tire size

[cas1]

i've got a 2004 mach 1 without any suspension mods. i'm wanting to put 18 x 9 saleens on. i want to run 265-40-18 for tires. is anyone running on these? are there any problems with rubbing or any other issues?

the sidewall will be 5% in mm of 265 taller than stock recommendations. Most run a 265 35 18. On the back it shouldn't cause any issues but the speedo will be off a bit.
