Well its time for new tires and I was wondering what size you guys put on your oem rims. I was thinking of buying 225/50/16 rather than the original size of 215/55/16... Would you guys recommend that upgrade? Thx.

 

I'm getting that size for my Yoko AVS ES100. The error to the speedo is minimal.

 

go for it i just did the same upgrade and they fit fine and like StygianMax the speedo effect will be minimal

 

They actually are my favorite size for the Maxima.

I've tried:
245/40 18 *Looks only
235/40 18 Felt good.
225/40 18 Too thin, what was I thinking!
225/50 16 They will fit your 16X6.5, look good on 16X7s
215/55 16 stock SE
215/65 15 snow tires only
205/60 15 *my second favorite size on the Max (track)

 

Wow, that's a lot of rubber you've gone through. Thx for sharing the experience with us all.
