so whats the biggest i can fit on dakota rims the i guess closed spoke ones they look decent dunno ho wto explain it currently 235 / 75 / 15 ? can i makem a little bigger ?

 

235/75/R15 is the stock size for the early Dakota's. I had the 30x9.5R15's on the original 15x6 rims. Like I stated above, 31's might fit, but might also rub. So to answer your last question, you can go a bit bigger. The tires you have now measure up to about 28-29" tall. 30's fit with no problems. 31's will be tight.

 

ok so there are the tires i have sitting in the house now that i will be putting on the truck when the snow is gone i know they dirty i need to clean em up but i got m ybatteries for cam so i wanted to show you wha trims i have ,,

what about 265 75 15 ? that fit these rims or is that a 30 inch tire :P ?
im stupid when it comes to this stuff sorry lol
and if i use these rims do i still need the 1/4" spacers in the front for the 30x9.5 ? or os thatonly if i go with 31"

 

No you won't need any spacers for those rims. Those are 15x6 and will bolt right on with no modifications. A 30x9.50 inch tire will fit just fine.

 

Try the following link to compare sizes:

Any 6 lug rim from 96 back will bolt right on your truck without any problems.

 

i know the rim will bolt on i was just curious what size rubber i can get on it :P
without having to do mods or spacers etc ~

 

30's are about as tall as I think you can go. Like I stated above, a 31" tire will go on, it just might rub when you turn. Honestly, the best way to try and fit a tire is to go to the tire shop and get some fitted. When I got my 30's, I had 31's fitted, and a couple of other sizes. Granted not all shops will be willing to do that, but all you can do is try.

 

Mine is a 2nd gen and it came with oversized tires on it. I have the 16x8's like the pic you showed and stalk I am running 265/70/16. I did have some 265/75/16 on it, which are about the same as a 32x12.50 and they rubbed back of front fender well slightly, mainly when in a turn and hit a bump. The 265/70 is about the same as a 31x10.5 and again, this is the stalk tire for my truck. Prev. owner ordered it with the larger tires. Look in the gallery and you can see some pics of them on my truck. It is in the Polar Dakota album in members section.

 

Your generation of Dakota came with the 15x8 wheels up to '03 I think, 16x8 there after. They also had the 31" tire stock. I think anything bigger required a body/suspension lift to eliminate rubbing.
