255/45/20...will it work?

Postby dross93ranger [OP] » May 16th 2011, 2:06pm

I have been messing with a tire calculator for 2 days to the point to where I am giving myself a headache lol. I see where most people with 20s are running 255/35/20 tires. I am not crazy over this look because it leaves too much fender gap and not enough sidewall. My van is a 2wd 2000 which is stock height and I was wanting to run 255/45/20 tires on a 20x8.5 wheel. Will this work?

i know what you mean about the 35 series tire. Been there done that. I learned the hard way. I just pick up some new wheels and tires. Went from 20x8 0 offset with nitto nt555 245/35-20 to 20x8.5 8+ offset with parada spec x 255/40-20 and let me tell you what a difference. I am glad i went bigger. Some websites suggest 235/45 or 245/40 or 245/45 or 255/40 and or 255/45. I think 255/45 will work for stock height. When i had my first 20x8 on stock height i had alot of room. But when i dropped it down 2 inches in the front and 3 inches in the back. I had to roll the front lips on the front fender. Letting you know if you plan to drop to drop yours in the future.

How long does a set of tires last you?
Just called my shop and they were kind of appauled that I would do 20"s on this van. They were like: "You will be changing tires every few weeks". I take it their comments were related to the weight I carry in the back.

Does going up in wheel size come with that side effect? (lower thread life?)
Anybody?

PS: Are you selling your wheels now that you have a new combo?

Havent heard back from misterfx8 in a while but I am now certain that using the 255/40-20 will more than likely cause you trouble and modifications will be needed.
I would love to know how misterfx8 got his newer/bigger tires tucked in there just right? He must have done some work to the fender/wheel well when he lowered it before?
You can follow the full episodic, dramatic, story on what I am doing to fix the rubbing on my 2001 van here:

https://www.astrosafari.com/viewtopic.php?f=66&t=12112

I am fairly certain that 255/45-20 and bigger will NOT fit at all unless you trim the bumper tips a bit and do some mods to the fender area by the doors.

Let us know how you do, every Astro/Safari is different so what might work for one may not work for the other and viceversa.
