16 with a 17 option i believe. look inside the drivers side door, there should be a label, there it will tell you what the stock tire size is.
the off road came with the 17s like i have on my truck, but i was runnin 265/75's on the stock 16s, and had no problem, then i switched to the 33x12.50s i have now with out my leveling kit, and no rubbing, though on the off road rims. but you should be alright.

 

16x7's unless it has the off road package, then they are 17x8's.



To the OP, install the tires and drive it for a few days. If they rub (which they very well may), then lift it.

 

I just put a set of 33x12x50's on my truck but on a 5" rim. Even with a 2" leveling kit when I have the wheel turned all the way they rub a little bit on the inside plastic.

[quote=Relex;1810602] ... but on a 5" rim.



Hmm. You sure about that? You mean 15"?

 

Yeah missed my 1 key.

 

relex, where can i find some rims like that to match my black truck? are those the 15"ers u wer talkin about? sweet ride btw

 

Bigger tire= less power,more fuel,more ware on other parts.

 

ive got 285 75 16 kumho kl71s on mine...no rubbing...ever so far.

 

Just had Nitto Terra Grappler 285s put on my stock 1500 using stock chrome 16x7 rims and they fit great with no rub. Power loss is barely noticeable. In fact, it seems to keep rolling better. And they aren't 33" tall. Website said 32.67" but when I measured the length it took to make revolution (for adjusting the pcm via the Hypertech) they measured 31.5". Not much different from my 265s.

Get 'em. The truck will finally look like it should have from the factory. You may want a leveler installed just for cosmetic reasons. But you won't need it. And who keeps spreading the rumor the Sport packages came with all kinds of upgrades to the suspension??? It was an appearance package people!!

 

yea i got the 2001 1500 off road sport and the label on the insade door panel said 16" x 7" wheels.
