check out my car

i have 225-40-18 on 18x7.5 rims
i have eicbach pro-kit
i have the RAZZI GFX
it will throw off your speedo by like 1MPH, thats it, 225 is not much higher than 215

i got an alignment after the suspension, but thats it, and the same rules apply, no need for another alignment unless you hit a bump hard or something.

Hi... for the speedometer change check out this usefull link:
Tiresize calculator
Compared with the 215/50-16 stock tires the difference will be about 2.5%...
Have fun
