Tire aspect ratio

[cuervo]

I'm looking at ordering some BFG ALL Terrains off the web. My question concerns the aspect of the 35/12.50 Vs 315/70s.

How close in width and height are they?

I'm looking at ordering some BFG ALL Terrains off the web. My question concerns the aspect of the 35/12.50 Vs 315/70s.

315/25.4=12.4 inches wide.

What size rim?

That's my main issue the 35s are 15 inch tires but I'm looking at some 17 inch rims. Therefor the 315/70/17s are probably what I will end up getting. But just want to make sure they were close to a 35.

315/70/17=34.36 inches

So damn near the exact same size. Thanks a heap!

One more ?

What is the bolt pattern on the 3/4 ton Subs?

8x 165.1

8x 170

 

[resurrected_jimmy]

8 on 6.5" only newer fords run 8 on 170mm

 

[cuervo]

8 on 6.5" only newer fords run 8 on 170mm

So I can assume the 8x165.1 is 8x6.5 then. I need to spend some more time reading the 14bff bible.

great site for info and best place for prices when i needed my last set of tires. www.tyres1.com go play in there. then click on tires/ bfgat or mt / then on the size you want. it will bring up the specs for you to compare.


i just checked the 15" to the 17" you loose .2" going to the 17" but you gain 1/2 ton of weight capacity basicly.

have you looked on ebay for h2 tires and wheels. thats what i got. bolt on and about 500-550 set of 4 all the time. you cant get tires even for that. but your 3/4 ton might need wheel spacers on the front as the h2 rims are 5.5 b/s

And brushing up on your metric conversions

1" = 25.4mm, so yep, 6.5" = 165.1mm.

Na, I'm an American living in America that rejected the metric system, after about a 6 year test drive.

So am I. But some idiot in the tire world decided on a tire measurement system with one inch unit, one metric, and one unitless (percentage.)

Until we get rid of P-metric tire sizing, you still need to know this stuff.

Still haven't figured mine out - 11.00R16

They're 37" tall under a fullsize GM and about 11" wide in the middle of the sidewall.


I'll take the radial metric sizes over this one or the old A/B/G/P/Qxx thing. Q78-15...wtf?
At least the radial metric size is part of an equation that I can do in my head and roughly figure out.

Amen to that. Now remember that stock tires were L78-15 but you could get ZXCBY-12-Q on alternate Tuesdays =))

The military ones have, IIRC, a wide range of *one* aspect ratio, so they're inch-inch-percentage, with the percentage being assumed.

Oh god, almost. Just did some googling, and apparently for sizes ending in "0" (i.e. 11.00, 9.50) the aspect is 92%, but for other sizes (8.25) it's 80%.

So an 11.00R16 is 11" tread width, 92% aspect means 36.24" diameter ... that sound about right, 36x11?

[AJMBLAZER]

No. Unmounted they're about 38" tall and under other's on here's K5's they're 37" tall with good tread. Mine so far seem to be about the same.

Then again this is tire stuff here so when 35's = 33.5" tall that might be perfectly correct.

Yeah ... when an inch ain't an inch. Grrr.

What's the tread *width* like?

[AJMBLAZER]

Hmmmm....good question. BRB...

 

[AJMBLAZER]

9" give or take a bit.

 

[dremu]

9" give or take a bit.

Eh. Maybe the 11 is the sidewall then and I got the aspect backwards... 11x2+16 = 38" diameter, 10" tread width (nominal).

Just thinkin' out loud, hoping I could figger out that format of tre sizes =))

-- A

 

[AJMBLAZER]

I think you might be on to something there. 11.00 is definately the section width.

They also make 9.00R16's (well, used to) that went on smaller vehicles and were basically a 36x9.00R16.

Not certain what the equation is...if there is one.
