There will be a problem if instead my original tires(175/75/13) I put 185/85/13???

 

Thank you allot, all members.

other than the spedo being out i dont foresee a problem

Yep, your speedo will be off about 5 miles per hour at 50. there shouldnt be any problems.

Do you want the extra circumference of the tread? If you just want a wider tire than the 175/75-13, have you considered 185/70-13, which should be approximately the same height/circumference as the 175/75-13.

Thank you. This tires I will buy..

 

A nice day.

just make sure you put them on all 4 wheels. important to keep the tire diamiters the same in order not to mess up the 4wd durring street use.

Nice app here to give you the exact error:
