Will these tires and wheels fit
 

On my 2010 Ranger Sport 4X4 will they mess with my 4wd system or is it safe ?.

4 x Pro Comp Mud Terrain 31x10.5x15 ON
4 x RCX Steel wheels - 5 x 4.5 bolt pattern, with 3.75" backspace

They were on a Jeep TJ...does my ranger have the same bolt pattern.
Is the backspacing good ?

Thanks sorry im a newbie in all of this.

Yes rangers have the same bolt pattern as a TJ. those 15x8 wheels prob are.. and yes they will fit fine hell you can go 32x11.5x15 with no problems stock

Yeah those 31's will fit no problem.

Yep they will fit and look damn good on it too... Make sure you post some pics when they are mounted

you'll love those tires, Ive had a set since '07 and theyre about 1/2 tread
