Sorry Im at work and no time to try and figure it out myslef, you guys are very knowledgable so I hoped you could help.
I want a Nitto 420 or 555 tire, I just picked up a set of the Chevy NNBS 20's and im leaning towards a 4-6 drop at most for now but may do a 3-4 to keep wife happy.
My truck is a 2002 RCSB Chevy all stock.
I dont want lower tha a 40 series tire if thats possible, not sure what width to get.
Thanks in advance now I better get off ths site and back to work haha

 

everybody usually just goes with a 275/45/20.

 

Just checking in real quick, thank you for the response.
I was hoping for that size, wasnt sure if I would have a problem with 275's all the way around since im putting bigger wheels and dropping it.

 

275/45/20 should fit perfect on a dropped 02

 

ugh, on Nittos site the only size close to that in 420s is 265/50/20 or a 255/45/20

 

Ive got 275/45r20s on mine and all I have is drop shackles.

 

to figure out the diameter in inches use the equation:

(tire width*2*aspect ratio/25.4)+rim size

 

so for a 275/45R20 will be:
275mm X .45 = 123.75 or 4.87 in
4.87 X 2 = 9.74 in
9.74 + 20 = 29.74 in tire.

 

yep...

 

Seeing a lot of 275/40/20 with a 4-6 drop
Suggestions on tire brand since it seems I can't buy Nittos in that size?
