32" front - 33" rear

[fourocker]

Hey fellas relax, just an idea i had, FYI i grew up on farms and with 4x4`s.
Glad to have hit a nerve on a few of you though, or should i say don't take life so serious.
I would have thought that if a mix of 32" and 33' were so bad what about 285`s Vs 33" rear? its a much closer mix.

No worries, I am relaxed, I was laughing whilst typing because it seemed a funny idea. There's nothing wrong with thinking outside the box now and then, just not on this occasion, the rule for fourby's that shouldn't be played with. I re read my post and it does come across a bit rough.

Would a taller narrower tyre fit better with less rub? If you really had to be different you could run a 235/85/16 front and a 285/75/16 rear. The 235/85 will be about 3mm taller than the 285/75 but 50mm skinnier. I wouldn't do it tho.

285 what?? because a 285/75/16 IS a 33" tyre

and like someone else pointed out earlier the profile number on your tyre eg, 75 is a percentage of the width of the tyre eg, 285

So for a tyre that is a 285/75/16 it would be 285 = width, 75 = percentage of said width, 16 = obviously the rims radius or if you prefer the size of the rim in inches.

From what i believe its actually not the same, check out this link and ill show you.

I`m no expert but from this site it states there is a difference, but its on the internet so it must be true!!!

What are you on about?

In metric sizing the aspect ratio is a percentage of the tyres width, not the size of the rim, ie for a 285/75/16 the height of the tyre from the bead will be 75% of 285mm.

Imperial sizing is pretty straight forward, 33" diameter x 11.5" wide.

You're both trippin. Just use the same size tyres both ends ffs

Instead of not knowing wtf is going on and having to use a tyre size calculator I suggest people learn to work it out in about 20 seconds using a calculator.

to quote myself from another thread

http://www.navara.asia/showthread.php?t=18917

ie: 33x12.5r15 =

33*25.4 = 838mm
12.5*25.4 = 317.5mm
r15 = r15 no surprises there


its a tad harder converting back to inches from a 265/75r16 but this is all you do.

ie: 265/75r16 (265 is the tyre width and 75 is the aspect ratio of width to wall height its 1:0.75 in this case r16 is just the wheel diameter in inches..again no surprises there)

265*.75 = 198.75mm (this is your tyre wall height)
r16*25.4 = 406.4mm
sum of the sections
=198.75*2 (upper and lower walls of the tyre) + 406.4 = 804mm
804mm/25.4 = 31.7"
265mm/25.4 = 10.4"


obviously these figures change per per tyre manufacturer but the method of converting to and from remains the same.

^ exactly.

"What im on about" IS,, tyres that read 285/75/16 = 32.8 x 11.22 r 16
so i call that closer enough to 33's as most places do,
Ok its not EXACTLY 33' it is actually 32.8" ,,
but seriously .2 of an inch is about as long as you dick so im not "trippin" as much as you you obviously are.

And at no stage have i said the guy should mix his tyre sizes up i just was pointing out to him that his remark "what about 285 verses 33's"

here is a simple table for all to look at with out the calculator


255/85R16 = 33.1x10R16
265/80R16 = 32.7X10.4R16
285/75R16 = 32.8x11.2R16
295/75R16 = 33.4x11.6R16
305/70R16 = 32.8x12R16

yeah, you're right. sorry for some reason I misread you saying aspect ratio was related to rim size. Im trippin. my bad. And yeah, I was thinking the same thing that a 285/75/16 is basically a 33.

ah ok all good, and in that case i retract the statement about the size of your dick being .2"

 

[OneMofo]

HAHAHA Why so serious?? you guys crack me up, i was just nit picking sorry for ****ing you around, my idea was very out of the box, obviously it wont work for many reason previously mentioned.
I decided to nit pick and show that 33" is not EXACTLY 285 and so forth. i`m glad to have created so much interest. Oh and just for the record i don`t use that site i just came across it on another 4x4 site and thought it would prove my point.
Glad to be on a site where there are a few guys who do know what they are talking about.

 

[ben85]

go 33s and just cut the front guards, or just stick with 32s and you wont have any dramas.

 

[OneMofo]

32`s it is for now till the next set, then ill look into steel rims and 33`s.
Cheers ben

why dont you run 31", 32", 33", and a 35" on each corner and keep a 21" rim with extra low profile as a spare
