305/70/17-spacers-stock wheels

Howdy,
I want to put 305/70/17 on my stock wheels. I do have the 1.75" TF leveling kit installed. I cant find a straight answer if I will need spacers or not. Any advice or recommendation is greatly appreciated.

I have 285/70/17 on my stock rims and had to put 1.5 inch spacers because they rubbed without. After spacers, no issues for me. I have a 2.5 BB on it too...

You will need 1.5" spacers with the stock offset.

I'm not looking up all the tires... but, I'll go out on a limb and say 305/70R17 needs a 1.25" spacer.

I think the max width on stock a OE wheel is 11.5"...

correct me if I'm wrong...

Toyo AT - LT285/70R17 = 32.8 x 11.5 [RIM 7.5-8.5-9.0]

Toyo MT - LT285/75R17 = 34.1 x 11.6 [RIM 7.5-8.0-9.5]

BFG KM2 - LT285/70R17 = 33.0 x 11.5 [RIM 7.5-8.5-9.0]

BFG KM2 - LT285/75R17 = 33.9 x 11.3 [RIM 7.5-8.0-9.5]

BFG KM2 - LT305/70R17 = 33.9 x 12.2 [RIM 8.0-9.0-9.5]

What are you referring to? like help you understand the numerical denotation of tires? If so,

305 is the tire width in milimeters so 12.00in
70 is the aspect ratio in % so 70% of 305 is 213.5mm or a sidewall height of 8.4in
R means radial
17 is the rim diameter

So that tire is, 17" + 16.8" (for the sidewall height x2)= 33.8" with out bearing a load.
