerned with rubbing though since I have an Eibach drop, which is fairly mild.

Any help/advice is helpful.


I just put a box with 3-JL 10s in the trunk and do have mild sagging...but with the extra weight added I am no longer worried about keeping my performance up.

 

I do not think rubbing will be an issue as the width and hight is not all that radical with Eibach springs...

Keep in mind the ideal size is 235/45-17 which is only 0.1% slow on the speedometer reading.

Stock tire size is 215/55-16
sidewall:4.7in
radius:12.7in
diameter:25.3in
circumference:79.5in
Revolutions per mile:797.0

New tire size 225/50-17
sidewall:4.4in
radius:12.9in
diameter:25.9in
circumference:81.2in
Revolutions per mile:780.0

The new tire will provide a speedometer reading ~2.2% slower than the actual speed so when your speedometer reads 60mph it will really be ~61.3mph.
