Hi guys,
My dad has a 1998 C43 AMG Mercedes that could use some new tires.

Currently has:

F: 225/45/R17
R: 245/45/R17


I have some old tires that I was going to put on my S2000, but now they are just collecting dust.

They are:

F: 215/45/R17
R: 255/40/R17

I would give them to my dad if I was sure they will fit fine.
Sure it has less traction in the front, and more in the rear. That might effect handling, but no big deal.
I don't know his rim widths, but I can tell by looking at the current setup, both the wheels and fenders can physically take these tires.

Will the rear cause a speedo error?
Any other negative effects of this tire change?
Any input appreciated. Thanks a lot!

 

Bump?

 

the speedo might read a little off, but I dont think your dad would mind....

 

You would throw off the anti lock brakes. The set up you are looking at would be shorter than stock in the front and taller in the rear.

 

So should not use?

Thanks a lot, Jim. And AP2.
