Hey guys. Ive been looking for some new tires on CL because im short on cash and low on tread lol with winter right around the corner im running out of time. I found a decent set of wheels and tires id like but, theyre 265-70-16 and im running 17s. Obviously i cant just use the tires, but i was wondering if going from a 17 to 16 set would mess anything up? Like how far would my speedo be off if at all? I know it wont hurt my drivetrain at all since theyre all matching tires and size. Thanks guys!

 

Speedo will be off. Heres a site that should help you out. It compares the 2 sizes and how much overall difference there will be:

265/75/16 which is a 31.65" tire and 265/70/17 which is a 31.61" tire are pretty closes sizes to each other. wont even notice it. Turning your truck is a bigger mileage change than these to tires compared together.

 

Do you have FX4 wheels?

 

I do not. I wish i did though. I wouldnt get rid of them. I just have "normal" wheels

 

actally u have the "4x4 Offroad" package. same as fx4, accept the 4x4 offroad was offered 97-01, and the fx4 package took its place in 02-03. the wheels are different.
