wheel/tire specs help needed
Hi guys. Long time member but new to this body style. Picking up a 2000 GMC 1500 2wd extended cab that the previous owner lowered. Im guesing its a 4/6. It still has the stock wheels and tires. Im looking for low cost wheel upgrades. I noticed later model OEM wheels is a popular option and some look great but what specs do I need to look at? I know its a 6x5.5 bolt pattern but thats all I know. Looking at 20" wheels, how wide can I go? What backspacing? And what tire size will fit front and rear? Not looking to go much shorter than a 45 series sidewall. Thanks for the input

Re: wheel/tire specs help needed
Most of the factory rims are 7" wide. I think the 18s or 20s are 8". Figure your current tire combo, height then calculate a tire combo on the other rims that have the same height and you should probably clear OK.
Such as I am guessing you have either 235/75x16 or 255/70x16 which is a hair over 30" tall. On an 18 inch rim a 255/60 ro 265/60 would keep you in the hair above 30" tall combo. ON a 20" rim a 255/50 or 265/50 tire would keep you in that range. I do not know of hand what was the factory size tires on the newer 18" or 20" wheels. I had some Nissan 17"x 7.5" alloy rims on a couple my trucks. They fit well and I was running a 265/65x17 tire which kept it in the same height range.

Re: wheel/tire specs help needed
If you are using stock style rims, you shouldn't have any issues with BS and width.
The white aftermarket wheels (16x8 with 265/70) I had on my 02 I loved, but not sure they would work on a lowered truck.

Re: wheel/tire specs help needed
That actually makes perfect sense and didnt think about that. But I'm not sure if I'm going to use OEM or aftermarket yet. Wheel selection in 6 lug for my taste is pretty limited.

Re: wheel/tire specs help needed
I know full sized Nissan trucks/SUVs work on GM trucks. Not sure about Toyota or Ferd 6 lug. Biggest thing would probably be the bore size. The Nissan is just big enough, but I think the Toyota might be a little smaller. Just not sure.
I didn't have lowered trucks (too many crappy roads and trails where I drive), but the one thing I didn't care for one the GM 16 and 17" wheels as they were only 7" wide and I wanted a bit more width. I found the Nissan Titan/Armada rims by chance and like them for stock style.
