Hello,

I'm new to the BMW world and just bought a 2013 E70 X5 Xdrive35i. I have a lot of questions but I will try to be brief for now.

1. What is the largest side wall tire I can run to improve ride quality? Currently have black 21" factory wheels

2. Best mods to start off with? I've seen hints about the MPPK tune and MPE but cannot discern enough information.

3. I live in the Dallas/FtWorth Texas metroplex (more FtWorth side) so if there is anywhere I can be pointed to to have some of these things done or for general maintenance I would appreciate it.

Thanks,

Mike
