4/4 with 20s

btipsword · 04-07-2008, 12:51 PM

So I'm wanting to go 4/4 on my 2 dr jimmy with 20s but really have no idea what size tires I should go with.. I'm not a big fan of wheel gap.. haha. I came from the import world and somehow wound up with a jimmy so you guys'll have to help me on this one!

I had some 20" coys with 345/40/20's. They fit perfect, but the backspacing was wrong on the wheels so they rubbed, but looked perfect.

255/35's are also a safe, but but don't offer as much wheel protection

Ive got about 4 inch drop, 20" coys, 245/35/20 rims with no rub. But i have very little sidewall protection

im the same as you, i had a cavalier show car that was 2 inches off the ground

now i am 2 feet LOL so i am doing the belltech lowering kit on my jimmy 4 door 4X4 and i am doing 20s with 245/45/20 rubber

here is a good tire size calculator all you do is put in the factory size and you can play with the numbers to find the best fit. the size i chose keeps the same speedo reading and overall diameter but are a little wider

hope this helps

Just around town, I just looked, they are 245/30/20.....ride like crap

ZQ8 Blazer · 04-12-2008, 04:53 PM

Tire size calculator:
i.e. 245/40/20

245x40=9800
9800/2540=3.858 total sidewall height
3.858x2=7.716 total of both sidewall heights
7.716+20=27.716 total overall height not on vehicle
27.716/2=13.858 total height from center of hub to top of tire.

What year is your jimmy?

Don't drop a 4wd please. I mean please don't, it's just unpatriotic

Darkside · 04-12-2008, 05:19 PM

it is a 99 SLS and it will be raised back up in the winter

ZQ8 Blazer · 04-12-2008, 05:22 PM
