Wheels and Tires?

[movieman90]

I want to put 20 inch rims on my 99 Explorer, rwd, 2door. Is the bolt pattern 5 by 4.5? And what size tires am i lookin at? I was told, that if i were to put 20 inch rims on the explorer that it would ultimately throw off my speedometer... is that true? any advice would be much appreciated

mine are for sale...cheap

Most go with a 275/45/20... mine are 275/55/20-more sidewall means a smoother ride.
It will throw off the speedo, but not terribly.
