I accidentally posted this in a different forum, but hopefully it can be answered here:

Hello All,

First post and new member of the form - you all talk about great stuff!

I'm getting a 2005 Accord LX and wanted to put stock 2005 Accord EX alloy wheels on them. The tire sizes are slightly different: the LX is P205/65R15 and EX is P205/60R16. Is that a problem? Or am I going to have to completely change the tires AND the rims? Is the larger tire size also going to mess up the current set-up/suspension...I don't want the tires rubbing against anything...

Everything is stock on the LX - nothing fancy.

Thanks,

James

 

You obviously have to go to 16 inch wheels to have 16 inch tires. Wheel and tire will have to be changed but your speedo and odo error are almost nil.
Here's a quick comparo of the two. At 125 mph the speedo will be off by less than 1 MPH.
