How can tire height be so "off"?

[clarkstoncracker]

I just purchased a set of 37x13x15 boggers. They measure 38.5" tall and 14" wide fully inflated.

If I wanted those sizes, I would of purchased them.. How can these measurements be so far off?

Thats interesting, cause the people who I have talked to with that size bogger said they were only 35.5" tall.

depends on the width of rim they are on as well... for instance my 33x12.5 dunlops measure 33" tall (never measured width) on an 8" rim... my buddy had the 35" version, his measured 33" tall on a 10" wide rim, on an 8 they measured just shy of 35"

if you do a little checking you will find that tire height is based on the CASING size minus the tread, its added. the normal depth is about 12/32 in a passenger car tire and 21-24/32 on an off road tire.

They're supposed to measure 36.8" tall, 13.7" wide (not tread width but cross-section) on a 15x10 rim.

According to Interco, the only tire that comes close to 38.5" tall and 14" wide would be the 38.5" tires.... You didn't get the wrong size, did you? (I know, I know, but someone had to ask!)

There's always a pretty big variability, usually they are smaller, although a few swampers are known to run quite a bit bigger.

My last jeep I ran 35x12.5 SSR radials on 15x8" rims up front, and 35x14.5" Boggers on 15x10" rims out back... the SSRs were over an inch taller than the boggers.


My current 36x12.5 SXs seem to measure out right at 36", although they are at 30psi... I'll drop them to 14 or so and see what they do. Stiff sons a bitches, might not compress much..

Only in Bias tires will you see a large difference in diameter based on rim size. In a radial it's hard for it to get bigger based on construction.

Boggers run big.

**EDIT Brian says I'm a retard and boggers run small :tonka: so once again I am wrong **

[Haggar]

35" boggers run small, I know that..

I have Interco 31 trxus M/T's on my Jeep they measure right at 32" on an 8' rim.

Mine certainly did.

The tires themselves will always be off depending on how they're measured and what not. The width of the wheel they're mounted on are also going to change the actual height and width of the tire as well.

why are you complaining? id love to get a biger tire than what i payed for!!!! lol,but i couldnt fit 38"s on the dodge............yet

[Cube]

yea, my 35 inch boggers were small like 34 if I knew that I would have went with 38 or 40

[KILLER"B"468]

CC's aren't the 35's they are the 37's and are the only swamper that is bigger then the size stamped on the tire. Yes the 35's were the only ones that went under the size stamped. All other swampers are true to there size. CC you were telling me you had 39's so I had them aired up to 200psi since they were short.

38x12.5x15 swampers (not SX) run small, somewhere closer to 36".

33" bias run big, almost the size of a 35" radial.

where is darko when we need him, he has to have pics of all these tires next to eachother somewhere
