wheel upgrade

[missam]

hi guys, my bro had a set of 15`s (http://www.partstrain.com/Shopby/Department) on his accord but if he`s gonna put on some bigger tires like 17`s or 18`s how do we make adjustments? are there important pointers when upgrading tires?

Well you won`t rub with either of those sizes at stock height, but unless you want it to look really stupid, you will need to lower it. take into account wheel width, offset, and tire size as well.

And remember that if the new tires are taller/shorter than the originals you`ll have to recalibrate the speedometer. Carry lugnuts that will fit the spare, the ones for the new wheels probabl won`t.

Go here to calculate tire size.

If there`s only a 1% or 2% difference in overall diameter, no need to calibrate the speedo. 2% of 70mph would only be 1.4 mph.
