i have no idea what this is. and i want to get the MB Gunner 5 for my 99 f150. what offset and backspace do i need for these to fit? Thanks in advance

 

Link

I dont know as much as most but do know we'd need more info. Is it 2wd or 4wd? Lift or level kit? Tire size? etc.

 

thanks for the link...its 2wd with 2" drop shackles...i dont know what tire size i will need either.

 

Most smaller and off road style wheels for the 97-03's will have 4.5 inches of backspacing just like the oem wheels. Most of the larger, street style wheels will have more backspacing to tuck the tire in. What size wheels are you looking at (diameter and width)?

 

im looking at the MB Motoring Gunner 5 in 20" x 8.5" i want to use it as a street rim. i dont know if its made as a offroad rim or not

 

4.5 or 5 inches of bs should be fine with an 8.5 inch wide wheel.

 

ok...umm sorry for the ?s but i cant seem to find the backspace for that wheel to save my life. all i know is its -6 offset. does that matter?

 

Not to hijack but this thread reminds me to ask Wandell if you had the choice for an 04-08 screw, would ya go with 44mm or 30mm B/S on a 10" wide rim? Seems to me unless I am backwards in my logic, the 44mm B/S would put more rubber inside the fender wells and the 30mm more outside, correct?

 

According to this chart, those wheels have a 4.5 of BS.

 

man yall are awesome....thanks guys

 

a negative six offset will give the wheel a large lip, and have the face sitting further back toward the backside of the wheel.
A 0 offset would yeild a 4.75 backspace.
6mm = .24" so you are right at a 4.5 backspace.
Your wheels should fit just fine.
That is correct, the 44 offset will put 14mm or .56" more of the wheel and rubber to the inside.

With a ten inch wide wheel, your backspacing at 30mm offset is 6.7 inches.
at 44mm it would be 7.26" of backspacing.
I am not sure what max these trucks take without rubbing so you may want to measure to be sure. I believe you are talking about the saleen 30/44 setup correct?

Its just a matter of preference there, the 30 will stick out just a bit further than the 44. I personally would do the 44 if you dont have factory flares. they throw dirt/rocks/water all over the fenders. I have 35 offset on my 22x9.5 which gives me 6.65 inches of wheel inside the hub and 3.85 outside the hub and they stick out past the fender lip just enough to be annoying when its all cleaned up and i go thru water.

DOH took too long to post!

 

thanks for the info fabian..i appreciate it

 

Thought so, thanks!

 

ok so now i know these wheels will work. i want a decent amount of sidewall but not too much or not like rubberband tires. hopefully yall know what i mean. maybe something like 285/50R 20 or 295/45R 20?

 

Thats an easy one... this involves a bit of math so just bear with me.

A tire size is made up of three sets of numbers the first and usually the largest, is the width of the tire in MM.
the second is a ratio of width to sidewall hieght.
and the third and most commonly known is the wheel size.

SO with that being said,
1mm = .04" and 1" = 25.4mm

Your first tire size states 285 wide making it 11.4 inches wide.
the second number is a percentage of the first... in this case 50%
so you would have a sidewall of 50% of 11.4 = 5.7 inches.

calculating it using the second set of numbers would yeild
295 X .04 = 11.8 inches wide.
the ratio is 45% so
45% of 11.8 = 5.31 inches

Your first tire is going to have .4 (.39 exactly) inches more sidewall.
and will be about .8 (little over 3/4) inches taller.
