I have a 99 ram 1500 5.9 sport. It came with 16's and the tires are bald. Well I have a set of 32 11.5 r15 M/T's that I would really like to put on it rather than having to buy a new set of tires to fit the 16" wheels.

Is it possible to use 15" wheels on this truck WITHOUT having to grind down the caliper or other parts to get them to fit and work properly?

(If the above is possible, would you say get 15x8 or 15x10?)

Thanks for any help you can provide.

I already answered your pm about this as well, but here it is again: "I don't have a sport, so I can't tell you for sure, but if you do a search on the site it will bring up all the information you need. I never asked before I put 15's on because I had already read enough through searches to verify that I could fit them on mine."

As far as the width of your rim, it is personal preference, but with only a 32x11.5, I'd say an 8 is what you want.

 

If the backspacing is right, then yes. I am running 15x8 and never had a problem.

 

If you have the dual pistons that most later sport models have like mine, you will have to grind the caliper to make it fit. The dual pistons are bigger that the single.
