I am about to embark on the journey of Tire and wheel buying. The rims are American Racing RTS 20" 311 series (a.k.a. Black series) . What I need to know is, what is the best tire size to get for these trucks, on this wheel 20" diameter, 8.5 width and +18mm offset(approx. 4.75" backspace).

The stock tire size on my truck is 275/60-17, or a 30" tall tire.

Hey, how is it up there in "Miama"?

It depends on if you are going to lower your truck or not.

 

I couldn't agree more with the wheel dimensions.

As bjh has already asked...suspension stock or lowered?

Also, is it a 2wd and what are you trying to accomplish?

 

going to lower 2 front 3 rear. Most likely. maybe 2.5 - 4. Going for the lowered street cruiser look.

These are the wheel I am looking at getting. This wheel on this truck.

let me know what you all think.

It is a 2wd.

It sounds like you are setting your truck up almost exactly like mine.

With the wheels specs you gave, you could run a 285/50 tire (max) and if you lower your suspension up to 2.5" in the front and 4" or so in the rear (to make it set level), everything will fit like a glove.

 

I ran and still runnin 275/45R20's. My truck is now lowered and looks better but I ran the same tire factory hieght. With the Charger, I going with a larger tire (Wider) in the rear with the next set. By the way, Don't know how good of tire they are, but General Grabbers are only $108.00 a piece at tire rack with this size.

 

anyone else have any input?/

 

Im getting 20s and the tires are going to be toyo 285/50/20

 

I have been in the tire business nearly 20 years. If you leave it stock then 275/55R20. If your drop is 2-3' then a 285/50R20 and if your drop is farther than 3' then a 275/45R20. Good Luck

 

not sure if this will help but it came in handy when i bought my rims.

I have the American Racing RTS Blacks 20x8.5 with 285 50 20R with a 4 inch drop and is running good, but then again ive only had the truck for a bout a week and a half! lol

 

Got any Pics??

Would like to see how they look.

Scotty

 

Yeah Im going to get some pictures up today Lol the truck is hella dirty though. Im going to go try to clean it and get some pics up.

 

In chrome instead of black but you can get the idea. I'm running 275/45-20 Goodyears and am lowered 3.5/5 with the DJM kit.

 

looks real good Stephen00GT. I am hoping I like the look of the black on black on my '98. I am going to lower first then when my tires, which are 6 months old, need replaced I will order the new Wheels and tires. Thanks for posting pics, gives me a real good idea what mine will look like.
