Curious as to why the rears are wider than the fronts? Would running 4 equal width tires do any harm? Rather than 8/12 fronts and 10/12 rears, could I run 4@ 9/12?

 

No harm and yes you can run 9 wides all the way around

 

i go up on the width with everything i get, it will casue no harm. I normally go up inch all the way around i have 10/12 on front and 12/12 on back, my buddy has a 350 4x4 and he has 27/10/12 all the way around and its all the time 4x4, it does great

 

Thanks. The rears are listed as a 10/12, but really measure 9.1". Gonna swap a rear on the front, see if I will need spacers. Slowly saving for reptile radisls, 26 9 12.

 

id get 10s are the way around but like i said thats just me, worst case you might have to buy some small wheel spacers

 

I was just thinking that, if I need spacers, why not go 10's all around.

 

exactly!

 

A lot of mudders have gone skinnies all around, 9". The guys duck hunting the rice fields have opt'd for 7" all around.

 

Few reasons , Thinner means lighter so it has easier steering.
Thinner do not push as much snow and mud and break a path for the wider rear tires.
The rear drive train is more heavy duty constructed then the front diff and axles so it can handle turning heavier wider tires.

 

Thanks. I may go with 26/9/12 on all 4 corners. My rears only measure out to 9/12 anyway.
