Tires Sizes, 20's - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Expat_dude · 02-02-2013, 12:44 AM

Hello All
I have decided to go all 20's on my 70 SWB (static 2/4 drop)... I am thinking about a 285/40/20 for the rear (11.38"W and 28.94" Tall) and 245/45/20 for the front (9.45"W and 28.66" Tall)
I Should be able to fit a 295 on the rear but I am having trouble finding a matching 245 in the same tread pattern.

Any thoughts???

I like the Proxes, I bet that looks great! What drop are you running?

I was at 5/7 I am in the process of bagging it now.hopefully my ride height will be the same if I did all my math correctly.

I know a few people that run your combo. I have 295/40-20's with toyo proxes on all fours, with a No limit kit up front

Awesome truck Mixermike....whats the color code.

I run 20" all around.
I had to install a 1/4" spacer on the back so the tires would scrub the inner fender with special lugnuts.
